Crusher Design. The approximate capacity of a jaw crusher for hard rock application at a typical setting may be obtained by multiplying the width by 10 to get tonnes per hour. For example, a 48 by 60 crusher will have a capacity in the order of 600 tph when crushing ore in a hard rock mine. Source: Jack de la Vergne

The rock breaks and falls out the bottom. These types of crushers are usually applied as tertiary or quaternary crushers with less than 2" (75 mm) feed or smaller. Some Vertical Shaft Impactors can be used as secondary crushers with larger feed. Vertical Shaft Impactors are very application-specific. They are sensitive to abrasive materials ...

Deck boards are commonly referred to by their nominal thickness and width, such as the most common size, 1x6. The actual thickness may be ¾ - 1" net by a net width of 5-¼" to 5-½". The most important thing, however, is that the board you've selected is approved by your local municipality. Other common nominal sizes are 1x4, 2x6 and 2x8.

crusher capability is based on the top size in feed, maximum allowed reduction ratio, power rating, chamber type, etc. [17]. After the mining operation (blasting, drilling, etc.), the rock material is

production is concentrated to jaw crushers and cone crushers. 1.1.3.2 Process Flow The process flow described in figure.. is a typical process flow built up by a primary crushing stage, secondary crushing stage. The primary stage usually has a jaw or a gyratory crusher and screening equipment.

A-Z Guide to Screening Ore, Rock & Aggregate. A simple definition of a "screen" is a machine with surface (s) used to classify materials by size. Screening is defined as "The mechanical process which accomplishes a division of particles on the basis of size and their acceptance or rejection by a screening surface".

) Calculate the amount of re-circulating load to the crusher, by referring to the applicable table. Example a) Wi=14 curve selected in above table. b) 5 mm sand required. c) Table A1 indicates a 30% breakage ratio at 5mm. d)Product required at the rate of 100 TPH. e) Total throughput of the crusher = Product TPH (100) x 100 / 30 (% breakage ...
