Introduction of Phosphate rock mill

SBM Phosphate rock mill is the latest grinding mill. SBM Phosphate rock mill is researched and designed by our experts basing on long term experiences of mill research and development, and according to numbers of customers' using requirements and suggestions home and aboard. Our Phosphate rock mill adopts our patented technologies, like trapezium working surface, flexible connection, roller linked pressure boost, etc. At present ,our Phosphate rock mill not only has a large number of customers at home , but also exported to dozens

of countries abroad.our Phosphate rock mill have exported to more than 130 countries, such as USA, Ukraine, Japan, Poland, France,

Brazil,Mexico, Germany, Indonesia, India, Vietnam, Philippines, Canada, South Africa, Zimbabwe, Russia, and so

on.

working principle of Phosphate rock mill

Large materials are crushed by Jaw crusher to the needed sizes firstly, then the materials are elevated to storage hopper by bucket elevator, third, the materials are fed into the grinding chamber for grinding by vibrating feeder equably and continuously. The powder after grinding goes upwards together with the airflow, after separating by powder separator, those which can meet the fineness requirement enters into the cyclone powder collector through pipe together with the airflow, and then discharged from the discharge valve as final products. The airflow is sucked into centrifugal blower through wind recycling pipe at the upper part of cyclone powder collector. The mainframe is driven by the speed reducer through the central axis in the Phosphate rock mill. The quincunx stand connected with the upper part of central axis, at the quincunx stand, rollers are set and by which the vibrating pivot formed. Below the quincunx stand and rollers there is shovel system. Materials are fed into the space between rollers and shovels when they are turning, and then be grinded by the pressure produced when rollers are turning, thus powder is made.

The application of Phosphate rock mill

The Phosphate rock mill for grinding barite, limestone, mica, talcum, quartz, calcite, granite, porcelain clay,

basalt, ypsum,gold, iron ore, bauxite, copper, cement, coal etc. So it has wide application in powder making industry

of construction, mining and paper-making and so on

Advantages of Phosphate rock mill :

a.High Efficiency

Under the same finished final size and the same motor power, the capacity of Phosphate rock mill is twice as much as jet mill, mixing grinder and ball mill, and energy consumption decreased 30%.

b.Long lifecycle of spare parts

The ring and roller are forged by special material with high utilization,the lifetime can reach 2-5 years for grinding calcite carbonate.

c.High safety and reliability

As no rolling bearings or screws in grinding cavity, there are no problems caused by bolts shedding or rapid wear of bearings and seal components.

d.High fineness, flexible adjustment

The final fineness of the grinding materials can be adjusted between 325 meshes and 2500 mesh (47-5 micron), and the product fineness can reach D97≤5μm.

e.Environment-friendly

The application of pulse bag filter and muffler greatly alleviates dust pollution and noise.

Advanced intelligent speed control device

Convenient adjusting, more uniform particle size.
