The crushing test was performed by compressing each individual RCA particle between two rigid platens at a constant rate of 1 mm/min until the particle broke into two or more pieces. A minimum of 35 crushing tests were carried out on each shape group. The particles were laid on their longest dimension and the vertical distance …
Chrome Ceramic are chrome bars with ceramic applied through the bar. As with any chrome bar, they do no perform well in applications with tramp metal or large feed sizes, but they are effective in highly abrasive applications. For this reason, chrome ceramic blow bars are often used in secondary and tertiary crushing including asphalt …

There are two crushing machines available; a jaw-crusher and a disc-pulverizer. Samples are usually run through the jaw-crusher first, and then the pulverizer. If the sample is pebble sized, it is only crushed in the pulverizer. Each machine is cleaned thoroughly after use to avoid sample contamination. Once the sample has been crushed, it can ...

With the ceramic inserts on the wear face, the working life of the martensitic blow bars can be largely increased. Normally, the martensitic/ceramic blow bar has twice as much wear life as the pure martensitic blow bar. This material is commonly used in recycling industries and primary crushing in quarries. Certain applications are unsuitable ...
Impact crusher blow bars (also called hammers) are the main wear item of horizontal shaft impact crushers and a major cost driver. The purpose of blow bars is to strike material entering the crushing chamber and throwing it against the impact wall causing the material to fracture into smaller particles (see also: how does an impact crusher work).In the …
