Definitions
- the invention relates to a roller mill with edge elements for comminuting granular material and a method for operating a roller mill.
- Roller mills are usually used to crush grist, such as limestone, clinker or similar rocks.
- grist such as limestone, clinker or similar rocks.
- edge elements In order to influence the lateral outflow of ground material from a grinding gap formed between the grinding rollers of a roller mill in a controlled manner, it is known to arrange edge elements on one of the grinding rollers.
- Such a roller mill with edge elements is, for example, from DE 20 2014 006 837 U1 known. An increased specific grinding pressure acts on the edge elements, which leads to a high load on the edge elements and thus often to wear or breakage of the edge elements.
- WO2013/156586 A2 shows a roller mill with edge elements according to the preamble of claim 1.
- a roller mill for comminuting granular material comprises a first grinding roller and a second grinding roller, which are arranged opposite one another and can be driven in opposite directions, with a grinding gap being formed between the grinding rollers.
- At least one of the grinding rollers has an edge element on an end region of a grinding roller end, which is designed in such a way that it extends across the grinding gap and at least partially covers the opposite grinding roller at the front.
- a scraper element for removing material is arranged on the end region of the end of the grinding roller that is provided with an edge element.
- the scraper element is used in particular for at least partially removing material that has accumulated on the end region of the grinding roller.
- the material is scraped off by the scraper element during operation of the roller mill, with the grinding rollers rotating in opposite directions.
- the scraper element is preferably arranged on the end area of the grinding roller in such a way that it does not touch the grinding roller.
- the end area of the grinding roller comprises, for example, the end face of the grinding roller, the surface of the grinding roller adjoining it, and an area surrounding the surface of the grinding roller, in which material is deposited.
- such a region has a height of more than or equal to 1.5mm-3mm, in particular more than or equal to 2mm-5mm, preferably 4mm.
- the edge element includes, in particular, an encircling circular ring, preferably a circular disk.
- the edge element is attached to the end face of the respective grinding roller, for example screwed or welded.
- an end gap is preferably formed in each case.
- a gap at the end prevents the edge element from colliding with the end region of the respectively opposite grinding roller in the event of the grinding rollers running out of alignment, with the grinding rollers lying opposite one another not being arranged parallel to one another.
- the grinding rollers include, in particular, a roller base body, with the edge element being detachably connected to the roller base body of the respective grinding roller.
- the grinding roller preferably comprises a drive shaft for driving the grinding roller, on which the roller base body is arranged.
- a detachable arrangement of the edge elements on the roller body offers the advantage of quick and easy replacement of the edge elements in the event of wear.
- the edge elements are, for example, glued, soldered, welded or screwed onto the roller body and preferably have wear protection.
- the wear protection is arranged on the inner surface of the edge element pointing in the direction of the milling gap.
- Such wear protection includes, for example, a wear-resistant coating, such as build-up welding, wear-protection elements or wear-protection coatings.
- the edge elements are preferably made of steel.
- this wear protection layer is thicker on the end areas of the roll ends, which are provided with edge elements, than on the other areas of the grinding rolls. This leads to increased grinding pressure, which puts more stress on the edge elements and causes them to wear out or fail more often.
- the material build-up on the edge elements at the ends of the grinding rollers is reliably prevented by means of the scraper elements. This minimizes the risk of increased wear and failure of the edge elements.
- the scraper element is arranged in such a way that it removes material that has accumulated on the edge element and/or on the end region of the grinding roller during operation of the roller mill.
- the scraper element is arranged to be stationary or movable relative to the rotatable grinding rollers, so that the grinding rollers rotate relative to the scraper element.
- the scraper element is arranged at a distance from the edge element and/or the end region of the grinding roller.
- the distance between the scraper element and the edge element and/or the end area of the grinding roller is preferably more than or equal to 1.5 mm-3 mm, in particular more than or equal to 2 mm.
- a distance between the scraper element and the edge element and/or the end area of the grinding roller prevents the scraper element from coming into contact with the grinding roller and thus reduces wear on the scraper element.
- the scraper element is arranged in such a way that the distance between the scraper element and the edge element and/or between the scraper element and the end region of the grinding roller can be adjusted.
- the thickness of the material layer at the end areas of the grinding rollers should not exceed a specific value of, for example, 1-30 mm, in particular 2-25 mm, preferably 5-10 mm.
- An adjustable distance ensures that when the scraper element wears, the distance between the scraper element and the edge element and/or the end area of the grinding roller is kept constant.
- the service life of the wiper element is extended and replacement is not necessary in the event of wear.
- the roller mill has a stationary machine frame and the scraper element is attached to the machine frame.
- the machine frame includes, for example, a number of frame elements that are connected to bearing blocks of the grinding rollers, so that the grinding force acting on the grinding rollers is transmitted to the machine frame.
- a machine frame of a roller mill comprises a frame element which extends essentially in the axial direction of the grinding rollers and to which the scraper element is preferably attached. The scraper element extends from the machine frame in the direction of the grinding roller, in particular in the end area of the grinding roller.
- the roller mill has at least two stripper elements, which are arranged at end regions of different roller ends of the grinding roller.
- the stripper elements are preferably arranged on opposite end areas of a grinding roller.
- the scraper element has a scraper plate which is formed from a wear-resistant material such as tungsten carbide.
- the stripper plate is arranged on the end of the stripper element facing the grinding roller and is in contact with the material to be stripped during operation of the roller mill. The stripper plate is therefore exposed to a high level of wear, with wear-resistant material extending the service life of the stripper plate.
- the wiper element has an arm on which the wiper plate is detachably fastened.
- the stripper plate is clamped or screwed to the arm.
- the stripper plate preferably protrudes beyond the arm in the direction of the grinding roller.
- each of the grinding rollers has an edge element at an end region of a roller end, which is designed such that it extends across the grinding gap and at least partially covers the opposite grinding roller at the front.
- the edge elements are arranged diagonally opposite with respect to the end regions of the grinding rollers.
- the wiper element extends along an edge element.
- the wiper element extends in the radial direction Grinding roller, for example parallel or oblique to the edge element.
- the distance between the edge element and the wiping element is preferably constant over the length of the wiping element.
- the invention also relates to a method for operating a roller mill for comminuting granular material with a first grinding roller and a second grinding roller which are arranged opposite one another and can be driven in opposite directions, with a grinding gap being formed between the grinding rollers.
- At least one of the grinding rollers has an edge element on an end region of a roller end, which is designed in such a way that it extends across the grinding gap and at least partially covers the opposite grinding roller at the front.
- the method has at least the following step: removing material from an end area of a grinding roller. The material is preferably removed from the roller mill during operation of the roller mill with the grinding rollers rotating.
- the material is removed by means of two scraper elements which are stationary relative to the grinding rollers.
