The Pyramid Approach
With over 50 years of experience in making bulk material handling cleaner safer and more productive Martin Engineering offers practical solutions to your belt conveyor problems.
By preventing spillage and airborne dust, Martin Engineering's Transfer Point Technology will reduce equipment damage, reduce cleanup, and control maintenance expenses.
But Martin Engineering is more than an equipment supplier. We have created and implemented a comprehensive approach for putting a stop to fugitive material. This system incorporates improved systems for Material Containment, Dust Suppression, and Dust Collection. It also includes significant contributions from the intangibles of Commitment, Knowledge, and Service. This philosophy is explained in Martin Engineering's book FOUNDATIONS2 The Pyramid Approach to Control Dust and Spillage From Belt Conveyors.
This page highlights the various hardware systems offered by Martin Engineering as components of the Pyramid Approach.
For more information about improving transfer points with The Pyramid Approach, see your Martin Engineering representative.
1. ENTRY AREA
In the entry area, the belt is prepared for loading. Here, the belt must be centered, wrapped around the tail pulley, and formed into a trough.
Keep the Belt Tracking True
To end mistracking, the patented MARTIN TRACKER Belt Tracking Systems automatically sense and continuously correct belt tracking. Use upper unit on carrying side of belt; install lower unit on return side.
MARTIN TRACKER Belt Tracking Systems
