— 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
4 — Cause The quality of the oil is poor or the oil is insufficient; the bearing is damaged; the ambient temperature is high there is no cooling water or the cooling water pressure is low; the cooler is clogged Solution change oil or refuel; change bearings; supply cooling water or increase the pressure of cooling water; clean the cooler 2

Continuous action is created making it faster than the jaw crusher with less power usage Often smaller and more expensive than a jaw crusher gyratory crushers are suitable for larger amounts of materials when a more uniform shape is desired Changing the distance between the rollers allows you to control the desired material output size
WhatsApp
— Additionally jaw crusher feed should be pre screened using a grizzly screen prior to crushing to remove material finer than the closed side setting Setting jaw crushers Ideally the reduction ratio of a jaw crusher should be 6 to 1 There are different ways to calculate reduction ratio but the best way is something called the P80 factor
WhatsApp
— The data presented here is limited to a single rock type and a single jaw crusher A natural continuation of this research would be to extend the test programme to include several rock types of varying strength and brittleness Another possibility is to include other jaw crushers to assess the effect of crusher geometry 5 Conclusions
