Applications:

Fine Rubber Powder Production Line: Produces 40-120 mesh fine rubber powder for use in plastic running tracks.

Pre-treatment for reclaimed rubber production:: Grinding rubber blocks to a fineness suitable for desulfurization processes.

Preparation of modified rubber materials: Providing high-quality raw materials for rubber asphalt and rubber-plastic composites.

Performance Advantages

Precision grinding, controllable particle size

The gap between the two rollers can be precisely adjusted within the range of 0.1-5mm, ensuring uniform and stable output particle size.

Efficient cooling, quality assurance

An innovative internal circulating water cooling system prevents rubber from aging and deteriorating due to high temperatures, maintaining the physicochemical properties of the rubber powder.

Dual drive, powerful performance

Equipped with an independent dual-motor drive system, each roller is directly driven by a high-power motor through a hardened gear reducer, resulting in high torque and high transmission efficiency.

Wear-resistant roller surface, long service life

The roller surface is made of special alloy chilled cast iron, with wear resistance 3-5 times that of ordinary materials, significantly extending maintenance cycles.

Intelligent control, easy operation

An integrated PLC control system with overload automatic protection and fault alarm functions allows for one-person operation of multiple machines.

Working Principle

Differential Shearing: The two rollers rotate relative to each other at different speeds (speed ratio 1:1.2-1:1.5), subjecting the material to intense shearing, compression, and tearing forces between the rollers.

Particle Size Control: The output particle size is precisely controlled by adjusting the gap between the two rollers to achieve the required fineness of the rubber powder.

Circulating Grinding: Coarse material is returned for re-grinding through an internal circulation system, ensuring a first-pass yield of over 85%.
