Purpose and Applied field

Our Jaw Crushers are ideally suitable for primary and secondary crushing, with well-capacity and high-efficiency, they are widely used for crushing various medium hard rocks and other ore materials whose maximum pressure-withstanding is 2000 kilogram force/cm³ and they are mainly supplied to the departments like Geological coal char、Mine、Metallurgy、Chemical Engineering、Construction Materials etc. And the labs of junior college academies science and research units.

Primary Specifications and Technical data

Main working principled

The Jaw crusher structure includes Fabricated Body、Swing Jaw、Eccentric Shaft、Jaw Plates、Toggle mechanism etc parts. The electromotor drives eccentric shaft through triangle strap, to make the swing jaw moves in adjusted locus, thereby the materials in the crushing cavity are crushed.

The fabricated body is electricity welded by steel plates, the fixed jaw plates tightened by bolts are fixed in the front of steel housing, which assist in impacting the plates. The side plates are fixed in the steel housing side-wall which in the right-and-left of the crushing cavity, for preventing the wearing and tearing of the steel housing side-wall.

The swing jaw is a cast steel moulding, its face fixes swing jaw plates, top hang on the housing by eccentric shafts and roller bearings, its infrastructure is supported by toggle mechanism and it is scroll touching with the toggle mechanism. Fly wheels and Strap wheels with grooves are fixed in the two sides of the eccentric steel shafts. The steel housing is welded into the machine seat, electric motor sliding-track is fixed in the machine seat with bolts and a outlet drawer is fisted in the outlet, but it can expel products downwards directly without outlet drawer.

Toggle mechanism is connected with supporting bolts byφ9mm pins when the materials in the crushing cavity can not be crushed and the loads are increased suddenly, viz. The pin parts itself rapidly to protect other works from being destroyed. In the end of supporting bolt, there’s a hand wheel, it is used to adjust the outlet width size. The adjusting process is that remove the setscrew first, then circumgyrate the hand wheel, after adjusting, tighten the setscrew again, the connection between pothook and spring at the down most of the swing jaw make the toggle mechanism and swing jaw not to work outside, and they are adjusted by nuts.

Installation instruction

The machine is supplied to users after being assembled whole by our manufacture factory, please examine it when you get ,in order to eliminate the possible faults during transporting.
1.Due to biggish working vibrancy, so we suggest to mount the jaw crushers on the concrete foundations, for reducing vibrations and noises, you’d better underlay hardwood temples, rubber strips or other cushioning- vibrancy materials between the crushers and the concrete foundations.
2.The foundation weight is approximately 5-10 times of the machine weight, the foundation depth is deeper than the ground freezing depth of this place .With regard to the machine installation and terra feet bolts location.
3.Before adjusting the outlet width size, you should loosen the tense spring first. And after adjusting, appropriately adjust the spring tense degree, for preventing the toggle mechanism from working outside.
