Introduction

General To introduce product back into the product flow, a Pre-Cleaner is installed on

the face of the head pulley. On a dual cleaner system, the Secondary Cleaner is installed immediately following the Pre-Cleaner to remove stubborn material left on the conveyor belt. If a Pre-Cleaner cannot be used because of space limitations, the Secondary Cleaner is installed alone. If the materialhandling process or product could be affected by contamination from the use of these belt cleaners, the user is responsible for taking the necessary steps to prevent contamination. Consult Martin Engineering or a representative for alternate belt cleaners or belt cleaner locations to use where contamination may be an issue.

Introduction

Installations without chutework

Belt cleaner inspection access

These procedures were written for equipment that is being installed on enclosed pulley chutework. If the pulley is not enclosed, the equipment should be installed using the best available field resources and methods to ensure that the critical dimensions are followed for proper installation.

If the belt cleaner is installed on enclosed pulley chutework, a MARTIN® Inspection Door should be installed. MARTIN available from Martin Engineering or a representative. See “Part Numbers” for a list of MARTIN

Inspection Doors and part numbers.

DANGER

WARNING

Introduction

rules must be strictly followed when working on the belt cleaner.

Do not touch or go near the conveyor belt or conveyor accessories when the belt is running. Your body or clothing can get caught and you can be pulled into the conveyor, resulting in severe injury or death.

Before installing, servicing, or adjusting the belt cleaner/ tensioner, turn off and lock out/tag out all energy sources to the conveyor and conveyor accessories according to ANSI standards. Failure to do so could result in serious injury or death.

If this equipment will be installed in an enclosed area, test the gas level or dust content before using a cutting torch or welding. Using a torch or welding in an area with gas or dust may cause an explosion resulting in serious injury or death.

Before using a cutting torch or welding the chute wall, cover the conveyor belt with a fire retardant cover. Failure to do so can allow the belt to catch fire.

Remove all tools from the installation area and conveyor belt before turning on the conveyor. Failure to do so can cause serious injury to personnel or damage to the belt and conveyor.

Martin Engineering M3735-03/09 2 MARTIN

Mainframe with blade can be heavy and may require two people to lift. Attempting to lift the belt cleaner without assistance could result in injury.

Before Installing Belt Cleaner

IMPORTANT

DANGER

IMPORTANT

NOTE

The delivery service is responsible for damage occurring in transit. Martin Engineering CANNOT enter claims for damages. Contact your transportation agent for more information.

1. Inspect shipping container for damage. Report damage to delivery service immediately and fill out delivery service’s claim form. Keep any damaged goods subject to examination.

2. Remove belt cleaner assembly from shipping container.

3. If anything is missing contact Martin Engineering or a representative.

Before Installation

4. Turn off and lock out/tag out energy source according to ANSI standards (see “References”).

5. If using a cutting torch or welding, test atmosphere for gas level or dust content. Cover conveyor belt with fire retardant cover.

Center the belt cleaner blades to clean an area narrower than the conveyor belt width. This allows for side-to-side movement of the belt and prevents damage to the belt edge.

The chute wall that the tensioner will be located on is referred to as the “operator side.” The other side of the chute is referred to as the “far side.” (If installing dual tensioners, side that is most accessible is “operator side.”)

6. Determine which side of chute is easiest to access. Locate the tensioner

After Installing Belt Cleaner

WARNING

DANGER

1. Thoroughly wipe chute wall clean above tensioner.

2. Place Conveyor Products Warning Label (P/N 23395) on outside chute wall visible to belt cleaner operator.

Failure to remove tools from installation area and conveyor belt before turning on energy source can cause serious injury to personnel and damage to belt.

After Installation

Do not touch or go near conveyor belt or conveyor accessories when conveyor belt is running. Body or clothing can get caught and pull body into conveyor belt, causing severe injury or death.

3. Turn on conveyor belt for 1 hour, then turn off.

4. Make sure all fasteners are tight. Tighten if necessary.

5. Inspect belt cleaner for the following:

• Wear. (A small amount of “break-in” wear may be found. This will stop once blades wear to conveyor belt contour.)

• Material buildup. (No material between blades and return side of conveyor belt should be found.)

6. If wear, material buildup, or some other problem exists, see “Troubleshooting.”

WARNING

DANGER

Weekly Maintenance

Read entire section before beginning work.

Maintenance inspection should be performed no less than weekly. Some applications may require more frequent maintenance inspections.

1. Remove any material from belt cleaner.

2. Make sure all fasteners are tight. Tighten if necessary.

3. Check tension on cleaner. Re-tension if necessary.

4. Wipe all labels clean. If labels are not readable, contact Martin Engineering or a representative for replacements.

5. Check blades for excessive wear. Replace if necessary.

6. Remove equipment from service if there is any indication it is not functioning properly. Call Martin Engineering or a representative for assistance. Do NOT return equipment to operation until the cause of the problem has been identified and corrected.

7. Remove all tools from maintenance area.

8. Start conveyor belt.

Martin Engineering M3735-03/09 10 MARTIN

Failure to remove tools from installation area and conveyor belt before turning on energy source can cause serious injury to personnel and damage to belt.

Do not touch or go near conveyor belt or conveyor accessories when conveyor belt is running. Body or clothing can get caught and pull body into conveyor belt, causing severe injury or death.

Troubleshooting

NOTE

Symptom Corrective Action

Insufficient cleaning and carryback.

Noise or vibration.

High blade wear rate. Tension of cleaner on belt is set too high. Reduce tensioner setting.

Unusual wear or damage to blades.

Bent or broken mainframe or support frame due to blade slipping through.

Corrosion or chemical degradation.

• Tension of cleaner on belt is set too low or too high. Increase or decrease tensioner setting.

• Blades are worn. Check blades and replace if necessary.

Tension is not sufficient or is set too high. Correct tension as necessary. If this does not correct problem, blade urethane may not match application. Contact Martin Engineering or representative.

Check belt splice(s) and repair as necessary.

If blades are worn to or past the wear line, replace blades. If blades are not worn, check mainframe location.

Blade urethane may not match application. Contact Martin Engineering or representative.

Troubleshooting

Conveyor equipment such as conveyor belt cleaners are subject to a wide variety of bulk materials

characteristics and often have to perform under extreme operating or environmental conditions. It is

not possible to predict all circumstances that may require troubleshooting. Contact Martin

Engineering or a representative if you are experiencing problems other than those listed in the

“Troubleshooting” chart above. Do not return the equipment to operation until the problem has been

identified and corrected.

Installation checklist

✓ Pre-Cleaner mainframe is proper distance from belt surface on both ends of mainframe.

✓ Pre-Cleaner blade tip is at or below horizontal center line of pulley and does not lie in path

of material flow.

✓ Blades are centered on belt.

If after taking the corrective actions suggested under “Troubleshooting” you are still experiencing problems, check for the following:
