Superior Ball Mill from Excellent Quality

 
21-May-2012

 

The hardness of the materials is probably the most essential attribute to consider when choosing which kind of generator to select. Trying to grind a material that is way too hard, for example sand in many types of ball mill, may outcome, either in costly damage to the generator or perhaps an expensive maintenance requirement. The majority of kinds of easily available hammer generators for farming milling aren’t suitable for grinding the majority of types of mineral deposits.

Ball mills are similar in concept to the rod mill but are charged with steel balls in place of the 5 mineral processing talc practical action rods. The ball mill consists of a cylindrical drum, sometimes tapered at one end, and usually has a charge of steel balls ranging in size up to 125mm for larger mills. Product talc size can be as small as 0.005mm, but product size is dependant upon the time the charge spends in the grinding zone and therefore the reduction rate is a function of the throughput.

We all know, ball mill is an important machine in mining machinery industry and widely used in mining , road, building materials, cement, fertilizer , etc. Ball mill is the key equipment to smash after the materials have been broken.

Ball mill can be divided into the following kinds according to different partition methods.

1. Classification according to impact: Light; Heavy

2. Classification according to length: Short mill; Middle mill; Long mill To a service-oriented brand integrity,As the professional manufacturer of complete sets of mining machinery ,like ore beneficiation, Henan Hongxing is always doing the best in products and service.

3. Classification according to mill medium shape : Ball mill,; Rod mill; Great ball mill; Gravel grinding

4. Classification according to unloading way : Tail discharge type mill grind; Middle discharge type mill ; Tail discharge type grinding machine

5. Classification according to the transmission way : Centre drive mill ; Edge transmission mill

6. Other classification : According to process operation, can divided into dry grinding machine, wet grinding machine, intermittent mill and continuous grinding machine.

 

Aside from common ball mills there is a second type of ball mill called Planetary Ball Mill. Planetary ball mills are smaller than common ball mills and mainly used in laboratories for grinding sample material down to very small sizes. A used ball mills consists of at least one grinding jar which is arranged eccentrically on a so-called sun wheel. The direction of movement of the sun wheel is opposite to that of the grinding jars (ratio: 1:-2 or 1:-1 or else). The grinding balls in the grinding jars are subjected to superimposed rotational movements, the so-called Coriolis forces. The difference in speeds between the balls and grinding jars produces an interaction between frictional and impact forces, which releases high dynamic energies. The interplay between these forces produces the high and very effective degree of size reduction of the planetary ball mill.
