Mineral processing Practical Action Technical Brief
Table 2: Mohs scale of hardness In general the harder the material the more specialised and expensive the type of mill used has to be. In addition if a particular mill can be used over a range of hardness scales the harder the material the lower the throughput for a given size requirement.
Smart Mining Machinery provides you the Mobile Crusher
grinding mills are designed by engineer combining clients 39 requirement and practical situation. The grinding mill is widely applied in glass rubber farm chemical enamel oil paint phosphatic fertilizer and papermaking industry and it could process material whose Moh 39s hardness is less than 9.3 moisture is less than 6 such

The laboratory size hammer mill was fabri ed from locally available materials for crushing of materials such as calcite dolomite limestone granite and other materials of medium hardness.
Our materials handling capabilities range from individual machines to the design and construction of complete handling facilities for port terminals and stockyards. thyssenkrupp solutions are proven and soughtafter the world over for example in the mining cement chemicals and fertilizer sectors as well as in coalfired power plants
Economic And Practical Hammer Crusher For Hardness Materials
Hammer is the main wear parts for shredder plant hammer mill and hammer crusher. The standard material for the hammer is manganese steel. However manganese steel hammer does not have a good working life in crushing some material. Such as In the thermal power industry the Mn14 hammer can only operate for than 100 hours on site.

Hammer mill configuration. The three basic types of hammer designs are: The stirrup or LFS hammer the swing bar hammer and the rigid bar hammer. The stirrup hammer has the most surface area and is used at high speeds to produce the finest particle sizes. The swing bar hammer is used on materials that do not respond well to impact.
MINERAL PROCESSING MILLING
Hardness of minerals is expressed on Mohs scale a numerical index ranging from 1 for talc the softest mineral to 10 for diamond the hardest known material . Table 2 below shows Mohs scale of hardness. Hardness No. Mineral example Common practical test 1 Talc or graphite Marks paper like a pencil 2 Rock salt or gypsum
