1. Introduction
1.1 Scope
This manual is intended to be used as a guide and reference for personnel who will be installing, operating, and maintaining
the SEM security disintegrator. The purpose is to aid these individuals in applying efficient, proven techniques which will
enhance equipment productivity.
This introduction includes a brief functional description, a physical description, and machine specifications for these dis-
integrators. Additional sections within the manual provide instructions for installation, pre-operational procedures, opera-
tion, preventative maintenance, and corrective maintenance.
Installation instructions include all required data for receiving, unpacking, inspecting, and setup of the disintegrator.
Also included are illustrations which will aid in utilizing techniques to accomplish these tasks efficiently. SEM can provide
the assistance of a factory trained technician who will help in training your operator(s).
Pre-operational procedures include instructions, checks, and adjustments which should be followed before operating
the disintegrator. These instructions are intended to supplement standard shop procedures performed at shift, daily,
and weekly intervals.
The operation section includes a description of electrical and mechanical controls and information for operating the
disintegrator safely and efficiently.
The maintenance section is intended to serve both as a guide for identification and location of most common problems
and as a source of detailed assembly and disassembly instructions for those areas of the equipment requiring service.
The spare parts section contains a partial list of recommended parts which may require replacement. Refer to this sec-
tion for a listing of spares which can be purchased.
1.2 General Description
SEM security disintegrators are designed to uniformly and consistently shred material to a specified end particle size.
Disintegrators are portable units mounted on heavy duty bases fitted with four casters, two of which are lockable.
The rotor on which the cutting knives are mounted is a fabricated steel unit supported by bearings mounted outside the
cutting chamber. The rotor is driven by a motor which is capable of producing high torque loads. The disintegrator is
equipped with a magnetic starter that is protected by manually resettable overload heaters. The slanted rotor knives and
counter slanted bed knives produce a scissors cutting action which reduces the possibility of feedstock jamming in the
cutting chamber. Motors are individually fused for maximum protection in compliance with the National Electric Code
(NEC).
The control enclosure houses all of the necessary wiring, fuses, overload heaters, motor starter coils, along with
the 115V control transformer and disintegrator operating controls. The control enclosure is built to meet NEC
regulations.
