High Performance Polyurethane Belt Cleaner for Conveyor Systems in Mining

Working Principle of the Polyurethane Scraper

When the conveyor belt is running, the polyurethane scraper is installed in close contact with the surface of the conveyor belt. The scraper is usually held in place by a suitable mounting mechanism.

As the conveyor belt moves, the polyurethane material of the scraper exerts a certain pressure on the belt surface. Due to the elasticity and wear resistance of polyurethane, it can conform to the irregularities of the belt and effectively scrape off adhered materials such as dust, dirt, small particles, and moisture.

The scraper's design and pressure ensure that it can remove as much of the unwanted material as possible without causing excessive damage to the conveyor belt. The scraped materials are then directed away from the belt, either falling into a collection bin or being discharged in a controlled manner.

In summary, the polyurethane scraper works by using its unique material properties and proper installation to continuously clean the conveyor belt surface as it operates, improving the efficiency and longevity of the conveyor system.

Conveyor Cleaner Introduction

I. Working Principle

The conveyor cleaner is a device used to clean the adhering substances on the surface of the conveyor belt and plays an important role in industrial production. The main working principles are as follows:

1. Scraper cleaner:

Utilizes the friction between the hard scraper and the surface of the conveyor belt to scrape off the adhering materials. The scraper is usually made of wear-resistant materials such as polyurethane or rubber.

2. Brush cleaner:

Adopts a soft brush to contact the conveyor belt. Through the rotation or swing of the brush, the materials are brushed off. The materials of the brush include nylon, steel wire, etc.

3. Air blow cleaner:

Uses the airflow generated by compressed air to blow off the impurities on the conveyor belt.

II. Types and Characteristics

1. Head cleaner:

Installed at the head pulley of the conveyor. It is mainly used to remove most of the adhering materials on the conveyor belt.

Usually has strong cleaning ability and wear resistance and can withstand large pressure and friction.

Common types of head cleaners include counterweight type, spring type, polyurethane scraper, etc.

2. Empty section cleaner:

Installed near the tail pulley of the conveyor or in the empty section between the return idlers.

Used to remove a small amount of residual materials on the surface of the conveyor belt when it returns, preventing materials from spilling and accumulating during the return journey.

Generally in the form of rubber scraper or brush, with a relatively simple structure.

3. Combined cleaner:

Composed of a head cleaner and an empty section cleaner, it can achieve a more thorough cleaning effect.

Suitable for occasions with high cleaning requirements for conveyor belts, such as transporting viscous materials and wet materials.

III. Functions

1. Improve the service life of the conveyor belt:

Timely remove the adhering substances on the conveyor belt to reduce wear and corrosion on the conveyor belt and extend its service life.

Avoid conveyor belt deviation and tearing failures caused by material accumulation.

2. Keep the working environment clean:

Prevent materials from spilling and flying, reduce environmental pollution, and improve the hygiene conditions of the workplace.

Reduce the labor intensity of workers and improve work efficiency.

3. Improve conveying efficiency:

Ensure that the surface of the conveyor belt is clean, reduce the friction between materials and the conveyor belt, and reduce energy consumption.

Avoid conveyor belt slippage caused by material adhesion and ensure the stable operation of the conveying system.

IV. Installation and Maintenance

1. Installation:

The installation position of the cleaner should be accurate to ensure good contact with the conveyor belt.

When installing, pay attention to adjusting the pressure and angle of the cleaner so that it can effectively clean without excessive damage to the conveyor belt.

Install correctly according to the equipment instruction manual to ensure firm and reliable installation.

2. Maintenance:

Regularly check the wear condition of the cleaner and replace severely worn parts in time.

Keep the cleaner clean and prevent blockage by debris from affecting the cleaning effect. Check whether the installation bolts of the cleaner are loose. If loose, tighten them in time.

Perform lubrication and maintenance on the cleaner to extend its service life.

In conclusion, the conveyor cleaner is an indispensable important device in the conveyor system. It can effectively improve the service life of the conveyor belt, keep the working environment clean, and improve conveying efficiency. When choosing and using a cleaner, select the appropriate type according to the actual situation and perform correct installation and maintenance.
