Fig. 2 shows the timewise evolution of the cumulative PSD experimentally obtained from the laboratory batch ball mill with different single ball sizes (, d B = 20, 30, and 40 mm) using steel balls and alumina balls. As milling progressed and finer particles were generated by breakage, the PSD shifted to the left monotonically even in the fine particle size domain (1100 μm).

All continuous flow grinding tests were performed in a laboratory scale pilot plant, which operates in closed loop and includes a mineral feed hopper, a continuoustype ball mill, a slurry centrifugal pump, and a helical classifier. Briefly, in this pilot plant, the chalcopyrite ore is fed through the hopper and dosed by a vibrating feeder.
Ball mills produce 1 to 50 ton/h power of which near about 70 to 90 percent would pass a 200 mesh screen and the energy requirement of a ball mill is about 16 kWh/t. In the case of the batchoperated mill, a measured quality of a solid to be ground is charged into the mill through an opening in the shell.

mill behavior is a deterministic model (as opposed to a stochastic), which is formulated in terms of a continuous time variable and a discretized size variable. The development of the PBM when considering this approach is briefly described, as follows. Consider the mass of material in a ball mill to be divided into n narrow size intervals with

In all simulations, we set a τ value of 10 min, which was experimentally obtained in opencircuit continuous ball mills [17, 69], and the feed mass flow rate of 10 g/min. In Runs 15, λ value was set as 0 (linear breakage kinetics). The other parameters were obtained from ref. [49]. The solutions of the CSTM model (refer to Eq.
A ball mill is a type of grinder used to grind or blend materials for use in mineral dressing processes, paints, pyrotechnics, ceramics, and selective laser sintering. It works on the principle of impact and attrition: size reduction is done by impact as the balls drop from near the top of the shell.
Also, each ball mill can process only one order at a given time. Ball mills are either continuous or discontinuous. In this study, only continuous ball mills are considered. In a continuous ball mill as opposed to a discontinuous one, loading and unloading occur during the slurry processing with no need of switching it off (Tang et al., 2018).
Project Description. The 1500t/d Pakistan copper mine project uses a continuous copper ball mill for copper mining as the main equipment. The raw ore composition of the project is relatively simple, and the metal minerals are mainly chalcopyrite and pyrite. The main components of nonmetallic minerals are quartz, chlorite, etc.
In this context, modeling of fullscale continuous ball mills could provide significant insights and help process design (King, 2001). Ball milling, where balls hit and grind particles in a rotating horizontal tube, is reported to be an inefficient unit operation (von Seebach et al., 1996, Fuerstenau and Abouzeid, 2002).
