Screen handling

Following the above-mentioned motivation, precise control over temperatare can be exerted in micro reactors [9,10]. Also, parallel or fast serial screening, handling small volumes distributed over compactly arranged reaction flow-through chambers, can be achieved in micro reactors. 

The code in this book makes use of a suite of subroutines for screen handling that have been developed from those given by Ward and Bromhead [27,28],...

This improved the handling in-situ distinctly. The visualisation is now perfomied by a flat-screen TFT-display, and the keyboard can be fixed as part of the device (Fig. 3). 

Sizing of the cmshed and ground product is a necessary step prior to any mineral processing operation, and in the production of a product having a specific size. Controlling the size of material fed to other equipment is important. AH equipment has an optimum size range of material that it can handle most efficiently. Size separation can be achieved either by screening (for coarser particles) or by classification (for fines) (see also Separation, size). 

Wood Residuals. Chips, sawdust, and other residuals such as planar shavings are used as a primary source of fiber for some pulp mills. Chips are screened and placed in a purchased chip pile. Sawdust and other residuals obtained from wood processing plants must be cooked separately and requite special digesters and handling equipment. These materials may also be burned as hog fuel.
