grinding mills using acid

What is a Grinding Aid (with picture)
A reduction in energy costs is a notable benefit of grinding aid use. Mills save money and power when using these aids because the aids transform the cement-making process into an endergonic process consuming energy from the surrounding environment.

Grinding of WCrV steel shavings SpringerLink
1. With the aim of using powder for making compact billets and tools the authors studied the grinding of WCrV steel in ball mills and vibromills with addition of surfactants- machine oil and solutions of oleic acid in oil and CCl4. 2. Addition of pure CCl4 retards grinding in comparison with dry grinding. Addition of oleic acid to CCl4 accelerates grinding. The optimum additive was found to

Hydroxy-carboxylic acid grinding aidsKLIMPEL RICHARD R.
Four grinding mills each 13 cm in diameter and 20 cm in length were each filled with 400 g of one cm diameter plain iron balls as media similar to the media used in industrial mills. The mills were then each loaded with 200 g of minus 10 mesh U.S. screen Minnesota iron oxide ore and rotated on a roller bar table drive at 40 rpm for 24 days.

INFLUENCE OF VISCOSITY ON GRINDING IN BALL-MILLS.
on additive grinding. Although the adsorption theory is quite generally accepted other reasons are also suggested for increased efficiency of grinding when additives are used. Von Szantho ( 6 ) in 1949 conducted a series of tests using oleic acid sodium oleate and "Flotigam P" (C12- C14 amine from coconut oil). He claimed up to 120 increase

Variable rake speed is another control used in few mills. Most operators think rake speed is better left alone. If you add acid the pH goes down below 7 if you add an alkali like lime the pH will go up say to 9 or 10 depending on how much lime you add.
