Subject-matter of the invention is a screen plate for a separating device for classifying bulk material. The screen plate comprises a profile region having a profile having depressions and elevations extending in a direction of a takeoff side, the profile being describable by a circle arc of a first circle K1 and a circle arc of a second circle K2, and the circles K1 and K2 being disposed adjacent to one another, with the circle arc of the first circle K1 with a radius r1 describing elevations and the circle arc of the second circle K2 with a radius r2 describing the depressions. Each depression undergoes transition, in a takeoff region, into an opening which expands in the direction of the takeoff side, the opening having an opening edge with a width corresponding to the length of the radius r2 to 2*r2.

A method is described for recycling the infill of a synthetic turf, said infill being formed by a plurality of different granular materials, including at least sand granules, polymeric material granules and synthetic grass filaments, said method comprising the following steps: drying the infill, screening the infill through a plurality of successive screens (130,140,180, 185) each having passage holes of different sizes subdividing the infill into a plurality of groups of granular material having different size ranges, separating each group of granular material into two subgroups of granular material based on the difference in density of the materials, and conveying the separated subgroups of granular materials to different collection containers.

The present invention provides a combination screening apparatus for screening a mixed material into three graded streams, comprising a disc screen wholly, substantially or partly located within a rotary drum screen. The present invention may be conveniently arranged on a mobile chassis with a simple arrangement of a feed hopper to feed a feed end, and a layered or stacked configuration for the discharge of the so-formed graded streams at a discharge end.

Tables for sorting agricultural producta. The tables include legs, a deck, and a vibration generator. The deck is supported on the legs. The deck includes a loading end, a terminal end, and a grate. The terminal end is opposite the loading end. The grate extends between the loading end and the terminal end and defines the grate openings. The vibration generator is mounted to the deck and configured to vibrate the deck. The grate supports agricultural products that are larger than the grate openings. Agricultural products that are smaller than the grate openings pass through the grate. The vibration generator vibrating the deck causes the agricultural products to move across the deck over the grate.

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.
