Teeth for disperser plate having grooves and taper

Abstract

A disperser plate segment for removing contaminants from fiber stock, the segment comprising: radially inner and outer edges, multiple radially concentric rows of teeth, each row of teeth having multiple teeth defining multiple channels disposed intermediate the teeth, each of the channels having a lower channel base surface and each of the teeth having a top surface, at least one face surface extending from the channel base surface to the top surface, and wherein at least one of the face surfaces comprises at least two grooves.

Description

[0001] related application [0002] This application claims priority to US Provisional Patent Application No. 61 / 746,011, filed December 26, 2012, which is hereby incorporated by reference in its entirety. technical field [0003] The present disclosure relates to disperser disk segments. Background technique [0004] Recycled paper and packaging materials are referred to as "fiber stock" by those skilled in the art. Fiber stock usually goes through several processes to remove ink and toner from copy paper. Soils such as plastic are collectively referred to as "stickies" by those in the art. The removal process is not entirely effective, and residual ink, toner and stickies are typically dispersed to avoid stickies from sticking to paper machine parts and causing holes or weak spots in the new paper. Stickies clumping and building up on the paper machine cause idle time, which increases the cost of the manufacturing process. Residual ink particles typically show up as gl...

Problems solved by technology

Adding more teeth generally increases the efficiency of the dispersion process, but the size of the teeth that can be manufactured at reasonable cost limits this number
