Martin Engineering is the world’s leading developer and manufacturer of engineered conveyor belt cleaning / conveyor belt scraping systems. In this position, Martin Engineering has developed fundamental principles of belt cleaner / belt scraper design that have set standards for belt cleaner / belt scraper engineering and performance.

Generally, this philosophy calls for belt cleaners / belt scrapers that are:

• As far forward (as close to the conveyor discharge) as possible.
• Positioned out of the material flow.
• Designed to minimize risk to belt, splice, and cleaner itself.
• Designed to stand up to “worst case” conditions.
• Designed for ease of maintenance, including simple blade replacement and reduced frequency of re-tensioning.

To provide effective cleaning, Martin Engineering is the pioneer of the Multiple Cleaner System, consisting of:

Pre-Cleaner
• Installed on the face of the head pulley below the discharge trajectory, this cleaner uses low pressure to remove approximately 75 to 90 percent of the residual material.

Secondary Cleaner(s)
• Installed at the point where the belt leaves the head (discharge) pulley, or further along the return where space permits, these systems remove the remaining material. Additional (tertiary) cleaners are installed as required by conditions.

The multiple-cleaner system originally adopted by Martin Engineering is now the standard for applications on belt conveyors carrying all types of bulk materials around the world. End-users (and other cleaner manufacturers) have accepted it almost universally
