A simple single press nip is shown schematically in below. The web is squeezed between a solid roll and a felt supported by a perforated roll. The water is expelled into the felt and then into the holes of the perforated roll. The latter may be a suction roll. Suction is applied over the pressing zone

angle must be detected and actions must be taken. Figure 7 Calculated and measured roll angle in extreme driving situation Fig. 7 clearly shows that large peaks in the calculated angle deviate from the measured angle. Methods to identify when the calculated angle is wrong were developed and implemented. When errors
operating a 3 roll bending machine. In particular The use of gloves with fingertips during initial feeding of work pieces should be prohibited because the tips can be caught and drawn into the roll intake. Where there is a genuine need for hand protection palm protection only may be sufficient. Loose fitting clothing should not be worn.

Compare this with the breakage function used for grinding machines. For both standard and short-head Symons cone crushers d1.1 CSS 5.9 d2.2 CSS .
Angle of Nip The angle formed between the moving surface of a crusher roll or jaw plate and the stationary plate surface at which point the material will be pinched. Angle varies with machine size and material lump size. Bond Work Index BWI Kilowatt hour kWh per short ton required to reduce the material to 80 passing 100 microns.
