Sand maker

Sand making machine

ZENITH VSI sand making machine or VSI sand maker is a type of sand crusher suitable for the crushing of soft , hard and extremely hard material and reshape of those products, which can be used in some areas of ores, cement, refractory, aluminum where the soil clinker, emery, glass raw materials, mechanisms built stone gold slag, especially on the silicon carbide, silicon carbide, sintered bauxite, sand contour hard, special hard and corrosion-resistant materials whose output is higher than other types of crushers yield efficacy.

VSI sand making machine working principle

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

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

Characteristics of sand making machine

    1. Components enter the crusher through the feed hopper and are divided to two components. Some enter the high speed spinning impellor through the distributor plus the accelerated speed may be a hundred occasions in the gravitational acceleration.

    2. Then the materials are thrown out from three runners in the speed of 60-70m/s and effect the falling supplies from the distributor.

    3. Then they come towards the lining of the inner cavity and get bounced by the material liner for the upper finish in the whirling motion cavity.

    4. Then they change the path to move down. The supplies cast from the impellor form a continuous material curtain. In this case, the materials can experience two or far more instances of impacting and grinding processes. The crushed components are discharged from the bottom hole with the Sand Crushing machine.

    5. Forming a closed circuit with all the circulation screening method, the vibrating feeder can handle the components as fine as 20 meshes within three circulations.

    6. In the whole crushing course of action, the supplies hit one another devoid of touching the metal components straight. They meet the material lining in order to lessen the pollution and prolong the service life on the sand making machine. The sophisticated air flow within the whirling motion cavity can efficiently lessen the dust pollution.

The Application of sand making machine:

1. The sand crusher can crush river pebbles, rocks (limestone, granite, basalt, diabase, and esite), ore tailings, the artificial sand stone chips.

2. Production of construction aggregate, Highway fabric, cushion material, asphalt concrete and cement concrete aggregate.

3. Production of water conservancy and hydropower engineering, highway, highways, high-speed rail passenger line, bridges, airport runways, municipal engineering, high-rise building mechanisms sand and stone shaping.

4. Material crushing grinding of the mining areas of front-end crushing process, building materials, metallurgy, chemical, mining, refractory, cement, abrasive industry.

5. High abrasive and secondary disintegration broken, thermal power, metallurgy industry, in addition to sulfur, slag, construction waste crushing and other environmental projects.

6. Glass, quartz sand and other high purity materials production.

Sand making plant

  • Sand making machine , operating procedures and steps are:
  • (1). open system sand machine (sand making machine) before check the vortex chamber observe whether door is shut, to prevent the material from the vortex chamber to observe rushed out of the door, produce risk.
  • (2). check the system Sand Crushing machine impeller direction of rotation, from the mouth direction. Impeller should be counterclockwise rotation, otherwise the motor wiring should be adjusted.
  • (3). the sand making machine and conveyor equipment startup sequence is: discharge to crusher, feeding. Crusher must be started light, wait for after crusher operating normally, feeding direction; In contrast to the boot order stop order.
  • (4). the Sand making machine into the material particles in strict accordance with the specified requirements, is greater than the specified material into the crusher is forbidden, otherwise, will cause the impeller imbalance and excessive wear of impeller base to jam impeller passage and center into the feed tube, make the crusher can not work normally, found a large piece of material should be ruled out in time.
  • sand-making-plant
  • (5). Sand making machine stop moving, should stop feeding in time, otherwise, will cause the crushing impeller, burning motor.
  • (6). Sand making machine feeding strive to continuous uniform. All landowners system Sand Crushing operation process, can not have violent vibration and abnormal noise, otherwise, should stop it for checking. End system sand machine lubrication, lubrication for dry oil lubricating way, using mobil automotive embellish lipid super, add quantity for 1/2 - two-thirds of the bearing cavity, crusher each work, add right amount of grease, after working several class, open the main bearing of main bearing cleaning, replacement of bearing when necessary.
