Business Value of Sand
In the construction industry, almost every project can not leave sand. Making concrete, limestone sand, granite sand and some other sand are the key material. In building, sand is playing an important part in building the wall. In road construction, sands form the road surface. In bridge construction, sand is also necessary. As a result, sand making industry attributes more and more investors. While, natural sand is quite limited and many countries begin to forbid exploiting the natural sand, sand producers have to purchase sand making machine for making artificial sand. Gulin VSI crushers (VSI sand making machine), certified by the CE, ISO9001, are very popular in many countries like south-America, Africa countries, Russia, Austria, India, Thailand, Vietnam, Malaysia, etc.
Gulin VSI Crusher
Gulin VSI crusher (VSI sand making machine-vertical shaft impact crusher) adopts the advanced technique and optimized design, it has superior property. Take the quartz for example:
After the primary and secondary crushing process, the quartz aggregates meet the max. Feeding-size of the VSI crusher (Gulin VSI crusher for sale max. input-size is about 50mm). The quartz aggregates are carried to the VSI crusher for quartz and store in the feeding hopper. Producer can adopt two kinds feeding methods, one is central feeding and another is cascade feeding.
If the VSI crusher adopts cascade feeding, the quartz is divided into parts by the distributing plate in the center when they come down from the hopper. One part will enter the impeller of high rotating-speed and will be accelerated in impeller and then flow out at an extremely speed (it is about 60-70m/s). They will impact materials that fall from distributing plate edge and all of them will go to the vortex cavity and form lining material and rebound back for crushing again until they fall downward and discharged from the VSI crusher. In this way, it saves the VSI Crusher Cost for production greatly.
If central feeding is adopted, the quartz material will go through the hopper and enter the impeller directly. Then they are accelerated and thrown out at a high speed and impact on the guard liner plates. Gulin B series deep rotor sand making machines adopt optimized guard liner plates design and it ensure low operational cost by adjust the install method. Also, central feeding avoids too many powders, so it is widely used in sand making plants.
Which VSI crusher is suitable depends on the final design. If you want to know more details or if you have some doubts, just be free to contact us.
