My friend Alex the SAG Mill Expert says this equation you picked up doesn8217t look right.The numerator is calculating the volume of one swing of a jaw times thedensity of material in the chamber times the number of cycles perminute. This should give you the mass of material crushed per minute.
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.
The material is crushed between the two jaws so the wear of the liner is the main problem of the jaw crusher. And the types of wear and tear are mainly divided into the following cases.
In the jaw crusher the ore is crushed and reduced to the required particle size. When the moving plate moves away from the fixed plate the ore is sliding down freely from the upper portion of the crushing chamber to the discharge port under the action of gravity. During this process the ore slides down along the surface of the jaw plate and causes sliding friction which makes the jaw plate be worn. Therefore the abrasive wear is an important wear type caused by the squeezed ore.
When the ore is squeezed and ground under the huge mechanical force of the jaw plate it is easy to form hard sharp edges and corners and continual interaction between ore and the jaw plate makes the surface of the jaw plate appear very deep scratches dense grooves and large-area deep pits. As a result under the strong chiseling action the jaw plate develops plastic deformation metal rheology brittle fracture and spalling causing the material of jaw plate continuously to migrate and lose and gradually become thinner. Therefore chiseling wear is the main form of wear.
Jaw crusher has a large crushing force and fast running speed. Under the action of the huge impact and crushing stress it withstands long-term and periodic contact fatigue load and is prone to fatigue crack. Therefore fatigue spalling is also one of the causes of wear.
In order to protect the environment and improve working conditions a water spray facility is installed on the site of the jaw crusher for dust suppression. At the same time the water directly contacts the raft which accelerates the oxidation and corrosion of the raft and causes corrosion and wear of the raft.
The wear of the jaw plate presents complexity and diversity and is affected by factors such as materials abrasives environmental media and relative motion. The value of the moving motion is usually reduced to solve the wear problems. In recent years with the rapid development of computer technology software simulation is used to comprehensively consider various factors that cause wear and dynamically imitate of the crushing movement of the jaw plate so as to more comprehensively analyze the wear rules of the jaw plate and finally reduce its wear rate.
In addition to the wear problem of the jaw plate there are many other problems caused by parts and components can not be ignored. Next we will introduce the failure analysis and troubleshooting of the jaw crusher.

When testing aggregates ores coal and coke in geotechnical or construction materials testing laboratories sample preparation often involves the reduction of particle sizes from the initial bulk or field sample. Many of these materials are hard tough or brittle so crushing them to smaller sizes is an ideal application for robust rugged and durable jaw crushers.
All jaw crushers operate on the same straightforward principle two hard-faced heavy plates or jaws crush large particles between them. One powered jaw reciprocates in an elliptical motion opposite a stationary jaw mounted in the frame.
During an operating cycle the gap between the two jaws opens a particle drops in the jaws close in and crush the particle. Further crushing of the fractured pieces continues until particles are small enough to fall through the bottom opening by gravity. The jaws face each other at a slight vertical angle so particles become smaller as they progress toward the bottom.
A simple adjustment of the distance between the two jaws regulates the final sample size. The term final size can be a little vague. It refers to the approximate maximum particle size at completion of crushing but the size range and distribution can vary considerably based on the material properties of the sample.
Many factors make laboratory jaw crushers the optimum selection for effective and efficient primary crushing of hard brittle rock-like materials.
Jaw crushers can also have some disadvantages compared to other types of size reduction.
The selection of the best jaw crusher for your application will naturally be governed by the particle size volume and properties of your bulk material along with the desired particle size and quantity of the final sample. The size of the jaw plates limits the particle size capacity and determines the size of the feed opening. In general maximum particle sizes are about 70-80 of the feed opening but this can vary by manufacturers and models. Jaw materials are available in a variety of materials to adapt to the hardness and toughness properties of samples and to extend service life.
Medium Crushers These useful models have the capacity size and power to meet most primary crushing functions in the lab. Options for voltage configurations add to their versatility.
Large Crushers When size capacity and throughput are the most sought-after features these units are the best choice. Options for power by gasoline or Diesel engines mean the crushers can work on-site at remote laboratories or pilot plants.
