ABSTRACT:
A slide gate assembly for use in maintaining a dust free environment is disclosed. The assembly includes a slide gate and a dust cover which operate to allow the passage of particulate or other material into or out of a bin or other container. In one embodiment, the gate is slidably mounted in a frame which is formed by a plate member, upper and lower base members and upper and lower gasket members. In one embodiment, some of the components are of neoprene while other components are of UHMW, thus providing resilient properties and also self-lubricating properties for the slide gate assembly. The gate assembly is maintained in a dust tight condition by means of controlled compression obtained through the use of bolts or screws which extend through the plate member, the base members and the gasket members.
