Paper mill conveying areas can involve high humidity, wet materials, washdown water, and process chemicals. Wet and fibrous pulp can also adhere to the belt surface, increasing carryback and cleaning requirements.

For these conditions, Corrosion and Moisture Resistant Conveyor Belts for Paper Mill Environments should combine suitable environmental resistance with the construction required for continuous conveying.

Prolonged water exposure can affect belt reinforcement and bonding between layers when the belt construction is not suitable for wet service. Chemical resistance and corrosion protection are related but different considerations. Chemical resistance mainly concerns the belt materials and cover, while corrosion protection may also apply to exposed metallic components.

Moisture Resistance

Moisture-resistant construction is important for wet pulp, recycled paper, wood chips, and other water-containing materials. The required level depends on humidity, splashing, washdown, or continuous wet operation.

Chemical Resistance

Corrosion and Moisture Resistant Conveyor Belts for Paper Mill Environments may be selected where the belt contacts process chemicals or cleaning agents. Chemical compatibility depends on the actual chemical, concentration, temperature, and exposure frequency.

Abrasion and Impact Resistance

Wood chips and other bulk materials can create repeated abrasion and impact. Belt cover properties should therefore be matched to particle size, material characteristics, loading conditions, and conveying speed.

Wet Pulp Conveying

Wet pulp can remain on the belt surface and increase carryback when the belt surface and cleaning arrangement are not properly matched. Moisture resistance, surface characteristics, and cleaning should therefore be considered together.

Wood Chip Handling

Wood chips can create impact and abrasion, while storage or processing may introduce additional moisture. In wet conditions, slippage, mistracking, and material spillage can also become concerns.

Different areas of a paper mill should not automatically use the same belt construction. The operating conditions at each conveying point should determine the specification.

Selecting Corrosion and Moisture Resistant Conveyor Belts for Paper Mill Environments should begin with the complete conveying condition.

Conveyed Material

Identify the material, moisture content, particle size, abrasiveness, and tendency to adhere to the belt.

Moisture and Chemical Exposure

Determine whether the conveyor handles wet material, operates in a humid area, or is exposed to washdown water or chemicals. When chemicals are involved, provide the chemical type, concentration, and operating temperature.

Conveyor Conditions

Important parameters include belt width, thickness, conveyor length, belt speed, conveying capacity, incline angle, loading conditions, and pulley arrangement.

Cleaning Requirements

For wet or sticky materials, the belt surface and cleaning system should be selected together to reduce carryback and buildup around the discharge and return path.

Even Corrosion and Moisture Resistant Conveyor Belts for Paper Mill Environments require regular inspection. Check the belt for abnormal wear, cracks, edge damage, swelling, and tracking problems.

For wet or sticky materials, inspect belt cleaners and remove accumulated material from the return path and pulley areas to reduce carryback and surrounding component wear.

What type of conveyor belt is suitable for wet pulp and recycled paper?

The appropriate belt depends on the material, moisture level, chemical exposure, abrasion, conveyor load, and operating conditions.

Can one belt provide moisture and chemical resistance?

Some constructions can provide both properties, but compatibility depends on the actual chemical, concentration, temperature, and exposure conditions.

Can belt dimensions be customized?

Yes. Belt width, thickness, tensile strength, surface design, and other specifications can be selected according to the conveyor system.
