A measuring device for ascertaining the temperature of a roller surface of a roller body is insertable into a recess of the roller body and includes at least first and second temperature sensors, a mounting rod on which the sensors are situated in the axial direction of the mounting rod spaced apart from each another, and, on each side of each respective one of the temperature sensor in the axial direction a respective supporting element arranged on the mounting rod. Between the supporting elements, the mounting rod is flexible such that each of the temperature sensors is able to be pressed onto an inner wall of the recess with a defined contact force.

The present invention relates to a roll film shredding device, and more specifically to a roll film shredding device which rapidly and effectively shreds a long object rolled up into a roll shape, and in particular twists and crumples an object and then performs a shredding operation, thereby effectively shredding an object even though the object is thin, flexible and viscid. The roll film shredding device according to the present invention includes a support frame; an object-to-be-shredded introducing member coupled to the support frame; an object-to-be-shredded twisting unit rotatably installed to the object-to-be-shredded introducing member and performing a twisting operation for an object to be shredded; a rotary driver driving the object-to-be-shredded twisting unit to rotate and perform the twisting operation; and a cutter cutting the object twisted by the object-to-be-shredded twisting unit.

A gyratory roller crusher in which the rollers have a corrugated profile and at least one of the rollers is eccentrically mounted to give a relative gyratory motion to the rollers resulting in additional breakage mechanisms for the comminution of a very wide range of feed material, vastly improved crushing ratios and increased throughput compared with conventional roller crushers.

The present invention relates to a grinder roller for use in a grinder roller pair, in particular a grain roller pair, comprising at least one sensor for the detection of measured values which characterize a state of the grinder roller, wherein the sensor is arranged in a receiving opening of the grinder roller, at least one data transmitter for the contactless transmission of the measured values of the at least one sensor to a data receiver, wherein the sensor is enclosed in the receiving opening by means of a cap made from ceramic material. Furthermore, the present invention relates to a corresponding grinder roller pair, to a production plant which comprises a grinder roller pair of this type, to a corresponding cap, to a kit consisting of a corresponding cap and a fastening device, and to a method for operating a product processing plant of this type.

A milling roll of a roll mill may have a roll main body and an edge element that is attached to an end region of a roll end of the milling roll and extends in a radial direction beyond a surface of the roll main body. The edge element comprises a base flange and a spacer element that is attached thereto. Wear protection elements can be attached to the spacer element. Furthermore, a roll mill may have a first milling roll and a second milling roll that are arranged opposite one another and can be driven in opposite directions. A milling gap is disposed between the milling rolls, and an edge element on one of the milling rolls may extend over the milling gap and at least partially cover an end side of the opposite milling roll.

An infeed protection device for a rolling mill, comprising a housing and a plurality of parallel rotating rollers. A product infeed is formed by two of the rollers which rotate about rotational axes arranged parallel with one another and arranged at an adjustable roller space with respect to one another. The infeed protection device comprises a profile which is arranged parallel with the rollers forming the product infeed and extends over the length of the product infeed. In an infeed direction of the rotating rollers, the profile is upstream of the rollers forming the product infeed. At least one vertical through-opening is formed in the profile. A space is formed between the profile and the rollers. The infeed protection device further comprises a holder for fastening the infeed protection device to the housing of the rolling mill.

Roller packages (IO) for grinding devices (70), comprising a first roll (11), which is maintained by at least one first bearing body (13), and a second roll (12), which is maintained by at least one second bearing body (14). The first bearing body (13) and the second bearing body (14) are prestressed against each other and comprise stop elements (17,19) with stop surfaces (18, 20), the contact of which counteracts a contact of the rolls (11, 12). The rotational position of the first stop element (17) determines the minimum width of the grinding gap. Also disclosed are grinding devices (70), methods for operating a roll assembly (10) and methods for determining the radial force acting between the rolls (11, 12) of a roll assembly (10).

A carrying device (1) for the frontal removal of a roll body from a roll frame, comprising a main frame (2) and a receiving section (3) for the roll body. The receiving section (3) can be transferred from an introduction position (E) into a supporting position (S). The receiving section (3) has a profile which at least partially encloses the roll body in the supporting position (S), and the carrying device (1) can be pushed in below the roll body with the receiving section (3) in the introduction position (E), and the roll body is carried with the receiving section (3) in the supporting position (S).
