The heavy-duty jaw crushers come with simple parts that can be easily repaired or replaced.They are composed of a replaceable impact plate which protects the barrel, mainframe protective liner, lock-out pin that increases the safety, and wide bearings that allow longer service life.With all these parts, the maintenance of jaw crushers is very convenient and easy.
The jaw crusher teeth plate wear a chisel wear.Pz250-500 jaw crusher teeth plate, for example,ore vibrating feeder the material of the tooth plate is water toughening the standard high-manganese steel.Observe the grinding of the tooth plate can be seen that the surface of the tooth plate is squeezed into the concave and convex portions of the material, then be abrasive pushed to the formation of the pressure of the tongue grinding surface grinding surface can be seen a lot of abrasive sharp corners short-range sliding caused by the scanning electron microscope wear scar, and can see the surface of the tooth plate micro-cracks.
The raw material is transferred to jaw crusher for primary crushing by vibrating feeder, then the crushed materials are transferred to sand-making machine through belt conveyor for secondary crushing.The materials crushed will be transferred to the vibrating screen.The materials with suitable size will be transferred to sand washing machine, after being washed, then clean final products will be discharged.The others with unsuitable size will be screened from vibrating screen, then they will be transferred to the sand-making machine, thus forming a closed circuit manifold cycles.
Quartz particles are sedimentary rock formed by the combination of silica cements whose structure is mainly composed of cryptocrystalline secondary quartz, and the content of cement is usually about 30% to 75%.The quartz particles crystallization in the cemented are small with a large amounts of impurities thus being easy to change upon heating.So when it comes to improve broken materials quality, 69-mode jaw crusher with stable performance is the best choice.
The manufactured sand production line consists by vibrating feeder, jaw crusher, sand making machine, vibrating screen and belt conveyor as well as other mining gear.In accordance with distinct procedure specifications, several varieties of mining gear might be combined to meet the technological needs of various prospects.

Due to their smaller physical size, jaw crushers are also ideal for tight spaces, such as underground mining and mobile crushing applications, where some other primary crushing solutions do not fit.
Metso grizzly feeders are optimized to work with nordberg c series jaw crushers and nordberg np series hsi crushers to offer seamless performance.However, they can be applied to other crushers as well.
Designed to fill the gap left in the market by cone and jaw crushers, horizontal impact crushers are ideally suited for contaminated materials and can easily handle any clay, dirt or metal mixed in with the feed material, such as rebar, wire mesh or dowel pins.Horizontal-shaft impactor (hsi) units produce a uniform cubical product and can deliver high reduction ratios, allowing them to accept all in-feed and providing maximum productivity in both primary and secondary applications.Whilst hsi units can handle hard material, they are ideally suited for soft-to-medium rock.
The jaw crusher is mainly composed of a frame, a movable jaw assembly, a movable jaw, a fixed jaw, a triangular wheel, a flywheel, a bracket, a side guard, a discharge port adjusting device and a driving device.Because of its simple structure, easy manufacture, reliable operation and convenient maintenance, it has been widely used in crushing operations in metallurgy, chemical industry and mining industries.
A part of the material that meets the requirements is sent to high-efficiency impact crushing and then crushed, that is, sand machine for fine breaking.After shaping and sand making, the material with qualified particle size and limestone material are cleaned and removed by sand washing machine, and the finished product will be the material we need; the other part of the material with unqualified particle size will be returned to the fine jaw crusher for re-crushing, and then screened and recycled repeatedly, so that users can get more satisfactory results.
When a jaw crusher works, the motor starts the belt wheel to drive the centrifugal shaft to rotate.The movable jaw blade suspension shaft gets to and away the fixed shaft periodically, which causes a press, rubbing and grinding, etc.To the raw materials.Crushed stone falls down gradually and are discharged out of the jaw crusher when the particle size meets the requirements.
