The model has been executed under different settings, therein mapping the performance of the crusher in terms of power draw and capacity. Particle size predictions have also been made for different CSSs and speeds. Currently, the operation of a jaw crusher is mainly realized under a fixed set of parameters.
This crusher can be realized in two forms as double toggle and single toggle. Due to its simplicity, lower cost, and its higher efficiency, the single toggle jaw crusher is the most realized form in new applications. Jaw crushers achieve size reduction mainly by compressing particles between relatively slow moving, inclined surfaces.
k is the "size modulus" of the distribution (i.e. k is the maximum particle size, [ P ( k ) = 1] and m is a parameter called "distribution modulus" (slope) of the particle size
Jaw crushers are commonly-used machines in aggregate production. The aim of the research is to present a model which is able to predict particle size distribution in jaw crushers and to provide a new method for effectively controlling the quality of crushed product.

The size of a jaw crusher is usually described by the gape and the width, expressed as gape × width. The common crusher types, sizes and their performance are summarised in Table 4.1.Currently, the dimensions of the largest Blake-type jaw crusher in use are 1600 mm × 2514 mm with motor ratings of 250–300 kW.
The minimum size of the particles that undergo breakage is assumed to be a function of the impact energy and the feed rate.The model predictions are compared with experimental data obtained for ...
