Gravel has numbers of source and names. Nature gravel is Large called conglomerate, they are a common geological feature, being formed as a result of the weathering and erosion of rocks. While natural gravel deposits are insufficient for human purposes, gravel is often produced by quarrying and crushing hard-wearing rocks, such as sandstone, limestone, dolomite or basalt.
Gravel ultrafine grinding line
Our gravel grinding mills include Raymond mill, HGM ultrafine grinding mill (HGM80/ HGM90/ HGM100/ HGM100/HGM125). Raymond mill is the vertical grinding mill, which is popular in many countries and has very long history. HGM ultrafine grinding mill is special for super thin grinding. You can choose suitable gravel grinding mill depends on your gravel size, hardness, capacity and your cost budget.
Gravel ultrafine grinding line:
Clirik has the best gravel ultrafine grinding line. Under the same finished final size and the same motor power, the capacity of micro powder grinding mill is twice as much as jet mill, mixing grinder and ball mill. And the application of pulse deduster and muffler greatly alleviates dust pollution and noise. If you want to reduce the cost of production you can choose our gravel ultrafine grinding mill.
Raw gravel first enters jaw crusher to be crushed to smaller size. They are lift to storage room by elevator. Vibrating feeder will feed materials into grinding chamber evenly and gradually. After being grinded, the quartz powder will be blow to cyclone by blower. Then the gravel powder will be transferred to storage room through pipes, and then will be discharged as final products.
Dolomite is a carbonate mineral composed of calcium magnesium carbonate. Dolostone (dolomite rock) is composed predominantly of the mineral dolomite with a stoichiometric ratio of 50% or greater content of magnesium replacing calcium, often as a result of diagenesis. Limestone that is partially replaced by dolomite is referred to as dolomitic limestone. Raw dolomite first enters jaw crusher to be crushed to smaller size. They are lift to storage room by elevator. Vibrating feeder will feed materials into grinding chamber evenly and gradually. After being grinded, the quartz powder will be blow to cyclone by blower. Then the dolomite powder will be transferred to storage room through pipes, and then will be discharged as final products. >>The Application of dolomite ultrafine powder grinding mill: HGM series dolomite ultrafine powder grinding mill is mainly applied to non-inflammable, non-explosive and brittle materials with Mohs hardness under six. Such as calcite, chalk, gravel, dolomite, kaolin, gypsum, etc, totally more than 100 kinds of materials. Product fineness can be controlled between 325~2500 mesh. >>Working Principle of dolomite ultrafine powder grinding mill: 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 powder 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. Should you have any questions, please do not hesitate to contact me.

This mill can be used widely in metallurgy, chemical combination, construction, mining, cement and other fields. Performance features A. High efficiency and low consumption. At the status of the same material, power, and the same finish fineness, its production capacity per hour is 40% higher than other jet mill and mixing grinder. B. Durable. At the status of the same material, power, and the same finish fineness, hgm ultrafine mill wear life is longer than impact mill and turbine mill. C. Advanced grind device. Since there is no rolling bearings and bolts designed in the grinding space, it can avoid machinery breakdown problem due to long and hard use for bearing and airproof parts and sudden falling for rolling bears and bolts. D. Excellent frequency and speed conversion device. It can easy to adjust granularity evenly. E. Wide fineness adjustable function. Finish fineness is adjustable between 400 to 3000 mesh.
