Much of the data on which sizing/design curves and tables are based comes from operations involving those two very important types: gyratory and jaw …

He outlines three simple rules behind properly sizing a jaw crusher. Rule #1: Identify maximum feed size. The size of the crusher opening directly determines the maximum feed size going into the crusher. For example, if the jaw has a 30-in. opening (gape), the maximum feed size should not exceed 80% or 24-in. If crusher feed …

Desired product grading. This goes hand in hand with the CSS (Crushing adjustment). You set your crushing adjustments such as CSS accordingly to obtain the desired product grading. For example, …

) 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 ...

Rule 1: Always use a jaw crusher if you can due to lower costs. Rule 2: For low capacity applications, use jaw crusher and hydraulic hammer for oversize. Rule 3: For high …

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.

The results were not as drastic when compared to the Full Cavity test, but clear differences can be seen in Table 1 below. This shows the relative operating condition when compared to the Half Cavity tests. The values in Table 1 show the normalised specific energy in kwh/t used to produce arbitrary product sizes of 13 mm x 0 and 6.7 mm x 0.

The purpose of the primary crusher is to reduce the ROM ore to a size amenable for feeding the secondary crusher or the SAG mill grinding circuit. The ratio of reduction through a primary crusher can be up to about 8:1. Feed: ROM up to 1.5 m. Product: -300mm (for transport) to -200mm (for SAG mill) Feed Rate:

The accompanying table gives typical outputs for our range of machines, based on dry, free flowing material with a crushing work index of 16 and a bulk density of 100 lbs/cu ft (1600 kg/cu m). Product Gradation The curves shown give an indication of the likely product and are based on material of medium hardness with a crushing work index of 16.

A Jaw Crusher is sized so that the maximum feed size is 80% of the gape and width openings. The gape is the measurement between the two jaw dies, while the width is the measurement between the two side plates. For example, if the maximum feed size is 29"x49", the crusher gape would be 32" and the width would be 54".

A characteristic behavior of a cone crusher, is the fact that if the chosen CSS is larger than the minimum CSS, the product curve becomes steeper. In Fig. 21, a hypothetical example of this is shown. The model was applied to a wide size distribution typical for a primary crusher product, i.e. coarse, secondary crushing.
