Disclosed embodiments include methods and systems for autonomous data collection and system control of a material recovery or recycling facility. In some embodiments, a central control system receives inputs in the form of at least one data stream from each of one or more environmental sensors that reflect the status of a material recovery facility (MRF). The inputs are used to determine the operating status of one or more components of the MRF, and/or composition of a waste stream being processed by the MRF. At least one material handling unit is controlled in response to the inputs to optimize the recovery and/or purity of recyclable or recoverable materials from the waste stream. A service unit or mechanism may also be controlled in response to the inputs indicating that a component of the MRF requires servicing.

A method for cleaning of a roller screen transporting and screening particles by means of at least three rotating rollers. The rollers are installed in succession at given clearances and arranged transversally in relation to the transport direction of the particles to screen a desired range of particle sizes. At least one roller changes its circumferential velocity and/or its rotational direction over time at defined time intervals for defined time periods such that for this defined time period for at least one pair of neighbored rollers one roller has a higher circumferential velocity than the other and/or both rollers roll in opposite rotational directions.

A system for processing usable crop intermixed with debris and having a frame with a conveying system thereon. The conveying system has a first debris separating assembly with a first subframe having a plurality of cooperating rollers that are configured to cause separation of debris from the usable crop. A second debris separating assembly, different than the first debris separating assembly, has a second subframe with a plurality of cooperating rollers thereon that are configured to cause separation of debris from the usable crop. The frame and first and second debris separating assemblies are configured as overall like modules so that the first and second debris separating assemblies can be separately operatively connected, one in place of the other, on the frame.

A fruit sorting table includes: a conveyor for conveying a fruit crop along a conveying plane, between an intake area and a discharge area, a screen extending in the conveying plane between the intake area and the discharge area, the screen having openings for sorted fruit to pass through from the conveying plane to an area for receiving sorted fruit situated under the conveying plane. The sorting table has at least one device for measuring one of a quantity of fruit and a flow rate of fruit passing through the screen over at least one reference section of the screen, the reference section being situated between the fruit intake area and the discharge area, and set apart from the fruit intake area, a device for adjusting the sorting table in response to the measurement device. Application, in particular, to sorting a grape crop.

A roller assembly for a screening device includes a shaft extending along a width direction, a pair of discs disposed on the shaft, and a spacing assembly disposed on the shaft between the pair of discs. The spacing assembly includes an inner spacer disposed around the shaft and an outer spacer disposed around the inner spacer. The outer spacer has a body defining an inner receiving space and a support element disposed in the inner receiving space. The body abuts against the discs and is formed of an elastically compressible material. The support element limits compression of the body along the width direction.
