Grinding Mill More Suitable For Feldspar Processing


Feldspar is a kind of aluminosilicate mineral containing calcium, sodium and potassium. It is the general name of Feldspar minerals.

Its main chemical components are SiO2, Al2O3, K2O, Fe2O3, Na2O and CaO, which are important rock-building minerals. Mainly used for manufacturing ceramics, enamel, glass raw materials, abrasive abrasive, in addition to potash fertilizer. Usually divided into two categories: orthoclase (potassium feldspar) and plagioclase. Mohs hardness: 6-6.5.

As for feldspar grinding powder, it is difficult to grind because of its high hardness. If the use of Raymond grinding, wear accessories should be used, and wearing parts will be very fast consumption. Generally, in the face of feldspar grinding, ball mill will be selected for processing. But the ball mill has the following disadvantages, making some customers in the choice of grinding machine caught in a dilemma.

In view of this problem, Shanghai Zenith Mineral Company, through the research of the technology research and development department, LM Series vertical roller mill, which is an ideal equipment in the grinding industry engaged in crushing, drying, grinding, separating and transportation, are advanced grinding equipment designed and developed by our company based on our 30 year’s experience in mill production as well as wide range of adoption of domestic and overseas advanced technology. It can be used in the preparation of pulverized coal, barite, gypsum, cement, electric power and so on.
