Dolomite powder milling machinery

Project Background

Dolomite crystal belongs to carbonate mineral of trigonal system. It can be used as the fire-resistant lining of reforming furnace used when making steel

Introduction of Material

Dolomite crystal belongs to carbonate mineral of trigonal system. It can be used as the fire-resistant lining of reforming furnace used when making steel, slag former, cement stone, glass solvent, ceramic industry, fertilizer, building& ornamental stones, paint, pesticide, medicine, etc. what’s more, in the fields of building materials, ceramics, glass & fire-resistant materials, chemical industry & agriculture, environment protection, energy conservation, etc, dolomite crystal plays an important role.

Dolomite Grinding Process & Principle

The dolomite ore mills manufactured by Shanghai Zenith Machinery Co. Lit. can be divided into several kinds: high-pressure mill, overpressure trapezium mill, three-round medium-speed fine mill, vertical mill, etc. Zenith unites multiple advantages of the former grinding machines, take the needs of processing in the new environment into consideration, and systematically upgrade the technology of the dolomite grinding machines. The production process of, both dolomite and other ore materials, represents the production features of modern energy-saving, environment-protection, large scale and high efficiency. These machines mainly adopt the newest technologies, which gain many patents, like gear-integrated drive, internal oil lubricating system, cambered whirl tube, etc. The scraper knife of traditional mill is abraded seriously on the blade. As the scraper knife of the whole, it is a waste of time to change the knife when abraded. Also, the replacing time increase. However, trapezium dolomite mill of European type adopts high-wearing proof alloy materials with long working life. Only the blade of the knife needs changing, which improve the use ratio of materials.

Dolomite Grinding Process Applications

Dolomite can be used for building materials, ceramics, glass and refractories, chemicals and agriculture, environmental protection, energy and other fields. After dolomite milling processing, the dolomite sand can be 6-10 mesh, 10-20 mesh, 20-40 mesh, 40-80 mesh, 80-120 mesh; dolomite after grinding mill processing, the dolomite ultrafine powders can be 140 mesh, 325 mesh, 600 mesh, 1000 mesh, 1600 mesh.

Dolomite is used as an ornamental stone, a concrete aggregate, a source of magnesium oxide and in the Pidgeon process for the production of magnesium. It is an important petroleum reservoir rock, and serves as the host rock for large strata-bound Mississippi Valley-Type (MVT) ore deposits of base metals such as lead, zinc, and copper. Where calcite limestone is uncommon or too costly, dolomite is sometimes used in its place as a flux for the smelting of iron and steel. Large quantities of processed dolomite are used in the production of float glass.

In horticulture, dolomite and dolomitic limestone are added to soils and soilless potting mixes as a pH buffer and as a magnesium source. Home and container gardening are common examples of this use.

Dolomite Powder Grinding Mill plant

SBM Machinery devoted to provide Dolomite processing and grinding solution,The recommended Dolomite Powder grinding Machine is YGM raymond Mill and HGM Ultrafine Mill, which meets client’s requirements of excellent fineness, reliable performance and favorable price.SBM Dolomite Grinding Mill is mainly applied to non-inflammable, non-explosive and brittle materials with Mohs’ hardness under six. Such as kaolin, limestone, calcite, marble, talcum, barite, gypsum, dolomite, bentonite mud, mica, pyrophyllite, sepiolite, carbon black, diatomite, graphite, alunite, fluorite, potassium feldspar, phosphorite, pigment, up to 200 kinds. Product fineness can be controlled between 0~3000 mesh.

Dolomite Stone Grinding Machine also is called dolomite mill or Raymond Mill. The Dolomite Grinding Machine can be use for grinding of dolomite stone. After being grinded by the Dolomite Stone Grinding Machine, the dolomite powder fineness can be up to 325 mesh.

After being grinded by the dolomite mill , the dolomite powder can be used in many industries such as Refractory, slagging agent, cement, glass fluxing agent, ceramic industry , architectural,etc.

Features of Dolomite Mill as as follows

The whole dolomite mill plant (Raymond Mill) is vertical structure of strong systematic characteristic, so it occupies small area. From crushing of dolomite to grinding and packing is an independent production system.

Compared with other milling plants, its passing ratio achieves 99%, this is what other mill can not reach.

Driving system of main frame adopts airtight gearing and pulley, drives smoothly and operates reliably.

Main parts of the whole plant are made from cast and steel of high quality. The technics is so subtly that insures the durability of whole plant.

The electric control system is centralized controlled, so the automaticity is high, no people are needed in the operating room.

The capacity of the dolomite stone grinding machine can be from 0.2 t/h to 20 t/h.
