FAQ

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

Quick AnswerFor phosphate rock grinding, selecting a mill depends on the desired fineness and production rate. For medium-fine powders up to 400 mesh, vertical roller mills or Raymond mills are generally suitable due to their stable throughput, efficient classification, and energy-effective grinding

Quick AnswerProducing 5–10 tons per hour of calcite powder typically requires a medium-capacity industrial grinding system consisting of crushing equipment, feeding devices, a grinding mill, classification units, a dust collector, and powder conveying systems. When the target fineness is within 200

Quick AnswerThe most suitable mills for producing 300 mesh gypsum powder are the LM Vertical Roller Mill and the MTW Raymond Mill. Both can efficiently process gypsum with feed sizes up to 20 mm and achieve high output while maintaining consistent particle size distribution. Depending on production

Quick AnswerLimestone powder processing requires milling equipment chosen based on target fineness and production capacity. For powders ≤400 mesh, LM Vertical Roller Mills and MTW Raymond Mills are preferred due to their high throughput and stability. For ultrafine powders >400 mesh, LUM Ultrafi
