As a leading fine limestone grinding equipment manufacturer, Liming Heavy Industry Co., Ltd. offers a comprehensive range of grinding mills designed for high-efficiency limestone processing across various industries, including cement, power plant desulfurization, metallurgy, chemicals, and non-metallic mineral beneficiation. Our product portfolio—spanning from vertical roller mills and Raymond mills to European trapezium mills, micro powder mills, and ball mills—is engineered to deliver superior fineness, throughput, and energy savings. With a history dating back to 1987, 80,000 m² of R&D and manufacturing facilities in Zhengzhou’s High-Tech Zone, and an additional 67,000 m² workshop in Shangjie Industry Park, we combine modern scientific management, precision manufacturing, and continuous innovation to produce globally competitive grinding solutions. Whether processing limestone for desulfurization gypsum or preparing pulverized coal, our equipment is trusted by clients worldwide for durability, environmental compliance, and consistent performance.
Comprehensive Limestone Grinding Solutions
Liming Heavy Industry’s limestone grinding equipment is designed to handle a wide range of feed sizes (10–55 mm) and production capacities (0.5–400 T/H), ensuring flexibility for both small-scale operations and large industrial projects. Our technology integrates drying, grinding, powder selection, and conveying into a single system, reducing energy consumption and operational complexity. Key features include automatic electric control systems, pulse dust collectors for environmental compliance, and patented grinding mechanisms that extend wear part life. Below is a closer look at our primary limestone grinding machines:
- LM Vertical Roller Mill: Ideal for large-scale limestone grinding in cement and power plants, with capacity up to 400 T/H and feed sizes up to 55 mm. It uses a new milling device and automatic control for consistent product fineness.
- Raymond Mill: A classic choice for non-metallic minerals under Mohs hardness 7, suitable for calcium carbonate and gypsum processing, with output fineness from 613 μm to 44 μm and capacity of 1.2–4.5 T/H.
- MTW European Type Trapezium Mill: An upgrade of traditional Raymond and pendulum mills, offering higher productivity, lower energy consumption, and environmental protection. It handles feed sizes up to 50 mm and outputs 3–55 T/H for limestone desulfurization applications.
- MW Micro Powder Mill: For superfine limestone grinding, achieving fineness from 325 mesh to 3250 mesh (d97 ≤ 5 μm). Capacity ranges from 0.5 to 25 T/H, ideal for premium mineral powder markets.
- Ball Mill: A versatile grinding plant for ores and materials in beneficiation and construction, with capacities from 0.65 to 50 T/H and feed sizes ≤ 25 mm. It features a horizontal rotating barrel with steel balls for impact grinding.
Engineering Excellence and Quality Assurance
At Liming Heavy Industry, every grinding mill is the result of decades of scientific research, development, and field experience. Our strategy focuses on three pillars: scientific tackling of key problems, technological progress, and the integration of production, learning, and research. Our mature scientific research team continuously innovates to stay ahead of industry technological frontiers. For example, the MTW European Mill features a closed-loop air system with a pulse dust collector that meets stringent national environmental standards, while the MW Micro Powder Mill incorporates advanced Swedish grinding technology for ultra-fine outputs. All equipment undergoes rigorous testing for stability, productivity, and energy efficiency before shipment. With over 30 years of market presence, we have earned a reputation as a leader in both domestic and overseas machinery manufacturing, serving clients in limestone desulfurization, heavy calcium carbonate production, non-metallic mineral powder making, and beyond.

Frequently Asked Questions (FAQs)
- What is the typical fineness range for limestone ground using your equipment?
Our mills can produce limestone powder from coarse (613 μm, about 30 mesh) to superfine (5 μm, about 3250 mesh), depending on the machine model—Raymond mills are best for standard fineness, while micro powder mills achieve ultra-fine grades. - Can your limestone grinding mills handle wet or high-moisture materials?
Yes, especially the LM vertical mill and ball mill are designed with drying capabilities, allowing them to process moist limestone with humidity up to 6%% without clogging. - What industries commonly use your limestone grinding equipment?
Major applications include power plant flue gas desulfurization (limestone powder for gypsum production), cement manufacturing, steelmaking flux, paper and paint fillers, construction calcium carbonate, and agricultural lime. - How do you ensure environmental compliance during limestone grinding?
Our systems are equipped with pulse dust collectors and closed-loop air circulation to minimize dust emissions, meeting national and international environmental standards. No harmful gases are released during operation. - What is the typical lead time for a standard limestone grinding mill order?
Lead times vary based on configuration and capacity, but standard models like Raymond and ball mills can be shipped within 15–25 working days after order confirmation. Customized systems may require additional engineering time.
