This paper discusses the effect of grinding time on the production of submicron dolomite by using the impact and abrasion technique of high energy planetary ball mill. It is known that grinding process leads to surface activation other than exhibiting particle size reduction. Most of the energy applied during the process will be dissipated as heat that could lead to harmful effects to the ...

Thus in order to study the detrimental effects of grinding towards submicron dolomite, sample was ground at 400 rpm speed with various grinding time; 0.5h, 1h, 2h, 5h, 10h and 20h.

The influence of grinding size of the main cereal of the diet on production and egg quality traits was studied in brown hens from 33 to 65 wk of age. The experiment was completely randomized with 6 treatments arranged as a 3 × 2 factorial with 3 main cereals (barley, corn, and wheat) and 2 grinding …

The size effect is a well known phenomenon in grinding. The specific energy increases with decreasing depth of cut. A comprehensive explanation is therefore required to explain the size effect. In this paper, the size effect in grinding is reviewed and the proposition investigated that the size effect correlates with chip surface area.

Biogas technology solves the problem of energy crisis. Biogas is a renewable and environment friendly fuel (Franthena, 2015). This study aims to determine the optimum value of grinding size variations in biogas production with the solid state anaerobic digestion (SS-AD) method of biogas production from rice husk waste. We divide the method used into four stages, namely, the testing phase of ...

1. All particulates collected on the sampling media were created from the grinding activities performed by the subject. 2. All samples sent to the lab for analysis will be accurately evaluated per the chosen sampling method. 3. The base metal has even distribution of the contaminants. 4. The study is being conducted under a worst case scenario.
