Liming Heavy Industry presents a comprehensive range of high-performance calcite grinding machines, backed by a robust one-year warranty and lifetime technical support commitment. Our engineered solutions, including the LM Vertical Roller Mill, Raymond Mill, MTW European Type Grinding Mill, MW Micro Powder Mill, and Ball Mill, are designed to transform raw calcite into precise, high-value powders for diverse industrial applications. With over three decades of expertise in manufacturing crushing and grinding equipment, we ensure each machine delivers optimal efficiency, reliability, and environmental compliance, supported by our global service network and dedication to continuous innovation.
Founded in 1987, Liming Heavy Industry Co., Ltd. has established itself as a leader in the design and production of large and medium-sized mineral processing machinery. Our corporate philosophy integrates intensive research, precision manufacturing, and customer-centric sales, operating from expansive facilities in Zhengzhou's HI-TECH Industry Development Zone and Shangjie Industry Park. This foundation enables us to develop grinding technologies that meet the exacting demands of modern industries, particularly in the processing of non-metallic minerals like calcite.
Calcite, a critical mineral in sectors ranging from construction to chemicals, requires grinding equipment capable of achieving specific fineness levels while maintaining operational economy. Our LM Vertical Roller Mill stands out for integrated processing, combining drying, grinding, powder selection, and conveying into a single, streamlined system. Ideal for medium to large-scale operations requiring capacities up to 400 T/H, it excels in producing consistent calcite powders with excellent particle size distribution, significantly reducing energy consumption per ton of output.
For fine to ultra-fine grinding applications, the Raymond Mill and its advanced evolution, the MTW European Type Trapezium Mill, offer proven reliability. The Raymond Mill handles materials under 7 Mohs hardness, producing fineness between 613μm and 44μm, making it a versatile choice for standard calcite powder production. The MTW Mill incorporates patented technological upgrades, featuring a more efficient grinding chamber geometry and an advanced separator system. Its closed-circuit design with a pulse dust collector ensures minimal dust emission, aligning with stringent environmental standards while delivering capacities from 3 to 55 TPH.
When the application demands superfine calcite powder, our MW Micro Powder Mill is the engineered solution. Utilizing advanced Swedish grinding technology, it achieves fineness levels up to d97 ≤ 5μm (3250 mesh), with adjustable output to suit specific product requirements. Its unique grinding mechanism, where dozens of rollers rotate against a stationary ring, ensures uniform particle size and high throughput for specialized markets such as high-grade plastics, paints, and coatings. The system's integrated pulse precipitator guarantees a clean, environmentally friendly operation.
The classic Ball Mill remains a cornerstone for many grinding circuits, especially where versatility is paramount. Capable of grinding calcite and a wide array of other materials, its simple, robust design ensures long service life with minimal maintenance. The cascading action of steel balls within the rotating chamber provides effective impact and attrition grinding, suitable for both wet and dry processes. It is often the machine of choice for projects requiring a flexible, all-purpose grinding solution.
Beyond the machinery itself, our commitment to customer success is embodied in our one-year comprehensive warranty and lifetime support promise. The warranty covers all manufacturing defects and component failures under normal operation, providing peace of mind from day one. Our lifetime support extends far beyond the warranty period, encompassing technical consultation, spare parts supply, process optimization advice, and on-site service assistance. This enduring partnership is facilitated by our mature scientific research team and global service network, ensuring your grinding investment remains productive for its entire operational life.
Every Liming grinding machine is the product of a "production, learning, and research" development model. We persistently tackle key technological challenges to enhance product competitiveness, aiming at the industry's technological frontier. This results in machines that not only meet today's productivity goals but are also engineered for future demands, with features promoting energy savings, reduced wear, and easier maintenance. Choosing a Liming calcite grinder means investing in a system backed by over 30 years of innovation, precision manufacturing, and an unwavering commitment to supporting your operational excellence.
