Patent number: 11679941Abstract: A vibratory conveyor system includes a product transfer pan linked to a shaker base via spring arms. Vibration transferred from the shaker base to the spring arms causes the product transfer pan to oscillate and convey products across the product transfer pan. The product transfer pan has apertures defined therein, such that excess coatings on (or fallen from) the conveyed products tend to fall through the apertures. A chute situated beneath the apertures collects the fallen coatings, and preferably diverts it to a side of the conveyor for collection and subsequent reuse or disposal. The chute is preferably linked to the product transfer pan such that the chute and pan oscillate in tandem.Type: GrantFiled: September 20, 2021Date of Patent: June 20, 2023Assignee: Vibratorv Solutions.

The apparatus includes an inclined particle separating screen secured in a mount frame and characterized by multiple steps disposed perpendicular to the path of material flow. The mount frame is suspended in a support frame by resilient float mounts and vibrated by a vibratory motor mounted on the mount frame. The particulate material is loaded on the top inclined end of the vibrating screen and as the material cascades down the steps of the screen, particles smaller than a selected size fall through one of multiple, adjacent openings provided in each step and are collected or discharged for further processing in a stream below the screen, whereas larger particles are collected or discharged in a separate stream at the foot of the screen.Type: GrantFiled: June 20, 1996Date of Patent: May 18, 1999Assignee: Tinsley, Inc.Inventors: Travis M. Tinsley, Douglas M. Tinsley, Gary G. Gathright, Christofer B. Blank, Justin R. Price, Lorina J. White, Philip E. Begley

Patent number: 5749471Abstract: A vibrating screen for the sizing of granular material such as gravel, sand, crushed stone, etc., having a frame (1) and a screen body (2) supported on springs (6), directional oscillating movements being imparted to the screen body by a motor powered vibrator mechanism (3). The screen has two or more screen decks (11-13), each one divided into three component screens (14a-c, 15a-c, 16a-c) having successively decreasing inclinations in a direction towards the discharge end (9) of the screen, each lower screen deck furthermore having an increased inclination in relation to the nearest deck above.Type: GrantFiled: November 7, 1995Date of Patent: May 12, 1998Assignee: Svedala-Arbra ABInventor: Anders Andersson

Patent number: 5735409Abstract: Detachable screen cloths (14) are fixed on a screen cloth element (11) having a rigid support frame (12, 13) serving as a holder and intended to be fixed in the screen frame (10) of a screening machine. The detachable screen cloths (14) have a rigid screen cloth frame (30, 31) surrounded at least partially by elastomeric material. The rigid mounting frame (12, 13) of the screen cloth element has a guide device (32, 33) which is laterally open for receiving and holding the screen cloth (14). The screen cloth (14) is in sliding engagement with the guide device (32, 33) during the insertion thereof into the guide device. The screen cloth (14) and the guide device (32, 33) have inter engaging surfaces preventing, during the screening operation, relative movements between the screen cloth (14) and the rigid mounting frame (12, 13) of the screen cloth element in directions making an angle with the plane of the screen cloth.Type: GrantFiled: March 27, 1995Date of Patent: April 7, 1998Assignee: Trellex ABInventor: Mats Anders Malmberg

Patent number: 5641070Abstract: A shale shaker has been developed which, in one aspect, has one or more upper screens and one or more lower screens with an upper screen at a discharge end of the shale shaker and a lower screen disposed to receive material discharged from a discharge end of one of the upper screens. In one aspect a portion of a lower screen underlies the discharge end of the upper screen. In another aspect a solid flowback pan prevents material falling through the upper screen(s) from falling onto the lower screen(s); and, in another aspect, the pan prevents material on a top of the lower screen(s) from falling into a bottom sump of the shale shaker which receives material which has fallen through the screen(s).Type: GrantFiled: April 26, 1995Date of Patent: June 24, 1997Assignee: Environmental Procedures, Inc.Inventor: Kenneth W. Seyffert

Patent number: 5398815Abstract: A waste material separating apparatus and method of separating waste landfill material which apparatus and method includes a frame and a vibratory screening deck or tier within the frame, the screening deck having a plurality of generally parallel, straight rod elements to act as bludgeons on the waste material. The rod elements are removably extended from a transverse rail. Waste material to be separated into a coarse material and a finer material is discharged onto the rod element. The separating apparatus has an eccentric rotating shaft secured to the deck to impart vibratory motion to the rod elements so that the free ends of the vibratory fingers vibrate in a generally vertical direction, and bludgeon and break up the compacted solid waste landfill material.Type: GrantFiled: March 31, 1994Date of Patent: March 21, 1995Assignee: The Read CorporationInventor: Robert J. Hadden

Patent number: 5337901Abstract: An apparatus and process for screening a product grade of particulate matter from a feed-stream of particulate matter is provided. Specifically, the apparatus is a vibration screening action machine which vibrates, including motion having a component thereof perpendicular to the plane of the screen deck, at least one screen deck having a mesh defining the lower limit of the product grade. Such vibration screening action machine is optimized for ensuring the throughput of particulate fines through the mesh defining the lower limit of the product grade and thus substantially removing particulate fines from the product grade by setting the screen deck at a relatively low angle, as measured from horizontal, of less than 15 degrees.Type: GrantFiled: February 14, 1992Date of Patent: August 16, 1994Assignee: Minnesota Mining and Manufacturing CompanyInventor: Dean A.

The separating apparatus has an eccentric rotating shaft secured to the deck to impart vibratory motion to the rod elements so that the free ends of the vibratory fingers vibrate in a generally vertical direction, and bludgeon and break up the compacted solid waste landfill material. The solid material is progressively moved from the tall to short end of the frame by forward rotary motion of the rotary shaft and falls off the ends of the vibratory rod elements onto the lower tiers to decompact and break up and tumble the waste material.Type: GrantFiled: October 8, 1992Date of Patent: June 21, 1994Assignee: The Read CorporationInventor: Robert J.
