Jaw crushers are the most common solution in underground applications when the throughput is below 1000 tonnes per hour, depending somewhat on the scalping solutions. Above 1000 tph, primary gyratory crushers are an option. After the throughput reaches 2000 tph, jaw crushers are very rare, with the exception of a parallel plant layout.
The main function of the toggle plate is to transmit the crushing force and absorb the reaction force generated during the crushing process. When the movable jaw moves down, the toggle plate compresses, and when the movable jaw moves up, the toggle plate expands. This movement creates a rocking motion, which helps to break up the …
1.2 The jaw crusher. Crushing is the first stage of size reduction of mined rocks. Primary crushers are heavy-duty machines, used to reduce the run-of-mine (ROM) ore down to a size suitable for easy handling. A line diagram of a double toggle jaw crusher and its main components is shown in figure 2. The jaws are set at an angle to each other.
A jaw crusher is a machine that breaks down large rocks into smaller pieces of rock, gravel, or dust. It does this by placing two jaw plates perpendicular to each other and squeezing the rock between them until it is broken into small pieces. A stationary jaw plate and a movable jaw plate control the movement of these jaw plates.

Regular maintenance is key to ensuring optimal performance and noise reduction in jaw crushers. Worn-out parts, such as bearings and belts, can lead to excessive noise. Hence, regular inspections and timely replacements help maintain a quieter and more efficient operation. This practice can also improve the lifespan of the crusher, resulting in ...
Jaw Crusher is a basic sample preparation unit and is essential to address all primary size reduction requirements. Desired crushing takes place when fed particles experience stress and the compressive pressure exerted by the jaw blade toggling action exceeds its fracture stress. By this action the feed particles are crushed to smaller sizes.
Powerful and robust. Jaw Crushers are ideal for pre-crushing of very hard, hard, medium-hard, brittle, tough and temperature-sensitive materials. The sample is crushed under high pressure between one fixed and one movable crushing jaw. The grinding parts are available in various steel types, hardmetal tungsten carbide and zirconium oxide to ...
This jaw motion also reduces the common scrubbing action found in single-toggle jaw crushers. These crushers are renowned for their outstanding strength, reliability for continuous operation, and cost-effective maintenance. The design allows for an extended jaw length, resulting in more crushing strokes and a higher reduction ratio, and is ...

pulverizer. Figure 3 illustrates the angle of nip in a jaw crusher. Figure 3: Angle of nip in a jaw crusher 2.3 Crusher Jaw Plates Compression of materials undergoing crushing in a jaw crusher is achieved when the movable jaw presses the feed against a stationary jaw. These jaws can be flat surfaced or corrugated.
Advantages of a Jaw Crusher. 1. Jaw crushers are comparatively inexpensive. 2. Both the structure and working of a jaw crusher are quite simple. 3. The product size is quite small and can range up to millimetres. 4. Repair and maintenance of a jaw crusher are convenient and easy. 5. The reliability of a jaw crusher is significantly high. 6.
Blake jaw crushers, also as double toggle jaw crushers, are characterized by the position of the pivot of the swing jaw, which is located at the top of the machine. This design allows for a larger feed size and a higher capacity, making it suitable for primary crushing. The motion of the swing jaw in a Blake crusher is predominantly vertical ...
Double-toggle jaw crushers. In a double-toggle jaw crusher, the moving crusher jaw is driven by the eccentric shaft that moves the front and rear toggles up and down. Each shaft revolution causes the moving crusher jaw to close at the downstroke and open up during the upstroke. The toggle is kept in place by spring-loaded tension rod.
