Ore Blend Grinding at HPGR and Ball Mill. The ore blend was ground in a pilotscale HPGR (1 m diameter × m width) at a maximum feed rate of 50 t/h. The ground product was recirculated to the HPGR feeding hopper five or seven times, wherein every recirculation steps a sample was gathered for moisture and size distribution measurement.
Most of the highgrade hematite iron ores are typically subjected to simple dry processes of crushing and classification to meet the size specifications required for direct shipping ore (DSO). This involves multistages of crushing and screening to obtain lump (− + mm) and fines (approximately − mm) products.

is proposed. The jig tails are crushed to 5 mm and fed to ball mill for grinding. Ball Mill: The 5mm size material will be fed to a ball mill, wherein the ore gets ground to approximately 200 microns size with maximum 1 mm size. The ground material will be sent to the series of HydroCyclones, comprising 5" HydroCyclone and 10" Hydro ...
Typically, HPGR (highpressure grinding rolls) and ball mills are used to improve the SSA value of iron ore concentrate [8, 9]. This operation reduces particles size from nearly 1 mm to finer than ...
Important advances have been made in the last 60 years or so in the modeling of ball mills using mathematical formulas and models. One approach that has gained popularity is the population balance model, in particular, when coupled to the specific breakage rate function. The paper demonstrates the application of this methodology to optimize solids concentration in ball milling of an iron ore ...

The grinding setup refers to the socalled Malmberget method used at LKAB, characterized by a subsequent circuit of rod and ball mill grinding. The highest P 80 values were obtained by grinding only in the rod mill for 10 min (step A). Ball mill grinding for 25 min (step B) and 35 min (step C) gave a very narrow range of P 80 values.
The choice of grinding circuit is based on the density and hardness of the ore to be ground. Although use of the rod or ball mill grinding is quite common, a few facilities use autogenous or semi autogenous grinding systems. Autogenous grinding uses coarse pieces of the ore itself as the grinding media in the grinding mill.

The iron ore fines were ground to below 150 μm using a laboratory ball mill (2 ft. x 2 ft) in closed circuit grinding. The particle size distribution of ground iron ore fine and slime samples were carried out by wet process using standard sieves (Table 1). It is observed that 95% of the slime particles are below 45 μm.
