water pollution toxicity threshold of lead zinc and nickel
Ball mills are used primary for single stage fine grinding, regrinding, and as the second stage in two stage grinding circuits. According to the need of customers, ball mill can be either wet or dry designs. Ball mills have been designed in standard sizes of the final products between 0.074 mm and 0.4 mm in diameter.
SBM delivers the world’s most comprehensive range of Heavy-duty conveyor belts. Base on more than 30 years of experience in development, manufacture and applications know-how, SBM designed the unique belts and belt systems to meet specific end-user requirements for high performance and cost-efficiency.
BWZ Heavy Duty Apron Feeder
BWZ series heavy duty apron feeder designed by SBM is one new type high-efficiency conveying equipments. It absorbs SBM decades years’ experience in designing &manufacturing conveying machines and the advanced technology of the world. This apron feeder is especially suitable for short-distance transmission.
CS Cone Crusher
Comparing with other kinds of crushers, CS Series spring cone crusher is quite excellent in hard material crushing and the final product has good sharp. The innovations like stable lubrication system and excellent sealing system evidently reduce the production cost, helping you to achieve the highest level of profitability.
With the development of mining industry, investors present various requirements of the features of flotation machine. Now there are many kinds of flotation machines, such as agitator flotation machine, pneumatic flotation machine and pneumatic- agitator flotation machine. And different mineral ores have different hydrophilicity, so the final configurations greatly depend on the professional designs.
Hammer crusher designed by SBM fits for producing 0-3MM coarse powder products. This machine adopts theories of traditional crushing machines and grinding mills. It makes up the shortage of common mills, and it is the best choice to produce coarse powder at big capacity.
Compared with the commonly screening and grading equipments, the High-frequency screen adopts higher frequency. As a result, it is able to damage tension force of the pulp surface. Also the fine particles are able to oscillate speedily on the surface of the screen because of the high frequency, and the big expecting minerals are isolated from the pulp easily.
HJ Series Jaw Crusher
By analyzing customers’ requirements and absorbing the world-class advanced technology, SBM developed the HJ series jaw crusher. This machine has larger capacity but the energy consumption is quite low. It is to be the ideal substitute products for old ones.
