Marble consists primarily of calcium carbonate, making it an excellent raw material for producing heavy calcium carbonate. It is widely used in the plastics, rubber, coatings, papermaking, and engineered stone industries, where the whiteness, fineness, and particle size distribution of the powder directly determine product quality. If large quantities of marble scrap can be ground and reused, it can significantly increase revenue and reduce solid waste.
Addressing the grinding properties and whiteness requirements of marble, Shanghai Shibang offers a full range of equipment, including the MTW European mill, LM vertical mill, MTW6X intelligent mill, PMD permanent magnet direct-drive mill, and LUM ultra-fine mill, to achieve efficient, environmentally friendly, and low-cost powder production, helping stone enterprises turn waste into treasure. Mainstream marble grinding process: Crushing → Feeding → Grinding → Classification → Powder Collection → Dust Removal.
The Shanghai Shibang LM Vertical Mill features high integration and large capacity, making it suitable for large-scale heavy calcium carbonate production lines. With an hourly output of 10–340 tons and adjustable mesh sizes ranging from 80 to 400, the system offers low energy consumption and a small footprint, making it ideal for large processing plants.
For small-to-medium-sized projects and waste material grinding, the MTW European mill is the preferred choice. Its curved scrapers enhance grinding efficiency, the frictionless spiral housing reduces power consumption, and the thin-oil lubrication system ensures greater reliability. Efficient classification guarantees a fine and uniform final product, meeting the requirements for general fillers and delivering a quick return on investment.
For producing ultra-fine heavy calcium carbonate powder used in high-end plastics and coatings, choose the LUM Ultra-Fine Vertical Mill or the SCM Ultra-Fine Powder Mill. The finished product ranges from 325–2500 mesh with D97 ≤ 5 μm, featuring high whiteness and excellent dispersibility, significantly enhancing the performance of downstream products. The equipment features negative-pressure sealing and highly efficient dust collection, ensuring a clean production site that meets environmental protection requirements.
The new-generation MTW6X Smart European mill and PMD Permanent Magnet Direct-Drive mill further reduce energy consumption and operational costs. They support remote intelligent monitoring, making operation and maintenance more convenient and long-term use more economical. Shanghai Shibang’s marble grinding solutions can flexibly process raw ore and scrap materials.
Equipment selection is precisely matched based on production capacity, finished product fineness, and budget: MTW/LM for standard heavy calcium carbonate; LUM/SCM for ultra-fine heavy calcium carbonate. The equipment is reliable, features long-lasting wear parts, and operates stably, helping enterprises reduce production costs, enhance product quality, and achieve resource recycling and sustainable development.
