Each cavity level was operated as a separate test for a minimum of 30 seconds at constant cavity and power draw levels (+/- 3%) in order to obtain accurate capacity and power draw information. The cavity level was controlled via a manual variable speed drive feed conveyor and visual verification of the cavity height at one of three levels.

High speed crusher that used high speed impact to effect particle reduction. ... The power draw of the crusher dropped significantly as the speed decreased resulting in a lower kW/t specific energy through the machine. There was a major shift in reduction through the machine ' ...
May 01, 2017· Power draw of the crusher when varying the speed and CSS, not considering any mechanical losses. In Fig. 13, it can be observed that the maximum capacity is obtained at slightly above 200 rpm. The capacity will increase with increasing CSS, which is expected because the larger the opening is, the more material that will be let through.

predicting the crusher power draw. Recently Anderson (Andersen, J.S & Napier-Munn, T.J., 1988) predicted crusher power draw using a single regression equation relating the power actually drawn by the industrial machine in producing a particular product size distribution, to the calculated power required to achieve the same size reduction in a ...
Apr 16, 2021· CRUSHER SPEED. The influence of crusher speed, or gyrations of the cone head per minute, is not as well defined as stroke. Depending on the crushing stroke, the CSS and the crushing chamber profile, the effect of increased speed can either increase or decrease the production rate of the crusher. ... power draw and inducing a bowl float or ...

One of the best places to start on the optimization of individual machines is with manipulated variables like the CSS or speed. Sometimes controlled variables such as power draw can be used to manipulate crusher CSS and, lately online product gradation analyzers have been used to control crushers, aiming to stabilize their performance.
The power draw of cone crushers, used in comminution and aggregates production, is in most cases monitored with too low sampling rate in comparison to the operating speed. This does not give adequate information on the actual operation mode and performance of the crusher during a full rotation of the eccentric motion of the mantle, leaving variance in the power draw unnoticed.
Crusher Performance Modeling. H-E Parts ™ software is used in conjunction with their ChamberVision™ software to develop modified crushing cavities to satisfy specific customer targets. Depending on customer requirements, liner profiles can be changed to improve wear life, reduce power draw or increase tonnage.
