There are mainly two types of crushers used to crush limestone, jaw type crusehrs or impact type crushers. Crushing is done either in two stages or in a single stage. In the two stage crushing system, a jaw crusher is used in the first stage for raw crushing, followed by impactcrusher in the second stage. In single stage crushing, an impact type crusher is used. We will offer the suitable crusher according to your needs.

After crushing, the size of limestone is suitable for finish-grinding. The feed materials is fed pneumatically through a venturieductor into the vertical roller mill. The particles are pulverized by a high speed agitated grinding media. The grinding media can be stainless steel, chrome steel, alumina or zirconia. The micronized particles are entrained in the air stream and exit the mill in a high efficiency air classifier. The on size particles are separated and the oversize returned to the vertical roller mill for regrinding. In addition, this grinding process is suitable for limestone,calcium carbonate, marble and grinding down to 1 micron average particle size.
