Working Principles. Like all vibrating feeders, an electromagnetic vibrating feeder moves product by making the feeder tray vibrate. The product sits in the tray. When the tray vibrates, the product moves in a series of small hops. This series of hops combine to create the constant motion of the product. The direction of movement is determined ...

To prevent coal entering in to the Gear case, an air sealing system is provided. Hot primary air for drying and carrying pulverized coal, enters through insulated Mill side and Liner Assembly. Tramp Iron, pyrites and stones coming in the mill with raw coal move out of the bowl and being heavy, fall into the mill side and linear assembly.

2. Difference in working principle Dry grinding. Dry grinding means that when the ore is ground into required particle size, the powder will be brought out from the dry ball mill by airflow. Dry grinding process: 1 The material from the feeding device is evenly fed into the first bin of ball mill by the hollow shaft spiral. This bin has stepped ...

The principle of attrition mills is that the material is rubbed between two surfaces. Both pressure and frictional forces are generated. The extent to which either of these forces predominates depends on the pressure with which both surfaces are held together and the difference in the speed of rotation of the surfaces.

The modern coal mill classifier, however, often has an impeller mounted close to the exit of the mill chamber. The impeller is a cage with a set of blades installed around its outer ring. It introduces a secondary classification by the collision effect in addition to the primary classification by centrifugal force [[11], [12], [13]].

Ball mill principle work on Impact and Attrition. Both are responsible for size reduction, rapidly moving balls are used for reducing the size of brittle materials. Impact: Impact mean pressure exerted by two heavy objects. Attrition: Reduced the size of the materials when they colloid by heavy weight (Ball).

The ball mill consists of a metal cylinder and a ball. The working principle is that when the cylinder is rotated, the grinding body (ball) and the object to be polished (material) installed in the cylinder are rotated by the cylinder under the action of friction and centrifugal force. At a certain height, it will automatically fall and impact ...

Working Principle of RMG: Rapid mixture granulator works on agitation and tumbling. The impeller is responsible for uniformly mixing wet granules, and the chopper helps in breaking or reducing particle size. At the starting process or during binder addition, the impeller and chopper generally operate at low speed.

To summarize the coal mill controls, they may be divided basically into two major categories:. 1. To control the quality of coal being 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.
