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.

A control method of a treatment plant for elements to be recycled or disposed of, having a crushing roll to reduce the size of the elements to be recycled or disposed of, and a screen operatively arranged upstream of the crushing roll to enable passage therethrough only of elements having a size larger than a predetermined size, includes the steps of measuring the current absorbed by the crushing roll; comparing the measured current value to a first predetermined value; and reducing the vibrations of the screen, if the measured current exceeds the first predetermined value.

The exemplary embodiments herein provide a roller grain mill assembly having a lower frame, a plurality of roller grain mills attached to the lower frame, an upper frame extending upwardly from the lower frame, a single electric drive mechanically coupled to each of the roller grain mills, and a cyclone separator placed in gaseous communication with the roller grain mills and located above the electric drive. In some embodiments, a centrifugal scatterer may be suspended from the upper frame and placed in gaseous communication with the roller grain mill. In other embodiments, a cyclone separator may be placed in gaseous communication with the roller grain mill and centrifugal scatterer. An electric drive coupled to each roller grain mill may be cantilevered off the lower frame.

A debucking machine, for use with processing industrial hemp or cannabis, is provided. Embodiments of the debucking machine include counter-rotating rollers equipped with rubberized combs for gently removing flowers, or buds, from harvested industrial hemp or cannabis. Embodiments of the debucking machine are portable and may be moved from location to location within a drying shed.

A high-pressure roller mill for comminuting brittle grinding stock having at least two adjacent rotating grinding rollers which rotate in opposite directions and form a nip therebetween, wherein a first grinding roller is a fixed roller and a second grinding roller is an idle roller, and a lateral wall at each of the two ends of the nip. Each lateral wall has a vibration device which sets the lateral wall into mechanical vibration.

The mobile waste comminuting device of the invention comprises: at least one comminuting shaft; an internal combustion engine; at least one generator that is coupled to the internal combustion engine to convert mechanical energy supplied by the internal combustion engine into electric energy; at least one electric motor which is powered by the electric energy so as to drive the at least one comminuting shaft and change the direction of rotation thereof; and an energy store for storing energy and at least partly powering the at least one electric motor with electric energy, in particular for storing energy during periods of low power demand and supplying energy during periods of high power demand in relation to the nominal power of the at least one generator.

A system for grinding particles may include a roller mill apparatus with a pair of mill rolls, a motor assembly for rotating the mill rolls, and a controller assembly for controlling aspects of operation of the roller mill apparatus. The controller assembly may include a size detection sensor for detecting a particle size of material moving through the apparatus, and processing circuitry comparing a current particle size value with a target particle size value. The processing circuitry may execute instructions to compare the current particle size value to the target particle size value, and adjust a magnitude of a differential in rotational speeds of the mill rolls based upon the comparison of the current particle size value to the target particle size value to cause a future particle size value to move closer to the target particle size value.
