Introduction to Dolomite
Dolomite is a kind of carbonate mineral, including ferroan-dolomite and mangan-dolomite. Dolomite is the major mineral component of dolomite limestone. Pure dolomite is white, some may be gray if contains iron.
Application of dolomite
Dolomite can be applied in construction material, ceramic, glass, refractory material, chemical, agriculture, environmental protection and energy saving fields. Dolomite can be used as basic refractory material, blast furnace flux,calcium magnesium phosphate fertilizer, and the material of cement and glass industry.

Analysis on grinding mill models
1. HC Series Grinding Mill: low investment cost, high capacity, low energy consumption, steady operation, low noise. Disadvantages: lower single capacity, not large-scale equipment.
2. HLM Vertical Mill: large-scale equipment, high capacity, steady operation. Disadvantages: higher investment cost.
3. HCH Ultra-fine Mill: low investment cost, low energy consumption, high cost-effective. Disadvantage: low capacity, multiple sets of equipment is required to build a production line.
4.HLMX Ultra-fine Vertical Mill: able to produce 1250 mesh ultra-fine powder, after equipped with multilevel classifying system, 2500 mesh micro powder can be produced. The equipment has high capacity, good production shape, is an ideal facility for high quality powder processing. Disadvantage: higher investment cost.
Stage I: Crushing of raw materials
The large dolomite material is crushed by the crusher to the feed fineness (15mm-50mm) that can enter the grinding mill.
Stage II: Grinding
The crushed dolomite small materials are sent to the storage hopper by the elevator, and then sent to the grinding chamber of the mill evenly and quantitatively by the feeder for grinding.
Stage III: Classifying
The milled materials are graded by the grading system, and the unqualified powder is graded by the classifier and returned to the main machine for re grinding.
Stage V: Collection of finished products
The powder conforming to the fineness flows through the pipeline with the gas and enters the dust collector for separation and collection. The collected finished powder is sent to the finished product silo by the conveying device through the discharge port, and then packaged by the powder tanker or automatic packer.
Application examples of dolomite powder processing
Dolomite mill: vertical roller mill, Raymond mill, ultra-fine mill
Processing material: Dolomite
Fineness: 325 mesh D97
Capacity: 8-10t / h
Equipment configuration: 1 set of HC1300
Hongcheng's complete set of equipment has compact process, small floor area and saves plant cost. The whole system is fully automatic control, and a remote monitoring system can be added. Workers only need to operate in the central control room, which is simple to operate and saves labor cost. The performance of the mill is also stable and the output reaches the expectation. All the design, installation guidance and commissioning of the whole project are free. Since the use of Hongcheng grinding mill, our output and efficiency have been improved, and we are very satisfied.
