New generation shanghai mining jaw crusher, pew series jaw crusher is born with innovative significance. It is newly designed and improved by our experts on basis of their more than 20 years' crusher manufacturing and design experience. The unique design concept makes this series shanghai mining jaw crusher achieve perfect combination between crushing efficiency and operating cost. Meanwhile, it has a wide range of application, particularly is suitable for crushing hard rock, such as basalt, river pebbles.
shanghai mining jaw crusher working principle:
The structure of shanghai mining jaw crusher: main frame, eccentric shaft, a large belt pulley, fly wheel, swing jaw, side guard plate, toggle plate, Rear bracket, adjust gap screw, reset spring, and fixed jaw and swing jaw board etc., and the toggle plate also plays a role of protection.
The motor transmits power through belt and belt pulley, drives the swing jaw surround the eccentric shaft do periodic motion. The angle between toggle plate and swing jaw increases when swing jaw moves up., which makes the moving jaw get closes to the fixed jaw.
At the same time the material is squeezed, rubbing, grinding and other multiple broken. The angle of Jaw Crusher between toggle plate and swing jaw decreases when swing jaw moves down, the moving jaw of Jaw Crusher moves away from fixed jaw by the pulling of rod and spring, the products after crushing will be discharged from the outlet of Jaw Crusher.
shanghai mining jaw crusher structure and application:
shanghai mining jaw crusher is widely used for medium crushing various ores and bulk materials in mining, smelting, building materials, highway, railway, water, chemical industry and other industries. The crushed materials are of a compressive strength less than 320MPa. Jaw crusher has the characteristics of big crushing ratio, uniform finished product size, simple structure, reliable work, convenient repair and low operating costs. Then how are jaw crushers used in the sand making line? please see the following picture:
shanghai mining jaw crusher for sand making line:
In the process of sand making production line, raw materials are conveyed to the jaw crusher for a coarse crushing by the belt conveyor; after the rough crushing, the materials are conveyed into a fine jaw crusher for a further crushing, then the fine crushed materials are conveyed into the vibrating screen for a separation which classified the materials into two kinds of stone, one part that meet the size of feeding mechanism of sand gravel base sand will feed into the sand making machine, another part will feed back again into the fine jaw crusher for a third crushing, the size of fineness can be adjusted according to customer demand. Fine jaw crusher are the improved simple pendulum or compound pendulum shanghai mining jaw crusher, which applys a plurality of the dynamic jaws and a plurality of eccentric shaft structures, which will reduce the loads of the machine when the jaw crusher running. And it is easy to start, smooth to run and with low energy consumption.
