1.material selection
Material can be carbon steel, manganese steel, ss304, 316L and 321; besides, different material can also be used in combination.
Material is different between the part contact with the raw material and the parts don’t contact with the raw material.
Surface treatment for stainless steel include sandblasting, wiredrawing, polishing, mirror polishing, all can be used in different parts of a mixer.
2.mixing unit
Different main shaft agitators can be equipped according to the properties of raw materials.
Materials commonly mixed are: different kinds of powder to be mixed with each other, batches mixing for the same material, powder with a small quantity of liquid, liquid with some powder, like slurry, thickening or diluting slurry, granule with powder, granule with granule, agglomerated material breaking and mixing, and cooling or heating.
The main shaft agitator could be: inner and outer paddle, paddle and ribbon, and shaver-shaped agitator.
3.efficient agitator
The paddle mixer has flat paddle and scraper paddle,and is widely used in granule material especially fluffy or elastic material! the paddle has its own angle, matching the running shaft to mix material! the structure of the paddles is simple, which can add wear proof PTFE at the surface or coat with some coating like alloy or PTFE .
4.discharging unit
Standard valve for horizontal mixer is pneumatic planar flap valve. When close the valve, the planar flap match the mixing barrel perfectly, this makes no mixing dead zone and better mixing effect.
The drive types of valve are Manual, pneumatic, and electric.
Valves for consideration: powder spherical valve, cylinder valve, plum-blossom dislocation valve, butterfly valve, rotary valve etc.
5.inlets
Various inlets on the top cover of the barrel can be designed according to different situations.
They can be used as man hole, cleaning door, feeding hole, vent, and dust collecting hole. The top cover can be designed as fully-opened lid for easy cleaning.
6.auxiliary components
Mixer is frequently equipped with many auxiliary components, like steam coil jacket, honeycomb pressure jacket, medium circulation jacket, sampling valve, high speed chopper, temperature sensor, weighing system, dust removal system and so on.
Different heat medium requires different jacket, it can be used for heating and cooling, while, the temperature should be within 250 Celsius degree.
If a small quantity of liquid is required during mixing, spraying or atomizing unit is necessary in order to mix the liquid evenly with the main ingredient. The liquid-adding system is basically composed by the three parts: pressure source, liquid storage pot and spraying nozzles.
Horizontal single-shaft paddle mixer is composed of a power group driven the shaft to rotate, several paddles with certain angles distribute in the shaft continuously, turning over the material in the operation, making the material moving in all direction. and the small resistance the agitator creates won't crash the material so as to operate smoothly.
Selection way:
1. Choose the batch working capacity from 0.1cbm to 20cbm, select mixer accordingly.
2. Choose raw material for the part contact with raw material, non-contact with raw material, other parts like motor and reducer, bearing material can not be chosen; According to the material to be mixed, processing condition, health level, raw material can be mild steel, sus304, sus316L, sus321; And choose the surface treatment according to the raw material.
3. Motor power is chosen according to the material gravity, fluidity, and operation.
Operation is divided as: Start mixer when it is empty (normal duty); Start mixer with load (heavy duty)
4. Adding the auxiliary components like spraying, heating and cooling according to processing condition.
5. Mixer inlets: feeding ports, cleaning port, vent.
6. Chose discharging and driven mode: manual, pneumatic and electric.
Note: mixer selection is a very important step, your detailed material information, processing and factory arrangement is very helpful to get professional technical support from us.
