Jaw crusher is suitable for crushing hard material (compression strength less than 250Mpa). Por ejemplo: coarse and fine crushing operation by hammer crusher of iron ore, slag, phosphorus ore, copper ore, ore silicone, limestone, quartz, stone, ceramic and solid materials with similar hardness; breaking bulk materials of concentrator, stones factory, cement plant. Features: low use and maintenance costs, high ratio of reduction, high reliability, small power consumption. Be widely used in mining, building stones factory, building materials, metallurgy, ceramics and other industries The stone manufacturing line is not difficult to understand, it is nothing but a organic integrated whole that composed by people of the crusher, screening, transmission machinery and then it becomes a well known production line. According to the different requirements of production process, we should use the jaw crusher with different type and model in stone producing line.Some stone producing line adopts a broken molding, but some mineral processing equipment uses secondary crushing to shape. Its main process is: the material is through the feeding machine, jaw crusher, after they are broken, they will enter into the sand producing machine, and then they begin to be screen to classify.
In the jaw crusher, shown in figure below, the moving jaw is pivoted at the bottom. The minimum movement is thus at the bottom and to 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.As the professional manufacturer of complete sets of mining machinery, such as cement production line, Henan Hongxing is always doing the best in products and service. Zhengzhou Hongxing Machinery has been committed to researching and manufacturing mining machine for many years. By virtue of sound service and quality product, Hongxing Machinery wins the trust of customers. Meanwhile, jaw crusher produced by Hongxing Machinery is the most popular one with large crushing ratio, even product coexistence, low operation cost, simple structure and convenient maintenance.
In particular, Hongxing Machinery has always been at the domestic leading level in large jaw crusher design and production. Jaw crusher is mainly used in the first crushing procedure in crushing production line. It can be used separately or together with other supporting equipment. Thus, users should fully understand the working principle of jaw crusher and the common fault in production process. In our routine work, the most frequently used crusher in ore dressing plant or stone is jaw crusher plant. Compared with other crushers, jaw crusher has the advantages of low cost and high efficiency. Due to the fact that wear-resisting remove requirement of jaw crusher is high, so the material is usually wear-resisting high manganese steel lining plate. There are two jaw plates in crushing chamber; one is fixed on the upside of crusher; the other is mobile and forms to crushing chamber with the fixed jaw plate.
