Product Description

A tub grinder is widely used in the forestry and recycling industries to grind various organic materials, such as wood, brush, and agricultural residue, into smaller particles. By reducing the sizes of these materials, tub grinders can turn them into valuable and salable products, such as mulch, boiler fuel, and compost, just to name a few. In addition, tub grinders can also be employed to decrease the volume of these materials, thus reducing transportation requirements and saving costs on dumping.
Tub grinders were originally designed for green waste recycling, turning the waste wood into boiler fuel. Later, tub grinders were used in landfills to reduce green waste. Besides, in composting operations, tub grinders help create mulch that is a carbon source. Nowadays, with the development of landscape mulch, tub grinders are popular in this industry.
Tub grinders in various sizes are available, equipped with different horsepower. They can deal with a variety of green waste, including debris piles, logs, stumps, leaves, and C&D materials.

Product Details

Working Principle Of Tub Grinder
During operation, the tub grinder’s motor drives the rotor to rotate at high speed. Simultaneously, the feed hopper undergoes slow rotation under the motor’s influence. Materials are introduced into the hopper, where internal paddles evenly distribute them onto the rotor. The high-speed rotation of the rotor causes the materials to undergo preliminary crushing through the cutting and tearing action of the blades. Subsequently, the processed materials that meet specifications fall onto the screen mesh within the crushing chamber under the combined effect of gravity and rotor impact. Those materials meeting requirements are discharged through the screen mesh, while those not meeting specifications undergo secondary or even tertiary crushing within the chamber until they meet the desired criteria.
