Section 2 – Safety Considerations and Precautions

Before installing and operating the MHCP Primary Cleaner, it is important to review and understand the following safety information.

There are set-up, maintenance and operational activities involving both stationary and operating conveyors. Each case has a safety protocol.

2.1 Stationary Conveyors

The following activities are performed on stationary conveyors:

• Installation • Blade replacement • Repairs

• Tension adjustments • Cleaning

DANGER

WARNING

It is imperative that Lockout/Tagout (LOTO) regulations, be followed before undertaking the preceding activities. Failure to use LOTO exposes workers to uncontrolled behavior of the belt cleaner caused by movement of the conveyor belt. Severe injury or death can result.

Before working:

• Lockout/Tagout the conveyor power source

• Disengage any takeups

• Clear the conveyor belt or clamp securely in place

Use Personal Protective Equipment (PPE):

• Safety eyewear

• Hardhats

• Safety footwear

Close quarters, springs and heavy components create a worksite that compromises a worker’s eyes, feet andskull.

PPE must be worn to control the foreseeable hazards associated with conveyor belt cleaners. Serious injuries can be avoided.

2.2 Operating Conveyors

There are two routine tasks that must be performed while the conveyor is running:

• Inspection of the cleaning performance

• Dynamic troubleshooting

Every belt cleaner is an in-running nip hazard. Never touch or prod an operating cleaner. Cleaner hazards cause instantaneous amputation and entrapment.

Never adjust anything on an operating cleaner. Unforseeable belt projections and tears can catch on cleaners and cause violent movements of the cleaner structure. Flailing hardware can cause serious injury ordeath.

Belt cleaners can become projectile hazards. Stay as far from the cleaner as practical and use safety eyewear and headgear. Missiles can inflict serious injury.

3.1 Checklist

Section 3 – Pre-Installation Checks and Options

• Check that the cleaner size is correct for the beltline width

• Check the belt cleaner carton and make sure all the parts are included

• Review the “Tools Needed” list on the top of the installation instructions

• Check the conveyor site:

- Will the cleaner be installed on a chute

- Are there obstructions that may require cleaner location adjustments (see 3.2 – Cleaner Location Adjustments)

- Is the install on an open head pulley requiring mounting structure

(see 3.3 – Optional Installation Accessories)

Page 7

3.2 Cleaner Location Adjustments

Section 3 – Pre-Installation Checks and Options

In certain applications it is necessary to modify the location of the primary cleaner pole due to permanent obstacles that obstruct the desired location. Relocating the pole location can be done easily and does not hinder the performance of the cleaner as long as the “C” dimension is maintained.

NOTE: In the following example we will be lowering the pole location in the “Y” direction, but the same method could also be applied in the “X” direction.

Conveyor situation:

Pulley Diameter: 900mm

X = 450mm

Y = 359mm

C = 575mm

1. Determine the given location dimensions and define the change needed. After laying out the given X & Y dimensions, determine the distance of the modification required for adequate clearance of the pole and tensioning system. (In the example we decide to lower the pole 50mm to clear the support structure).

2. Write down known dimensions. We can now determine two of the three required dimension which will allow us to find the third. We know we cannot alter the “C” dimension, so this will remain the same. Also we are required to lower the unit in the “Y” dimension 50mm, so we add 50mm to the given “Y” dimension.

X = ? mm

Y =359+50=409mm

C = 575mm

3. Determine final dimension. On a flat vertical surface, using a level, draw one horizontal line and one vertical line creating a right triangle (Fig 3a). Measure down from the intersection the determined “Y” dimension and mark (Fig 3b). With the tape measure starting at the modified “Y” mark, swing the tape across the “X” line and mark at the “C” dimension where it crosses the “X” line (Fig 3c). Measure from the intersection to the “C” intersection and this will be your new “X” dimension (Fig. 3d).

X = 403mm

Y = 409mm

C = 575mm

Section 4 – Installation Instructions

Physically lock out and tag the conveyor at the power source

before you begin cleaner installation.

1. Find the X, Y & C specifications. Measure the pulley diameter (including the belt and the lagging) (Fig. 1).

Pulley Diameter _____

mm; X=_____mm; Y=_____mm; C=_____mm.

(Adjustments can be made to the X & Y coordinates to move away

from obstacles as long as the C dimension remains constant.)

CAUTION: Components may be heavy. Use safety-approved lifting procedures.

5. Install the mounting bases.

Bolt the mounting bases to the chute with the bolts provided (Fig. 5).

6. Install the blade cartridge.

Place the blade cartridge onto the centre pole. Adjust the extender poles until the holes align with the holes in

the centre pole and lock the cartridge into place with the two bolts, washers and nuts (Fig. 6). NOTE: Be sure at least 150mm of the extender

pole extends out of the mounting base on each side for tensioner installation. Adjust the extender poles in the centre pole if more or less length is needed.

Section 4 – Installation Instructions

2. Lay out the dimensions on the chute wall. Measure out the X dimension horizontally from the centre of the pulley shaft and mark. (NOTE: It may be easier to put a level on top of the pulley shaft, draw a horizontal line and then measure down half the diameter of the shaft and make a line from the front of the shaft. Now subtract half the pulley shaft diameter from the X coordinate and measure on the line and make a mark.) Then measure down vertically the Y dimension and mark. This is the correct position for the centre of the cleaner pole (Fig. 2). Lay out and mark the same dimensions on the other side.

3. Mark and cut the mounting base holes. Using the mounting base template provided in the instruction packet, position the large pole hole of the template on the chute with the hole notches aligned with the layout lines. Trace the pole hole and mounting holes (Fig. 3). Each base can be mounted in any position 360° around the pole as long as the pole’s centre point does not change. Cut the holes on both sides of the chute.

4. Assemble the extender poles to the centre pole. Insert the extender poles through the chute holes and into the centre pole and make sure the locating bolt holes align with the centre pole holes (holes are offset to the lower half). Position the centre pole with the welded nuts and locking bolts on one side facing down and on the adjoining side facing away from the head pulley (Fig. 4). Leave the locking bolts loose.

7. Centre the blades on the belt.

Slide the pole until the blades are centreed or cover the belt’s material path (Fig. 7). NOTE: Standard blade coverage is belt width minus 150mm. If less blade coverage is required, single blades can be removed from the blade cartridge. The blades do not have to be centred in the cartridge. They should be centred on the belt’s material path.

8. Lock the extender poles in the centre pole. Tighten the two locking bolts and jam nuts on each end of the centre pole (Fig. 8).

Install the tensioning system. For the PST Spring Tensioner go to step 9S. For the AWT Air/Water or PAT Tensioner proceed to step 9A.

9S. Install the torque pivot rod. Remove the

adjusting nuts and springs from the rods. The pivot rod base can be installed in any of the four mounting plate holes. Determine the rotation desired. Insert the pivot rod mounting bolt through the chute wall and the mounting plate and into the pivot rod base and tighten (Fig. 9S).

10S. Slide the torque arm onto the pole end. Again ensuring the

correct pulling rotation, put the torque arm onto the pole end and rotate it around until the torque pivot rod slides through the slot (Fig. 10S).

11S. Reassemble the spring assembly. Slide the spring, washer and

bushings onto the pivot rod and turn the two adjusting nuts so about 6mm of the rod is exposed above the nuts (Fig. 11S). Complete steps 9S through 11S on the other side.

12S. Tension the blades to the belt. Rotate the blades until they contact the

belt. While holding the spring bushing flat on the torque arm, rotate the torque arm until the pivot rod is against the end of the slot nearest the pole. Tighten the locking bolts and jam nuts on the torque arm (Fig. 12S).

NOTE: The torque arm should be up against the mounting base.

chart or the decal on the mounting base for the spring length required for the belt width. Lightly pull the pivot rod toward the end of the torque arm slot nearest the pole and turn the adjusting nuts until the required spring length is achieved (Fig.13S). Complete steps 12S and 13S on the other side. For best results, recheck the spring length on the first side to insure there has been no movement.

14S. Test run the cleaner. Run the conveyor for at least 15 minutes and

inspect cleaning performance. Check the spring lengths for proper tensioning. Make adjustments as necessary.

NOTE: Tensioners are shipped with the air bags and torque arms attached to the mounting bases.

9P. Tension the blades to the belt. Collapse both air bags (with C-clamps) and rotate

the blades until they are 25mm short of contact with the belt. Tighten the torque arm locking bolts and jam nuts (Fig. 9P).

10P. Connect the supply lines and set tension pressure.

With the parts supplied, attach a line to each air bag and run the lines to the outlet side of the PAT control box (Fig. 10P). NOTE: Be sure lines are safely away from the belt. Connect a line from the inlet side of the box to the site’s supply or air tank. Test the connections for leaks and set the pressure per the chart on the control box (also shown below). Take the pressure chart label from the instruction packet and affix it in an easily accessible location near the regulator for future reference.

Section 5 – Pre-Operation Checklist and Testing

5.1 Pre-Op Checklist

• Recheck that all fasteners are tightened properly

• Add pole caps

• Apply all supplied labels to the cleaner

• Check the blade location on the belt

• Be sure that all installation materials and tools have been removed from the belt and the conveyor area

5.2 Test Run the Conveyor

• Run the conveyor for at least 15 minutes and inspect the cleaning performance

• Check the tensioner spring for recommended length (proper tensioning)

• Make adjustments as necessary

NOTE: Observing the cleaner when it is running and performing properly will help to detect problems or when adjustments are needed later.

Page 13

Section 6 – Maintenance

Flexco belt cleaners are designed to operate with minimum maintenance. However, to maintain superior performance some service is required. When the cleaner is installed a regular maintenance program should be set up. This program will ensure that the cleaner operates at optimal efficiency and problems can be identified and fixed before the cleaner stops working.

All safety procedures for inspection of equipment (stationary or operating) must be observed. The MHCP Primary Cleaner operates at the discharge end of the conveyor and is in direct contact with the moving belt. Only visual observations can be made while the belt is running. Service tasks can be done only with the conveyor stopped and by observing the correct lockout/tagout procedures.

6.1 New Installation Inspection

After the new cleaner has run for a few days a visual inspection should be made to ensure the cleaner is performing properly. Make adjustments as needed.

6.2 Routine Visual Inspection (every 2-4 weeks)

A visual inspection of the cleaner and belt can determine:

• If the spring length is the correct length for optimal tensioning.

• If the belt looks clean or if there are areas that are dirty.

• If the blade is worn out and needs to be replaced.

• If there is damage to the blade or other cleaner components.

• If fugitive material is built up on the cleaner or in the transfer area.

• If there is cover damage to the belt.

• If there is vibration or bouncing of the cleaner on the belt.

• If a snub pulley is used, a check should be made for material buildup on the pulley.

If any of the above conditions exist, a determination should be made on when the conveyor can be stopped for cleaner maintenance.

6.3 Routine Physical Inspection (every 6-8 weeks)

When the conveyor is not in operation and properly locked and tagged out a physical inspection of the cleaner to perform the following tasks:

• Clean material buildup off of the cleaner blade and pole.

• Closely inspect the blade for wear and any damage. Replace if needed.

• Check both cartridges for proper installation and condition. Replace if needed.

• Ensure full blade to belt contact.

• Inspect the cleaner pole for damage.

• Inspect all fasteners for tightness and wear. Tighten or replace as needed.

• Replace any worn or damaged components.

• Check the tension of the cleaner blade to the belt. Adjust the tension if necessary using the chart on the cleaner or the one on Page 11.

• When maintenance tasks are completed, test run the conveyor to ensure the cleaner is performing properly.
