Effect of ball mill grinding parameters of hydrated lime, The influence of several grinding parameters such as charged material volume, ball filling ratio, and mill rotation speed on energy efficiency of fine grinding of hydrated lime and the product fineness of hydrated lime was studied experimentally using a laboratory scale ball mill
Ball mill shells are often furnished with two manholes. Ball mills – with small balls or cylpebs – can produce the finest product of all tumbling mills. 80% minus 74 microns is a normal requirement from the concentrators. The CRRK series of wet grinding ball mills are tabulated below. PEBBLE MILLS
A ball mill, a type of grinder, is a cylindrical device used in grinding (or mixing) materials like ores, chemicals, ceramic raw materials and paints.Ball mills rotate around a horizontal axis, partially filled with the material to be ground plus the grinding medium. Different materials are used as media, including ceramic balls, flint pebbles and stainless steel balls.

FM 306: SIZE REDUCTION AND SIEVING ... size reduction ratio dDs/Ds n = 2, Rittinger's Law: ... After 40 minutes take out lime stone powder from the ball mill. 7. Fill the lime stone powder to new set of sieves of small sizes. Keep the sieves on the vibrator for 20 minutes. 5. 8. Weigh the mass of lime stone powder retained on each sieve.
The water to lime ratio in the mill is adjusted automatically to maintain a constant slaking temperature based on a temperature probe directly in the mill.Vertical ball mill slakers typically operate between 75 oc and 85 oc, and like conventional detention slakers they can, with good water temperature control and a stable lime supply, be run.
In kraft pulp mills, lime slaker grits and green liquor dregs are the two main waste materials that need to be treated before disposal. Treatment of these waste materials has evolved over time to ...
Ball Mill. The ball mill has two primary functions within the quicklime slaking system; firstly the reduction of quicklime / hydrated lime into smaller particles critical to the correct reaction with process, and secondly provide a rotating vessel to allow majority for the chemical reaction to occur.

C. BALL MILL SLAKERS Ball mill slakers are an adaptation of ball mills, which originally were designed for wet and dry grinding, to lime slaking. Two types of ball mills are used for slaking, horizontal and vertical. Ball mill slakers are generally used where: the capacity required is too large for other types of slakers.
In Grinding, selecting (calculate) the correct or optimum ball size that allows for the best and optimum/ideal or target grind size to be achieved by your ball mill is an important thing for a Mineral Processing Engineer AKA Metallurgist to do. Often, the ball used in ball mills is oversize "just in case".
