High-tech level of Modern Sand Making Machine 

SC Vertical Shaft Impact Sand Making Machine
SHANGHAI DONXE MACHINER CO., LTD is a leading stone crushing machine and screening equipments manufacturer in China, provides stone crushing machine and screening equipments for various industries such as mining, building material, metallurgy, environmental protection, transportation, chemistry, energy and so on. 
1. High-tech level of Modern Sand Making Machine
Along with the increase in domestic demand, the country puts more efforts and investments in infrastructure projects of highway and railway, which results in urgent need of large amount of sand stone. But natural sand resources can’t meet the demand of sustainable development any more. Under this background, we cooperated with KOBE Steel Group, industrial magnet of Japanese crusher, and China National Heavy Machinery Corporation, adopting world-class technology and equipment to develop and manufacture this vertical shaft sand making machine with high-tech level. 
2. Structure of Vertical Shaft Impact Sand Making Machine
SC series sand making machine is composed of machine body, feeding pipe, impact board, vertical shaft with rotor, motor, feeding hopper, crushing chamber, pedestal, etc.
3. Performance Advantages of Vertical Shaft Impact Sand Making Machine
Impact plate installed in machine body is made by special high-chromium cast steel, with high abrasion proof and for not being fastened with bolts it is convenient to be replaced. It uses closed rotor and feed through rotor.
Air cycle device is installed on both sides of materials feeding opening, which make the wind produced by rotation of rotor cycles in this device, thus to reduce the dust which is discharged outside. 
Rotor is equipped with abrasion proof gaskets which prolong its useful life and reduce amount of easily damaged parts, to decrease operational cost. Because of being adjusted balance, the rotor with high speed realizes low noise and vibration.
Impact board can be reversed to use and its installing position can be adjusted up or down to make best use of its function. Its lubrication is adopted with grease.
4. Crushing Principle of Vertical Shaft Impact Sand Making Machine
Ready-to-crush materials are put from the top feeding opening, into high speed central part of rotor. The falling materials are threw out at high speed under the strong centrifugal force of rotor and crushed when they strike the impact board of main machine. When install impact board, the collision between materials and impact board should be a right angle to exert its excellent crushing performance. Artificial sand after crushing is discharged from the lower part of machine.
5. Advantages of Vertical Shaft Impact Sand Making Machine
Firstly, it has excellent crushing performance; 
Secondly, it decreases operational cost greatly: 1.less easily damaged parts 2.easily damaged parts are made by special high-chromium cast steel or extra hard alloy, so their useful time are prolonged extensively than the parts made by other materials.3. Impact board can be reversed to use and its installing position also can be adjusted, so it has high rate of final products.4.more convenient replacement of easily damaged parts. 
Thirdly, it’s new environmental machinery products, can reduce damage of public nuisance.1.low noise and vibration, reduce noise pollution 2.less dust discharged outside reduce environmental pollution.
It is widely used in crushing basalt, cobblestone, andesite, granite, etc, and it produces artificial sand by dry processing way. SX vertical shaft sand making machine is to make use of the impetus produced by high speed centrifugal force to let materials strike with each other or materials strike impact board and crush materials finally, so it almost can crush all kinds of materials, especially hard materials, is suitable in mining and building industry.
