Jaw crusher frame is divided into two main kinds of a kind of welding machine frame, a kind of cast steel frame. These two frame each have an advantage, while welding frame has certain advantage in price, but in the process of production, the welding frame also can appear some fatal fault, it is broken machine welding frame in the process of production of hubei appear crack, frame as hubei machine the entire device to be the first line of defence, its quality directly decides the service life of the equipment. So what is the cause of Jaw crusher frame welding crack?
Welding frame in general cracking is the main reason for the welding process, of course this is not the only factor. Because of Jaw crusher frame welding process causes craze tend to be some technical level substandard small manufacturer, is the black workshop. These manufacturers in the production of Jaw crusher can not reach, because the factory conditions often work outdoors, if temperature is below freezing in winter, low temperature, when welding the weld metal cooled fast hardening tendency is bigger than low carbon steel, therefore, appear so crack tendency is increased. Second because these small manufacturer of hardware facilities to keep up with, before welding, welding rod without strict drying processing, frame without hydrogen elimination measures after forming, these factors have led to the welded machine frame is unqualified, is also the root of the pitfalls. This is welding process result in the crack of the rack on a couple of reasons, in addition to the production process and some accessories, such as Jaw crusher bracket, bracket if the purchase is unqualified, the machine had not broken material, not timely break, then the powerful impact on machine by machine itself, strong shaking force will result in the crack of the rack, and hubei board has no fixed well, in the process of production activities within the machine cavity, jumped up and down for a long time, this also is the cause of mecha cracking.
Above all, should choose when buying jaw crusher normal manufacturer, do not covet is cheap to choose those small factories, such damage to the machine problems still is their own interests, in the choose and buy of Jaw crusher must first examine the comprehensive strength of the manufacturer, so you can buy the right quality of Jaw crusher.
