In the road and bridge project, there are great amount of stone materials for concrete material making with the content of 80%. But the crushing of stone materials are needed the grading, dewatering, and foreign material removing, then we configure the crushing and screening machines.

In the crushing and screening machine design, Dingli mining machine has the features of suitable machine configuration and compact machine layout for less land occupation, higher investment cost, better stone material quality, and less stone powder. Dingli main mining machines of heavy hammer crusher machine is the mining crushing machine special for the crushing of medium hardness materials of limestone with the advantages of average material shape and cubic materials size. In the material screening process, we adopt the circular vibrating screen with better screen shape with the unique machine structure design and operation ways for higher production efficiency.

In the material crushing and screening process, we generally adopt the design model of closed type. That is means material with qualified material size will be conveyed into the finished material stockpile after crushing. Materials with unqualified material size will be conveyed into stone machine for repeated crushing for higher production efficiency, lower production capacity, average material size, and better material quality.

Crushing machines and screening machine configured by Dingli is used for the operated of all kinds of stone crushing material and sand for the building of road, construction, water conservancy, mining industry, and port. We provide the full service with before, on, and after sale and configuration production line with customer demand, and the reasonable and economical production line.
