Predicting Jaw Crusher Performance

aspect when considering the performance of a jaw crusher. Our industry-leading stroke is amplified from top to bottom, being at its longest in the lower parts of the cavity. This increases the open area between the jaw dies allowing the material to have more space to get out, while also enabling inter-particle crushing. This design principle

1. Introduction. Jaw and cone crushers are commonly used in the mining and aggregates industry. Today, it is possible to predict the performance of a cone crusher, provided the geometry, crusher settings and the characteristics of the material fed into the crusher are known (Evertsson, 2000).The geometry of the crusher will change because of wear.

The product throughput is critical when selecting and determining the performance of a gyratory crusher. Under a fixed mechanical drive system and feed size, the product throughput is predominantly determined by the specific energy (kWh/t) of the rock [5,6], the mantle rotational speed and the closed side setting (CSS).Historically, the crushability test [7,8,9] was …

There are several factors that affect jaw crusher performance. Here are a few things that can help you avoid production losses.

The prediction of crusher performance is typically concerned with the size distribution of the product exiting the crusher, the machine's power draw, and the capacity. The capacity of a jaw crusher is dependent upon the operating characteristics of the machine and …

Recently, Barrios et al. [18] performed such DEM modeling that simulates the performance of a laboratory-scale jaw crusher. They concluded that the performance factors such as throughput, product achievement, compressive forces acting on jaw plates, size reduction ratio (SRR), and specific energy consumption could be estimated, focusing on the CSS.
