Potassium feldspar (potassium salt) is a core raw material in the ceramics, glass, potash fertilizer, and welding materials industries. The fineness, purity, and whiteness of the ground powder directly affect the quality of ceramic glazes, the transparency of glass, and the utilization rate of potash fertilizer. Traditional equipment suffers from inconsistent fineness and high pollution levels, making it difficult to meet the requirements of high-end ceramics and fine chemicals.
Shanghai Shibang offers complete equipment solutions—including the MTW European mill, LM vertical mill, LUM ultra-fine vertical mill, and SCM ultra-fine powder mill—tailored to the hardness and grinding characteristics of potassium feldspar. These systems enable efficient, clean, and stable powder production, facilitating the high-value utilization of potassium ore resources.
Potassium feldspar grinding process: Crushing → Feeding → Grinding → Classification → Powder Collection → Dust Removal. Shanghai Shibang’s LM Vertical Mill features high capacity and efficiency, making it ideal for large-scale potassium feldspar grinding. With an hourly output of 10–340 tons and adjustable fineness from 80 to 400 mesh, it integrates drying and grinding into a single unit, simplifying the process and reducing investment costs. Its fully sealed, negative-pressure operation ensures environmental safety and is suitable for large and medium-sized mining and chemical enterprises.
For small and medium-sized production lines, the MTW European mill is recommended. Its curved scrapers enhance efficiency, while thin-oil lubrication ensures reliable operation. The high-efficiency cage classifier guarantees precise fineness and uniform, stable finished products, meeting the requirements for ceramic bodies and general raw materials, offering excellent cost-effectiveness.
For the production of high-end ceramic glazes and ultra-fine potassium fertilizer raw materials, the LUM Ultra-Fine Vertical Mill or SCM Ultra-Fine Mill can be used. The finished product ranges from 325 to 2500 mesh, featuring a concentrated particle size distribution, low iron content, and high whiteness, significantly enhancing the quality of downstream products. The equipment consumes 70% less energy than air-jet mills, offering high efficiency and stable operation, making it suitable for the production of high-end, finely processed raw materials.
Shanghai Shibang’s feldspar grinding equipment selection is scientifically optimized: large-scale production lines are equipped with LM vertical mills; small-to-medium capacity lines with MTW European mills; and high-end ultra-fine powder production with LUM/SCM mills. The equipment’s wear-resistant components are made of high-hardness alloys, ensuring durability and minimizing impurity contamination; the intelligent control system is easy to operate, with precisely adjustable operating parameters to guarantee consistent product quality; Full-process dust removal and noise reduction meet environmental protection and safety supervision requirements.
Leveraging professional expertise and extensive experience, Shibang’s potassium feldspar grinding solutions have been widely adopted in ceramic production areas and potassium ore processing bases, helping enterprises enhance product value and market competitiveness.
