Material Properties and Grinding RequirementsCalcium carbonate (CaCO₃) has a Mohs hardness of around 3, with brittle fracture behavior, making it suitable for grinding by compression and shear. Feed size is typically below 20–30 mm after crushing. Moisture should be controlled under 3% to avoid ag

Dolomite Properties and Grinding BehaviorDolomite has a Mohs hardness of 3.5–4, slightly harder than limestone but still brittle and suitable for compression grinding. It breaks efficiently under roller pressure with low energy loss. Typical feed size is below 30–40 mm after crushing, and moisture

Abstract: As India moves toward a more sustainable agricultural paradigm, the role of quicklime (calcium oxide) in soil conditioning has become paramount. Acidic soils across regions like Kerala, Assam, and the Western Ghats significantly hinder crop yields; however, the effectiveness of lime depend

Partnering for a Nickel-Powered FutureAt the beginning of the new year, encouraging news arrived from Sulawesi, Indonesia, a key hub along the Maritime Silk Road. On January 6, 2026, the Phase II Zhongqing New Energy Project at CNGR's Morowali Industrial Base—equipped with core systems and equi

Material Characteristics and Grinding BehaviorLimestone typically has a Mohs hardness of 3–4, making it a soft to medium-hard, brittle material. It fractures easily under compressive and shear forces, which favors roller-based grinding systems. Feed size is usually below 30–50 mm after primary cru

Why is limestone relatively easy to grind?Limestone is a soft to medium-soft material, usually around Mohs 3, with good brittleness and low abrasiveness. That means the grinding load is moderate and wear on rollers, rings, and liners is normally lower than with silica-rich stone. In most plants, cru

We are pleased to announce that Liming Heavy Industry will participate in the 139th Canton Fair.📍 Booth: Hall 20.1, J44📅 Date: April 15–19, 2026📌 Venue: China Import and Export Fair Complex, Guangzhou, ChinaWe sincerely invite you to visit our booth and explore our latest grinding and cement

Why is a Raymond mill usually the best fit at 6 TPH?At 6 TPH, barite grinding is in the middle range where stable fineness and simple operation matter more than very large installed power. Barite is brittle, with typical Mohs hardness of 3 to 3.5, so it breaks well under roller and ring compression.

What makes barite suitable for drilling powder production?Barite is mainly used in drilling mud as a weighting agent, so the mill choice must support stable fineness, low contamination, and steady throughput. The mineral is relatively brittle, with typical Mohs hardness around 3 to 3.5. It is not di

What makes quicklime difficult to grind?Quicklime, or CaO, is brittle and usually around Mohs 3 to 4, so breakage itself is not the main problem. The real issue is moisture. Quicklime reacts with water and absorbs humidity from air, which can cause hydration, agglomeration, and heavy buildup in duct

Why is an ultra-fine mill preferred for 800 mesh calcite?Calcite is a relatively soft mineral, usually around Mohs 3, with good brittleness and low abrasiveness. That makes it easy to grind, but 800 mesh is already in the fine powder range, so the key issue is not breakage alone. The real requiremen
