Embodiment Construction

[0024] figure 1 The roll crusher is shown in longitudinal section, which is designed as an eccentric roll crusher. The roller crusher comprises a crushing roller 1 and a movable screening device 2 arranged such that it is inclined above the crushing roller 1 and provided for separating feed particles into coarse 3 and fine 4 particles. The fine particles 4 pass directly through the sieving space without further crushing, while the coarse particles 3 are fed into the roller gap 5 between the crushing roller 1 and the rocker arm 6 .

[0025] The exemplary embodiment relates to an eccentric roll crusher, wherein the crushing roll 1 is arranged eccentrically so as to be freely rotatable on a drive shaft 7 .

[0026]A circumscribed circle B is defined due to the eccentric movement of the crushing roller 1 , which reciprocates so as to oscillate in an eccentric manner. Due to the reciprocating movement, the spacing between the crushing roller 1 and the rocker 6 is also changed. W...

Abstract

The invention relates to a roller crusher, in particular an eccentric roller crusher, comprising a rotatable crusher roller (1) and a moveable device (2) which separates by screening. According to the invention, said device (2) which separates by screening is supported on one side, on a stationary abutment (8) and on the other side on at least one supporting surface (9) of the crusher roller (1). The movement of the crusher roller (1) causes the device (2) which separates by screening and which is supported on the supporting surface (9) to vibrate.

Description

technical field [0001] The invention relates to a roller crusher with a rotatable crushing roller and with a movable screening device. The screening device is arranged upstream of the crushing roller in such a way that the material to be comminuted is initially directed via the screening device and then towards said crushing roller. The screening device is provided for separating the fed material to be comminuted into coarse and fine particles. Once they have the desired size, the fine particles passing through the openings of the sieving device can be conveyed away directly or comminuted in a separate crushing gap. However, the coarse particles retained by the sieving device are comminuted in a known manner by crushing rollers. Background technique [0002] The invention can be realized by various design embodiments of the roll crusher. An eccentric roll crusher with an upstream screen is known from WO 2007 / 019146 A2. The screening device is located upstream of the crus...
