At present, the annual output of medium and large sand and gravel production lines can reach more than 1000 tons. The configuration of the whole production line is as follows:

(1) coarse crushing -E crushing: this is necessary for any stone to be processed. Jaw crusher can be used for primary crushing, and the next step can be carried out after crushing to a certain particle size.

(2) Medium crushing-cone crushing: After the initial crushing, we need to use a cone crusher to medium crush the coarse crushing materials again.

(3) Screening-vibrating screen: At this time, we need to screen the materials with vibrating screen, and the unqualified materials need to be crushed again, and then the qualified products are obtained for the next step.

(4) Fine crushing-sand making machine: the screened materials are sent to a sand making machine by a conveyor for sand making, that is, fine crushing treatment.

(5) Secondary screening: the crushed materials are screened by a vibrating screen to obtain products with three specifications, and users can choose according to their needs.
