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.driven unit
The driven unit, power and output speed are varied according to different raw material, starting method, and processing.
Options for motor: general motors, explosion-proof motors, variable frequency motor, high efficiency and energy saving motor.
Commonly used reducers: R-series, K-series, and F-series gear box; cycloidal reducer, universal gear reducer, planetary gear reducer. Commonly motor-gearbox connection: direct connection, pulley connection, hydraulic coupler connection.

3.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, or agglomerated material breaking and mixing, and cooling or heating.
The main shaft agitator could be: inner and outer ribbon, paddle and ribbon, disconnected ribbon, and shaver-shaped agitator.

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 colleting 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.
