Verticalrollermills(VRM) can replace ballmillsor tubemillsused for preparingcoal. Today VRMs with capacities up to 50 tph are the dominant technology forcoalgrinding. According to MIIT, grinding media wear in a VRM will only be 5 to 10 g/ton ofcoalpowder, as compared to 100 g/ton ofcoalpowder in a ballmill.

Vertical roller millis a popularpulverized coal millin recent years. Working Principle The working principle ofvertical millis as follows: the material is fed into themillthrough the inlet on the top center of themilland falls on the grinding plate, and the grinding rollers which are driven by the rotation of the grinding plate will crush the material.

The raw coal enters the vertical mill bin: The reducer drives the millstone to rotate, and the raw coal enters into the mill through the feed port, scattering on the millstone. Grinding the raw coal: Due to the effect of hydraulic pressure, the extrusion between the grinding rollers and the millstone causes the big pieces of raw coal crushed.
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.
Coal vertical millproduct description. 1. The rawcoalis sieved from the rawcoalstorage yard through a grid screen and then falls onto the belt conveyor. After the iron is removed by the electromagnetic separator, the belt conveyor sends the rawcoalto the rawcoalbunker for storage. 2. After the pulverizing system has been started, open ...
If thecoalis not sufficiently dried, it will be adsorbed inside thevertical milland the pulverizedcoalpipe, which will block the pulverizedcoalpipe or cause thevertical milland the pulverizedcoalpipe to catch fire. Solution: Reduce thecoalfeed rate, maintain the outlet temperature, and re-check the ventilation control system. ...
To summarize thecoal millcontrols, they may be divided basically into two major categories:. 1. To control the quality ofcoalbeing sent to the burners located on the furnace walls. The word quality here means the temperature and fineness of the PF. The set temperature values are dependent on the percentage of volatile matter that exists in the main fuel.

Roller Mils are directly driven bevel-wheel planetary gears or bevel cylindrical gear units. The gear unit represents an almost integral component of themill. The output flange of the gear unit is rigidly connected with the grinding table. In addition to transmitting the torque ,the gear unit also has capability to take up the reaction forces from the the griding force of the mils rollers.
Ballmillsandverticalrollermillsare used for many grinding applications in cement production: raw meal grinding,coaland pet coke, and finish cement grinding. Improving the competences of the team plays a key role in the optimal utilisation of the grinding installation in your cement plant.
