Cxv. a Wet-crushing Mill for Micro-organisms

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 ...

Modeling and Control of Coal Mill

The paper presents development and validation of coal mill model (including the action of classifier) to be used for improved coal mill control. The model is developed by using the mass and heat balance equations of the coal mill. Genetic Algorithm is used to estimate the unknown parameters that are used in the model validation. The advantage is that the raw data used in modeling can be obtaine...

Removal of Color of Pulp and Paper Mill Effluent by Adsorption on Coal Fly Ash

The present study was conducted for the removal of color of pulp and paper mill effluent using coal fly ash as an adsorbent. The effect of adsorbent dose and pH on color removal has been determined. 100 % color removal was achieved when adsorbent dose was 2.4 gm or more and at pH 6.8 and above.

Crushing analysis of the industrial cage mill and the laboratory jaw crusher

Many research studies have been conducted on the liberation of locked minerals using a crusher and comparing this device with the other devices. This paper reviews the liberation of middle coal by different methods of crushing force. In the Tabas coal washing plant, particles of 0.5-50 mm size are processed through the heavy media method (using 3 Tri-flo separators) and particles of 0-0.5 mm si...
