The vertical shaft impact (VSI) crusher is a commonly-used machine in aggregate production. A comprehensive understanding of the physical phenomena …

The word impact makes sense that in this particular type of crusher some impaction is being used for crushing of rocks. In normal types of crusher pressure is generated for the crushing of rocks. But, impact crushers involve an impact method. The first Vertical Shaft Impact Crusher was invented by Francis E. Agnew in 1920s.

1. Introduction. Vertical shaft impact crushers (VSI's) are usually used in tertiary crushing stations in both the aggregate and mining industries for crushing hard rock material or ores when a product material with a cubical shape and a number of fines is required [1, 2].A VSI crusher has also been shown to be one of the best options in …

natural sources, like gravel, or manufactured crushed rock. VSI crushers can be used to create this machine sand but existing mathematical models make it hard to plan new …

The impact crusher working principle involves a high-speed rotor that rotates around a horizontal axis. The rotor is equipped with a series of hammers that strike the material as it enters the crushing …

The operating principle of the vertical shaft impact (VSI) crusher is shown in Fig. 2. Rock material falls down into the rotor which rotates so that the edge speed is about 50–60 m/s. The rock particles accelerate and impact the surrounding bed of rock that is formed during operation.

Figure 1.3 vertical shaft shaft impact crusher top view 4 Figure 1.4 Vertical shaft impact crusher front view 4 ... Principle of operation: Feed material drops through the feed tube onto chi shoe table or enclosed rotor which, through centrifugal force throws the material against stationary anvils when the rock

Abstract. 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 …
