Coarse aggregate weighing 900 g with 26 mm particle size is fed into the jaw crusher, which produces several particle sizes (19, 12.5, 9.5, 4.75, and less than 4.75 mm).The maximum particle size of the product from the jaw crusher depends on the set width of the discharge opening and the stroke of the crusher jaw. However, their estimates from these geometric parameters (Fig. 4.11 ) only provide an orientation, because the properties of the material to be comminuted exert an additional, important influence Processing of Construction and Demolition Waste

Influence of some rock strength properties on jaw crusher
The size reduction of equal weighed of the rock samples was done using Laboratory Jaw Crusher and the particle size distribu- tion was carried out in notional set of sieves using Sieve Shaker. The crushing times were taken and re- corded and the weights of samples retained on the sieves recorded for size distribution.Using a small jaw crusher, the wear of the crusher liners has been studied for different settings of the crusher. The experiments have been carried out using quartzite, known for being very abrasive.

A fundamental model of an industrial-scale jaw crusher
The particle size is reduced in each compression, resulting into finer particle size distribution as the material passes through the chamber. The CSS will affect the product size significantly, and because the same feed was used in both simulations, the reduction of the particle size in Fig. 10 is limited due to the larger CSS.The actual capacity was obtained to be 301 kg/h after the performance evaluation of the machine, and it has a 98 % material recovery rate and 75.25 % machine efficiency.
