Jaw Crusher. Jaw crusher is often used as primary and secondary crusher for mining, metallurgy, construction and some other industries. It takes large pieces of rock, ore, concrete, or other materials, and crush them down to smaller sizes for further processing in a ball mill or hammer crusher. Feb 01, 2014"Successful jaw crusher maintenance requires the right resources, the right tools and the right approach," says Bill Macini, a service technician.. Certainly when an operation is down, whether for preventive maintenance or component failure, there is always the pressure to get the plant up and running as soon as possible.
Apr 26, 2017Jaw crushers are used for coarse grinding brittle, medium-hard to hard materials up to a Mohs' hardness of approx. 8.5. Here reduction ratios of up to 1:100 are possible depending on the actual model concerned. The crushing jaws are executed by us in two versions: In a laboratory model with integrated control system, feeding funnel and
A Jaw Crusher reduces large size rocks or ore by placing the rock into compression. A fixed jaw, mounted in a V alignment is the stationary breaking surface, while the movable jaw exerts force on the rock by forcing it against the stationary plate. The space at the bottom of the V aligned jaw plates is the crusher product size gap, or the
May 13, 2019Additionally, jaw crusher feed should be pre-screened using a grizzly screen prior to crushing to remove material finer than the closed-side setting. Setting jaw crushers. Ideally, the reduction ratio of a jaw crusher should be 6-to-1. There are different ways to calculate reduction ratio, but the best way is something called the P80 factor.

Jaw Crusher Information – Asphalt Plants, Jaw Crushers and Protecting the Jaw Crusher: the Toggle Plate. The bottom of the pitman is supported by a reflex-curved piece of metal called the
Jaw Liners that are worn too thin can crack and damage the crusher body resulting in expensive repairs and prolonged downtime. Worn Jaw liners affect production and draw more power. Figure 1 above: Shows the Liner profile, H is the tooth height of a new liner and 20% of H is an indication of when to rotate the Jaw liner.
Rock enters the jaw crusher from the top of the machine and gets compressed between two surfaces — the fixed and moveable jaw. The rock will continue to be crushed until it is small enough to fall through the opening. Ensuring that the size of raw material is appropriately matched to the jaw opening, can alleviate blockage incidents.
Jaw crushers are widely used in mining smelting, building materials, roads, railways, water conservancy, and chemical industries. There will be a strong vibration in the work, because of the large hardness of crusher materials. Therefore, the work of the installation of a jaw crusher
Jaw Crusher Components: There are several main parts of jaw crusher: frame, jaw plate and side guard plate, and transmission part. The frame is a four-walled rigid frame, and it is used to hold the eccentric shaft and stand the reactive force of crushed material. So, the frame needs sufficient strength and rigidity. It is usually made of cast
