Crusher industry steps into a gloomy period Numerous uncertain elements in the market economy lead crusher industry to step into a gloomy period and naturally slow down its developing pace. Meanwhile, that has evoked the realization of the crushing manufacturers to innovate and reform to seek a way out. Many experts point out that the crushing equipments with high performance and innovativeness is bound to become the mainstream in the market. They should achieve the innovation in the aspect of technology and products, make differentiated and unique products and promote core competitiveness. Only in that way can they finally gain the most market share.
The main shaft is an extreme vital part of the gyratory crusher, it must have sufficient strength and rigidity to ensure a normal operation of the crusher. The foregoing fracture accidents of the shaft told us that they mostly occur in the upper Gewindefreistiche, the lower part matching with the cone and the interface of two different diameters. The factor that caused the fracture is due to the crushing of oversized pray at the discharge opening and too fast discharging. The products granular property accounts a lot in Crusher s operation, model selection or the next manufacturing and processing as well as flow design and calculation. Elements influencing the granular property: property materials, weekends content during feeding, the type of a crusher and operation etc. Similar to granular property of the gyratory crusher products, it can be selected according to the grain size characteristic curves in the instructions of the gyratory crusher. The combination crusher selects the appropriate ways of applying force according to the particle size, nature of materials and the requirements of productions in order to get the best crushing effects with the most appropriate and the least time and energy consumption.
The combination crusher mainly shows the its characteristics during the crushing operations from the following aspects. The crusher will use the crushing and impactive way of applying force in face of the pipes with larger particle size or the medium hard material. At this time, there will be teeth on the surface of the crushing equipment tool which is favourable for operations. The crusher will use the crushing, impactive and milling force in face of the material with hard material with smaller particle size. There will be no teeth on the surface of the tool at this time. The combination crusher will use milling, crushing force in face of the powdery or pulpy material and impactive. There will be sharp teeth on the surface of the crusher tool. The crusher mainly use the crushing force for the abrasive material. At this point, the surface of the tool is smooth. The material is made up of a variety of components, which can make a variety of force used in combination.
