The rubber crusher machine, also known as a rubber cracking mill, rubber grinder, or rubber grinding machine, is key size-reduction equipment used to crush and grind waste tire rubber chips into 5–40 mesh crumb rubber or coarse rubber powder.
As the core grinding stage in a complete tire recycling plant, it processes pre-shredded rubber granules into smaller, more uniform particles with stable output size and improved material quality.
After the waste tire shredder machine reduces whole tires into rubber chips, the rubber cracking mill further grinds the material into crumb rubber for rubber powder processing, reclaimed rubber, rubber tiles, rubber mats, and modified asphalt applications.
This rubber crusher is also called a rubber cracker mill in some markets, especially for crumb rubber and recycled rubber processing applications.
A rubber crusher machine is a heavy-duty rubber grinding machine used in tire recycling systems to reduce pre-shredded rubber chips or rubber granules into smaller particles. It is also commonly referred to as a rubber cracking mill, rubber cracker mill, rubber grinder, rubber grinding machine, tire grinding machine, or crumb rubber machine.
Unlike rubber mixing mills, which are mainly used for compounding rubber, a rubber cracking mill is specifically designed for size reduction and material processing in recycling applications. It provides strong grinding force, adjustable output size, and stable continuous operation for crumb rubber and coarse rubber powder production.
The rubber crusher machine provides stable rubber grinding performance and produces uniform 5–40 mesh crumb rubber or coarse rubber powder with consistent particle size.
Designed for long-term recycling production, the rubber cracking mill supports continuous operation with stable output and efficient size reduction.
This rubber cracker mill uses wear-resistant chilled cast iron rollers and a strong machine frame, helping improve service life under industrial tire recycling conditions.
The roller gap can be adjusted to control rubber powder fineness, making the machine suitable for different crumb rubber and recycled rubber applications.
The optimized rubber grinding machine structure helps reduce energy usage while maintaining stable output and reliable grinding performance.
We provide different models of rubber crusher machines and rubber cracking mills from the XKP series to meet various capacity and output size requirements. Whether you need a standalone rubber grinder, a rubber grinding machine, or integration into an existing recycling system, our engineers can recommend a suitable configuration based on your raw material, capacity, and final rubber size.
Waste tire shredder machine → Rasper machine → Granulator → Rubber crusher machine / Rubber cracking mill → Screening system → Magnetic separation → Fiber separation
In a complete rubber powder production line, the rubber cracking mill works as the core grinding unit for producing stable 5–40 mesh crumb rubber or coarse rubber powder.
We provide customized solutions based on tire type, feeding size, capacity, automation level, and final output requirements.

The typical output size of a rubber crusher machine or rubber cracking mill is 5–40 mesh crumb rubber or coarse rubber powder. The final size depends on feeding size, roller gap, screening system, and production requirements.
Yes. A rubber cracking mill can produce 5–40 mesh rubber powder. If finer output such as 30–120 mesh is required, it can be combined with a fine grinding system for further rubber powder processing.
Yes. In many tire recycling projects, a rubber cracking mill is also called a rubber crusher, rubber crusher machine, rubber grinder, rubber grinding machine, or rubber cracker mill.
The model selection depends on required capacity, feeding size, output mesh, motor power, and whether the machine will be used as a standalone rubber grinder or integrated into a complete tire recycling system.
The price of a rubber crusher machine depends on roller size, motor power, processing capacity, output mesh, and whether it is used as a standalone machine or integrated into a complete tire recycling system.
