Refining cone, plate segment for a cone ROTARY refiners, conical refiners, a method for manufacturing a set of opposed plates for conical refiners

摘要

1. The refining cone having a working surface, a radially inner end and radially outer end, the working surface including a plurality of bars laterally spaced by intervening grooves and extending through said tapered surface generally outwardly toward said outer end, said plurality of bars curved in the shape of a logarithmic spirali.2. Refining cone of claim 1, wherein the majority of a plurality of knife blades is located on the working poverhnosti.3. Refining cone of claim 1, which has a pattern of bars and grooves arranged in at least two radially distinct zones, wherein substantially all the blades in the outermost zone are curved substantially in the shape of a logarithmic spirali.4. Refining cone of claim 1, which is formed by a substantially conical base and the grinding plate fixed to the base, the plate formed by a plurality of plate segments each of which has a working surface including a plurality of bars being curved with the shape of a logarithmic spirali.5. Refining cone of claim 1, wherein the shape of said blades substantially corresponds to the mathematical expression in polar coordinates in an original xy plane orthogonal to the axis konusaukazannaya curve projected onto the working surface has a shape change according to the following formulas: wherein r - radial position along the centerline knife; a - scale factor for r, and α - intersecting angle between any tangent to the curve and the generatrix of the coordinate system xy, gw1cone and bwcone - the width of the blade and the groove on the cone, gw and bw - bars and grooves width in the original xy
