The grinding process in ball mills and vertical roller mills is fundamentally different [15]. Following are advantages of VRM over Ball Mills with reference to these issues: • Strong drying ability Inlet hot air from Kiln can dry materials with 20% water content. (max moisture 20% vs. 3% in ball mill) [15], [16]. •

In most sites a ball mill gets used for grinding, to produce fine particles, and a (hydro) cyclone gets used for classification, to separate the fine particles from larger particles. The main objectives when controlling the grinding circuit are to maximize the throughput and to decrease the variability of product size and % solids.

from a central outlet at the top. The rotatory flow within the cyclone separator causes the particles to be acted on by centrifugal force. The solids are thrown out to the walls, thereafter it falls to the conical base and discharged out through solids outlet. Uses Cyclone separators are used to separate the suspension of a solid in a gas (air).

Description. A Spiral Classifier is a machine that is primarily used to classify the slimes (fines) from a coarser, sandy sized material. It has an inclined trough with one or two spirals revolving slowly and free from touching the sides or bottom of the tank. The motion of the spiral creates Pool Hindered Settling in the bottom pool area ...

How It Works Cyclone separators work much like a centrifuge, but with a continuous feed of dirty air. In a cyclone separator, dirty flue gas is fed into a chamber. The inside of the chamber creates a spiral vortex, similar to a tornado. This spiral formation and the separation is shown in Figure 2.

cyclone is a device that uses centrifugal forces to classify solid particles, in a liquid stream, by size and/or density. What does a Cyclone do? If a cyclone is fed with a sand and water mixture containing a range of particle sizes, most of the fine sand will report to the overflow (the top of the cyclone), together with most of the water.
