Modeling of an industrial double-roll crusher of a urea
The breakage parameters needed for the complete representation of the crusher are fitted using industrial data from a plant of high capacity (1 million tons of granulated urea/year). In order to predict the performance of the crusher, the particle size distribution of the feed (oversize fraction) and the gaps settings are the only required inputs.Evertsson and Bearman (1997) presented a selection function with the compression ratio as the input parameters, and the influence of particle size distribution of feed was indicated by Evertsson (2000) with the inter-particle breakage experiment, and then the product size distribution of a full-size cone crusher can be predicted.The improved model of inter-particle breakage considering

Modeling and Improving the Efficiency of Crushing Equipment
The most important functions of the digital system for the crusher are the continuous monitoring of the equipment, crusher machinery, and aggregates during operation and the signal generation for crusher capacity control. The crusher is electronically archived with all failures and operating parameters.During the sand-making process, the wear of the split cone will affect the dynamic balance of the rotor and the sand-making effect of the crusher. This paper focuses on experiments and simulations with the rotor of a vertical shaft impact crusher. A wear model for predicting the wear value of the split cone is established and its effectiveness Wear Law and Parameter Optimization Study on the Split

What Is A Jaw Crusher MEKA
WHAT ARE THE MAIN COMPONENTS OF JAW CRUSHERS? / PARTS AND MAIN PARAMETERS OF JAW CRUSHERS. Jaw crushers are generally defined by their opening size. For example, a 900x650 mm crusher refers to a crusher with an inlet measuring 900 mm by 650 mm. The main parts and main technical parameters of a jaw crusher are location of the crusher in a mine imposes a number of requirements on its design and parameters; primarily they are related to overall dimensions and explosion safety issues. One of the promising options is using single-roll gyratory crushers [2]. Figure 1 shows a cross section of the working chamber of such a crusher.

Improved flow- and pressure model for cone crushers
Simulation results show that the new flow model has improved the accuracy in the prediction of operating parameters of the rock crusher, such as hydraulic pressure, power draw, and close side setting, CSS. There is also some improvement of the prediction of worn geometry as compared to the old model.Simply put, the breakage parameter b of Equation 1 determines the amount of fines in the product. In Fig. 4, an example is shown where a feed curve was broken to various products where the breakage parameter b was altered between 1.5 and 4, while the x50 and x100 parameter were here kept constant, relative to the CSS..
