The toothed roller crusher, also known as the double-toothed roller crusher, is named for its main crushing components consisting of two toothed rollers, primarily used for crushing ores. The toothed roller crusher features safety and reliability, high efficiency with low consumption, uniform particle size output, and easy maintenance. It ensures uniform particle size of the crushed material with a low over-crushing rate, capable of medium and fine crushing of medium-hard and soft ores. The toothed roller crusher is suitable for industries such as coal, metallurgy, mining, chemical, and building materials, and is particularly well-suited for crushing raw coal (including gangue) in large coal mines or coal preparation plants.

The double-toothed roller crusher mainly consists of the roller assembly, roller support bearings, pressing and adjustment devices, and the driving device.
