Reduction ratio is often measured by dividing the F80 by the P80. The F80 is the particle size where 80% of the feed material is smaller than that size. The P80 represents a particle size where 80% of the product is smaller. Reduction ratios will vary with each application within each family of Hammermills and by the amount of applied energy.
EXAMPLE 11.1. Grinding of sugar Sugar is ground from crystals of which it is acceptable that 80% pass a 500 mm sieve(US Standard Sieve No.35), down to a size in which it is acceptable that 80% passes a 88 mm (70) sieve, and a 5-horsepower motor is found just sufficient for the required throughput.

Grinding is a random process and is subjected to the laws of probability. Grinding steps: i. Primary (Coarse) grinding (generally a rod mill is used)(Feed size as large as 50 mm, product size as fine as 300 microns)(1000 microns = 1 mm) ii. Secondary (Fine) grinding (generally a ball mill is used)(Feed size as large as 0.5 mm,
Size reduction ratio defined as the ratio of initial weight mean diameter of the feed to final weight mean diameter of the product after grinding was also calculated.

Grinding equipment Both roller mills and hammermills have been applied to the task of particle size reduction or grinding in feed milling applications. Hammermills have traditionally been used to produce the finer grinds commonly used for pelleting and for many mash (meal or non-pelleted) feed applications as well.
Grinding – Ex. 1-1 • You are grinding a steel, which has a specific grinding energy (u) of 35 W-s/mm3. • The grinding wheel rotates at 3600 rpm, has a diameter (D) of 150 mm, thickness (b) of 25 mm, and (c) 5 grains per mm2. The motor has a power of 2 kW. • The work piece moves (v) at 1.5 m/min. The chip thickness ratio (r) is 10.

Fig. 11 shows the results of the grinding of a feed of various sizes at a size reduction ratio of 45:1 using a 1 m diameter mill. It can be seen that the optimum portion of the 50.8 mm balls decreases slightly as the value of N 1 …
p – Size reduction ratio • Coarse grinding has RRs below 8:1 • Fine grinding can exceed 100:1 • Grinding of coarse particles in which the increase in surface area per unit mass is relatively small, Kick's Law is a reasonable approximation • Rittinger's law
A cage mill is a versatile machine that applies high-speed impact forces to crush, grind, or pulverize a broad array of abrasive and nonabrasive friable materials – both dry and wet – to a specified fineness. The mill can achieve a size-reduction ratio (the ratio of feed particle size to final product particle size) as
movable plate) with increasing number of pins from inner to outer row (8, 13, 16, 19, and 24 respectively) as shown in Fig. 2. (a). Pin mill have a higher energy input than that for hammer mill and can generally grind softer materials to a finer particle size than that of hammer mill, while hammer mill performs better on hard or coarse ...
Ball Mill Grinding media. Tumbling Mills. Standard Chrome Plated Steel Grinding Media Factors influencing the size of product 1. Rate of feed.
