The present disclosure encompasses a composition comprising three-dimensional shapes, wherein each shape consists essentially of choline chloride, and methods of making such three-dimensional shapes.

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.

A waste shredding device including at least one shredding shaft; an internal combustion engine; a first and a second powertrain between the internal combustion engine and the shredding shaft; at least one energy converter coupled to the internal combustion engine in the first powertrain for converting mechanical energy of the internal combustion engine into storable energy; and at least one auxiliary motor supplied with the storable energy in the first powertrain for introducing mechanical energy into the first powertrain. The waste shredding device additionally includes an energy store for storing at least part of the storable energy in the event of periods with low power demand and for at least partially supplying the at least one auxiliary motor with the storable energy in the event of periods of high power demand.

The invention relates to a drive system for driving a crusher of a material crusher plant having a main drive and a power transfer unit driven by the main drive, wherein the power transfer unit drives at least one generator and a first hydraulic pump which is connected to the power transfer unit in a shiftable manner. It is provided that a shiftable fluid coupling is installed in the transmission path from the power transfer unit to the crusher, that the shiftable fluid coupling and a pump are interconnected in a fluid conveying manner in a pump circuit and that a fluid can be supplied to the shiftable fluid coupling by means of the pump.

The invention further relates to a method for operating such a crusher.

The drive system permits a gentle operation of the crusher at a small number of required components.

The invention relates to a test arrangement for testing breakage and mechanical properties of rock particles. Test arrangement comprises: a support (1, 2); two counter-rotatable crushing wheels (3, 3′) supported on the sup-port (1, 2); and a drive arrangement (M1, M2) for rotating the crushing wheels (3, 3′), said crushing wheels (3, 3′) facing each other and defining therebetween an in-put gap (G) for the rock particles, said wheels being arranged to break the rock particles (RP) to smaller daughter particles (DP), wherein the test arrangement is arranged to receive only one rock particle at a time to be inputted to the input gap for breakage testing, an energy measurement arrangement (5, 5′) arranged to measure in-formation relating to energy absorbed by the rock particles (RP) during the breakage, a processor (PR) coupled to the energy measurement arrangement and arranged to receive, as inputs, at least one degree of breakage of the rock particles as a result of the breakage and the corresponding breakage energies absorbed by the rock particles (RP) during the breakage, to determine a correlation between the degree of breakage and the breakage energies, and to output the correlation.

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.

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.
