The double roller crusher (twin-roller crusher) crushes material by clamping it between two counter-rotating parallel rollers. Roller speed, tooth structure and the gap between the rollers can be adjusted to the material characteristics, giving a narrow and repeatable particle size distribution.

Key Features

Roller gap adjustable between 75 µm and 1 mm — narrow particle size distribution
Four roller materials available: alumina, high manganese steel, zirconia, tungsten carbide
Controlled crushing through compression, shearing and friction forces
Nylon scraper keeps the roller surface clean and prevents clogging
Quiet belt-driven operation, 220 V supply
Compact housing — suitable for the laboratory bench
