Roll Diameter
A smooth surfaced roll crusher had a roll diameter of 910 mm. Its suitability to crush an ore at 10.0 t/h was being examined. Preliminary examination showed that the kinetic friction factor was 0.36 when the speed of revolution was 33 rpm. The average diameter of particles fed to the crusher was 200 mm and the S.G. of the ore was 2.8.

AMIT 135: Lesson 5 Crushing – Mining Mill Operator Training
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:
TECHNICAL NOTES 5 CRUSHERS
The capacity is a function of size and OSS. Manufacturers publish tables of capacity for their crushers of various size as a function of the open-side set. 5.1.1 Cone crushers Cone crushers are commonly used for secondary, tertiary and quaternary crushing duties. Two variations are available - standard and short head
Crusher Efficiency Calculations
For the 1-in. screen below the roll crusher the capacity has no correction factor and the area needed is 32/2.1 = 15.2 sq ft. To handle the output from a 40 x 24 roll crusher the screen will have to be at least 24 in. wide. Perhaps it will be more effective to use one continuous screen of at least 20.1 + 15.2 = 35.3 sq ft.

On predicting roller milling performance: Part II. The breakage function
Introduction. In roller milling of, e.g., wheat grains, each grain passes through the mill independently of surrounding grains [1], [2]. The breakage patterns for each grain, therefore, depend only on the interaction between the grain's physico-chemical properties (size, density, hardness, etc.) and the roller mill design and operation (roll diameter, …
