A jaw crusher is a compression type of crusher. Feed material is reduced by squeezing it between a moving piece of steel and a stationary piece of steel, with the discharge size controlled by the gap setting, ie the space between those two pieces of steel. The tighter the setting, the smaller the output size and the lower the throughput capacity.

It is well known and taken for granted that the efficiency of energy use by comminution (i.e. breaking, crushing, grinding) equipment is very low, typically less than 10%. Most of the process input power is dissipated as heat and noise and ineffective deformation of the material to be processed and the device itself.
Show abstract. ... Similarly, the crushing of 20 cm feed stock to 6 cm rock would require an energy input of~0.8 kJ/kg. Because the efficiency of comminution equipment is typically less than 10% ...
Likewise, to obtain a specific output, each type of crusher requires different maintenance tasks to keep it running efficiently. Operators who can achieve this, along with a consistent feed to the crusher, will be the most efficient and, more importantly, the most profitable. Jaw crushers. A jaw crusher is a compression type of crusher.

Small jaw crushers are hot in market The jaw crusher is a primary rock crushing equipment. In recent years, the market for small or mini jaw crushers has been hot, and the orders received by our company have continued to increase, which is larger than before. So why is the small jaw crusher so popular?
Granite Jaw Crusher Due to the large feeding inlet and strong crushing capacity, jaw crushers are often used to crush bulky granite (above 450mm) into smaller sizes. It is an efficient and popular primary crusher for granite. In addition, the fine crushing jaw crusher developed by Ftmmachinery can also meet the fine crushing needs of granite.
The crushing ratio of a jaw crusher results from the maximum achievable final fineness in relation to the maximum feed size. For Retsch jaw crushers, this lies between 12.5 and 220. A high value reflects the capacity of a jaw crusher to accept large sample pieces and provide powerful crushing performance, resulting in high final fineness.

Besides being an important item for the machine's performance, the jaw crusher's jaws are responsible for front frame and swing jaw protection. Wear generally causes loss in production due to increased crushing angle, loss of tooth profile, reduction of the CSS to compensate the possible lamellar effect, etc.
Best suited for secondary crushing applications, cone crushers are designed to crush pre-sized materials, usually 100mm, 150mm or 200mm, depending on the size of the crusher. Cone crushers can form finished products down to 12mm or less. Like the jaw crusher, the cone crusher provides a relatively low cost crushing solution, but there are ...
When the crusher works at a lower power demand, the panel lowers the engine rpm from 1,900 to 1,750 for lower fuel consumption, while still maintaining the torque curve. If full horsepower is needed, the panel sends a signal to increase the rpm," explained O'Neill.
Crushing setting: Efficiency Ideally, the reduction ratio of a jaw crusher should be 6:1. There are different ways to calculate reduction ratio, but the best way is something called the P80 factor. The reduction ratio is then calculated by comparing the input feed size passing 80 per cent versus the discharge size that passes 80 per cent.
For a jaw crusher the thickness of the largest particle should not normally exceed 80–85% of the gape. Assuming in this case the largest particle to be crushed is 85% of the gape, then the gape of the crusher should be = 45.7/0.85 = 53.6 cm and for a shape factor of 1.7, the width should be = 45.7 × 1.7 = 78 cm.
