1.The cylindrical mill adopts the driving type edge-driving, center-driving, edge-driving with multi-point meshing, etc; driven by asynchronous motor +reducer +pinion and gear as well as synchronous motor +
2.Generally supported by static-dynamic pressure bearing on both ends. Fuuly closed self-aligning 120º osculation rocker bearing is used. Also single or double slipper staic- dynamic bearings can be used. The bush is made by NC machine.
3 .The large open gear is designed using AGMA standard, Equipped with reliably sealed gear housing and grease ahtomatic spraying lubrication system.
The shell is key part of a mill. Carry out finite element analysis on it with computer to ensure the reliable operation;
4 .The shell is automatically welded, ultrasonic inspected, wholly annealed and machined by large special machine tools on one chucking; there special seal on static-dynamic connection parts , ch as feed and discharge hoper, trunnion, etc, to prevent oil and slurry leakage;
5 .The liner is of wear-resistance material mad by our company, wich has been specially heat-treated, with high hardness and long service life. Also other wear-resistance casting or rubber liner can be used;
6. There are slow speed drive for medium and large mill;
7.The high and low pressure lubricating station is equipped for medium and large mill;
8.The control and protection system is controlled by PLC. technical advantages
This mill is center driven, which adopts slipper bearing support, new type combination design baffle plates and discharge grate, to raise crushing, grinding and screening efficiency. 2.2
The material is fed into the rough grinding bin through the feeding device; then crushed under the impact and grinding of grinding agent (steel ball with longer diameter), and the finer material enter into the fine grinding bin through double layered baffle plates and other material which can not enter into the fine grinding bin will continue be crushed in the rough grinding bin; the material which enter into fine grinding bin will entail further impact and grinding of smaller grinding agent, and the finished goods which meet the degree of fineness will enter into discharging device and been discharged from the mill.
The mill mainly consists of feeding device, slipper bearing, rotating part, discharging device, lubricating device of slipper bearing. 3.1 Feeding device
- Application IndustryCement Plant
- Output70~720 t/h
- Final Product Fineness80 μmR 12~15%
- Power Consumption of System17~20 kWh/t
Our vertical raw mill has various advantages when compared with other similar machines. Detailed information will be given in the following.
1. High grinding efficiency: advanced grinding principles makes it possible to save as much as 20~30% power consumption when compared with the ball mill. With the increasing of moisture content, it can save more and more electricity.
2. Strong drying capacity: it can make use of the hot waste gases from the kiln to do drying, and it is capable of drying and grinding raw materials with moisture content as much as 15%.
3. Small in size, and simple process flow: it has integrated crushing, drying, grinding, separating and conveying into one body.
4. Low noises and little dust: there is no direct contact between the grinding rollers and grinding disc. So metallic impact is avoided and its noises is 20~25 decibels lower when compared with ball mill. Totally closed negative pressure operation has employed by this vertical raw mill, so there is no dust during the operation, which can help to keep the production environment clean.
5. Low wear rate and little metallic pollution: its metal wear is only 5~10g/t.
6. With stable chemical composition and even particle size, its products are quite easy to calcine.

This vertical coal mill is typically designed to process materials in medium hardness, like soft coal or bituminous coal, and it is mainly used in positive pressure pulverizing system of soft coal. It is widely used in electricity field, metallurgy sector, building material industry, chemical industry, and so on.
