Vertical Milling Machine
Vertical milling machine is the newest grinding machine, which integrates the advanced international technology and years of mill-producing experience . The vertical milling machines are ideal equipments that integrates crushing, drying, grinding and grading conveyor all together.
Vertical milling machine application
Vertical milling machines are mainly applied to proceed the powder crushing manufacturing of the materials such as calcite, limestone, light dry stone coal, barite, fluorite, glaze, slag, wollastonite, kaolin, vermiculite, mica, feldspar, brucite, spores, potassium salt slag, garnet , quartz,etc. And the vertical milling machine can also be used to the non-metal mining areas with the Mohs hardness of less than 7degree ,such as mining metallurgy, chemical industry, electronics, medicine, food, daily chemical, agricultural, building ,and so on.
Vertical Coal Milling Machine
Coal mill is an efficient tool for grinding coals into fine powder in coal mining industry. According to its fineness and working principles, we divide coal mill into coarse power coal mill and fine coal mill. Coarse powder mill is a kind of new high-tech milling machine to meet the requirements of coarse powder processing customers. It is the ideal equipment to replace Raymond mill, ball mill, and other traditional mill which only process fine coal powder materials.
Vertical Cement Milling Machine
With the continual increasing demand for portland cement and constant pressure for reduced energy consumption, producers are exploring a wide variety of cost-saving manufacturing options. One option is vertical roller mill technology for finish grinding.
Traditionally, plants used ball mills to grind clinker and gypsum into cement. The result: the majority (60%) of finish grinding in the world is still performed using the ubiquitous ball mill. Ball mills are cylindrical steel shells with steel liners. These rotating drums contain grinding media that tumble inside the cylinder. The grinding balls cascade and tumble onto the clinker and gypsum to produce cement. Almost all ball mills use a form of closed circuit grinding that returns material that is too coarse back to the ball mill inlet while material fine enough to meet product requirements is collected. The separator or classifier determines which particles will be returned and which particles are sufficiently fine. With an effort to increase production, ball mill physical size has increased almost to the physical limitation dictated by the gas velocities and accompanying pressures necessary for the process. Ball mills may not be the most efficient means of size reduction but their reputation for product consistency and their simplicity of operation have made them an historic plant favorite.
Vertical Milling Machine: Vertical Mill Features
1. Low operating costs. Combine the crushing, grinding, drying, classifier and elevator, the system of vertical mill is simple and occupation area is about 50% of ball mill system. Vertical roller mill can be installed outside, so it will reduce a large number of investment cost.
2. High efficiency. Compared with ball mill, vertical mill can save energy consumption 30%-40%.
3. Less wear and tear. The optimized roller and the high quality raw material make the machine's life longer.
4. High drying ability. As the hot air inside contacts directly with the material, drying ability is higher, and it saves energy. By regulating the air temperature, it can meet requirements with different humidity.
