Selection of horizontal screw belt mixer for industrial powder material mixing

The recommended choice for industrial powder material mixing is the horizontal screw belt mixer. This equipment achieves efficient convective mixing with a double-layer reverse screw belt structure, making it particularly suitable for uniform mixing of powders and trace liquids. It has the advantages of fast mixing speed, low residual rate, and high loading coefficient. For industrial powder scenarios, its gentle mixing process can effectively reduce material breakage and ensure product integrity.

Working principle of horizontal screw belt mixer

Bidirectional convective mixing mechanism

There are two layers of spiral belts with opposite rotation directions inside and outside the equipment:

The outer spiral straps gather the material from both sides of the cylinder towards the center

The inner spiral belt pushes the material from the center to both sides

Forming strong axial and radial convection circulation, high uniformity mixing can be achieved in a short period of time.

Low shear, high uniformity design

The gap between the screw belt and the cylinder wall is controllable (usually 3-5mm), running smoothly, with minimal damage to powder particles, especially suitable for fragile or high value-added powders (such as metal powder, food additives).

U-shaped cylinder body+fully open discharge port

U-shaped structure reduces dead corners and ensures clean unloading

Optional pneumatic large door discharge device, residual amount can be controlled below 0.1%

Scope of Application

Divided by material type

Powdered materials: such as putty powder, dry mortar, PVC powder, dyes, pigments, metal powders, etcGranular materials: such as compound fertilizer particles, feed particles, plastic particles, etc

Viscous materials: such as real stone paint, putty paste, mixture of adhesive liquid and powder (solid slurry mixture)

Materials with high uniformity requirements: such as positive and negative electrode materials for lithium batteries, with a mixing accuracy of up to 3/100000 standard deviation

Divided by mixed form

Solid solid mixing: efficient homogenization of powders, such as mixing ratios of food additives

Solid liquid mixing: Adding a small amount of liquid (such as water, resin, grease) to the powder to achieve wetting and dispersion, as in the PVC dry mixing process

Paste like material mixing: can handle viscous or cohesive materials, such as pharmaceutical excipients, cosmetic base materials, etc
