4. Site Preparation
A Professional Engineer must follow this section for proper site design.
Serious injury or equipment failure can result from a lack of proper site design.
4.1. Site Layout
Check the following when developing the site layout where a conveyor is installed:
• Access for maintenance and repair.
• Clearance to material inlets.
• Clearance to other structures.
4.2. Foundation
The foundation for the chain conveyor must be designed based on allowable soil bearing loads. The foundation
should be uniform and level. Any variance from level must be shimmed at the conveyor support.
4.3. Supporting Structures
The installer is responsible to provide proper support for the conveyor. Design of structural supports must be
reviewed by a professional engineer.
When planning for supports, consider:
• overhead clearance
• accessibility for maintenance
• building movements
Note
Movement of buildings must not affect the conveyor. For example, use telescoping spouting to and
from the conveyor to prevent movement.
• strength of supports
• location of supports
Note
Support the conveyor at its strongest point. Add structural support at the flanged joints every 10’ or
use sound engineering judgement. If the conveyor is on a catwalk, ensure the conveyor supports
land on catwalk structural members.

DRAG CONVEYORS 4. SITE PREPARATION

20 8210-30002 R0
4.5. Location of Spouting and Dust Control
Connected Equipment
The conveyor inlet and discharge openings are designed to connect to spouting or transitions from other
equipment.
• It is critical that inlet spouting be designed to not cause side loading of the conveyor, or restrict capacity in
to the inlet section.
• It is critical that the discharge spouting be sized and designed so as not to restrict full capacity discharge of
the conveyor.
• Discharge spouting loads should not be supported by the conveyor head section.
Dust Control
Excessive dust in the tail, trunk, and head sections may cause a dust explosion under certain conditions.
Excessive air, particularly in the tail section, will expel dust through the gaskets and shaft seals. It is the
responsibility of the owner and/or installer to provide relief for the air and dust in the conveyor. This air relief is
generally introduced at the tail section, intermediate section(s), head section, or in all three locations. The
amount and type of equipment used to provide the air and dust relief is relevant to the customer and/or the
safety standard requirements of the company or local authorities.
The conveyor cannot achieve the type of seal that would be attributed to that of a pressure vessel. Excessive air
pressure in the conveyor in combination with the product will create a dusty environment both inside and
outside the conveyor.
4.6. Electrical Requirements, Controls, and Devices
Electric motors and controls shall be installed and serviced by a qualified electrician and must meet all local
codes and standards.
When providing power to the electric motor:
• Place main power disconnect switches at a convenient location to permit ready access in case of an
emergency.
• Ensure that the motor is electrically grounded.
• Provide appropriate electrical controls that meet all specifications of the conveyor.
• Use an interlock when the conveyor is mechanically connected to other equipment.
The following safety devices should be installed:
• Overload protection for devices (shear pins, torque limiters, etc.) and no speed protection (zero-speed
switches) to shut off power in the event of an incident that might cause the conveyor to stop operating.
• Emergency stop switches that are readily accessible.
• Signal devices to warn personnel of imminent start up, especially if started from a remote location.
Conveyors are commonly equipped with devices listed below, and these may be required by local fire codes. AGI
recommends these safety devices.
