Crushing rolls might, logically, include roll crushers of the sledging type, the name, by popular usage, is restricted to the double-roll machine (with either smooth or corrugated shells) which crushes entirely by pressure between the surfaces of the roll faces. The sledging type of either single or double-roll arrangement is usually differentiated by such titles as “roll crusher” or

Four roll type teeth crusher is actually made up of two double roll teeth crushers. Teeth roll crusher is outstanding for its large crushing capacity. In addition, the hydraulic coupling with limited distance connecting the motor and reducer prevents overload and the overload protection sensor device makes the machine safe and reliable. Learn

rewind shaft must increase at a linear ratio, relative to roll diameter, as a rewind roll increases in size, through a machine run, to keep tension constant. Tension in the unwind and rewind zones is very dynamic. Roll diameters are constantly changing, so torque and speed must be constantly adjusted relative to changing roll diameters.

The second section of the paper machine is the press section, which removes much of the remaining water via a system of nips formed by rolls pressing against each other aided by press felts that support the sheet and absorb the pressed water. The paper web consistency leaving the press section can be above 40%.

The paper passes through one nip (2 steel rolls) or 2 nips (2 steel rolls separated by a fiber roll) in which rolls are driven independently and speed variation may be from 10 to 30%. Brush Calendering : The paper is pressed against a cylindrical brush by a backing roll

Angle iron works extremely well when used conjunctively. By welding pieces together at 90 degree angles and bracing the angles of the welds with short pieces at 45 degree angles, Airon''s susceptibility to twisting is greatly reduced. That means Airon is a sound and solid material to use for the framing of: crates and boxes cages

Down machine from the suction roll, and at a lower elevation, is the wire turning roll. This roll is driven and pulls the wire around the loop. The wire turning roll has a considerable angle of wrap in order to grip the wire. Supporting the wire in the drainage table area are a number of drainage elements.

Following are some practical ways in which machine designers and users have chosen to apply vacuum rolls. 1. Transporting Wet Webs This takes advantage of single side contact, and is a traditional application for vacuum rolls. In this case, a nip roll or “S” wrap simply cannot be used because the web is wet on one side.

Nip angle The nip angle is the angle between the fixed and movable jaw dies. Too large a nip angle reduces the capacity and increases the wear as the feed material grinds and gouges the jaw dies in an upwards direction during the compressive stroke of the pitman.
