a) Maximum Feed Opening — 625MM (25 In.) b) Recommended Product Range — 100MM to 19MM (4 In. to ¾ In.) Short Head (Tertiary) Cone Crusher (Refer to Fig. 2): The Short Head Cone crusher is normally applied as a third stage crusher in plants designed for three or four stages of crushers.

Below are suggested speed guidelines for CMB Cone Crushers: Low speed: Secondary applications, after a Jaw Crusher. Medium speed: Gravel applications with coarse feed. Standard speed: Tertiary applications (0 x 1/2") High speed: Sand applications (4m or less) Speed ranges: Smaller head diameters (48" or smaller): 750-1,200 rpm.

Maximum feed size varies with each model, but is generally limited to around 600–900mm. The output gradation of the primary HSI crusher is generally coarser than the primary breaker due to the lack of …

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".

Birdsboro Size:–56" x 72". Type-C. Double Toggle Type. 400 HP. both with Amsco as the liner supplier. The rated capacity at 5" closed-side setting was 490 stph based on standard 100lbs/ft3 feed material. These crushers were fed a very fine ore over a 4″ grizzly which allowed the 1000 TPH the SAG mills needed.

Most cone crushers have a feed opening size of 5-14", so material that's larger than the maximum size allowable will need a first stage of crushing before they can be fed into a cone crusher. Final Product Isn't Uniform. Cone crushers do an excellent job of providing finished material that's relatively homogenous.
