Plough Mixer
Introduction
Plough Mixer is a high speed mixer with high homogeneity. During the mixing process, the raw materials are transferred around the drum in a radial, lateral and longitudinal movement by the high speed plough shears and choppers. Moreover, the mixing time is short, especially for free flowing powders or granules. Liquid additive and Heating or Cooling is also applicable.
Working Principle:
In the first case the mixing shaft and the tools are horizontally installed, thus achieving, at corresponding movement, a product reaching from a loose product bed up to a mechanically generated fluidised bed. In the second case the mixing shaft is installed in vertical direction, whereby a socalled vortex is built at corresponding movement. The installation of fast-rotating chopper heads enables the mixing of products tending to lump formation. Due to the mixing tools, the material to be mixed is hereby specifically fed to the activity area of the chopper head. Besides the conventional ploughshare mixing tools a large variety of modified mixing tools is available, facilitating an optimum adaptation of the mixing tools to the individual material.
Product introduction
1.Flexible material selection
Material can be carbon steel, manganese steel, ss304, 316L and 321; besides, different material can also be used 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.Reliable 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.High efficiency mixing unit
The plow heads in the plough shear mixer can be dismountable, which is convenient for replacement. Wear-resistance treatment is done on the plow, making the plow more durable to the severe wear conditions. Different main shaft agitators can be equipped according to the properties of raw materials.
Main shaft agitators: ordinary plough, saw-toothed plough, and shaver-shaped paddle; High speed chopper: multiple-piece cross blade, double-piece lotus blade.
4.Excellent discharging unit
Standard valve for horizontal plough shear 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 option: powder spherical valve, cylinder valve, plum-blossom dislocation valve, butterfly valve, rotary valve etc.
5.Powerful auxiliary components
Mixer is 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.
