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.
1.Small comprehensive Investment
LM Vertical Roller Mill integrates the function of crushing ,drying, grinding, powder separating and transportation, featuring simple system and compact layout, with the floor space of about 50% of that of the ball-milling system. And it can be arranged outdoors so as to greatly reduce the investment costs.
2.Low Operating Costs
The roller and the grinding plate of LM Vertical Roller Mill are made of high-quality materials and the roller does not contact the grinding plate directly, less wear;30%-40% lower than that of ball-milling system, high efficiency for grinding; The roller sleeve and grinding plate can be easily replaced by means of the service cylinder, so that downtime losses could be significantly reduced, Simple maintenance.
3.High quality finished product
The material only stay in the mill for a short time, which can reduce repeated grinding, and stabilizing the product quality; the product contains very little iron, the whiteness and purity of the product can be effectively guaranted; The rotor speed adjustable, can be ensured to satisfy different requirements for fineness.
4.High Environmental Protection Standard
The equipment can operates stably with little vibration, its noise is fairly low; The system is wholly sealed and work under negative pressure, free of dust spillover and environment friendly, with the emission meeting the national standard.
5.Automatic Control System
The equipment is provided with an expert automatic control system, realizing free switching between remote and local control to achieve easy operation and save labor costs.
