Cone Crusher Manufactures increased investment in science,of the equipment manufacturing industry a good atmosphere, and further build the equipment manufacturing industry support independent innovation policy system.In the perfect policy system support, while increased investment in science and technology. The cone crusher appear load 'galloping', has mainly the following reasons:
1) cone crusher drogue less contact with the spindle, in the crusher break materials gap occurred 'galloping', which is actually still belongs the air copper drogue commission heat inward protruding turn 'galloping'. If the feeding still can not pressure, the spindle rotation galloping out of control. The pressure resistance strength is under 350Mpa, that is, suitable for primary crush. Hydraulic Cone Crusher can be used in mining, metallurgical industry Gyratory cone crusher and mushroom cone crusher belong to cone crusher and gyratory cone crusher is a type of coarse crusher.
2) the cone crusher drogue crack during running, with spindle contact surface becomes smaller, the oil film was destroyed, so dry friction temperature excursions to 'galloping'. This mining machine has the advantages comparing with the other same products
3) the cone crusher drogue is in operation effected by the role of non-broken (over iron), resulting load is too large, irrigation zinc loss, causing bushes up, spindle and bushes gap become smaller to'galloping'.
4) The cone crusher spindle and drogue installation gap is too small, or the gap becomes smaller, resulting in additional load generated between the drogue and the spindle, due to bowl-bearing long-term use to wear thinner, pyramidal sink, significant increase the contact stress, caused by destruction of the oil film to 'galloping.'
5) spindle cylindrical surface of the cone crusher wear seriously, and even appear shades trench, so the shaft and bushes contact situation deterioration caused the 'galloping'.
6) between the transmission parts during the crusher operation will generate a lot of heat, through the heat exchanger under normal conditions to heat release out to achieve the thermal balance of the system. If excessive heat generated by the system, exceed the cooling capacity of the cooler or chiller problems, reduced heat transfer efficiency, the thermal equilibrium will be broken. The oil temperature continues to rise, decline in oil film strength and produce dry friction, even in the bowl-shaped bearing, vertical sleeve, sleeve and the sleeve sliding contact area occur burns.
