The Shuliy RPM Series Rubber Powder Making Machine is designed to convert pre-processed tire blocks into graded rubber powder for recycling applications. It is a key fine-processing unit in a waste tire recycling plant, combining rubber crushing, screening, steel wire separation, and nylon fiber removal.

The machine handles tire blocks measuring 30–100 mm and produces rubber powder from 5 to 40 mesh. Depending on the selected model and finished powder size, available capacity ranges from 80 kg/h to 2,300 kg/h.

Shuliy Machinery has supplied tire recycling equipment to customers in Australia, Mexico, Colombia, Spain, and other international markets. This machine can be supplied as a stand-alone rubber processing unit or integrated into a complete tire recycling line.

Main Components and Design Features

The rubber cracker mill machine structure includes a motor, reducer, crushing rollers, machine base, cooling system, lubrication system, gear protection covers, and supporting separation equipment.

Grooved Alloy Rollers

The supplied machine information shows dual grooved rollers made from 5Cr6MnMo alloy material. The roller speed ratio is 1:2.5, which creates a shearing effect during crushing. The grooved surface helps grip and convey rubber blocks through the processing area.

Cooling and Lubrication Systems

Rubber grinding generates heat through friction and continuous material processing. The cooling system helps manage operating temperature, while the lubrication system supports normal operation of bearings and transmission components.

Protective Covers

Gear and transmission covers help reduce access to rotating components during operation. Final guarding, electrical configuration, and safety equipment should be confirmed according to local regulations and the final plant layout.

Mesh size reference:

  • 10 mesh: approximately 2.5 mm
  • 20 mesh: approximately 1.25 mm
  • 30 mesh: approximately 0.83 mm
  • 40 mesh: approximately 0.63 mm

The listed capacity is based on the finished powder size. Actual output may vary according to tire type, rubber composition, input size, steel and fiber content, screen condition, and operating parameters.

If You Want to Build a Complete Tire Recycling Line

The Rubber Powder Making Machine can work with other Shuliy tire recycling equipment to form a complete production line. The exact configuration depends on tire size, input condition, capacity requirement, and final product specification.

A typical passenger and truck tire recycling process may include:

Semi-autometic line: Tire sidewall cutter– tire strip cutter– tire block cutter– bead wire remover– rubber powder maker–fiber seperator

Fully automatic line: Tire debeader– Tire cutting machine– rubber shredder– rubber powder machine

An OTR tire recycling plant may need:

OTR tire steel debeader– OTR Tire Cutter– Tire shredder– Rubber powder maker

Shuliy Machinery can recommend a complete configuration based on your raw material, required output size, processing capacity, plant space, power supply, and end-product application.
