In the current era of the demand of river sand is insufficient; the use of the
vertical shaft impact crusher plays a very important role. A new type of the vertical shaft impact crusher has simple and reasonable structure, and it is from the hammer crusher, the use of ultra-low cost, unique bearing installation and advanced spindle design make the machine with a heavy load and high-speed characteristics.
The
vertical shaft impact crusher has finely, coarse grinding function; Equipment of high reliability and high security device, ensure that the equipment and personal safety；Many advantages made the vertical shaft impact crusher equipment popular. Sand is an important part of the configuration of concrete indispensable, the total accounted for 3/1, with the rapid development of building industry, the requirements of the amount of sand is increasing in construction. Because the river sand as a kind of local resources, in a short period of time could not regenerate, so in some areas appear natural sand resources in our country gradually reduce, even without natural sand. Especially the contradiction between supply and demand of sand concrete, and the price of sand is higher and higher, affects the progress of the construction of the project.
The
vertical shaft impact crusher is the most common cement engineering use of sand mechanism equipment. In the process of production, the quality of the finished product and sand fineness modulus whether meet the requirements of the end, most of them are according to human experience or by drying, screening, weighing and sampling methods such as discriminant. This method has two fatal flaws:
1.By artificial experience to judge the quality of sand, vary from person to person, so the error is large, not reliable.
2.Sample weighing though the determination is accurate, and the time determination is long; Cannot feedback control at any time, and increase the artificial workload.
With the increasing demand of machine-made sand mechanism sand standard, also put forward higher requirements, Shibang Machinery Co. Ltd. after study, mainly consider the automatic control mechanism of sand quality, strengthen the research work of the
vertical shaft impact crusher machine control system. In respect of sand and gravel aggregate, the current research to replace river sand material more is the artificial sand, also known as the mechanism of sand, the mechanism of sand is composed of mechanical crushing, screening. Through the rational use of the mechanism of stone powder, adjust the concrete sand ratio, can be configured and easy good concrete.
Shibang machine after years of research, introduced the international advanced technology, what introduce f a new generation of VSI new type the vertical shaft impact crusher. More than one field understand customers from designers and equipment operators. By improving the yield, reducing cost, prolonging the repair cycle wear, and reducing the amount of repair, becomes a stone integer, artificial sand making industry, refractories, ball mill and ore processing in areas such as the preferred equipment.
