Vertical Mill
Vertical mill introduction
Raymond mill is a widely used grinding mill equipment designed in the USA 1906 year. According to the Raymond mill structure, we can divide it into 2R Raymond mill, 3R type Raymond mill and 4R Raymond mill etc.
Raymond mill is widely used in mining, cement plant, chemical grinding plant, non-metallic mineral processing industry as an important grinding equipment. Because of the Raymond mill's stable performance, strong adaptability, high performance-price ration, Raymond mill has been widely applied in various kinds mineral industries in recent 20 years.
Vertical mill application
Vertical mill is widely used in cement, electricity, metallurgy, chemical and non-metal industry. Because vertical mill features many technology advantages, it can grind these materials into powder as required fineness.
Vertical mill technology advantage
1. Automatic control devices equipped, remot control can be realized, the operation is easy and simple.
2. By turning the rocker well as oil jack maintenace, the hard surfacing, roller and ring can be maintained within short time, and reduce the loss because of stop operation.
3. The equipment is sealed, the whole system working in negative pressure, there is no powder overflow, clean operation environment.
4. Small vibration, low nnoise.
Vertical mill working principle
Electric motor through a speed reducer drives the disc rotation, material from the feeding port to disc central, under the action of centrifugal force to the disc edge mobile and by the roller compacted, crushed material from the disc edge overflow, at the same time being from the nozzle ring (wind ring) high speed upward hot air flow to and vertical mill one of the high powder grinding machine, coarse powder separator after the returned to the grinding table, to grinding; fine powder with the airflow mill outlet, in the system of collecting device collects down, namely product.
LM150K type mineral ore grinding mill includes elevator, iron remover, belt conveyor, raw material hopper, closed belt feeder, vertical mill, impulse dust catcher, screw conveyor, wind pipe, muffler etc.
Vertical mill main structure
The main structure consists of classifier, roller, illstones, pressurization device, deceleration machine, moror, shell bmody, etc. Roller is the main part to grind the maerials into powder. The millstone is fixed at the output shaft of the decelerator which is the space materials grinded by rollers. The pressurization device which brings pressure for the rollers to grind the materials.
