Feldspar Crushing And Grinding Mill Equipment for Sale
Feldspar is a common raw material used in glassmaking, ceramics, and sometimes used as a filler and extender in paint, plastics, and rubber. In glassmaking, alumina from feldspar improves product hardness, durability, and resistance to chemical corrosion. In ceramics, the alkalis in feldspar act as a flux, lowering the melting temperature of a mixture. Fluxes melt at an early stage in the firing process, forming a glassy matrix that bonds the other components of the system together. In the US, about 66% of feldspar is consumed in glassmaking, including glass containers and glass fiber.
Feldspar Processing Equipment for Sale
From the completed flotation process, the feldspar float concentrate is dewatered to 5 to 9 percent moisture. A rotary dryer is then used to reduce the moisture content to 1 percent or less. Rotary dryers are the most common dryer type used, although fluid bed dryers are also used. Magnetic separation is used as a backup process to remove any iron minerals present.
Following the drying process, dry grinding is sometimes performed to reduce the feldspar to less than 200 Mesh for use in ceramics, paints, and tiles. Drying and grinding are often performed simultaneously by passing the dewatered cake through a rotating gas-fired cylinder lined with ceramic blocks and charged with ceramic grinding balls. Material processed in this manner must then be screened for size or air classified to ensure proper particle size.
XSM provides complete range of feldspar processing equipment for sale, such as quarry machine, mining equipment, crushing plant, grinding mill, screening plant, separation machine, drying and washing plant, processing equipment etc.
Ball Mill for Feldspar Production
Ball is is good choice for feldspar powder production. High energy ball milling is a simple, effective and productive method to produce various fine powders in high energy ball mill plant. Other things being equal, the higher the intensity and duration of grinding and the smaller the weight and size of particles of milled source powder, the smaller the average size of the powder particles. Along with decreasing particle size, grinding produces microdeformation of the crystal lattice of the ground material, and part of the energy is spent to create microstresses, which slows down the grinding of the powder.
