The SAG Mill has four output slots; recipes can have 1-4 different outputs, with different chances of obtaining those outputs. Uniquely, the SAG Mill can use Grinding Balls made from various materials to increase energy efficiency (resulting in higher processing speed), increase bonus output chances, and add a chance to double all output.
Sand-returning ratio is the ratio between the amount of sand return of ball mill and the feeding capacity of raw ore, which can directly affect the productivity of the ball mill. One way to improve the sand-returning ratio is to increase the feeding capacity of raw ore, another way is to reduce the shaft height of the spiral classifier.
So how to improve the hourly output of the hammer crusher? First, check whether the parts of the mining stone hammer crusher is worn out. Especially the hammerhead must be checked regularly, if the wear is serious, it will directly affect the hourly output of the rock hammer crusher. The second is the feed size of the material.
The low grinding efficiency of the ball mill, low processing capacity, high production energy consumption, and unstable product fineness are the problems that most concentrators will encounter. How to effectively improve the grinding efficiency of the ball mill is an important issue.
Generally speaking, there are three simple and direct means to increase ball mill output. The first one is to allocate 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.
