    10/01/2014· The dry grinding of limestone in a planetary ball mill was investigated as a function of the diameter of the grinding balls and the revolution speed of the mill. The tests were carried out with the same feed size (75 × 250 μm) at variable times up to 240 min.

  • FM 306: SIZE REDUCTION AND SIEVING

    1. Take 5.0 kg lime stone and charge it to the series of sieves to get pre-grinding size distribution. 2. Continue sieving for 10 minutes. 3. Weigh the mass of lime stone retained on each sieve. 4. Load lime stone to the ball mill along with metal balls. 5. Run the ball mill for 40 minutes at the speed 1 rpm. 6. After 40 minutes take out lime stone powder from the ball mill.

  • Ball mill Wikipedia

    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. A ball mill consists of a hollow cylindrical shell rotating about its axis. The axis of the shell may be either

  • Lime Slaking Mill Metallurgist & Mineral Processing

    06/03/2019· A horizontal ball mill can be used as in a lime slaking circuit just as well as a vertimill. Some operations apply the raw quicklime directly to the ore on the belt moving toward further crushing or grinding. In this application, it is necessary only to have a suitable lime storage tank with a live bin bottom and a means for metering the lime from the tank to the ore. Such metering devices may be screw

  • Ball Mills an overview ScienceDirect Topics

    The ball mill is a tumbling mill that uses steel balls as the grinding media. The length of the cylindrical shell is usually 1–1.5 times the shell diameter (Figure 8.11). The feed can be dry, with less than 3% moisture to minimize ball coating, or slurry containing 20–40% water by weight.

  • Limestone Mills Limestone Crushers & Pulverizers

    Williams Direct Injection Roller Mills are used as limestone grinding machines and can grind to very exact particle sizes that are required for efficient SO2 removal. These limestone mills are designed to operate at 3 to 4 PSI (0.2 to 0.3 bar) and 250°F (120°C) to inject the limestone directly into the Circulating Fluidized Bed (CFB), thus eliminating costly material handling, storage, and

  • AN OVERVIEW OF LIME SLAKING AGT Group

    The ball mill slakers are much more expensive than paste or slurry slakers. They are available in sizes ranging from 1000lb/hr to 50 tons/hr. Figure 3 shows an attritor type vertical ball mill lime slaker. The ball mill slakers are equipped with an external classifier, which separates slurry from the oversized grit and impurities. The oversize

  • Ball mills for various applications Gebr. Pfeiffer

    Fed into the mill through one or both bearing trunnions, the material is ground by impact and friction from the balls. The ground product is discharged from the mill through discharge slots provided in the mill tube, through a discharge wall or through the end trunnion. The design and setting of the discharge slots or discharge wall determine the grain size distribution of the ground product. When performing circuit

  • How can one select ball size in ball milling and how much

    31/01/2015· Ball size depends on initial size of charge and ranges from 10mm-150mm dia. For particular material and initial size the ball size must be optimized. Please refer the link below and see if it
