A plant for shredding metal waste, comprising at least one working chamber, means for shredding metal waste and motor means operatively connected to the shredding means. The plant further comprising sensor means operatively associated with the motor means and/or shredding means for monitoring at predetermined time intervals at least one working parameter connected to the wear thereof, and at least one data processing unit operatively connected to the sensor means. The data processing unit including: data storage means for storing for a predetermined period of time the values of said at least one working parameter detected by said sensor means and an an artificial intelligence software program so as to allow the plant manager to plan the maintenance of the motor means and/or shredding means.

A tree stump grinding wheel assembly includes a rotor having a plurality of holders distributed about its cutting periphery. Each holder has a neck in which resides a socket adapted to receive the shank of an indexable tooth. A head is attached to one end of the shank and screw threads are formed in its other end. The head has a plurality of flats configured to sequentially register with a forward shoulder on the neck. A hermetic spring is operatively disposed on the shank between a rearward face of the socket and a retention nut. The hermetic spring is made of elastomeric material and has a tapered nose that self-seats in a countersink at the rearward opening of the socket. The hermetic spring has an accordion-like bellows section. The bellows section can have a central annular bulge.

Disclosed is a pruning and sieving apparatus, which resolves time-consuming and laborious problems in the existing pruning method of flower plants. The pruning and sieving apparatus includes a hollow body, including two relatively disposed open axial ends; an interior pruning lining attached inside the hollow body, where the interior pruning lining includes a plurality of sidewall pruning holes arranged in a distributed manner; a sieving screen, where the sieving screen includes a plurality of sieving holes arranged in a distributed manner, and is disposed in the interior pruning lining to divide the internal space of the interior pruning lining into a pruning chamber and a collection chamber; and two end caps disposed on the two open axial ends.

A food recycler can include a case having a case volume between 8.79 liters and 35 liters, a control system, a user interface in electrical communication with the control system, and a bucket being configured with a bucket volume, wherein a ratio of the bucket volume to the case volume is between 0.0717 and 0.2857. The recycler can include a motor in communication with the control system, the motor being configured adjacent at least in part to the bucket, a gearbox configured below the bucket and in mechanical communication with the motor, a filter system having at least one filter and configured to receive air from a top portion of the bucket and a drying component configured to remove water from waste food items.

A food recycler includes a case, a control system within the case, and a set of user interface components that are usable to at least cause the control system to initiate a food recycling cycle. The food recycler also includes a motor within the case and a bucket that has a volumetric capacity between 2.51 and 10 liters. A filter system configured to accommodate air filters is also included in the case of the food recycler. To remove water from waste food items, the food recycler includes a drying component.

In one embodiment there is provided a system and device for composting food waste and non-food waste compostable biopolymer materials together to create a compost.

A system and method for tennis ball recycling that processes tennis balls into one or more constituent components to generate useful products is disclosed. The system includes a hopper to hold the balls for recycling; a grinder having a plurality of blades to initially cut the tennis balls in a first step to separate the rubber from the nylon; a cyclonic extractor that further separates loose fibers out in a second step; a trommel separator that further filters the broken down components of the tennis balls for use in new products.

A foliage shredder that can shred inputted foliage matter into uniform sized particles without pulverizing the inputted foliage matter includes a housing, a shredding axle, a motor, a stand, a digital timer, a power cord, and a lid. The shredding axle is concentrically positioned within a cylindrical compartment of the housing and rotatably coupled to a rotor of the motor. A stator of the motor is externally connected to the housing and electrically connected to the power cord through the digital timer. The lid is terminally attached to the housing thus closing the cylindrical compartment. The cylindrical compartment functions as a container unit for the inputted foliage as the electrically powered shredding axle shreds the inputted foliage into uniform sized particles.
