Limestone Raymond Grinder(ISO9001:2008)

1.Raymond grinder with ISO9001:2008 approved 2.Particle size form 80~600 mesh 3.Patent no: ZL2011201414398 4.1~7t/h

 The Applications Range of Limestone Raymond Grinder(ISO9001:2008)

This  Raymond grinder is the ideal solution for pulverizing almost any non-metallic minerals with Moh’s hardness below 7 and moisture content below 6%, such as marble, calcite, limestone, feldspar, fluorite, gypsum, talc , barite, dolomite, granite, kaolin, bentonite, bauxite, phosphorite, figuline, black lead, clay etc. The fitness of the final product can be adjusted as required in the range of 80-400 meshes.

 

Equipment features of Limestone Raymond Grinder(ISO9001:2008)

1, grinding force big: host grinding system uses four roll pressure device to increase grinding force 

2. grinding large area: the grinding and grinding ring from the height of the 160mm increased to 200mm.

3.shovel material using super large: use the big Shovel blade, makes the material tackles the into grinding roll and a magic ring between grinding. 

4, classifying precision: using super-large grading turbine, percent of pass is high, deal with big air volume. And grading impeller end and powder outlet end forming palace type sealing, the system doesn't easy to form short-circuit powder, classification precision is high. 

5. double whirlwind collector: adopts the parallel double whirlwind collector, collecting efficiency over 85%, than the single tornado collector 10% collection efficiency. 

6. afterwind adopts baghouse collecting, no dust pollution.

Working Principles of Limestone Raymond Grinder(ISO9001:2008)

Firstly, 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 airflow system is closely sealed up and circulated under condition of negative and positive pressure.
