construction sand making machinery / building sand making machine

brief introduction

sand making machine is the latest product of authoritative experts from Germany, connecting with Chinese present working conditions. It’s the high—efficiency sand making equipment with advanced world levels in our country. It is the preferred equipment for artificial sand making and stone reshaping industry.It specially provides the best material for the highway,railway,high-rise buildings,municipal works,hydro-electric dam and concrete mixing station. It ranks first among similar products with its excellent cost performance and reliability.

Application Range

1. sand making machine is used for Pebble,rock( the limestone, granite, basalt, aluminum, andesite, etc.), ore tailings, attle artificial sand production.

2. sand making machine has been used in Building aggregate, highway, cushion, asphalt concrete and cement aggregate production.

3.Sand making production and stone reshaping production in water conservancy and hydropower engineering field,highway,railway,bridge,passenger line,air new generation sand making machine port runway,municipal engineering and high-rise buildings.

4.The grinding anterior finely process of mining areas. Building materials,mining,metallurgy, chemical industry,cement,abrasive,refractory material, etc.

5.The crush of high abrasive materials resistance and secondary disassembly, desulphuration of thermal power and metallurgy, slag and construction waste.

6.The production of glass,quartz sand and other high purity material.

Working Principle

The entire center feeding: Material falls the feed hopper, then enters the high-speed rotary sling wheel from center feeding hole, which is speeded immediately in the sling wheel. The speed can reach several dozens times of the gravity acceleration. Then it is thrown from the sling wheel. First, it is crushed with other rebounded material fell freely from the sling wheel. Then both of them are impacted to the material lining (rock-rock) or strike back block (rock-iron), rebounded and stroke to the top of eddy cavity in the inclined-up direction. Then it moves along deflection-down, and forms a continuous material curtain with the material from the impellers passage. Just like this, the material is stroke, rubbed, crushed twice or more, then is discharged from the down discharging hole.

VSI sand making machine featuers:
VSI series of Vertical shaft Impact Crusher introduces German technology. VSI Sand Maker is key equipment in sand making area. VSI is a kind of totally new high efficient crusher. It has the following features:

1. Rotor with deep chamber increases 30% capacity after perfect design.

2. Side plate direction can be changed to increase material utility ratio, operating ratio can be increased 48%.

3. Worn hammer with combined type is only changed to reduce operating cost 30%. Another pair of vice hammer is added to prevent from damaging main hammer and side plate.

4. The most key wear resistant material uses wear resistant and high temperature resistant material.

5. Rhombus shape impact plate is used to prevent side plate from being damaged.

6. Bearing is famous international brand imported from Japan, Sweden, America, etc.

7. Perfect discharge and smooth curve reduce resisting force when material flows, so capacity is increased greatly.

8. Spread dish with double purposes can make two feeding ways change easily.

9. Special seal structure under main shaft guarantee no oil leak without seal.

10. Motor with high grade of protection is selected. The motor has features of high efficiency, low noise, etc.
