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 ores 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: materials’ property, fines content during feeding, the type of a crusher and operation etc.
Similar 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. Therefore, for a better operation of the crusher, Henan Hongxing Mining Machinery will describe the preparations for you before starting.
1.Examining carefully that whether each part is in good condition, all the connectors are tight and obstacles exist in the conveying part（ belt conveyor ）.
2.Checking that whether there’s stone or iron ore(ore beneficiation) in the crushing chamber. The foreign substance like ores must be cleared away to make sure that the crusher get started in a non-load condition.
3.Checking the auxiliary equipments such as the feeder, belt conveyer, electric equipment and the signal device that whether they are in good condition.
4.Examining that whether the size of the discharge opening complies with the production process requirement.
5.Examining the oil level and oil temperature in the tank, using heating equipment to heat the oil up to 20 degree when the temperature is pretty low due to cold winter.
6.Checking the lubrication equipment and the interlocks’ condition of the oil pump motor and the crusher motor.
After finished the foregoing inspection and making sure that everything is well-conditioned, then the crusher can be started via the starting procedure.
