Process for manufacturing a blow-in insulation material made of straw, including a processing step in which the straw is crushed between rolls in a crushing apparatus, a crushing nip in the crushing apparatus being selected in such a way that the straw nodes are crushed during the crushing operation.

System and method for controlling the startup sequence of a roller crusher is disclosed. The roller crusher includes two generally parallel rollers that are separated by a gap where the rollers rotate in an opposite direction. During startup, the gap between the rollers is greater than the gap during normal production and a feeding arrangement is run at a speed that is lower than a normal production feed rate. The rollers are rotated at a predetermined speed that is less than the speed during normal production. Other parameters of the system are set such that material is fed over the entire length of the rollers and the no crushing force is exerted during the startup. The method and system of the present disclosure reduces the amount of stress on the rolls, frame and hydraulic system of the roller crusher.

Roller pairs for processing a product, containing two grinding rollers, wherein at least one roller contains at least one sensor for obtaining measured values that characterize a state of at least one of the rollers, in particular a state of a circumferential surface. The sensor has a data connection to a data transmitter designed to transmit the measured values to a data receiver in an contact-free manner. Additionally, a measuring device for insertion into a receiving opening of a roller body of a roller of a roller pair, a product-processing installation, in particular a grinding installation containing at least one roller pair, a method of operating a product-processing installation, and a method of converting and/or upgrading at least one roller body are disclosed.

An example method for operating a plant, which has at least one assembly with a rotating surface that wears to an increasing extent during the operation of the plant, may involve evaluating a wear state of the rotating surface of the assembly. Based on the wear state of the rotating surface, a manner in which the plant is operated may be modified to prolong the running time of the assembly until, for instance, a next-scheduled service or maintenance interval. The modified manner of operating the plant may be adapted to the wear state of the rotating surface. Several examples of such modifications include changing a quantity of water sprayed onto material to be comminuted, changing a quantity of grinding additive added to material to be comminuted, and/or changing a contact pressure of a grinding roll of the assembly.
