As a general-function equipment, it's important to know how to improve ball mill's productivity. A ball mill is a type of grinder used to grind materials into extremely fine powder for use in mineral dressing processes, paints, pyrotechnics, and ceramics. 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.
(1) Add Fine crushing machine before ball mill;
(2) Improve milling system;
(3) Add high-efficient powder concentrator
Three methods mentioned above, any one kind of ball mill can greatly improve yields.Of way, if conditions permit, the factory, then supporting the use ofthe above 3 methods, the effect is the most ultimate, which is grinding system at home and abroad in recent years the trend. Three relationships: the premise of grinding before crushing, grinding powder to make sure that after the election, the fundamental transformation of the roller mill. Milling is premise with fine crushing, powder concentrator after milling guarantees its quality.
Fine crushing makes material size decrease a lot, thus lowering milling load; The increased efficiency of powder concentrator has its advantage: timely and largely selection of end product powder will reduce the frequency of powder remilling. If the efficiency of milling system is low, milling productivity as well as cement quality will be highly affected.
Working Process of Wet Ball Mill
The motor drives the cylinder rotate through deceleration device. When rotating in the cylinder, influenced by friction and centrifugal force, the crushed ores and steel balls are elevated to a certain height by lining board, and fall down because of gravity. Ores are gradually crushed under the influence of impact and grinding. Crushed ores are discharged out of the cylinder. Qualified products go through the spiral classifier while coarse sand was sent back to the ball mill by the joint feeder.
Through material hollow shaft spiral the material is sent to the first mill chamber, in which there are ladder liner or corrugated linings, with steel balls of different specifications in it. When cylinder rotating, centrifugal force will produce steel ball fall down from a certain height, thus impacting and grinding the materials. After coarse grinding in the first chamber, materials enter into the second chamber through a single diaphragm. In this warehouse with flat lining board and steel balls in it, materials are further grinded.
