Then the circulating load ratio equals
THE CHEMISTRY OF MILK | Dairy Processing Handbook
Milk fat. Milk and cream are examples of fat-in-water (or oil-in-water) emulsions. The milk fat exists as small globules or droplets dispersed in the milk serum, Figure 2.15. Their diameters range from 0.1 to 20 µm (1 µm = 0.001 mm). The average size is 3 – 4 µm and there are some 10 10 globules per ml.
Ball Mills - an overview | ScienceDirect Topics
They have lower specific energy consumption than ball mills and the separator, as in raw mills, is integral with the mill body. In the Loesche mill, Fig. 2.23, 16 two pairs of rollers are used. In each pair the first, smaller diameter, roller stabilises the bed prior to grinding which takes place under the larger roller.
Milling Machine: Parts, Types, Operations, Milling Cutter ...
Milling is the machining process in which the removal of metal takes place due to the cutting action of a rotating milling cutter.In a milling machine, the cutter is rotating due to workpiece is fed against it.This machine can hold more than one tool at a time. The cutter rotates at high speed, and because of the many cutting edges, it removes metal at a very fast rate.

G-Codes Explained: An Introduction to Common G-Code Codes
G-code is the operational language for CNC machining. It tells numerically controlled lathes and machining centers how to move tools in order to perform various cutting operations. It is equivalent to manual programming where each operation is spelled out line-by-line and is separate from M-code and T-code, codes that control the machine and tooling.
Exhaust Gas Recirculation (EGR) complete guide ...
Exhaust Gas Recirculation (EGR) is a system that allows the exhaust gases to be recirculated back into the intake manifold. This process leads to a significant reduction in nitrogen oxides (NOx) emissions because it reduces the two elements underlying its production: oxygen in excess and combustion temperature.
