FAQ

An efficient limestone grinding plant starts with matching the process to the product target. For 80 to 325 mesh powder, MTW Raymond Mill or LM Vertical Roller Mill is usually selected based on capacity and drying demand. For powder finer than 400 mesh, LUM Ultrafine Vertical Mill or MW Micro Powder

For 200 mesh quicklime powder, the standard industrial choices are MTW European Type Raymond Mill or LM Vertical Roller Mill, selected by required capacity, feed size, and drying demand. Because 200 mesh is within the normal range for both machines, the decision is usually based on throughput, moist

Quick AnswerTo grind calcite into 800 mesh fine powder, the practical choice is an ultrafine grinding system with high-efficiency classification. In most industrial lines, 800 mesh means about D97 15 microns, which is beyond the stable operating range of standard Raymond or conventional vertical rol

Which mill is normally selected?For limestone at 20 tons per hour, mill selection mainly depends on target fineness and moisture. Limestone is relatively soft, usually Mohs 3 to 4, so impact, compression, and grinding under roller pressure all work well. If the product is in the 80 to 325 mesh range

Material Behavior and System FeedLimestone, primarily calcium carbonate, exhibits a Mohs hardness of 3.0 and low abrasiveness. This makes it highly grindable. Before entering the milling circuit, the raw material feed size must be crushed to under 35mm. Feed moisture should remain below 6% to preven

Understanding Barite Material BehaviorBarite (barium sulfate) has a high specific gravity of 4.2 to 4.5 and a Mohs hardness of 3.0 to 3.5. Because it is highly brittle and possesses low abrasiveness, the material is highly grindable. However, its high density requires a robust sweeping airflow withi

Quick AnswerFor quicklime (CaO) powder production, the most suitable grinding mills are closed-circuit vertical roller mills and modern Raymond-type mills. For fineness up to 400 mesh and capacities from about 5 to 100 t/h, LM Vertical Roller Mills and MTW Raymond Mills from Liming Heavy Industry ar

Quick AnswerFine marble powder for artificial stone is typically produced in the 400–1500 mesh range using closed-circuit grinding systems with high-efficiency classifiers. For capacities above about 3 t/h, the most suitable mills are LUM Ultrafine Vertical Mills and MTW Raymond Mills from Liming H

Quick AnswerThe best grinding solution for limestone powder production depends mainly on required fineness and plant capacity. For 80–400 mesh products used in building materials, desulfurization, and general fillers, the most suitable solutions are LM Vertical Roller Mills and MTW Raymond Mills fr

Quick AnswerTo produce 400 mesh barite powder for oil drilling, you need to start from clean, dense barite ore, crush it to below 20–25 mm, then grind it in a closed-circuit system with efficient classification. For continuous industrial production, vertical roller mills (LM series) or modern Raymo

Quick AnswerFor producing calcite powder suitable for paints, the ideal equipment depends on required fineness and production rate. For medium-fine powders up to 400 mesh, LM Vertical Roller Mills or MTW Raymond Mills are recommended due to their high throughput and integrated classification. For ul

Quick AnswerTo achieve a stable 15 TPH output of 200 mesh calcite powder, the MTW175 European Type Raymond Mill is the optimal engineering choice. This setup balances energy efficiency with precise particle size control. The system should include a primary jaw crusher, a high-efficiency centrifugal
