Feldspar comprises of a group of minerals which are the most common rock forming minerals. Feldspar is by far the most abundant group of minerals in the earth's crust, forming about 60% of terrestrial rocks. Feldspars are relatively hard at 6 on Mohs' hardness scale. Feldspars are generally light-colored, including white, pink, tan, green, or gray. The color varies due to impurities within the crystal structure. Feldspar is the mineral that gives granite its pink, green or gray color. Feldspars play an important role as fluxing agents in ceramics and glass applications, and also are used as functional fillers in the paint, plastic, rubber and adhesive industries.
Feldspar grinding process
In the grinding process, crushed feldspar particles is grinded into powder with the fineness requirement of 200 mesh by grinding mill. Then we use magnetic separator to separate the Iron-containing material. According to the different feldspar, we choose the different mineral processing method such as gravity concentration and flotation.
Feldspar grinding machine
Ball mill for feldspar. The ball mill is an efficient tool for grinding various ores and rocks. It is suitable for grinding feldspar and it features with simple structure, easy to operate, wide range of applications, even final products, lower maintenance and operating cost and so on.
As high-efficient and energy-saving powder grinding equipment, vertical roller grinding mill and super thin grinding mill have been widely applied in the field of building materials, chemicals, fertilizer, metallurgy, mining, nonmetal, abrasive, refractory, ceramic, steel, thermal power, bricks, coal and so on. They are ideal grinding machine for grinding feldspar.
