Flotation machine (also called flotation separator) is applicable for the separation of nonferrous metal and ferrous metal and nonmetal, such as fluorite and talc.
A cement mill is the equipment used to grind the hard, nodular clinker from the cement kiln into the fine grey powder that is cement.
The sand washer is a kind of highly efficient sand washing plant, taking the advanced techniques and the domestic physical conditions together into consideration.
Cement milling and gypsum dehydration Because the cement gets hot due to the heat generated by grinding gypsum can be partly dehydrated forming hemihydrate or plaster of Paris 2CaSO 4 H 2 O On further heating hemihydrate dehydrates further to a form of calcium sulfate known as soluble anhydrite CaSO 4
