タイトルまたは説明

vsi sand maker, this equipment has two types: “rock-on-rock” and “rock-on-iron". Sand yield of “rock-on-iron” type is higher by ****0% than that of “rock-on-rock” type.

Usages:
● It is used for producing building aggregate, concrete, aggregate for road surface and roadbed, asphalt concrete and cement concrete.
● It is also used for sand making and shaping in the field of engineering such as water conservancy, hydroelectric power, high-class highway, high-speed railway, passenger special line, bridge, airport pavement, municipal works and high-rise buildings.
● It is used widely in many industries such as building materials, metallurgy, chemical engineer, mining, refractory materials, cement etc.
● It is used for producing glass raw materials, quartz sand and other high purity materials.

Features and Benefits:
● Simple structure, easy to set up and repair, low cost in operation;
● High production of crushing, has the function of fine crushing and rough grinding;
● Excellent shape of product, mainly the product shape is cubic with small fraction of elongated flaky particle shape, suitable for aggregate shaping, manufactured sand.
● It is little affected by the moisture content of materials, and the content can get up to about 8%.
● It is suitable to crush medium hard and ultra-hard materials. 
● Working noise is lower than *5 decibel, less dust pollution.

Working Principle：
Material falls down into high rolling impeller cavity vertically through the upper part of machine. Under great centrifugal force, it hits and crushes another part of material that distributing around the impeller with umbrella form. After hitting each other, they force a vortex between impeller and shell, and hit each other several times; finally smaller stone comes out, and goes to vibrating screen. Satisfactory material is transported by conveyor belt. However overlarge material will go back to Vertical Shaft Impact Crusher to be re-crushed. Otherwise, output sizes can be also adjusted according to customer’s requirement.
