Abstract:

The method and system of the present invention provides for fast, convenient and low cost installation and removal from a particulate screening assembly of an apparatus for protecting the underlying structural members of the screening assembly from the adverse affects caused by the flow therethrough of particulate material. The subject system includes a wear protector system designed for direct attachment to and removal from the structural members which support the screening assembly. This direct attachment and removal operation occurs without the need to detach or disassemble the support structure from the screening assembly. Thus, the wear protector system can be readily removed and replaced without expending substantial downtime in completing system maintenance.

Abstract:

A system for screening particulate material includes replaceable screening modules mounted to a rigid frame by lock pins. The lock pins are fixed into mounting holes in the frame and interlockingly and removably engage recesses in the sidewalls of the screening modules so that the lock pins remain fixed to the frame while allowing the modules to be removed and replaced as required due to wear or to change sieve size. A split lock pin is provided for removably connecting the module to the frame along an outboard edge of the frame while maximizing screening area. An improved elongate frame member is arranged to avoid abrasive wear of the frame.
