Roller crushers are designed for crushing both wet and dry laboratory samples with hardness less than 6 in Mohs scale. We offer crushers with two or four rolls. Both types of crushers are available in versions with regulated gap between rollers (type R) to allow changing final grain size.

Typical crushed materials are: construction materials, coal, ores, minerals, glass, soil.

Roller crushers are mostly used in sampling systems for loose materials.

  • Roller crushers are designed for crushing both wet and dry laboratory samples with hardness less than 6 in the Mohs scale.

  • The sample is crushed between two rotating steel rollers. Run-through crushing.

    • possible manual or fluent (using electric geared motor) adjustment of roller gap
    • step regulation of roller gap
    • grinding elements hardness: 50HRC
  • coal, ores, minerals, slag, glass, sinters, fluxes, soils, seeds, clinker, fertilizers, ashes, dusts, residues, coke, dolomite
