With high silicon content and abrasion resistance, Basalt is hard and tough material , and difficult to be broken in actual crushing operation. In the design of crushing process, priority should be given to crushers with lamination crushing principle, to reduce the loss of wear-resistant parts.

The equipment combination (four section type) of basalt stone crushing production line is generally as follows:

(1) Feeding: vibrating feeder.

(2) Coarse crushing: jaw crusher with feed size of 1500-500mm, crushing to 400-125mm.

(3) Medium crushing: cone crusher or fine jaw crusher with feed size of 400-125mm and crushing to 100-50mm.

(4) Fine crushing: impact crusher (or vertical impact crusher), feeding particle size of 100-50mm, crushing to 32-5mm.

(5) Screening + dedusting: vibrating screen + dry deduster.

(6) Shaping: impact crusher or shaping crusher (after screening the fine crushed stones, the qualified ones will be sent to the storage bin through the belt conveyor, and the materials with unqualified particle size and shape will be returned to the impact crusher or vertical impact crusher for further processing and shaping).

(7) Screening + dedusting: vibrating screen + dry deduster.

(8) Conveying material: belt conveyor.

(9) In order to reduce dust and soil, the coarse crushed stone is transported to the medium crushing crusher by the vibration feeder, and the subsequent stone conveying is completed by the belt conveyor.

 

Whether dedusting equipment is installed depends on the cleanliness of the gravel (whether the mud content is qualified) and whether there is a water washing process. If there is a water washing process, it is not necessary to install the dust removal equipment.
