2.2. Samples analysis after comminution2.2.1. Particle size distribution. The gold ore sample of 200 kg was first fed to the primary crusher (PEX-150 × 250 mm) and secondary crusher (XPC-60 × 100 mm) to ensure all the sample could pass through a sieve of 20 mm.The comminuted ore was then thoroughly mixed and divided, fed to the …
Another possibility is to include other jaw crushers to assess the effect of crusher geometry. 5. Conclusions. The full-scale parameter study allowed for a range of feed material sizes, reduction ratios and crusher operation parameters to be combined. The subsequent quality assessment was conducted using laboratory tests for particle …
I have an old Union Iron Works jaw crusher that we're trying to get back into service. It came with a 3 phase 15 HP electric motor and we're not sure which direction the crusher flywheel should rotate. Looking at the crusher from the side, with the jaws on the right and the motor on the left, should the crusher flywheel rotate clockwise or ...

Bridging can cause a significant loss of production that oftentimes goes unnoticed. It is relevant to keep an eye on bridging in the feeding area of a primary crusher as it can take several minutes to resolve the issue (big rock being removed, fragmented or directed to the chamber). If …
For example, a 32 x 54 sized jaw crusher will measure 32 inches from the movable to stationary jaw (when measured at the top i.e. the opening), and each jaw will have a 54-inch width. If a jaw crusher is rated by jaw plate size, a suitable rating maybe 600 x 400, which indicates a 600 mm by 400 mm jaw plate dimension.
All jaw crushers reduce large sized rocks, ore, or other material by a compression action. A fixed jaw, mounted in a V-shaped alignment, is the stationary breaking surface, while a movable, "swing" jaw exerts force …
