Granite Grinding Machine and Mill Process Line

 

Granite (Whose etymology is granum from Latin, meaning grain or particle) is kind of igneous rocks formed by the condensate of magma below the surface. The main component of granite mine is quartz, feldspar and mica. Usually feldspar amount in the granite rocks is more than quartz. Granite rocks’ color is usually yellow with pink, and gray. Granite rocks are of hard texture, beauty color and so it is very good building materials. The crushed granite rocks can also be made of cement or to fill dam. In addition to being used as advanced architectural decoration engineering, the hall ground, granite mine is also the best material choice for outdoor sculpture.
Granite is widely distributed in the earth surface, and is one of the natural rocks discovered and used by human early. Many non-ferrous minerals such as copper, lead, zinc, tungsten, tin, bismuth, molybdenum; precious metals such as gold, silver; rare metals such as niobium, tantalum, beryllium; radioactive elements such as uranium, thorium, etc., are all related to the granite mine. The density of granite is 2790-3070 kg/m3 and its compressive strength is 1000-3000 kg/cm2.
Granite and basalt both belong to volcanic rocks. As a kind of rocks with very broad distribution, granite have been produced in many countries, such as Poland, Vietnam, Canada, Sweden, South Africa, Lithuania, Latvia and Estonia, etc.
Granite Grinding Machine and Mill Process Line
HGM series Granite Grinding Machine is mainly applied to non-inflammable, non-explosive and brittle materials with Mohs hardness under six. Such as calcite, chalk, limestone, dolomite, kaolin, gypsum, etc, totally more than 100 kinds of materials. Product fineness can be controlled between 325~2500 mesh.
Performance and features Of Granite Grinding Machine:
1.        High efficiency
Under the same final size and power, the product capacity of ultrafine mill is twice than jet mill and agitation mill.
2.        Longer lifetime of spare parts
The roller and ring are made of special material, which improve the grinding efficiency a lot. For same material and final size, the lifetime of its wearing parts can reach to more than one year, about 2-5 times as long as that of vertical shaft impact crusher and turbo-mill. Especially when handling Bentonite and calcite, the lifetime can reach 2-5 years.
3.        High safety and reliability:
There are no rolling bearings and bolts in grinding cavity, so problems caused by bolts shedding or wear of bearings and seal components will never happen.
4.        High fineness of products
The product fineness can reach D97=<5um.
5. Environment friendly
The application of pulse dust collector and muffler reduce the pollution and noise of the dust, which has reached national environment protection standard.
Working Principle of Quartz Grinding Machine:
Working principle of Granite Grinding Machine:
The main bearing and each dial are driven by electromotor of main machine through reducer, and numbers of rollers, which are rolling in the ring, are driven by dial through plunger. After crushed by hammer crusher, the big materials become small ones and are sent to storage hopper by elevator and further sent to the middle of first dial evenly by the electromagnetic vibrating feeder and feeding pipe. The materials will be driven to the edge of dial by centrifugal force and fall down into the ring, crushed and grinded by roller, and become powder after production of three rings. The high pressure centrifugal blower will inhale air from outside and blow the crushed materials to classifier. The rotating turbo in the powder concentrator will make the coarse materials return to the mill and reground, while the fineness will mix with the air and go into the cyclone and be discharged in the discharge bin, which is at the bottom of it. The air, which mixed with very little fineness, will be purified by impulse duster and discharged by blower and muffler.
