Of course the answer is ultimately feed efficiency producing the most milk eggs meat or fiber at the lowest possible cost Particle size reduction as the first step in the feed manufacturing

In this equation E is the specific energy required for the grind and F80 and P80 are the sizes in micrometers that 80% of the weight passes of the mill feed and product respectively The parameter Wi known as the work index of the ore is obtained from batch bench tests first devised by Bond (1961) The power calculated on using equation 1 (Bond 1961 Rowland and Kjos 1978) relates to

Corrected Ball Mill Feed and 3 T2' the particle size distribution of the Corrected Ball Mill Feed With two equations and three unknowns there are several solutions to equations [5] and [6] depending on the value attributed to the Fines Factor (Q1) each yielding different Corrected Ball Mill Feed Size Distributions (T'2) This is

The particle size distribution produced is governed primarily by the throughput and the amount of media and multiple mill arrangement Primary mill control is by media addition to maintain the required power draw to achieve the desired product Multiple SMDs can be arranged in parallel or series depending on the circuit requirements to affect the particle size distribution

Jet mill working principle How dose a jet mill work? This article aims to describe the working principle of a jet mill A jet mill also called fluid energy mill is used for solid material micronization Micronization is a term used to describe size reduction where the resulting particle-size distribution is less than 10 microns Jet mills are used for micronizing of solids of chemicals

The capacity of each unit size is relative to the required power input for the intended grind however mills have been operated with throughputs exceeding 500 mtph Lower capital cost Vertimill requires a simple and small foundation which means less floor space is required In fact in the same application a Vertimill has 50% less footprint than a ball mill Lower operating cost

Effect of ball and feed particle size distribution on the For maximum efficiency a ball mill should be made of or lined with a porcelain or other very hard surface (so grinding also occurs between the wall and the balls) the balls should be of a range of sizes (to maximize points of contact) the mill should have the correct quantity of balls and the charge should be an optimal amount
