crushers (C200 series) are 1600 x 2514 mm with motors rated at 400 kW. The largest particle that can enter the opening of the jaw crusher can be estimated by: Largest particle size= 0.9 x gape. The largest particle to report to the jaw crusher is typically defined by the drilling pattern in the mine. Typical Jaw Crusher Characteristics

Furthermore, Angle of Repose (AoR) test was conducted to identify influence of shape characteristics on particle packing behaviour. The study showed that both the techniques (i.e., AIMS and FAA) could differentiate among the quality of fine aggregates produced from different crushers.
Cone crushers. Cone crushers are one of the main choices for secondary crushing. A cone crusher is a powerful machine that is used in large-scale industries for crushing various types of materials into smaller sizes. It works by applying pressure onto the material and squeezing it against a rotating mantle to create compression and force.
Angularity is defined as the sharpness of corners of a 2-dimensional image of the aggregate particles. Angularity is measured using gradient method. The change of gradient is measured over particle boundary using binary particle image (silhouette) of aggregate particles (Equation (1)). The angularity value ranged from 1 to 10,000.
DEM with a particle breakage model has been used to successfully model crushers.. Impact crushers such as hammer mills, VSI and HIS have been simulated. • Energy absorbed determines breakage with geometric rules for progeny generation.. Predictions include power draw, liner stresses and wear, product size and throughput.
Each type of crusher is tailored to handle the specific characteristics of the targeted plastic material, ensuring efficient processing and reducing the risk of damage to the machine. Main Components and Structure. Plastic crushers typically consist of several main components and a specific structure to facilitate the crushing process.
In the piston and die test, the breakage energy is measured and the data is then used for calibrating the energy model.
