Portable crusher is a kind of important crushing equipment, it has been widely used in metallurgy, building materials, hydropower, mining stone, gravel field industries such as washing, grading, impurity removal operations. On the building with sand and gravel, coarse, fine material for building sand washing is still suitable for.

Material from the upper part of the machine vertical fall into the high-speed rotation of the impeller, in high speed under the action of centrifugal force, and the other part of the umbrella shaped flow in impeller of high speed impact around the material, the material in the crash into each other and then in between the impeller and the casing form a vortex, and the number of mutual impact, friction and grinding, discharged from the lower part of the through, after several closed cycle, controlled by sieving equipment meet the requirements of the finished product size, complete washing operation.

In all kinds of crushing equipment the escalation of the situation, some gravel purchasing and processing industry standard began rising. In the construction of gravel on the one hand, is obvious, not only with various aggregate grading standard, also the impurity content of sandstone has strict requirements. In this regard, efficient sand washing has made the tremendous contribution for sand industry machine.
