This paper presents an optimal control model to improve the operation efficiency of a vertical shaft impact (VSI) crushing process. The optimal control model takes the energy cost as the performance index to be minimized by accounting for the time-of-use (TOU) tariff. The control variables in the developed model are the belt conveyor feed flow ...Web

Given the non-straightforward implication of feed rate on both of these parameters (Fig. 4, Fig. 5), simulations are presented in Fig. 11 to illustrate its effect. It clearly shows a transition in crusher performance in the range of feed rate from about 70 to 140 t/h. Such transition is hypothesized to result from the domination of crushing of ...Web

Feeding impact crushers. Size reduction in an impact crusher relies on energy being conveyed into the rock from the rotor, and it begins with your feed. The initial impact is responsible for more than 60 percent of the crushing action, with the remainder made up of impact against an adjustable breaker bar and a small amount of inter-particle ...Web

The force on the housing decreases largely, with the lowest drop of 11.75% and the highest drop of 27.38%, that is, the feed rate has no obvious impact on the crushing effect, but its impact on the housing wear is more obvious. According to the growth rate values, when the feed rate is 4 m/s, the housing wear is greatly reduced.Web

Control the crusher's feed rate: Controlling it can help optimize its performance by preventing overloading and ensuring a consistent feed. You can do that by controlling the crusher's feed rate by adjusting the size and distribution of the feed material and by using feed control devices such as vibrating grizzly feeders or apron feeders.Web
