The size of a jaw crusher is measured by the top opening of the crushing chamber. For example, a 48" x 42" jaw crusher measures 48" from one crushing jaw to another and is 42" across the width of the two crushers. The primary applications for using jaw crushers are: Crushing different kinds of ore; Reducing building rubble to pieces
1.) Obtaining the size or surface area required for the use of the ore or material. 2.) Allowing ease of transportation and storage. 3.) Separating the different minerals contained within the ore and to release them from one another. 4.) Obtaining the size or surface area required for the enrichment stage.
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.
A primary jaw crusher is a machine designed to reduce large rocks into smaller rocks, gravel, or rock dust.
