A lump of lead, whose dimensions are greater than the gap of the crusher, is lowered through the crusher while the crusher is running. The lead is pulled back through the crusher very slowly to be sure that it is flattened as far as it can be. The narrowest point on the lead is then measured. This will be the SET POINT of the crusher.
Fig. 2 b shows a large gyratory crusher processing run of mine ore to 100150 mm followed by two stages of cone crushing to generate a P80 of 612 mm which could be fed into a large ball mill operating in closed circuit with hydrocyclones. By using multiple process lines, these circuits could process up to 100,000 tonnes of ore per day.

Here, all the objective functions and constraints are not only function of decision variable set X, but also two sets of parameters, denoted by τ, ω.The parameters indicate the following: ball mill and rod mill grindability indices— τ 1 τ 2, primary and secondary cyclone sharpness indices— τ 3, τ 4, ball mill and rod mill grindability exponents— τ 5, τ 6, and finally four size ...
The primary crusher product P80 size was assumed to be 200 mm and the specific energy required to reduce the ore to the target 200 µm size was calculated for crushers, rod, ball, sag mills, and ...
The process of ball milling and the materials that compose planetary ball mills are highly complex, and the existing research on the change in ballmilling energy is not mature. The theoretical model of a ball mill was established for the first time to simulate the motion, collision process, energy transfer, and temperature change of small balls during the ballmilling process. Furthermore, by ...
Fladvad and Onnela [] studied the influence of jaw crusher parameters on the quality of primary crushed the hammer crusher (Figure 2), hammerheads of high wear resistance and strength are attached to the tip of a rotor placed inside a wellsealed, noiseless, and fixed the hammerheads rotate with a high speed, they will produce a high impact on the glass breaking them ...
A cone crusher is a machine that crushes rock materials with high efficiency and low power consumption; it is one of the typical road construction equipment. To improve the production efficiency, mechanical performance, and crushing performance of the cone crusher, thus increasing profit, this study used Discrete element method (DEM) particle analysis software to optimize the structure of the ...
