Generally speaking, there are three simple and direct means to increase ball mill output. The first one is toallocate an impact crusher before the grinding mill. As a result, the mineral stone will be first crushed through the crusher. As the mineral particles become smaller in size, it is easy to reduce the grinding system load. The second one is to make improvement in grinding system.
