Building mixer: types of device, how to choose, manufacturers

Mixer building - a mechanical device designed to prepare a homogeneous composition and state of aggregation of the mixture.

The device construction of the mixer

The building has a number of operations, which are based on a "wet" method of finishing. They use aqueous suspensions of finishing materials. To create the latest ready-dry compositions shut water and mix.

Algorithm preparing an aqueous solution:

1. In a pre-prepared dry mix tank is filled with water and shuts. Technology of preparation of the solution is indicated on the packaging.
2. A nozzle mounted on the power tool is performed stirring the mixture until uniform aggregation state. There is a break.
3. At the end of manufacturer recommended time the solution was again stirred with a mixer and then transferred to the work. The nozzle is washed by a mixture of residues.

Types of construction mixers

Mechanisms are classified according to the type of drive:

• RManual discharge mixerEquipped with a special nozzle. Used physical force man.
• Power tools - drill, hammer drill or a specialized device. It comes with different attachments.

The use of human power allows to process up to 1.5 kg of dry mix. Power tools different performance and economy of physical strength of the operator.

In layout units are divided into single-and twin-screw. Last characterized by high power and performance. Additionally, rotating in opposite directions, the nozzle position is stabilized mixer in one position.

The main technical indicators of the construction of the mixer - the ability for a one-off transaction mix concrete volume of the solution. It depends on the power tool.

Characteristics

Since the mixer is equipped with an electric motor, its power is measured in kilowatts. The higher the number, the greater the capacity of different tools:

• To solve the problems within the "home" repair manufactured home series. Power does not exceed 1 kW. In this category falls the majority of drills, hammers and small mixers.
• Specialists of construction and finishing work, need a tool with the power of more than 1 kW. The drill does not fall into this group because of their special characteristics.

Preparation of solutions - it is an additional tool functionality. It is suitable for short-term transactions associated with the preparation of mixtures.

• For processing large volumes (up to 20-200 liters per batch) mixer is intended building. Its design is designed to work with heavy and viscous mixture. The power tool of 2.5-3 kW.

The weight

Mass construction mixer varies between 2 kg (drill) 10-15 kg (Professional Series). A typical unit for solving domestic problems weighing 2-2.5 kg (drill or a hammer). Semi-professional tool - up to 7-10 kg.

functions

With stirring mixer produced or cooking liquid formulations or viscous suspensions:

• acrylic primers;
• paints based on organic solvents or water-based;
• bituminous mastics;
• Polymer fillers, gypsum or cement bases;
• sand-cement or gypsum plaster;
• adhesive compositions for ceramic tile and granite tiles, glass mosaic, natural or artificial stone;
• light and medium concrete with the composition of the binder, sand and gravel.

For the implementation of the basic operating functions of the instrument, there are a number of indicators:

speed control system

Built-in electronic mechanism automatically adjusts the engine speed. This is necessary to maintain a constant operation, which is broken during the stirring mixture.

When mixed with water the components chemically react. It appears complex composition with other physico-technical properties. One of them - viscosity - resists displacement when the particles relative to each other.

Other - weight of mix - requires an increase in power for moving of the solution.

These and other factors through the nozzle influence on the engine, and the speed begins to fall. Automatic controller does not allow this process to develop fully, maintaining optimal operation.

Thus the rotational speed stabilizer equipped professional model.

Torque indicator

Torque shows what internal forces occur in the solution when stirring. The index greater, the more dense and viscous mixture is capable of processing mixer.

stirring force it is directly related to the number of revolutions and maximum torque corresponding to the minimum rotation speed and vice versa.

Household series with output power up to 1 kW outputs 10-20 Nm. Such efforts sufficient to agitate the primers, paints and putties. From the intermittently can prepare plasters or tile adhesive.

If the manufacturer does not have the accompanying documentation data torque, it can be calculated independently by the formula:

M = (P * 30) / (n * 3,14), wherein

• M - torque in Nm;
• P - power of technical documentation in watts;
• n - number of revolutions / min.

Example:

Initial data:

• power 2000 watts;
• operations are carried out at 750 rev / min, then:

M = (2000 * 30) / (750 * 3,14) ≈ 25,5 Nm.

By reducing the speed to 500 units:

M = (2000 * 30) / (500 * 3,14) ≈ 38,2 Nm.

Speed

Building electric mixer discharged at the same speed, or is equipped with a two-speed gearbox. At rates of 750-850 / min is more convenient to work with liquid formulations.

They quickly mixed, the slurry thickens and does not separate. Values ​​less than 500 rev / min are used for the preparation of heavy and viscous solutions.

Single-speed models are available in light series with power up to 1 kW. Two-speed tool has a capacity of 1.2-1.5 kW. The first transfer mixer outputs to 650 rev / min, but this increases the torque.

The second speed is intended for mixing liquid lung compositions and mixtures.

Smooth start - operation, providing bezryvkovy engine start, a "soft" promotion. This avoids expansion dry components or spraying a liquid mixture of component solution.

Reduce peak loads. Increases tool life and ease of operation.

Electronic motor protection. Includes:

• automatic shutdown of the motor brushes when worn;
• interruption unit when overheated;
• stop operation under critical load conditions.

Hand Protection - it handles layout and equipping them with anti-vibration material. Ring option in the form of two clips is typical for household appliances.

Professional Series equipped with a T-shaped structure. Such convenient to handle when processing heavy mixtures.

Equipment

The structure of the mixer, except for the motor, housing and handle, and the device includes a nozzle for fixing it to the instrument.

nozzle attachment method

There are five basic ways to fix:

1. threaded. The nozzle is mounted on the spindle via a threaded connection. The most common for specialized tools. It is reliable, but it is inconvenient to use.

1. jaw chuck. Used as accessories for drills or drills mixers. Fixing removable devices in the holder by a special key.

1. SDS-compound. Common for perforating. It provides a secure fit, but requires a similar design in the nozzle. Suitable for work with putty, plaster, adhesive.

1. FastFix system. It is a keyless chuck. This type of lock is applied at the screwdriver. There is a drawback - when working with heavy mixtures quickly erased the edge of the corolla.

When using the reverse there is a risk unlocked (unwinding) of the tool in the chuck.

1. Morse taper. The surest way to mount attachment in a mixer. Distributed to professional tools. It allows you to work with all kinds of solutions.

The package, except for the tool include:

• accompanying documents - passport, the instruction manual, warranty card;
• set of dedicated keys;
• packaging.

accessories

In operation, the required safety equipment, supplies, accessories are:

• a removable electrical cable having a different length;
• safety glasses and gloves;
• container under a solution;
• replaceable nozzles.

Nozzle for the construction of the mixer

For mixing aqueous compositions and preparation of solutions are various types of stirrers:

• Propeller. The screw is designed as a three-bladed corolla. It resembles a ship's propeller or fan blades.

• crossing. The nozzle is equipped with a straight vertical blades made of rods of circular cross section. Creates a horizontal flow, whereby air hardly gets inside of the solution mixture and the components are not oxidized.

Used to work with heavy and viscous formulations.

• Spiral. Is right or left. The first solution moves upwards. It is used for adhesives, cement or gypsum-based and light and medium concretes. The second mixture is moving downwards.

Prevents spatter. Fillers and convenient for the slurry a mineral filler. Instrument equipped with a thrust reverser, is sufficient to have one of two nozzles.

By changing the direction of rotation of the screw, achieve solution flow changes direction. It applied in a mixer to the solution.

• Two-way screw. It is a combination of opposite screws. Lower picks up solution. Other changes the direction of flow is reversed.

This ensures the qualitative composition stirring. Used to work with liquid or inviscid compositions.

• universal screw. It combines the properties of the other nozzles. Suitable for processing liquid solutions, light and intermediate mixtures.

Given the weight of the stirrer itself (4-8 kg) and the forces arising during operation, the load on them, attributable to the person, can lead to fatigue. Such attachment is advisable to use a mixer for concrete.

device length of 400 or 600 mm. Extension rods are used when necessary. Dimensional step Ø: 80-100-120-140-160 mm.

To work with paint products preferably selected stainless steel. This will eliminate the risk of oxidation and introducing distortions in the color of the processed material.

The same steel should be used in the preparation of light and medium solutions containing mineral fillers. Recent by friction under stirring was washed topsheet.

Features

Ease of use and improved productivity helps additional equipment tools various options and additional functions.

For example, the drilling operation is added to the blender construction, enables vertical holes in soft materials. Useful in the construction or repair of wooden houses. The unit is sufficient to equip a corresponding cutting device.

options:

• Regulation of inrush current. Engine speed stabilizes at idle and immersed in the mixture and in the operating position during removal from the solution.

• Retainer rotation speed. On some models provide a mechanism for locking. It is an additional key that captures the selected speed.
• Rack. It is a metal structure that combines an electric mixer bowl mixtures and a support for them. Capacity is designed as a conical funnel with an opening at the bottom.

Such a scheme allows the device for preparing mixtures close to the object finishes.

• Additional handle. Tool home series (drill or a hammer) issued additional handle. It allows you to capture a second hand mixer that makes it easier to control when working with viscous fluids.

Benefits

Mixer - this is a highly specialized tool, the design of which is designed for the load arising in the preparation of mortars. When drilling operations occur mainly axial forces, because the drill is good for mixing liquid solutions.

Stronger puncher, but he can not afford a busy schedule with concrete structures.

Radical forces generated in operations training solutions, incorporated into the design of the construction of the mixer:

• possibility of working with solutions of volume of 100-200 liters;
• primary stirring duration does not exceed 10 minutes;
• composition solutions range from paints to aqueous compositions medium mix concrete with mineral fillers.

The introduction to the list of drilling operations function allows you to create a mobile machine to create vertical openings. This allows:

• carry through and blind holes in the tree;
• soil under drilling columnar or pile foundation;
• remove the ground under the support for a fence.

But for the last two operations required capacity of not less than 1.5 kW.

disadvantages

The main disadvantages are directly linked to the specifications of the unit, with an increase in power and performance increase:

• dimensions and weight;
• noise at work;
• cost.

Introduction drilling function partially affects the primary purpose of the mixer - preparing the mixtures. This is due to the fact that these two modes of operation are different:

• there are different loads;
• work carried out in other revolutions;
• Drilling function is required filing drill for drilling the go.

How to choose a construction mixer?

To select the tool in the first place need to determine the types, scope of work, the frequency of use of the unit. This affects the capacity and cost.

When repairing their own homes is sufficient drill or punch with a capacity of up to 700-800 watts. That's enough for cooking:

• plasters;
• putty;
• tiled adhesive;
• self-leveling floor;
• Mixing primers or paints and varnishes.

For heavy viscous mixture is better to stop the choice on the duplex unit with two-speed gearbox.

Building your own home - it's a drill mixer. Power 1000 Watts. The presence of the two-speed gearbox. Planting one nozzle. Cope with concrete solutions. Possible drilling of soil, wood drilling.

Import or domestic?

• At relatively the same characteristics of the Russian products are cheaper.
• Execution of comparable transactions - domestic production is almost not inferior to foreign analogues.
• Services. Repair network is better developed for the local technology, fewer problems with accessories and spare parts.
• Reliability, durability and quality. Alas, the imported "branded" tool on these indicators while ahead.

For the preparation of small amounts of mixtures, solutions household tasks advantageous to use domestic products. Private master suitable products with the trademark Fiolent, Interskol, Bison.

Professional teams with intensive exploitation of the instrument is best to opt for Bosch tool, Makita, Hitachi.

How to use the building mixer?

Building mixer must be used for its intended purpose, otherwise there is a risk of rapid release of his failure. Rules of operation of the tool and safety, see the accompanying documentation.

Before you start, regardless of the experience with a similar technique, you need to read the instruction manual and in the future guided by the recommendations contained therein.

A list of the main recommendations of the manufacturer:

• work only serviceable tool;
• before starting work make sure of serviceability of all components and accessories, check the oil in the gearbox;
• avoid constant peak loads;
• After finishing work or necessarily extended periods rinse water nozzle in the mixer, purging it of the accretions solution; the same requirement applies to the instrument as a whole;
• store the tool in a dry ventilated area.

Guarantee

The warranty period for the mixer is set by the manufacturer and indicated in the accompanying documentation. The operating instructions or other document required to be indicated by:

• rules of filling and the presence of the warranty card when applying for service activities;
• reception conditions tool for warranty repairs;
• the legal basis for the warranty conditions - the current Russian legislation, in particular, the Civil Code and the Law "On Protection of Consumers' Rights.

Warranty valid for the entire service life and extend to defects caused by production factors in output.

When buying goods in shops must be thoroughly acquainted with the delivery of complete, serviceability of the product and accuracy of documentation.

Malfunctions, repairs, spare parts

In case of failure of equipment during the warranty it is advisable to seek help from branded or accredited service centers.

At the end of the service time and with a good knowledge of the repair tool on its own is quite possible.

Most wear parts products:

• Commutator brushes;
• power button, switch, fixing, etc .;
• chuck;
• Head of the construction of the mixer.

Brushes, buttons, switches are available for service. In many models, the construction of power tools have direct access to the site, which houses the brush.

This makes it possible, without disassembling the entire body of the mixer, quickly replace the carbon brushes of the electric motor.

Buttons, switches, locks also have a quick connection to the main body, which makes them easy to dismantle and replace with new ones. These operations are described in the operating instructions or the data sheet.

If the damage of electrical parts, such as motor or electronic devices require service by service and repair service.

Tampering without relevant knowledge can lead to complete failure of individual nodes or tool as a whole.

A small mechanical damage is eliminated electrocable compound lived and damaged insulation recovery.

But it should be remembered that a large amperage may occur when starting or peak load, which strikes the junction of the repaired wire. For security reasons, better to put a new cable.

Easier to do it in the presence of a plug connection, it is enough to buy a new and connect the cord to the instrument. The absence of connectors require parsing housing, dismantle the damaged cable and attaching a new one.

Building mixer - it is an expensive tool. An attempt to repair the complex knots can lead to complete loss of the unit. Therefore it is better to lose time and spend the money on repairs in a specialized center.
