A performance model for impact crushers

Abstract. In this paper we develop a performance model for impact crushers. The product size distribution is obtained as a function of the crusher’s rotor radius and angular velocity, the feed rate and the feed size distribution. The model is based on the standard matrix formulation that includes classification and breakage matrices.

DESIGN AND ANALYSIS OF A HORIZONTAL SHAFT

2011-5-10 · HORIZONTAL SHAFT IMPACT CRUSHER Here the feed material is crushed by highly rigorous impacts originating in the quick rotational movement of hammers/bars fixed to the rotor. The particles are then crushed inside the crusher as they collide against crusher parts and against each other, producing finer, better-shaped product.

Mathematical modeling of a vertical shaft impact

Model parameters such as K 3 and T 10 were found to be particularly influenced by key operational variables such as feed rate and rotor frequency. The significant effect of feed rate on the performance of the VSI crusher studied has been discussed on the basis of simulations of the material flow pattern inside its feed distributing system, simulated using the discrete element method.

2004-12-10 · In conclusion, we have developed a phenomenological model for impact crushers that is able to predict the crusher's performance at steady state and contains a reasonable number of parameters. The specific behaviour of the impact crushers is accounted for through the incorporation of a new classification function that explicitly depends on the average impact energy per unit mass, the rotor velocity

Impact Crusher. The three types of crushers most commonly used for crushing CDW materials are the jaw crusher, the impact crusher and the gyratory crusher (Figure 4.4).A jaw crusher consists of two plates, with one oscillating back and forth against the other at a fixed angle (Figure 4.4(a)) and it is the most widely used in primary crushing stages (Behera et al., ).
