Q: Which type of toothed roll crusher is commonly used for crushing brittle coal?

A: The most commonly used toothed roll crusher for crushing brittle coal is the double toothed roll crusher (also known as the 2PGC crusher).

The double toothed roll crusher is a dual-roll type with coarse and fine toothed roll surfaces. It operates via two independently driven rollers rotating in opposite directions, using compressive and shearing forces to crush materials. Toothed rolls are well-suited for coarse and medium crushing of brittle and soft materials.

Double Toothed Roll Coal Crusher

Why is the double toothed roll crusher suitable for brittle coal?

1. Excellent material compatibility: Double toothed roll crushers are designed for brittle materials with medium hardness or below—a category that includes various types of coal such as bituminous coal, anthracite, and lignite.
2. Wide range of applications: This equipment is widely used across industries including coal, metallurgy, mining, chemicals, and building materials. It is particularly effective for crushing raw coal (including gangue) in large coal mines or coal preparation plants.
3. Superior crushing performance: Double toothed roll crushers offer a high reduction ratio, low over-crushing rate, and uniform product particle size.
