Abstract:
The sieve device is used as a feeder and separator of materials which are difficult to separate such as household refuse, industrial waste, cumbersome or dry waste. In order to achieve an optimun distribution and cleaning effect, there are provided two superposed screen sieves (12, 13) comprised of overlapping bars having a conical cross-section and which are free at their ends. The cleaning effect of the device is improved by the step offset of the sieves (12, 13) and by the circulation effect resulting therefrom. The oscillation motion is obtained by means of oscillating elements made of rubber and by an uneccentric drive.

Abstract:
Invention refers to quality control system for detection and identification of insects, pests and the like in such product like cereals, seed, grains and the like. The Quality control system comprises a sample collecting device (1) for collecting a sample in pre-determined amount from a product (P) to be tested, a self-cleaning cyclone filter (2) for cleaning the sample, a vibro separator (3) for separation of the sample in pre-determined sizes or grades, a heating chamber (4) for heating the sample separated in the vibro separator. The system further comprises an identification device (5) for detection and identification of live insects, pests and the like in said sample.
Abstract:
A vibrating screen feed conveying apparatus for conveying and separating sticky “moisture laden bulk solids” which are sticky and wet flowing onto a vibrating screening feeder and into a hopper. The apparatus includes a bed on which material is conveyed, a longitudinal counterbalance supported on a plurality of isolation springs, a plurality of inclined drive springs extending between the bed and the longitudinal counterbalance, and a plurality of stabilizers for controlling movement of the drive springs along their central axes. A plurality of vibratory motors, each having rotatable eccentric weights are attached to the rear end of the longitudinal counterbalance. The eccentric weights rotate in phase with one another to vibrate the bed at a vibration frequency.
Abstract:
An apparatus includes a vibratory separator having a frame and a screen, a lift housing disposed proximate the vibratory separator, and a lift system disposed in the lift housing and configured to selectively engage a portion of the vibratory separator to lift the portion of the vibratory separator. A method includes actuating an actuator and vertically extending a lifting member, contacting an alignment device coupled to the lifting member with a corresponding alignment device coupled to a portion of a vibratory separator, and raising the portion of the vibratory separator to provide access to a screen of the vibratory separator.
Abstract:
Problem A sieving apparatus enabling separation based on the difference in cross-sectional diameter and separation based on the difference in aspect ratio is provided. Solution A sieving apparatus 1 includes a first sieving portion including a sieve provided with a plurality of elongated holes or slits and a second sieving portion used after sieving in the first sieving portion and provided with a sieve constituted by a porous plate. A hole diameter of the porous plate constituting the sieve included in the second sieving portion is longer than an opening width of the elongated hole or the slit of the sieve included in the first sieving portion. The sieve included in the first sieving portion is constituted by a wedge wire screen. The sieve included in the second sieving portion is constituted by a punching metal mesh having approximately circular holes.
Abstract:
A screening apparatus (1) is disclosed.The screening apparatus (1) comprises a support (2); at least two screen decks (30) arranged one over the other as an assembly (3), each screen deck (30) including a screen frame (31), a screen (32) and a chamber underlaying the screen surface, an outlet duct (12) for oversized material and an outlet duct (13) for undersized material that is in communication with the chamber; mountings (4a, 4b) configured for mounting the assembly (3) of the at least two screen decks (30) to the support (2); and a feed unit (7) configured to feed the material to be screened to each screen deck (30); wherein the feed unit (7) is arranged on the support (2) and configured to be moved between a feed position and a maintenance position.
Abstract:
Beim Trocknen von organischen Festbrennstoffen, insbesondere von Waldhackschnitzeln, mittels Trocknung des Festbrennstoffs in einer Trocknungs-vorrichtung ( 4 ) mittels eingeblasener Trocknungsluft, wobei der Festbrennstoff während der Trocknung umgewälzt wird, sodass die Trocknungsluft den Festbrennstoff durch-strömt, wird erfindungsgemäß dabei die Zufuhrmenge an Festbrennstoff pro Zeiteinheit so geregelt, dass entweder die Abluft eine bestimmte Abluft-Ziel aufweist oder der aus der Trocknungsvorrichtung ( 4 ) austretende Festbrennstoff eine Restfeuchte von 13-15 % aufweist.
