Systems and methods associated with screening systems are provided. In one example implementation, a screening system has a plurality of screen panels. Each of the screen panels define a screening surface with one or more apertures configured to separate material. The system includes a panel node associated with each of the plurality of screen panels. The system includes a controller node associated with the screening system. The controller node is operable to communicate with each panel node. Each panel node can include one or more sensing elements. The panel node further comprises a communication circuit configured to wirelessly communicate information to the controller node.

An aggregate production method includes procuring stone waste by-products, sorting the stone waste by-products by type and color, and subjecting the sorted stone waste by-products to a two-stage crushing process to produce aggregate. The aggregate is screened into different sizes and placed according to size into a bag or container.

A system for segregating a mixture of oxidizable catalyst material and inert support media. The system comprises an enclosure configured to contain inert gas. The enclosure includes a plurality of stacked screens disposed therein. The stacked screens include openings that decrease in size from a top of the stack to a bottom of the stack. The enclosure also includes an inlet to deliver the mixture to an uppermost stacked screen and outlets to direct the separated support media and catalyst material to a location outside the enclosure.

Example implementations provide a control system to control a system for actuating a sieve, the system comprising an actuator mechanism to actuate the sieve to produce a sieving action to sieve a particulate within the sieve, and a sensor to determine an electrical characteristic associated with the actuator mechanism; the controller comprising circuitry to determine the amount of the particulate within the sieve in response to the determined electrical characteristic associated with the actuator mechanism.

A screening apparatus includes a vibrating screen assembly that includes a screen and a vibrating mechanism operable on the screen to cause vibration of the screen, the screen having a feed end and a discharge end. At least one shield member is positioned on the screen and is configured to cover part of the screen between the feed end of the screen and a position intermediate the feed and discharge ends of the screen, such that particulate material for screening by the screen can be fed on to the, or each, shield member, the, or each shield member being positioned on the screen so that a vibrational pattern of the screen is imparted to the shield member. An adjustment mechanism is operatively engaged with the, or each, shield member to adjust a position of a discharge end of the, or each, shield member relative to the discharge end of the screen.

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.
