| 20090230029 | SCREENING MACHINE AND ASSOCIATED SCREEN PANEL - A screening machine of the type used to separate or classify mixtures of solid particles of different sizes includes a machine frame and a perforate screen panel mounted for movement relative to the machine frame during a screening operation. The screen panels are pre-tensioned mesh screen material mounted in a peripheral rim for separating various granular and particulate materials. The screen panel is slid into the side of the machine frame in a direction orthogonal to the direction particulate matter moves when the screening machine is operating. The screen panel peripheral rim has a shaped or other cross section adapted to hold a large seal member that provides a positive sealing surface for contact with the machine frame to prevent particulate matter from escaping off of the screen panel during use. | 09-17-2009 |
| 20110036759 | Screening machine and associated screen panel - A screening machine of the type used to separate or classify mixtures of solid particles of different sizes includes a fixed base and a perforate screen mounted for movement relative to the base during a screening operation. The screens are pre-tensioned and mounted in a perimeter frame for separating various granular and particulate material. The frame is slid into the side of the machine in a direction parallel with two opposing bevel lips at the ends of the frame which mate in the screening machine with a complementary channel such that when the screen is raised into sealing contact in the screening machine, the bevel ends of the screen panel frame align the screen panel in the machine. The bevels on the screen panel frame provide a positive sealing surface for contact with the adjacent portions of the channel to prevent product from escaping off of the screen during use. | 02-17-2011 |
| 20120043262 | SANITARY GAPLESS SEPARATOR DISCHARGE - A particle size separator includes an upper separator frame, a lower separator frame, a screen disposed between the upper separator frame and the lower separator frame, a large size particle outlet having an inlet disposed below the screen, a small size particle outlet disposed in the lower separator frame and a combined baffle and seal unit disposed in an opening in the screen. The unit has a seal face configured to sealingly engage the inlet of the large size particle outlet. The unit has a baffle configured to constrain movement of particles on an upper surface of the screen into the inlet. The baffle is configured to sealingly engage an interior wall of the upper separator frame. | 02-23-2012 |
| 20120175288 | METHOD AND DEVICE FOR THE SELECTIVE CLASSIFICATION OF PARTICLES ACCORDING TO THE SIZE THEREOF - The invention relates to a method and to a device for the selective classification of particles according to the size thereof, determined by a maximum main dimension (a, b, c) of their particle geometric form, by means of classification using passage openings with a three-dimensional classification effect in a screening structure. | 07-12-2012 |
| 20120234735 | SIEVING DEVICE, SIEVING DEVICE FOR DEVELOPING DEVICE, AND POWDER-CHARGING DEVICE - A sieving device including a hollow cylindrical body, a filter disposed at a bottom portion of the hollow cylindrical body, and a blade configured to rotate in close proximity to the filter around a rotation axis thereof crossing the filter to thereby stir powder supplied to the hollow cylindrical body. | 09-20-2012 |
| 20130032512 | APPARATUS AND METHOD FOR ANALYZING AGGREGATE - A device, method, and system for analyzing aggregate are described. An exemplary device may include a housing with one or more grading screens. Aggregate and liquid may be received by a port within the housing. The liquid and any suspended fines, after passing through the one or more grading screens and aggregate, may be received into an observation container for observing the clarity of the liquid. | 02-07-2013 |
| 20130037454 | SCREEN LIFT MECHANISM FOR VARIABLE SLOPE VIBRATING SCREENS - A compact mobile variable angle vibrating screen with a suspension and dampening system configured to rapidly accommodate variable angles and exhibit acceptable vibration levels; especially during power up and power down surge vibration at the variable angles. The system comprises a group of bi-directional dual pivot leg vibration damper mechanisms, including nesting tubes, one with holes for receiving pins and the other with a semi-circular cutout at the bottom edge. | 02-14-2013 |
| 20140262976 | Heavy Machine-Operated Sieve Screen Bucket - The invention relates to a heavy machine-operated sieve screen bucket. A plurality of screening plates ( | 09-18-2014 |
| 209257000 | Conveyors | 4 |
| 20110192769 | COLLAPSIBLE MOBILE MATERIAL PROCESSING PLANT WITH FLEXIBLE HOPPER - A mobile collapsible screen and cone crusher combination where the screen is pivoted forward and downward for transport and a rubber hopper is coupled to the fines conveyor so as to permit a hinged connection and a sliding connection between the flexible hopper and the fines conveyor. A plurality of flexible matter edge plates are used at the rear of the flexible hopper to facilitate proper compression and expansion of the flexible hopper. A selectable maintenance catch is used to allow the screen to be elevated to an intermediate height for maintenance. | 08-11-2011 |
| 20130037455 | FINES SCALPING CHUTE FOR VARIABLE SLOPE VIBRATING SCREENS - A compact mobile variable angle vibrating screen with fines diverting systems configured to accommodate variable angles and still deliver material, via a plurality of partially nested fines chutes, to a fixed location despite angular adjustment of the vibrating screen. The system comprises a diverting pan attached to the underside and at a top end of a bottom screen and centrally positioned, such that fines material which quickly passes through the several decks encounters the diverting pan instead of falling directly onto a discharge conveyor. | 02-14-2013 |
| 20150129468 | Combined Auger and Screening Apparatus for Screening and Conveyance of Granular Fertilizer or the Like - A combined auger conveyor and screening apparatus features an inlet hopper mounted to an auger housing adjacent an inlet end thereof, and a screen support frame disposed atop the inlet hopper and supporting a screen over an area of the inlet hopper. A screen drive mechanism is removably mounted to the auger housing, coupled to the screen support frame and operable to drive oscillatory motion of the screen. An angle adjustment mechanism is operable to vary a position of ground wheels relative to the auger housing in order to change an inclination angle of the auger housing and screen relative to the ground. A hydraulic circuit supplying hydraulic motors for both the auger and the screen drive mechanism comprises a control valve operable to adjust an oscillatory speed of the screen support frame. | 05-14-2015 |
