vsi impact crusher

Overview of vsi impact crusher:

The SBM

hydraulic vsi impact crusher

is designed by reputed German expert of SBM. This hydraulic vsi crusher is the most advanced impact crusher in modern world, and it introduces high quality roller bearing like Sweden SKF or American TIMKEN, which ensure the smooth running of main unit.VSI crusher integrate three crushing types and can be operated 720 hours continuously. Nowadays, vsi crusher has replaced hammer crusher, roller crusher, roller ball mill etc. and become the mainstream equipment in sand making business.
Note: Vertical shaft impact crusher is called hydraulic vsi crusher for short.

The application of vsi impact crusher:

SBM

hydraulic vsi impact crusher

is widely applied to all kinds of raw materials, such as ores, concrete, cement, fire-proof material, bauxite chamotte, quartz rock, basalt, perlite , glass, etc. Especially for some very hard materials, SBM VSI crusher possesses more advantage than other crusher machine.

Features and benefits of vsi impact crusher:

1) Advanced double pump oil lubrication system, auto-shutdown if no oil, water-cooled cooling system, Motor start up by preheating in winter, all is done to extend the maintenance period.

2) High quality roller bearing from SKF and TIMKEN makes main shaft of the VSI crusher work stable, and extended service life too.

3) Hydraulic lift system can move away cover of the VSI crusher easily, which saves manpower, material, financial resources during maintenance.

4) The brand new automatic protection devices provide the crusher machine with vibrating, oil filtering and warning system. There will be alarm when vibration exceeds the threshold value. The device will stop the rock crusher machine in order to protect it.

5) The special dustproof seal system of the VSI crusher, avoid dust entering bearing lubrication part, so as to ensure the bearings and other transmission system are not abraded.

6) Unique feeding method change between central feeding and central feeding with cascade feeding make "rock on rock” and “rock on iron” possible.

7) Particular material throw head and reasonable materials selection prolong the service time by 40%.

Working principle of vsi impact crusher:

Feed at center:
Materials fall into the hopper and then through the feeding opening in the center enter the high speed rotor which will throw out the materials with high speed. Materials firstly strike those materials that are free falling down. Then, materials strike the materials-liner in the vortex or the impact liner and are rebounded to the top of crushing cavity and then fall down. After that, the falling materials with materials shot from the impeller form a continuous materials curtain. Ultimately, crushed materials will be charged from the discharging opening. Feed both in the center and from sides:

Technical characteristics of vsi impact crusher:

SBM vsi impact crusher integrates three kinds of crushing patterns: material on material, material on iron and falling at sides. Customers can adjust the machines according to their own demand. SBM VSI crusher realizes multiple functions in one machine, which is a big breakthrough in sand making field.
