The PG double-toothed roller crusher is a mechanical device used to crush brittle materials of medium to low hardness. It is primarily used in coal, mining, metallurgy, sand and gravel yards, and coal preparation plants. Its core function is to split and crush the material through shear force generated by the counter-rotating twin-toothed rollers. It features a high crushing ratio, uniform particle size, and low over-crushing.

Operating Principle

The double-toothed roller crusher utilizes two counter-rotating rollers to crush the material. The drive mechanism is driven by two electric motors via a V-belt, which transmits power to a shear pulley, pulling the rollers in opposite directions. During crushing, the material passes through the rollers from the feed inlet, where it is crushed and discharged from the bottom of the base frame.

Advantages of the new double-toothed roller crusher:

• Compact structure and small size: The spiral tooth arrangement allows for easy screening and sorting of the material.
• Low energy consumption: The crushing teeth are designed with shear force in mind in their shape and size.
• The crushing teeth are wear-resistant, with a typical service life of 6-10 months.
• Non-clogging: During operation, material can be poured into the entire upper portion of the crusher frame, making the receiving port less susceptible to clogging. The discharge port is also large, allowing almost the entire lower portion of the machine to discharge the crushed product.
• Adjustable product size: minimal over-fine or powdery product, no oversized particles, and no oversized particles.
• Low operating costs and easy maintenance.
