Economic efficiency

Economic efficiency. In microeconomics, economic efficiency is, roughly speaking, a situation in which nothing can be improved without something else being hurt. Depending on the context, it is usually one of the following two related concepts: Allocative or Pareto efficiency: any changes made to assist one person would harm another.

Six roller mill for higher crushing with better extraction.

Capabilities and limitations are indicated for the Donnelly chute (and 4-roller mill incorporating it), the toothed roll pressure feeder (TRPF) and the grooved roll pressure feeder (GRPF). A 6-roller mill effectively integrates a normal mill with a very-heavy-duty GRPF and a heavy-duty under-feed roller, giving all the advantages of the GRPF plus better feeding and extraction.

Chemical Engineering Stop: Rittinger''s and Kick''s laws

 · Rittinger''s and Kick''s laws. Rittinger''s law states that work required in crushing is proportional to the new surface created. In other words, crushing efficiency is constant and for a given machine and feed material is independent of the sizes of feed and product. Rittinger''s law is written as-. P/ ṁ = Kr (1/Dsb – 1/Dsa) Kick ...
