Series VSI sand making machine, is the second generation sand making machine we produced, mainly used for the production of the artificial sand, crushing ore and construction waste. It is based on our engineers' many years' R&D, absorbing the advanced technique overseas,with international advanced stage.

It is of high efficient energy-saving crusher,Its good performance plays a Irreplaceable role in fine crushing of all kinds of ores. This crusher is widely used in crushing and reshaping of metallic and non-metallic ore, building materials, artificial sand and all kinds of metallurgical slags.

Working Principle

VSI crusher adopts advanced principle of selective crushing and cleavage fracture crushing;Impressing enough kinetic energy to materials;Impacting Stength will convert kinetic energy to crushing energy;materials will break through the natural lamination and physical edge. It has the featuers of better shape of final products, but less cost. This machine can realize two working principles' conversion with "crushing between materials" and "crushing between materials and liners".

VSI Vertical Shaft Impact Crusher Features

1. Advanced double-pump oil lubrication system guarantees the shaft bearing lower temperature increase, longer life time, more reliable operation. It prolongs the maintenance period of the machine.
2. Main shaft is equipped with imported precision rolling bearing. It makes main shaft work stable, lengthen maintenance cycle, increases productivity.
3. Hydraulic lifting mechanism can move away the feed hopper 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 avoids dust entering bearing lubrication part, which will make sure the machine work normally.
6. Shape of material-through device is better designed, which improve the utilization ratio.
7. Environmental protection-Sand making machine id low noise and no pollution. Unique air from the circulatory system which greatly reduces the amount of outside ventilation to reduce dust, environmentally friendly. VSI sandmaking machine also set aside and install a variety of specifications for dust removal equipment.
