Limestone mill grinds limestone into powder, limestone powder has different specifications: It can be used to produce anhydrous calcium chloride which is the main auxiliary raw material of sodium dichromate production. It is the main raw material of …
with the limestone slurry product, continuously recycled inside an absorbing tower. Process description of wet grinding & dewatering Gross limestone from a day silo is fed to the ball mill at a con - trolled rate by a weigh feeder. WFGD reclaim water or process water from the WFGD system is used to produce the lime - stone slurry.
2. GENERAL DESRIPTION OF LIMESTONE GRINDING SYSTEMS (LGS) The purpose of this system is to grind lump limestone of Size 25 mm (Max) to powder and for preparation of limestone slurry. The duct from the limestone silo hopper feeds the limestone to the gravimetric feeder. The Gravimetric feeder feeds limestone to Wet ball mill system.
Limestone Grinding and Mixing System Ground limestone is typically used for the same purpose as hydrated lime in the control of pH. Whilst limestone slurry is not as effective as MOL, it is an economical option where quicklime is not cost effective or readily available.
Wet ultra-fine grinding of a limestone powder (< 100 μm) has been investigated in a stirred media mill with respect to the effect of slurry rheology.The grinding results obtained by various parameters (i.e., molecular weight of a dispersant, solids concentration, additive dosage, addition method and beads load) are evaluated in terms of energy efficiency and the fineness of a product.
