The Development Course of Modern Patent Mill

In the late 1990s, the domestic mining enterprise had started to R&D and manufacturing the sand maker. HX series sand maker intermediate crush or fine crush material of various hardness with the function of repeatedly clashing, rubbing and grinding generated by the material in crushing space. PCL series sand maker is widely used in the mining, metallurgy, building material, highway, railway, water conservancy and chemical industry and so on.Last year our company launched vertical shaft sand maker, which puts an end to the backward processing technology relying on hammer crusher and roller crusher and significantly improves the production efficiency of the sand making and stone production line. This machine effectively relieves the influences resulting by the shortage of the sand and stone aggregates on many industries, so that it get wide appraise among the customers.

This series have many advantages, such as big reduction ratio, even granularity, simple structure, reliable working condition, convenient repair and economic operation, which are widely used for mine, smelting, building material, road, railway, irrigation works, chemical and materials with compression strength no more than 320 Mpa.The crusher machine is available as single toggle Jaw Crusher and double toggle jaw crusher. These variants are fabricated from heavy duty plate frames with reinforcing ribs on the surface. All the crusher parts are manufactured from special alloy that can withstand heavy draw. Manganese steel is the preferred material for both fixed and moving jaws. Heavy fly wheels facilitate smooth crushing of the mineral feed. Some double toggle jaw crushers may also feature hydraulic toggle adjusting mechanisms.

In the Double jaw toggle crusher, shown in Figure below, the moving jaw is pivoted at the bottom. The minimum movement is thus at the bottom and a more uniform product is obtained, although the crusher is less widely used because of its tendency to choke. The large opening at the top enables it to take very large feed and to effect a large size reduction. This crusher is usually made in smaller sizes than the Stag crusher, because of the high fluctuating stresses that are produced in the members of the machine.The satisfaction of the customers is the driving force of Hongxing people, so after a short time of enjoyment, Hongxing Machinery continues to devote to the research and development of newer types of products. That keeping up with the time, combining with the needs of the customers and developing the newest sand maker that most suits the customers is the top priority of Hongxing Machinery.
