Abstract: The present invention relates to conveyors, comprising at least one circulating conveyor strand (7, 8), wherein the conveyor strand has at least one clamping connection (1), wherein at least one sensor (2) is arranged in the clamping connection (1), a transmitter (3) for wirelessly transmitting data is arranged on the conveyor strand (7, 8), the sensor (2) is connected with the transmitter (3), and a receiver (4) for receiving the data transmitted by the transmitter (3) is provided.

Abstract: The present invention relates to a device for treatment of a material mixture consisting of substitute fuel and impurities, having a vertically aligned central feeder (1), a separating unit (2) arranged underneath the central feeder (1), a rotor mill (3), wherein the rotor mill (3) is arranged above the separating unit (2) and surrounds the central feeder (1), a flow device (4) for generating an upwardly directed gas flow, wherein the rotor mill (3) has a multistage design, and a respective separating device (6) is arranged between the stages (5.1, 5.2) of the rotor mill (3), wherein material mixture not held back by the separating device (6) is further comminuted in the following stage (5.2).

Abstract: The invention relates to a belt bucket elevator for conveying bulk material, comprising a driven endless belt (23), which is circulated via drums arranged on a bucket elevator head and on a bucket elevator base, and comprising at least one row of buckets (10), each of which is individually fixed to the belt (23) and has a base (15), a back wall (11), lateral walls (13), and a front wall (12), said row extending in the running direction of the belt (23), characterized in that each of the buckets (10), which are arranged in close succession relative to one another, in at least one row extending in the running direction of the belt (23) has a smaller width at the base (15) than at the upper ends of the lateral walls (13), which thus extend outwards laterally and in that the arrangement of the buckets on the belt (23) is designed such that the belt (23) including the outer lateral edges of the belt, is completely covered by the buckets (10) arranged thereon.

Abstract: A chain, in particular a technical chain, preferably a unidimensionally movable chain (plate link chain), more preferably a bolt chain or roller chain, has at least one or more chain links. The at least one chain link is constructed with pretensioning. A manufacturing method includes the following steps: assembling at least one chain link from at least two link plates with link plate holes and two bolts or sleeves. In the non-assembled state, the link plate is not straight, in particular has a curved form, and/or the link plate and the link plate holes have a hole axis, wherein the hole axis is not right-angled, and/or, in the non-assembled state, the bolt or the sleeve is not straight, in particular has a curved form. The chain is assembled from at least two chain links and at least one chain link is manufactured in this way.
