Limestone is also named as CaCO3, Limestone under high temperature and high pressure, become soft, and the minerals change when the anew crystallization of limestone. The main component is calcium and dolomite, many colors, usually have a clear pattern, a lot of mineral particles. Mohs hardness between 2.5 and 5. Because limestone is generally contain impurities, and limestone by carbon dioxide, carbide, the role of water vapor in the atmosphere, but also easy to weathering and erosion, and make the surface soon lose luster.
How To Choose 1250 mesh limestone Powder processing Plant:
Clirik Machinery devoted to provide limestone processing and grinding solution,The recommended limestone Powder grinding Machine is HGM micro powder milling machine, which meets client’s requirements of excellent fineness, reliable performance and favorable price.Clirik limestone Grinding Mill is mainly applied to non-inflammable, non-explosive and brittle materials with Mohs’ hardness under six. Such as calcite, chalk, limestone, dolomite, kaolin, talc, etc, totally more than 100 kinds of materials. Product fineness can be controlled between 325~3000 mesh.
If you want to processing limestone powder,please choose the following plant:
>> Coarse powder grinding mill: output size below 3mm, capacity 100t/h
>> YGM high pressure suspension grinding mill: output size between 15-425meshes
>> HGM three-ring micro powder milling machine: output size between 200-3000meshes (can be adjusted)
1. Application of 1250 mesh limestone powder processing plant
1250 mesh limestone powder processing plant can not only process the limestone, but also for the medium and low hardness, superfine powder processing Mohs hardness of less than 7 of non flammable and explosive brittle materials, such as calcite, chalk, limestone, dolomite, silica, kaolin, bentonite, limestone, magnesite, talc, illite, vermiculite, sepiolite, pyrophyllite, attapulgite, rectorite, diatomite, barite, gypsum, alum stone, limestone, fluorite, phosphate rock and potassium ore, pumice and other 100 kinds of materials.
2. The structure of 1250 mesh 1250 mesh limestone powder processing plant
limestone powder grinding machine full set of configuration consists of hammer crusher, bucket elevator, storage hopper, vibration feeder, grinding, grading machine, double frequency conversion main cyclone powder collector, high voltage pulse dust removal system, wind machine, air compressor, electric control system. According to the needs of the user can also be equipped with a broken machine, hoisting machine, storage hopper, electromagnetic vibration feeder and electric control cabinet and other auxiliary equipment, according to the requirements of users equipped with lifts, storage bin, electric control cabinet, electromagnetic powder feeder, crusher, milling equipment.
3. The working principle of the 1250 mesh limestone powder processing plant
When working, the host of ultrafine pulverizer motor through reducer drives the spindle and the rotary table drive pin, and the edge of the dozens of roller in the rolling mill ring raceway.
limestone raw material by the hammer crusher into small particles by the elevator into the storage bin, again through the feed tube vibration feeder and the tilt of the disc, the bulk of limestone particles evenly to the upper part of the rotary table.
Effect of limestone powder dust under the centrifugal force to the circumference of scattered, and fall into the grinding roller is ring roll impact, rolling, grinding ring, three ring road after processing into the limestone powder, high pressure blower through the pumping action of the external air into the machine, and the crushed limestone powder with selected powder machine.
Selection of the rotation of the impeller powder machine make coarse limestone powder down heavy grinding, with fine powder with airflow into the cyclone powder collector and from the lower part of the discharge valve discharge is the limestone powder final, with a small amount of fine dust in the air and then through the pulse dust collector after purification by the blower and silencer discharge.
