VSI crushers namely Vertical Shaft Impact Crusher are widely applied in various quarries, mines and construction sites, especially for road & building, hydropower station, bridge and tunnel for crushing and shaping aggregates and sands.

Vertical Shaft Impact Crusher is highly recommended when it comes to the shaping of gravels used in high strength concrete. In the fine crushing section, VSI Crusher is the substitute of impact crusher, and it is much better in terms of main performance indexes.

VSI crusher is a high-efficiency rock crushing equipment with home and international leading level. It is widely used for crushing of hard and brittle materials, such as rock, grinding material, refractory material, cement clinker, quartzite, iron ore and concrete aggregate and especially suitable for sand making for construction and road paving as sand maker. VSI crushers are especially very excellent crushing machines for shaping purpose.

VSI Crushers Working Principle

Raw material falls down into feed hopper, and then enters rotor through central entrance hole. It is accelerated in high-speed rotor, and then is thrown out at speed of 60-75m/s. When hitting anvil, it is crushed. Final products come downwards though outlet.

Raw material falls down into feed hopper, and then through ring, it is divided into two parts by material-dividing plate. One enters into rotor through the center of material-dividing plate. The other falls down from outside of material-dividing plate. Material, which is thrown out by rotor at speed of 60-75m/s, hits material coming down from outside of material-dividing plate. In this way, material is crushed.

VSI Crushers (Sand Maker)

VSI crusher is a new type rock crushing equipment and is used for substituting roller and ball mill

VSI crusher is simple and stable for operation

VSI crusher is low energy consumption, high output and big reduction ratio

VSI crusher is small volume, convenient operation, installation and maintenance

VSI crusher has cubical shape with little pollution

During the process, the stone rock can form a protective bottom layer which makes the equipment more durable

Advanced lubrication system guarantees shaft bearing lower temperature increase, longer life time, more reliable operation

VSI Crusher main shaft is equipped with imported precision rolling bearing. It makes main shaft work stable, lengthen maintenance cycle, increase productivity

VSI Crusher adopts hydraulic lifting mechanism of upper cover. it can move away the cover easily, which saves man power during maintenance.

Special dust-proof design for main shaft bearing fully avoid dust entering bearing lubrication part, which make sure the machine work normally

Special feed opening structure makes it possible that center feeding and ring feeding comes together, in order to meet requirements of different stones. In addition, this equipment can crusher not only stone, but also iron

※ Capacities are based upon ordinary limestone not containing wet fine particles. Ton=1,000 kg.

* The above capability is applied in case the aggregates, as a specific gravity of
1.6, are supplied consistently.
* The treatment capability depends on the moist and injection material)
