HST series single cylinder hydraulic cone crusher is a new type high-efficiency crusher independently researched, developed and designed by SBM through summarizing over twenty years of experience and absorbing the advanced technologies from America and Germany. This cone crusher integrates mechanical, hydraulic, electrical, automatic and intelligent control technologies, and represents the most advanced crusher technology in the world.
HST cone crusher is a high-end mining machine, for which we adopt a large number of automation designs, such as automated over-iron protection; the user does not need to shut down the machine, and the machine will automatically adjust the discharge opening to release foreign matters during operation; when the feeding amount is too large and the machine is overloaded, the motor will automatically stop under action of the thermal protection device to avoid the body damage caused by overload and so on. These automation applications guarantee the production and operation safety, and greatly reduce the accidents.
The full automatic control system equipped on the HST cone crusher will provide manual control, constant discharge opening control, constant power control and many other operating modes for users to select. The internal load of the crusher can be monitored continuously so that the use ratio of the crusher can be increased and the crusher can play its best performance at all times.
The sliding bearing of HST cone crusher adopts special oil wedge design, which can convert the rotating power of shaft into the oil film pressure, and lift the shaft and make it rotate under dynamic lubrication state; a stable lubricating oil film will form on the contact surface between the shaft and bearing, which avoids the direct frictional contact between the shaft and bearing, thus reducing the heat amount and extending the service life of the bearing.
Positive pressure dust prevention system equipped on HST cone crusher can guarantee that the internal pressure in the crushing cavity is always higher than the external pressure, which effectively reduces the volume of dust or other small particles entering the crusher, extending the service life of lubricating oil, and reducing the damage of small particles to the bearing. This design effectively increases the service life of crusher and reduces the maintenance workload.
