Embodiment Construction

[0026] The drawing shows a roller press as an embodiment of a high-pressure roller mill. In this exemplary embodiment, the high-pressure roller mill is used for grinding material, for example ore-containing material. It is particularly preferred here that it is a concentrate (for example iron ore concentrate), which may also have a relatively low flowability due to its moisture.

[0027] The roll press has a press stand 1 and two rolls 2 arranged adjacent to each other in the press stand 1 , between which a roll gap 3 is formed. The two rolls 2 are rotationally driven in opposite directions by drives not shown. Arranged above the roll gap 3 is a feed hopper 4 through which material is supplied to the roll gap 3 . In the present exemplary embodiment, the feed hopper has at least two opposite hopper walls 4a, each of which is inclined at an angle α towards the vertical, so that the feed hopper 4 has a cross-section that widens from top to bottom. The (negative) angle α can he...

Abstract

What is concerned is a roller press for comminuting, compacting or briquetting material, in particular ore-containing material, having a press frame (1), two rollers (2) arranged next to one another in the press frame (1) with the formation of a roller nip (3), and a feed shaft (4) which is arranged above the roller nip (3) and via which the material can be supplied to the roller nip (3), whereinthe feed shaft (4) has one or more shaft walls (4a) which are oriented vertically or at an inclination to the vertical so as to form a cross section which is constant over the height or widens from top to bottom, and wherein the feed shaft (4) is provided with a measuring device (5) for determining the filling level of the material in the feed shaft (4). This roller press is characterized in thatthe measuring device (5) is designed as a gravimetric measuring device.

Description

technical field [0001] The present invention relates to a roller compactor for crushing, compacting or agglomerating materials, [0002] It has a press stand, two rolls arranged next to each other in the press stand forming a roll gap, and a feed hopper arranged above the roll gap, via which feed hopper the material can be supplied to the roll gap, [0003] wherein the feed hopper has one or more vertically orientated or obliquely oriented hopper walls with respect to the vertical, thus forming a cross section that is at least partially constant in height or widens from top to bottom, [0004] Wherein, the feed hopper is provided with a measuring device for determining the filling height of the material in the feed hopper. Background technique [0005] Such roller presses are particularly preferably high-pressure roller mills, which are preferably used for comminuting materials. However, the invention also includes roller presses or high-pressure roller mills for compactin...
