The article provides the description of production experiment carried out at a mill for varietal grinding wheat into baking flour, technological scheme which selection pasta grits. To obtain statistical set data, was organized 10 days, during values studied process parameters were recorded every two hours. output grits chosen as this. These products are subjected to thorough sorption on sieves ...

FOR some years we have been engaged on the problem of extracting enzymes from micro-organisms. It is well known that most bacteria and yeasts carry out oxidations and metabolic processes at a rate incomparably higher than that of animal tissues. The peculiar virtue of micro-organisms as the source of enzymes is therefore self-evident. A certain amount of success has been attained in extracting ...

The Al-alloying treated tungsten carbide (WC)-Co tool was subjected to grinding using a jaw crusher and planetary mill followed by three wet chemical treatment steps to establish an effective recycling process for WC scraps, especially those generated as bulky and hard scrap. This alloyed WC tool was readily ground to a powder of 1 mm or less and divided into two portions that were 150 μm in si...

The aim of the study was to investigate distribution, enrichment and accumulation of heavy metals in soil and Trigonella foenum-graecum (var. Pusa Early Bunching) after fertigation with paper mill effluent. Doses of paper mill effluent viz. 5%, 10%, 25%, 50%, 75% and 100% were used for fertigation of T. foenum-graecum along with bore well water (control). The results revealed that paper mill ef...

The International Rice Research Institute (IRRI) Test Tube Mill and the Kett ”Pearlest” Polisher were evaluated in terms of milling performance in comparison with a McGill No. 2 Mill. Degree of milling (DOM), evaluated in terms of percent bran removal (the percentage of weight lost during milling) from brown rice, and whole kernel yield (WKY) were compared using sample lots of medium– and long–...

Healthy men produce an enormous number of sperms, far more than necessary for conception. However, several studies suggest that semen samples where the concentration of sperms is below 40 mill/mL may be associated with longer time to pregnancy or even subfertility, and specimens where the concentration of sperms is below 15 mill/mL may carry a high risk of infertility. Historic data from the 19...

on to a heavy wooden mill which is revolved by the bulls moving in a circle round the mill. The old man was bending over the crushing blocks to remove sugar-cane debris when his long hair got undone and was caught in the mill. The bulls continued to move round in a circle which resulted in his hair being wound into the mill. He was dragged round the mill and fruitlessly tugged to get free. His ...

A first principles model of a cement grinding circuit is developed for the purpose of multi-variable model predictive control (MPC). The model is based on a series of mixed flow reactors with an ideal screen to model flow between the two chambers in the ball mill. The separator is modelled by efficiency curves. Breakage of the particles is modelled as a first order process in terms of functions...
