Product Description

Dry Powder Double Screw Conical Mixing Machinery

Working principles:
Double screw conical mixer rotated around its axes by right of two internal asymmetric spirals which is installed on the cantilever. Mean while, the rotational force from the cantilever drive two spiral doing revolution around conical chamber axle wire.
Dry Powder Double screw conical mixer has 4 direction forces:
1.Two inner asymmetric spiral upgrade materials by rotation.
2.Tumbler low-speed rotation makes material circle motion.
3.Spiral rotation and revolution make materials absorbed while diffuse to circle direction.
4.Two flow materials upward then down to center, which come into being a downward material flow.

This way can full the bottom gap and form a convective circulation.

Flexible material selection
Material can be chosen from carbo 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.

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 used connection: direct connection, pulley connection, hydraulic coupler connection.

Powerful auxiliary components
Equipped with circulation medium jacket or steam coil jacket, the double screw conical mixer can realize the temperature control in mixing process.
In the mixer barrel, the part contact with material can coat some antiriot, anti-caking and metal isolation material according to different raw material. In some severe wear conditions, the screw plate can be overlaid by some wearing proof alloy.
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.

Excellent discharging unit
Spherical valve or plum-blossom dislocation valve is matched to the double screw conical mixer.The raised Sphere match the track of the bottom of screw, to reduce the mixing dead zone to the maximum, to make the largest discharging area, and make sure no leftover. Spherical valve has excellent sealing effect to powder, liquid and even in the negative pressure state.Plum-blossom dislocation valve is easy to operate, control the discharging speed and be combined with the bottom supporting device of the longer screw.

Selection way:
1. Choose the batch working volume 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 chosen from 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.
