Summary of Test Method 4.1 A small laboratory jaw crusher with a feed opening of about 100 by 150 mm (4 by 6 in.) is modified to

Method for adjustment of jaw crusher toggle block,

A jaw crusher is a typical crushing machine that can be used for the primary breaking of rocks as excavated. An example of a double toggle jaw crusher is shown in FIG. 3. Excavated rocks are scooped into the crushing cavity 12 formed between the fixed jaw 1 and the swinging jaw 11, and are broken by the impelling force of the swinging jaw.
