PCL Sand Making Machine:
Sand Making Machine (namely PCL Vertical shaft impact crusher) is of high-power and low-consumption, which is designed depending on several year’s hard work and study of mechanical mining equipment. Sand Making Machine absorbed the advanced technology of the same products of Barmac Company of America, now is of the international level. Sand Making Machine plays an important role in crushing minerals into pieces.
Our super pressure trapezium grinder mill has got the CE Certificate.
Super pressure trapezium grinder mill is the new grinder mill. Super pressure trapezium grinder mill is researched and designed by our experts basing on long term experience of high pressure
suspension grinder study, and the Super pressure trapezium grinder mill is according to number of customers' using requirement and suggestion home and aboard. Super pressure trapezium grinder mill is that it owes five patented technologies as trapezium working surface, flexible connection, roll linked pressure boost, etc. Super pressure trapezium grinder mill is also equipped with high efficiency centrifugal induced draught fan and so Super pressure trapezium grinder mil makes this machine research an advanced level of powder manufacture.
Super pressure trapezium grinder mil is mainly consist of main engine, speed reducer, powder concentrator, induced draught fan, bag dust collector, piping device, integrator, and motor etc. And Super pressure trapezium grinder mill also can grind all kinds of nonflammable and non -explosive minerals whose Moh's hardness is lower than 9 and humidity is lower than 6%.
Working Principle:
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 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.
Advantage:
The diameters of each part of rollers and rings are different, the upper part is big and the lower part is small, then they formed a trapezium form. This form can reduce materials’ sliding speed downwards and prolong the grinding time for materials, thus the grinding efficiency is increased.; the pressing springs have the functions of balancing and pressure increasing; the flexible connection can make the mill stable, decrease the shocking and avoid sympathetic vibration; high density powder separator impeller decreases the air resistance and increases powder collecting fineness and capacity; the efficiency of energy saving and high efficient centrifugal blower is as high as 83%.
