The most important application fields in the sand making equipment in our country are cement, road construction and mining industry, among which about thirty percent are applied in them. In the past few decades, China’s economy has been developing in a stable way and the GDP growth has exceeded eight percent. The development of road building cement and some infrastructure will certainly push the increase of sand making manufacturers, so this industry will have far brighter development prospective in the future ten or twenty years. Development of the west regions has triggered great demand for sand makers, however, with the further development of our economy, Middle China promotion will also be put into effect, which will inevitably drives the improvement of this industry, because it is an indispensable raw material in the building, the production capacity will always turn people off with this machine.
PCL sand maker is a new type crushing equipment that is researched and developed on the basis of many years’ machinery manufacturing experience and combined with the principle of vertical shaftimpact crusher. It is widely used for fine crushing of various rocks. So far it has replaced such traditional machines as hammer crusher, roller crushing equipment and become the mainstream equipment in the sand making industry.
Artifical Sand generating flow
There is scarcity of natural sand resulting from heavy demand in expanding construction activities which forces to locate the appropriate substitute for sand. The least expensive and also the simplest way of getting substitute for all-natural sand is by crushing natural stone to get artificial sand of desired size and grade which could be totally free from all impurities.
The advantage of using superior river sand is the fact that it mixes quickly with cement and bonds well, generating the plastering operate much less cumbersome for the masons and giving a great finish to the buildings. But however, the continuous mining of sand causes environmental troubles.
In such a scenario, artificial sand is seen as a welcome alternative to natural sand. Hongxing has hit upon the thought of designing a sort of sand making machine so as to making sands from several types of stones . The artificial sand would be obtainable in two grades – 1-3 mm for plastering and 3-5 mm for all construction function. As it would be double-washed and silt-free, it would bond better with cement and would need lesser curing time than river sand.
The raw material is transferred to jaw crusher for main crushing by vibrating feeder , then the crushed materials whose size is larger than 40 mm are transferred to vsi crusher by means of belt conveyor for secondary crushing. The materials crushed might be transferred to the vibrating screen. The materials with suitable size will probably be transferred to vsi crusher, just after getting washed by sand washers, then clean final products might be discharged. The other people with unsuitable size might be screened from vibrating screen, then will probably be transferred for the vsi crusher, this forms a closed circuit manifold cycles. Sizes of final items will be according to our customers’ requirements. If it’s the dry method, the classifier and deduster will be attached in accordance with you requirement.
