The structure of Ceramic Ball Mill: Ceramic Ball Mill is mainly composed of a driving device, a cylinder body device, feeding device, discharging device and an electrical control device.Ceramic Ball Mill load is large, the power consumption is large, so the ceramic ball mill is usually used between 1 and 2 several hundred watts of power electric motor through a hydraulic coupler to drive the hardened gear reducer, and then by a pair of gears or belt drive the cylinder to rotate, thereby achieving the effect of grinding material.
Ceramic ball mill working principle: the ball mill by feeding department, discharging part, turning part, a transmission part (reducer, small transmission gear, motors, electrical control) and other major parts.Ceramic ball mill has a horizontal cylinder, cylinder by a separator (drill has many small hole sieve) into 3 ~ 4 grinding cavity, each grinding cavity is provided with a certain shape and size of the grinding body, cylinder rotates, the material and grinding body in the friction force and the centrifugal force of cylinder body is lifted to a certain height, then under the action of gravity along a parabolic trajectory falling impact and grind the bottom of the cylinder body is another part of the material, and to produce the axial movement makes the material grinding and mixing.
Ceramic ball mill which belongs to the low-speed heavy load equipment, large loading capacity, starting torque is big, therefore ceramic ball mill is usually used additional starting motor shock initiation or soft starter to start, impact, and started after the completion of operation when the desired torque is reduced, so the energy saving aspect to have the very big space.

Direct Preferential Flotation
Definition of this method is: separate various helpful minerals in proper order. With its feature of high flexibility, it can adapt the change of ore grade, especially for sulphide ore of high grade. Xilin, Fankou, Lechang lead-zinc dressing plant of our country, and Laisvall lead-zinc dressing plant of Sweden all adopt this method.
Combined Flotation Flowsheet
Firstly, get mixed concentrate through the emersion of all useful minerals in ores; secondly, separate various helpful minerals in sequence from mixed concentrate. These two steps together are called part of amalgamate flotation Flowsheet. This process is suitable for treat raw ores of complex structure, fine embedded grains, and low content of sulfide mineral, which are in close symbiosis relationship. Because this process can simplify process, reduce ores’ over grinding, so as to benefit separation. Almarc Lead-zinc plant of former Soviet Union adopts preferential flotation this process. By using this process, we can get higher index than preferential flotation improve 10% of lead concentrate ore grade and 4.5% of zinc concentrate ore grade, raise the rate of multipurpose utilization from 75.4% to 83.7%, and double labor productivity. Qingchengzi zinc-lead ore dressing plant and Xiaotieshan copper ore dressing plant of our country adopt this process.
Part of Amalgamate Flotation Flowsheet
We can get mixed concentrate by the emersion of two useful minerals in ores together, then separate single concentrate from the mixed concentrate. The two stages together are called part of amalgamate flotation Flowsheet, which is the most widely used process in production. It is quite economical to adopt this process when raw ores contain low-grade nitrogen, copper-lead, copper-zinc, and lead-zinc.
Iso-flotability Flotation Process
According to minerals’ flotability in ores, mineral assemblages of good, medium and worse flotability are separated through flotation separation. Secondly, different helpful minerals are selected out from all mixed concentrates, which is called iso-flotability flotation process. For example, Huangshapinng lead-zinc ore dressing plant of our country, and Zheskaz of former Soviet Union both adopt this process. beneficiation,Mineral Processing,rotary kiln http://www.dryballmill.com
