Spillage in load areas is a major problem in most facilities. The At-Last-A-Seal solves the problem by
providing a "live seal" between the belt and the structure. The seal moves freely on the chute wall, letting itself adjust and needing little or no maintenance. At-Last-A-Seal When the belt is loaded, material presses down on the inside slope of the At-Last-A-Seal, and this pressure creates the seal. As the belt load decreases and eventually empties, the pressure decreases so as not to wear the seal prematurely.
ATLASTASEAL is supplied in a continuous, seamless length to match your needs, there are no joints or seams that can leak or need additional maintenance. ATLASTASEAL also serves as a wear liner by encapsulating the lower portion of the chute wall.
Self-adjusting and low maintenance.
Requires no clamps or mounting brackets.
Flat At-Last-A-Seal is now available for flat belts. Standard At-Last-A-Seal is angled for troughed belts.
There are many applications for ATLASTASEAL , particularly in mining and iron industry, in which continuous conveyor belts are utilised to move bulk materials such as coal, grain, and the like from one location to another. In any system of this kind, the bulk material must be deposited on the moving conveyor belt; interruption of belt movement to receive a new load is economically infeasible.
ATLASTASEAL is Designed to fit as part of chute wall and float on belt.
65-75 durometer EPDM rubber.
Designed to fir as part of chute wall and float on belt.
There are many applications, particularly in mining and in industry, in which continuous conveyor belts are utilised to move bulk materials such as coal, grain, and the like from one location to another. In any system of this kind, the bulk material must be deposited on the moving conveyor belt; interruption of belt movement to receive a new load is economically infeasible.
At the discharge end, it is usually necessary to scrape or clean the belt to make sure that all of the bulk material is left at the desired new location. Both ends of such a continuous belt conveyor system presents substantial problems; this invention is concerned with the problems and difficulties that occur in depositing bulk material on the moving belt for transport to a distant location.
A major problem of the input station of any continuous conveyor belt system is leakage of the bulk material being transported by the system. Broadly speaking, this has been met to a substantial extent by resilient aprons affixed to rigid skirtboards around the input station. Examples previously known resilient skirtboard aprons and apron mounts are disclosed in Gordon U.S. Pat. Nos. 4,231,471, 4,436,446, 4,877,125, and 4,989,727.
Perhaps the best such skirtboard apron is the simple but effective device described and claimed in Gordon U.S. Pat. No. 4,989,727 and sold commercially under the designation ATLASTASEAL. Even that skirtboard apron, however, may have leakage problems, particularly as the result of appreciable movement of the conveyor belt, vertically or laterally, other than in the conveying direction through the input station.
Accordingly, the invention relates to an input station for a belt conveyor comprising a continuous conveyor belt of given width having a conveyor run extending through an input station to and around a head pulley at a discharge location, and a return run from the head pulley to and around a tail pulley back into the input station.
The input station comprises a frame, center belt support means having a width less than the belt width, mounted on the frame, for supporting the central portion of the conveyor belt throughout the input station; the center belt support means comprises a plurality of support rollers extending across and engaging the underside of the conveyor run of the conveyor belt throughout the input station.
The input station further comprises first and second lateral belt support means, each having a width less than the belt width, mounted on opposite sides of the frame adjacent the center belt support means; each lateral belt support means includes at least one belt support rail, extending parallel to the conveyor belt, engaging the underside of the conveyor run of the conveyor belt and supporting a lateral portion of the conveyor belt, with no appreciable sag, throughout the input station, at an acute angle to the central portion of the conveyor belt. The input station also has first and second input skirtboard means, positioned above opposite sides of the conveyor belt and each extending longitudinally of the belt, for sealing off the lateral edges of the conveyor belt at the input station.
