Embodiment Construction

[0051] exist Figure 7 The exemplarily illustrated arched configuration in includes construction lines with polynomial functions of permutations of the second (A) and third (B). Advantageously, this arched formation is represented by polynomial functions arranged arbitrarily, since these polynomial functions are always continuously differentiable and do not contain discontinuities as in the case of an arrowhead formation at the tip of the arrow .

[0052] exist Figure 8 The arched configuration with eccentric (A) and concentric (B) arched segments pointing towards the crushing gap or pointing away from the crushing gap is shown in . In the case of arching in the direction of the crushing gap, the material is conducted to the edge of the rotor / roller (eccentrically), otherwise to the center (concentrically).

[0053] It is also possible to switch a plurality of arches in a row of teeth in undulating succession in the manner of multiple arches.

Abstract

A crushing tooth arrangement for roller crushers or rotor crushers with improved draw-in, discharge, throughput, crushing and/or wear behavior is provided. The crushing tooth arrangement has rows of teeth of the rollers or rotors that do not have any points of discontinuity and have opposing offset angle courses in the axial direction. Forces are exerted, on the material to be crushed or bulk material fed in, which generate an axial mass flow, which homogenizes an inhomogeneous material distribution fed in along the rollers or rotors. Furthermore, a crushing tooth arrangement is provided, in which the rows of teeth each comprise at least three tooth subgroups arranged in an axially aligned manner each with at least two crushing teeth. The tooth subgroups are offset in an arrow-shaped manner and the rows of teeth are arranged opposing one another. This crushing tooth arrangement is especially suitable for crushing large chunks of material.

Description

technical field [0001] The subject of the present invention is the arcuate and polygonal arrangement (arc and polygonal configuration) of the crushing teeth on the circumferential surface of the rotor or the rollers of rotor mills and roller mills. The tooth height h relative to the rotor diameter or the roller diameter D determines whether it is a rotor mill (shaft mill, screen) with a tooth height to rotor diameter ratio (h / D≥0.17) or a tooth height The ratio of the diameter of the roller to the roller (h / D<0.17) of the roller crusher. Background technique [0002] Rotors and rollers equipped with teeth are used in rotor crushers and roller crushers to improve the inductive relationship And the crushing is made easy by the concentrated force input. The arrangement of the crushing teeth (tooth configuration / crushing tooth system) is of decisive importance here. This affects the introduction characteristics, especially the introduction time for large material pieces, ...
