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 roller bearing. It makes main shaft work stable, and then increase the life of time.

3. Hydraulic lifting mechanism can move away the feed hopper easily, which saves man power during maintenance.

4. Over-vibration indication and warning device is equipped. There will be alarm when vibration surpasses a stipulated figure.

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. Special feed opening structure makes it possible that center feeding,  center feeding & rring feeding changes easily, in order to meet requirement of crushing and reshaping stones.

VSI Sand Making Machine adopts advanced principle of selective crushing and cleavage fracture crushing; impressing enough kinetic energy to materials; Impacting strength will convert kinetic energy to crushing energy. Materials will break through the natural lamination and physical edge. It has the features 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".

1.VSI Sand Making Machine is used for concrete making

Manufactured sand produced by VSI Sand Making Machine is preferred because the cubical particle shape not only contributes more strength to the concrete, but results in further savings because less cement is required. Independent tests have proved that the more cubical the aggregate and the lower the proportion or flaky and elongated particles, the more acceptable the material will be from the mix design aspect. Natural sands have a tendency to have rounded corners and consequently produce a concrete which is not quite as strong as concrete using manufactured sand.

2. VSI Sand Making Machine is used in superpave

The heart of the superpave mixture design system is aggregate properties and volumetric properties. If all the requirements are met, the resulting mix design should have: a strong aggregate skeleton for permanent deformation resistance, sufficient asphalt binder for fatigue and asphalt binder aging resistance, sufficient air voids space to hold plastic properties at bay and prevent permanent deformation. VSI Sand Making Machine can solve all the above problems and VSI Sand Making Machine crushers are well-suited to provide such products.

3. VSI Sand Making Machine can be used in stone shaping

Stones and sand used in road building such as highway and railway track ballast have high demand on shape. So, we must used stone shaping machine after getting crushed stones and sands. VSI Sand Making Machine is the new generation stone shaping equipment designed by our company’s technicians. It dramatically decreases the use cost of the wearing parts. This equipment has the feature of low operation cost, easy maintenance, and low noise.
