290 t/h Output VRM Vertical Grinding Roller Coal Mill For Cement/Pulverized Coal/Power Plant
Description
Cement vertical mill is mainly used for the grinding production of cement clinker. In recent years, with the improvement of vertical mill design and manufacturing technology and the innovation of grinding process, vertical mill has been successfully applied abroad as cement final grinding equipment.
【Applicable materials】: Vertical roller mill mainly grinds raw meal, clinker, mineral powder, slag, granulated blast furnace slag, limestone, coal powder, coke powder, coal gangue, fly ash, pozzolan, gypsum, calcite, pyrophyllite , clay, sand, bauxite, silica fume, etc.
【Production capacity】: Different materials, different processing capacity, see the technical parameter table below for details
【Application industry】: Cement chemical, coal, electric power and other industries.

According to the different physical and chemical characteristics such as moisture, grindability, product fineness and safety of various types of materials in various industries, we have developed highly targeted, mature, reliable, safe and efficient grinding technology and supporting equipment. The core equipment is HVM type. Vertical mills handle materials ranging from high humidity to dry materials, from extremely difficult to easy-to-grind materials, and the fineness of products ranges from coarse to fine. Provide scientific and reasonable complete process plan and equipment selection of vertical mill pulverizing system, and provide integrated powder processing solutions. Based on a large amount of engineering practice experience, most powder processing is mainly divided into the following three technological processes:
(1) Flow chart of double dust collection system
This process plan uses a cyclone dust collector for product collection, which can effectively reduce the working negative pressure of the system and the amount of gas passing through the dust collector. , raw ore, etc.
The dust collection device used in this process scheme can be a high-concentration electrostatic precipitator or a bag, and the outgoing gas directly enters the dust collector. This system reduces the number of equipment and simplifies the system configuration. It is mostly used for grinding cement clinker and slag. , steel slag, non-metallic minerals and other mineral materials.
The dust collection device used in this process scheme is an explosion-proof bag dust collector, and the outgoing gas directly enters the dust collector. At the same time, the system has good airtightness and high safety. It is mostly used for grinding raw coal, petroleum coke and other flammable and explosive materials in cement, metallurgy, coal chemical industry, lime kiln pellets, heat and energy industries.
