The screening machine is an important machine in mineral industry, which adopts specific method to separate the mixed particles into two groups, one group is smaller than the sieve pore, and the other group is larger than the sieve pore. It is often used in conjunction with crushing machine in preparation stage, including pre-screening and check-screening to increase the processing capacity of crusher and avoid the overcrushing of ores. At the same time, it is used to screen the materials in dehydration and de-medium step, as well as in ore grading and refilling step. In order to achieve the required processing capacity and get the high screening efficiency, the sieve surface must be big and the materials that smaller than the sieve pore pass through the mesh quickly. In this process, in addition to the characteristics of material itself, the key lies in the type of ore screening machine. What kinds of ore screening machine are available?

Stationary screen, drum screen, vibrating screen, linear vibrating screen and circular vibrating screen.
