The ore is to be broken down in a jaw crusher to pass through a 11.5 cm screen. The undersize is scalped before feeding to the jaw crusher. Assuming the maximum feed rate is maintained at 30 t/h and the shapes of feed and product are the same and the crusher set is 10 cm, estimate the size of jaw crusher required and the production rate. Solution
1. When the jaw crusher is idling, the metal impact sound appears at the lower part. It may be due to the following three reasons: (1) The impact sound between the movable jaw and the fixed jaw tooth plate of the jaw crusher is caused by that the discharge opening is too small, it should be adjusted in time. (2) The impact sound in the …

The grease used in the jaw crusher should be determined according to the place of use and temperature conditions. Generally, calcium-based, sodium-based and calcium-sodium-based greases are used. The grease added into the bearing housing is about 50% of its space volume and replaced every 3 to 6 months.
Measurement of the electricity consumption during crushing was done on a laboratory jaw crusher Bauknecht, Fig. 1. Jaw crusher operates by compressing the feed material between a fixed and a moving jaw back and forth in an eccentric cyclic motion (Cleary and Sinnott, 2015). The feed size of the opening was 110 × 100 mm 2.

The overarching principle guiding jaw crushers is a compression action. A V-shaped alignment houses the fixed jaw, serving as the immovable surface that facilitates the initial breakage. Simultaneously, the movable jaw, in a swinging motion, exerts force on the incoming material, compelling it against the unyielding surface of the fixed jaw.
