Latest artificial sand making machines are widely used in all kinds of minerals, which provides the high quality sand and crushed stone aggregate to the high- speed railroad, high-rise construction, municipal administration, water and electricity dam construction, concretes agitation station specially.
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 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 60Â°C or which required being freeze proof and leak proof.
After entering the VSI sand maker, materials are divided into two parts by the distributor. Some enter the high speed spinning impeller through the middle part of the distributor, get speeded up with the accelerated speed of hundred times of gravitational acceleration and thrown out of the three runners evenly spread in the impeller at the speed of 60-70m/s. Then some materials falling around the distributor are crushed and impact into the vortex motion cavity, get rebounded by the material lining, get impact inclined up to the top of the vortex motion cavity, then change the direction of motion and finally form the continuous material curtain with materials launched from the impeller runner. Therefore, materials will suffer two or more times of impact, grinding and crushing in the vortex motion crushing cavity. The crushed materials are discharged from the discharge gate in the bottom.
