however, it is now commonly agreed and accepted that the work done by any ball mill depends directly upon the power input; the maximum power input into any ball or rod mill depends upon weight of grinding charge, mill speed, and liner design.
factors affecting ball mill grinding efficiency. the same source of synergy found in turners optimized load principle can also be applied to ball milling through suitable application of grinding mechanisms in conjunction with the other previously described factors that effect ball mill efficiency.
in gold mining process, we usually use belt conveyor to convey seven trust gold ore to the jaw crusher and vibrating screen, after crushing and screening, the suitable particles are fed into ball mill to grind. we usually grind it to 200 mesh or 325 mesh. then the gold fine will be fed into double spiral classifier. the purpose is to separate the fine particle and coarse particle.
ball mills. greater efficiency in grinding is now obtained by adding a classifier to the first stage so as to convert it into a closed circuit. the overflow of the primary classifier passes to the second stage and the overflow of the secondary classifier is the finished product of the grinding section.
after materials crushed to the desired particle size, enter into the storage hopper by the elevator, and then through vibrating feeder enter into grinding chamber of raymond mill uniform continuously.
ball mill grinding machine is a kind of horizontal drum-type grinding mill with external gear and double bins. materials goes evenly through quill shaft in feeding device into the first bin, which has ladder lining or ripple lining with steel balls in different specifications.steel balls are taken to a certain height by centrifugal force from
ball mill: this machine works in both dry and wet methods intermittently, to mill, mix and discharge materials such as feldspar, quartz and clay. the slurry can pass through 1000 sieve pore. it's a kind of super fine grinding mill, so the feed material should be in medium size to get best grinding efficiency and economic profit. ball mill working principle: the ball mill is a horizontal rotating device transmitted by the outer gear.
gold ore mobile crusher can eliminate the obstacles of the crushing places and circumstances, and offer the high efficient and low cost project plants for the client to the client, gold mobile cursher is the best choice as a gold mining machine ball mill for gold mining. new designed ball mill gold ore mines manufacturer, view ,
ball mill liner design. rubber liners of the integral molded design follow the cast metal design. if using the replaceable lifter bar design in either metal or rubber the number of lifters should be about 3.3 d in meters for d in feet* divide 3.3 d by 3.3 with the lifter height above the liners about twice the liner thickness.
