VSI series impactors are represented in Model A and Model B,among them,Model A with a "Rock on A Anvil" crushing chamber is mainly used for low abrasive rock,Model B with a “Rock on Rock”mainly used for abrasive rock.Mode A and Model B can be converted into each other by replacing crushing chamber.VSI series are featured in high reliability,less maintenance and economic operation cost over competitors,all the benefits are from cascade feeding,deep rotor,full feed flow centralization,inner air flow cycling,heavy duty hearings and oil lubrication systems.
VSI sand making machine can be widely used in crushing sand metal, nonmetal and a variety of building materials, sand and gravel aggregates, slag and other raw materials for raw materials in the following Mohs hardness of 9 degrees, VSI Sand Making Machine can be divided into the new into two sand structure, namely two rock stone blacksmith and stone, rock stone was at work when the collision friction material with each other through broken stone blacksmith was hit by a liner on the stones carried on stone crushing, VSI New Sand using these two methods for shaping the raw material sand, according to the needs of actual operating conditions corresponding system of sand degrees.
Stone from the upper part of the machine directly into the high-speed rotation of the turntable, under the action of high-speed centrifugal force, and another part of the umbrella way to split the turntable around the target stone to produce high-speed impact and high-density crushing, stone hit each other, But also in the turntable and the formation of eddy motion between the chassis caused by repeated combat, friction, crushing, from the lower part of the discharge. Forming a closed loop multiple times, controlled by the screening device to achieve the required particle size.
Stones enter the crusher by the vibrating feed and are divided to two components. Some enter the high speed spinning impellor by means of the distributor plus the accelerated speed might be a hundred times of the gravitational acceleration.
Then the components are thrown out from three runners in the speed of 60-70m/s and effect the falling materials in the distributor.
Then they come for the lining of the inner cavity and get bounced by the material liner for the upper finish with the whirling motion cavity.
Then they transform the direction to move down. The materials cast in the impellor type a continuous material curtain. In this case, the supplies can knowledge two or a lot more occasions of impacting and grinding processes.
The crushed supplies are discharged in the bottom hole.
Forming a closed circuit with all the circulation screening system, the vibrating feeder can deal with the components as fine as 20 meshes inside 3 circulations.
Within the complete crushing procedure, the materials hit each and every other without the need of touching the metal elements directly.
They meet the material lining so as to decrease the pollution and prolong the service life in the machine. The sophisticated air flow in the whirling motion cavity can properly lessen the dust pollution.
