Rubber Granule Coarse Crusher
Introduction
The Rubber Granule Coarse Crusher is a heavy-duty pre-crushing machine designed to reduce large rubber materials into smaller, manageable granules. It is widely used in tire recycling lines to process waste tires, rubber blocks, and rubber scraps before fine grinding.
The machine adopts a robust rotor with durable blades to effectively tear and cut elastic rubber materials. After crushing, the rubber is reduced to a uniform size (typically 5–30 mm), which improves feeding efficiency and reduces the workload of downstream equipment such as grinders and pulverizers.
With its strong crushing capability, stable operation, and wear-resistant design, the coarse crusher can handle tough and flexible rubber without clogging. It also supports continuous operation, making it suitable for large-scale industrial recycling processes.
Overall, the Rubber Granule Coarse Crusher plays a key role in rubber recycling systems by improving processing efficiency, reducing energy consumption, and ensuring consistent material size for further processing.
Material Characteristic
The crushed rubber particles are generally in the form of irregular blocks or sheets, with a particle size ranging from 5 to 30 mm. The size is relatively uniform, but there are still some minor variations. Due to the elasticity of rubber itself, the particles remain relatively resilient, with rough surfaces, which is conducive to further crushing or grinding processing. At the same time, this type of material is relatively loosely packed and has good fluidity. In actual production, it is usually necessary to be combined with conveying and sorting equipment. Overall, the crushed rubber particles have already met the good processing conditions for reprocessing and are ideal intermediate materials for entering the fine crushing or grinding powder process.
