What are the common crushing equipment for sand and gravel plant

Large stone crushed into sand and gravel aggregate, which is widely used in highways, railroads, bridges and other infrastructure industries, and sand and gravel aggregate used in different places on the stone specifications are different, the general stone sand requirements of particle size less than 4.75 mm, the sand is graded according to the fineness modulus.

1. Jaw crusher is the necessary coarse crushing equipment in the sand and gravel production line. The core construction parts are jaw plate and frame, two jaw plate crushes the material by simulating the chewing action of animals, with simple structure and large crushing ratio, which can reduce the particle size of the large material to below 400mm, and provide the qualified material of particle size for the subsequent medium crushing process.

Feeding size: 120-1500mm.

Production capacity: 1-1200t/h. 

2. Cone Crusher. Cone crusher adopts the principle of laminar crushing, the crushing cavity and crushing frequency are skillfully combined, there is no crushing blind area, the phenomenon of over-crushing is less, and the discharged finished product is mostly cubic, which largely reduces the generation of needle-flake materials and fine powder. It is divided into three types: coarse crushing, medium crushing and fine crushing.

Feed size: 65-300mm.

Finished product size: 3-60mm.

Production capacity: 12-1000t/h.

3. Impact sand making machine. Impact crusher adopts “stone to stone” and “stone to iron” mixing to realize crushing and sand making, can realize shaping and processing at the same time of sand making on gravel raw materials, the sand is good, cubic, no tension and cracks, fineness modulus is adjustable, gradation is reasonable, and accompanied by a small amount of stone powder.

Feed size: 30-60mm.

Finished granularity: less than 4.75mm.

Processing capacity: 12-650t/h.

At present, the market price of a stone crusher is about several hundred thousand to millions of dollars, because there are many types of stone crusher models, plus stone crusher manufacturers are often more, so its specific price is not too good to determine.
