VSI sand maker:, 1.600t/h througput, 2.Feed Max 60mm, 3.saving cost 30%, 4.38 years experience supplier - details see: https://www.machineto.com/higher-crushing-ratio-vsi-sand-maker-with-iso-ce-quality-approved-10083004

1.Characteristics of VSI sand maker :

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 requriement of different stones. In addition, this equipment can not only crush stone, but also iron.

7. Shape of material-throughing device is better designed, which improve the utilization ratio. Usage: VSI Sand Making Machine is widely used for artificial sand, in metal and non-metal ores, cement, refractory material, bauxite, silicon carbide, glass material, building material.

2.Working Principle of VSI sand maker :

(1) Center Feeding:Raw material falls down into feed hopper, then enter into impellor through central entrance hole. It is accelarated in high-speed impellor, then is thrown out at speed of 60-75m/s. When it hits impact plate, it is crushed. Final products come downwards though outlet.

(2) Ring Feeding: Raw material falls down into feed hopper, then through ring, it is divided into two divisions by material-deviding plate. One enters into impellor through the center of material-deviding plate. The other falls down from outside of material-deviding plate. Material, which is thrown out by impellor at speed of 60-75m/s, hits material coming down from outside of material-deviding plate. In this way, material is crushed.
