Diversity of crusher materials

• Jaw crusher is widely used for medium size crushing of various ores and large materials.
• Mining industry: for crushing various ores, such as iron ore, copper ore, gold ore, etc.
• Building materials industry: for crushing limestone, gypsum, shale and other building materials
• Highway and railroad construction: used for crushing roadbed stone, ballast, etc.
• Water conservancy industry: for crushing stones in water conservancy projects
• Chemical industry: used for crushing chemical raw materials, such as phosphate rock, sulfurous iron ore, etc.

How does a jaw crusher work

The working principle of the jaw rock crusher is based on the periodic reciprocating motion of the movable jaw plate against the fixed jaw plate. The core components are the two jaw plates, the movable jaw and the fixed jaw. The movable jaw plate is suspended on the mandrel and can swing from side to side.

When the eccentric shaft rotates, the movable jaw plate does reciprocating motion, sometimes close to the fixed jaw plate, sometimes away from the fixed jaw plate. When the movable jaw plate is close to the fixed jaw plate, the material is crushed by extrusion, splitting and bending between the two jaw plates;

When the movable jaw plate leaves the fixed jaw plate, the crushed material will be discharged from the bottom of the crushing cavity under the effect of gravity. Through this periodic extrusion and release, the material is gradually crushed into the required particle size.

Mobile jaw crusher Structure Composition

• Industrial jaw crusher mainly consists of frame, movable jaw, eccentric shaft, jaw plate, elbow plate, adjusting seat, movable jaw pull rod and other components
• Rack: the support structure of the whole equipment, usually made of high-quality cast steel or welded, with sufficient strength and rigidity.
• Movable Jaw: It is the main part of crushing materials, driven by the eccentric shaft to do reciprocating motion.
• Eccentric shaft: It is the driving part of the movable jaw, connected to the electric motor through pulley or coupling, and converts the rotary motion of the electric motor into reciprocating motion of the movable jaw.

• Jaw plate: it is divided into movable jaw plate and fixed jaw plate, which is the part that directly contacts with the material and crushes it, and is usually made of high manganese steel and other wear-resistant materials.
• Elbow plate: It is the part connecting the movable jaw and the frame, playing the role of transmitting force and protecting the equipment. When an unbreakable object enters the crushing chamber, the elbow plate will break first, thus protecting other parts from damage.

Why Mining Machinery Recommends Jaw Crusher

• Simple and durable structure: The jaw crusher adopts high-strength cast steel body and high-quality manganese steel jaw plate, which has a solid structure, can withstand huge impact force and has a long service life. Its modular design makes the maintenance easier and faster, only need to replace the parts to restore the normal operation of the equipment.
• High efficiency and energy saving, lower operating costs: unique crushing cavity design makes the material bite more closely, significantly improves crushing efficiency, and reduces energy consumption by 15%~20%. The optimized lubrication system simplifies the maintenance process and reduces downtime, further reducing operating costs.
• Strong adaptability and wide application: the feed size of jaw crusher can be up to 1200mm, and the discharge size is adjustable (10~350mm), which can meet the needs of coarse crushing, medium crushing and other needs. Whether it is hard rock, gravel or metal ore, jaw crusher can easily cope with it, widely used in mining, gravel plant, concrete mixing plant and other industries.
• Large crushing ratio and uniform product size: Jaw crusher has strong crushing ability, can crush large materials into smaller size at one time, and the product size is more uniform, which can meet the needs of different users.

The product model is a reference value, specific according to customer demand, customized to the most favorable price, to ensure quality equipment.
