High Pressure Suspension Mill is mainly made up of the mainframe, separator, blower, finished powder cyclone collector, bag filter and connecting pipes, etc. According to users need, the mill can also be equipped with accessory equipments like crusher, bucket elevators, hopper, electromagnetic vibrating feeder and switch box etc. Inside the mainframe, the roller subassembly is suspended on the roller suspender through horizontal supporting axis, and the roller suspender fixed up with the main shaft and shovel stand. Located outside of the roller bearing house, the pressure springs make rollers push down the inside surface of ring through horizontal supporting axis. Shovels installed on the shovel stand and rollers rotate together when the motor drives main shaft through transmission device and the rollers roll appressed the inside surface of ring and rotate at the same time. The separator impellers are driven by motor through transmission device to rotate, more higher the speed of separator impellor, more fine the powders been separated. We are also listed amidst the outstanding High Pressure Suspension Grinding Mill Manufacturers in the market. Working Principle of High Pressure Suspension MillWhen entering grinding chamber, the raw materials are shoveled up by the shovels and grinded between the rollers and ring; the materials after grinding are brought into the separator along with the air from the blower, and the qualified fine powder became final products and come into the cyclone powder collector, the other unqualified powder fall down to be re-grinded. The circular air returns back to the blower that the above process will be repeated, and the remaining air enters the bag filter in order to protect the environment. Characteristics

• Compared with other mills, its capacity increases by 10%-20% under the same power condition, and compression force of rollers to material improve 800-1200kgf under the force of high-pressure spring.
• Size of final product can be 0.613mm (30mesh) 0.033mm (425mesh). Some can reach the fineness of 0.013mm (1000 mesh).
• High Pressure Suspension Mill meets the requirement of national dust-dump standard.
• The separator can be adjusted very easily.
• The multi-class seals are adopted to keep the grinding equipment tightly closed.

After many years of practice and improvement, its structure is getting perfect day by day. For low consumption, low investment, environment friendly, small occupation area, and more efficient than the traditional mill, Raymond Mill is widely used in the field of metallurgy, building materials, chemical industry and mining to process powder. The series is used in grinding the non-flammable and non-explosive stuff which has the Mohs hardness below 7, humidity less than 6%, such as gypsum, talc, calcite, limestone, marble, feldspar, barite, dolomite, granite, kaolin, bentonite, bauxite, iron ore etc., the final products change from 613 micron to 44 micron. Through the function of separator and blower, Raymond Grinder Mill can meet different customers demand. Moreover, we are reckoned as one of the most prominent Raymond Grinding Mill Manufacturers and Suppliers from China. Structure of Raymond Mill :

• The whole plant is a vertical structure of strong systematic characteristic, so it occupies small area. From crushing of raw material to grinding and packing is an independent production system.
• Compared with other milling plants, its passing ratio achieves 99%, this is what other mill cannot reach.
• Driving system of main frame adopts airtight gearing and pulley, drives smoothly and operates reliably.
• Main parts of the whole plant are made from cast and steel of high quality. The techniques is so subtly that insures the durability of whole plant.
• The electric control system is centralized controlled, so the automaticity is high, no people are needed in the operating room.

Working PrincipleFirstly, raw material is crushed by jaw crusher to the size required, and then the crushed materials are elevated into a hopper from which the material is transported through the electro-magnetic vibrating feeder, evenly and continuously into the grinding chamber for powder-processing. The rollers oscillate outward to press the ring because of the centrifugal force and the shovel scoops up the materials, send to the middle between ring and roller to accomplish the grind. After this, the ground stuff is carried by the air from the blower into the separator for screening. The fine powers are blow into the cyclone collector and are poured out through the output-powder valve as the final products and the rough stuff after the screening will be recycled back into the grinding chamber for regrinding. The sets airflow system is closely sealed up and circulated under condition of negative and positive pressure.

Pcl Series Sand Making Machine is of high-power and low-consumption, which is designed depending on several years hard work and study of mechanical mining equipment. Pcl Sand Making Machine absorbs advanced technology of the same products of Barmac Company of America, now it is of the international level. Sand Making Machine plays an important role in crushing minerals into pieces. PCL vertical shaft impact crusher is widely used in all kinds of minerals, cement, refractory material, carborundum grain, glass raw material, construction sand, stone stock and all kinds of metallurgy slag, especially carborundum, sintered bauxite, magnesite, such materials are with features of very hard and anticorrosion. And Sand Making Machine is more productive than other kind of crushers. Moreover, we are also recognized as one of the most eminent PCL VSI Crusher Manufacturers. Features

• Simple structure and low operating cost.
• High crushing ratio with low consumption
• Function of fine crushing and crude grinding
• Slightly influenced by moisture content of material, and the max moisture content is about 8%
• More suitable for crushing mid-hardness and hardness materials
• Cubic shape of final products, high density of piling up and low iron pollution
• More wearable and easier maintenance
• Low working noise (lower than 75 decibel) and light dust pollution.

Vsi Sand Making Machine is Newly Researched Equipment, with International Advanced Level. Technology and Modern Processing Equipment Make It a Leading Role in this Industry. Vsi Sand Making Machinery is Widely Used for Artificial Sand, in Metal and Non-metal Ores, Cement, Refractory Material, Bauxite, Silicon Carbide, Glass Material, Building Material. We are Reputed as One of the Most Trusted Vsi Series Sand Making Machine Suppliers. featuresadvanced Double-pump Oil Lubrication System Guarantee Shaft Bearing Lower Temperature Increase, Longer Life Time, More Reliable Operation.main Shaft is Equipped with Imported Precision Rolling Bearing.
