VSI Crusher Detail Info

• VSI crusher application

  Vsi crusher is widely used in many materials like rock, abrasives, refractories, cement clinker, quartz stone, iron ore, concrete aggregate and so on, and more suit for construction sand, gravel roads to use. According to the customer for many years of production experience, prove that my company's Sand making machine has features of stable of performance ,reasonable structure, high quality, far ahead of other companies of similar products.

• VSI crusher main features and benefits

  • 1. Advanced double-pump oil lubrication system guarantee shaft bearing lower temperature increase, longer life time, more reliable operation.
  • 2. Main shaft is equipped with imported precision rolling bearing. It makes main shaft work stable, lengthen maintenance cycle, increase productivity.
  • 3. Hydraulic lifting mechanism of upper cover can move away the cover easily, which saves man power during maintenance.
  • 4. Over-vibration device is equipped. There will be alarm when vibration surpasses a stipulated figure. It will stop the machine, in order to protect it.
  • 5. Special dust-proof design for main shaft bearing fully avoid dust entering bearing lubrication part, which make sure the machine work normally.
  • 6. Special feed opening structure make it possible that center feeding and ring feeding comes together, in order to meet requirements of different stones. In addition, this equipment can not only crush stone, but also iron.
  • 7. Shape of material-thronging device is better designed, which improve the utilization ratio.

  VSI Crusher Working Principle

  Material from entering hopper into the crushing machine, through the sub-feeder the material is divided into two parts, one part from the sub-feeder middle into the high-speed rotation of the impeller, in the impeller being rapidly accelerated, and the other part in the form of streaming umbrella around the impeller high-speed impact with the crushed material produced in the whole, under the crushing process, the impact of broken material with each other on their own, not in direct contact with the metal components, but with material lining the shocks occur, friction and grinding, which reduces the pollution angle to extend the mechanical wear. Whirl chamber airflow within the clever self-loop, eliminating the dust pollution.
