Quarry river stone sand crusher machine manufacturer

Rotor centrifugal sand maker is one kind of high efficient sand making machine that equipment with vertical shaft. This machine is widely used in the basalt, limestone, river gravel, granite and other types of materials processing and shaping broken. The production ability of this machine is from 30t/h to 400t/h. Rotor centrifugal sand maker is suitable for the crushing process of mineral material and the hardness material. Due to its special structure, this machine has good performance in many kinds of sand production lines.

Features:

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, increases 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 makes it possible that center feeding and ring feeding comes together, in order to meet requirement of different stones. In addition, this equipment can not only crush stone, but also iron.

7. Shape of material-through device is better designed, which improve the utilization ratio.

Application:

VSI crushers are very suitable for making sands for building and construction, such as expressway and railway building, hydropower station construction, bridge and tunnel building, concrete batching plant, etc. When it comes to the shaping of gravels used in concrete aggregates, the B Series VSI crusher is the best choice, especially for the strength of concrete above 60°C or which required being freeze proof and leak proof.

Working Principle:

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”.
