Feed Undersize And Crusher Capacity

Effect of Feed Rock Size Distribution on Crusher Performance

2015-10-22  If the ore feed to any gyratory or jaw crusher consisted entirely of large cubes or spheres of a size that would just barely enter the crushing chamber, the crusher could not be expected to produce anything like its normal rated capacity because the upper part of the crusher could not shatter the large pieces enough to keep the rest of the crushing chamber busy. Such a condition is of course ...

Jaw Crusher - ScienceDirect

2016-01-01  Taggart expressed the relationship between crusher capacity and reduction ratio in terms of a reduction ton or tonne, Q R defined as (4.22) Q R = Q T ⋅ R 80 where Q T is the capacity in terms of actual tonnage crushed per hour. The quantity of feed actually crushed is determined by subtracting the feed undersize from the total quantity of feed.

Crusher - an overview ScienceDirect Topics

When the feed rate is regulated to keep the receiving hopper of the crusher full at all times so that the volume rate of rock entering any point in the crusher is greater than the rate of rock leaving, it is referred to as choke feeding. During choke feeding the crushing action takes place between the jaw plates and particles as well as by inter-particle compression. Choke feeding necessarily ...

2012-01-21  Historically, the capacity of the tertiary crusher has been sufficient to provide a feed to quaternary crushers 1 and 2 and a 36in Hydrocone (quaternary number 3). However, it has been recognized that, as and when the capacity of the plant is increased, the tertiary crusher will become a bottleneck, as the capacity of this machine is restricted to around 220 tonnes/h.

TECHNICAL NOTES 5 CRUSHERS - Mineral Tech

The capacity of the crusher is determined by its size. The gape determines the maximum size of material that can be accepted. Maximum size that can be accepted into the crusher is approximately 80% of the gape. Jaw crushers are operated to produce a size reduction ratio between 4:1 and 9:1. Gyratory crushers can produce size reduction ratios over a somewhat larger range of 3:1 to 10:1. The ...

PQ University Lesson 8- Screening : Pit Quarry

2019-10-11  As feed material is a mixture of varying sizes, oversize material will restrict the passage of undersize material, which results in a build-up, or bed depth, of material on the screen surface. Bed depth diminishes as the undersize material passes through the screen openings. For efficient screening, the material bed should not reach a depth that prevents undersize from stratifying before it is ...
