Primary Belt Cleaners & Scrapers

Primary belt scrapers are designed to remove debris known as ‘carryback’ from the belt surface, which can otherwise be transferred to the rest of the conveyor system. This causes extra wear and tear, and potentially shortens the life of the conveyor.

Primary belt scrapers can consist of either a single blade which passes along the width of the belt, or a series of short blades, with different blade material available to suit the individual system. They are installed at the head pulley, and can have adjustable torque or suspension systems to allow continuous contact with the belt surface at all times.

Secondary Belt Cleaners & Scrapers

The secondary cleaner is usually used in addition to a primary scraper. It is normally installed between the drive pulley and the first supporting roller to give the most effective performance, and clear any smaller waste particles which were not picked up by the primary cleaner.

There are several different types of belt cleaner and scraper available, to suit different types and sizes of machine, and the type of material transported. Secondary cleaners can be used without the primary cleaner, for example if the material is dry and fine.

Non Contact Srape Air

Moist to sticky materials are most suited to non-contact systems, which use an air suction method to remove spillages from the conveyor surface. They can also be used with a spray bar for effective cleaning of dry and dusty materials.

Non-contact scrape-air conveyor belt cleaners cause no belt wear because they do not have any mechanical contact with the belt. They are a cost-effective and low maintenance solution for chevron belts and damaged belts, and are ideal for acidic materials.

They can be supplied with self-cleaning filters to minimise maintenance costs, and are also available with bypass regulators to control delivered air volume.

Chevron

The Chevron secondary conveyor belt cleaners are specially designed for chevron, raised-rib, or cleated conveyor belt surfaces, which are difficult to clean with other methods.

If material is allowed to build up on the belt surface, it leads to carryback, which causes extra wear and tear on the rollers and drum. This increases maintenance costs. and shortens the life of the machine.

Chevron belt cleaners have rotating rubber discs which move in a sweeping action to remove debris, and can either be solid or notched to suit the conveyor belt speed and the spacing of the chevrons. They are suitable for wood processing, mineral, mining, and recycling plants.

The Hoverdale motorised brush is designed to clean a range of belt constructions including

  • Chevron belts
  • Cleated belts
  • Flighted belts
  • Vulcanised or mechanical joined

The rotation action working against the belt’s direction is designed to dislodge material stuck between the chevron patterns, cleats , and also very effective on flat belts.

Replacement Blades

High quality primary belt cleaner blades are important to ensure the best cleaning performance. Replacement blades are available for a wide variety of belt cleaning systems, and are effective at removing spillages and debris from the belt surface.

Ineffective belt cleaners, either because the blades need replacing or because the cleaner isn’t suitable for the system and material type, leads to damage to the conveyor system. This can mean unscheduled downtime, extra maintenance work, and increased safety risks. Therefore, it is important to replace blades when the show signs of wear.

Belt Cleaners & Scrapers: A Quick Guide

Keeping conveyor belts free from waste remnants is a widely recognised problem in processing plants. If particles are not fully removed, it can cause material build-up on the conveyor surface, which is transferred to the return rollers and tail drum, a problem known as ‘carryback.’

Conveyor belts which are not kept properly clean are prone to tracking issues and damage to the belt, which means more downtime and higher maintenance costs. This is why it’s important to install the most effective primary and secondary belt cleaners and scrapers for the type of machine, and the materials it handles.

Belt scrapers are used throughout a wide variety of industries. They are commonly found in recycling and material sorting plants, and the wood chipping, mineral processing, mining, and scrap metal sectors.

Primary belt scrapers are the first line of defence against material build-up, and they are designed to remove residual material after the belt has unloaded. Primary scrapers are especially suited to removing coarse particles, and gels and liquids. Secondary scrapers are used to remove any remaining residue after the primary scraper has passed along the belt.

There are a number of different designs, to take into account different plant uses. For example, some belt scrapers are designed to work at lower or higher belt speeds, and with different types of belt surface, such as ridged or chevroned. Other factors which might affect the choice of scraper include the working environment and temperature.

The belt scraper can also be selected so that it is the best fit for the type of materials transported. For example, the moisture content, acidity or alkalinity levels, the consistency, such as fine powder or heavy clays, and the particle size. They are typically made of plastic, rubber, or metal, and can consist of a multi-blade system, or a single blade.

For material which is of a wet or sticky consistency, non-contact scraper air systems may be the best solution. These use an air suction method to remove materials from the belt surface. They are also suitable for removing fine, dusty or powdery materials from the belt surface, when used in conjunction with a spray bar.

Non-contact scraper air systems have the advantage of causing no damage to the belt, so they are ideal for harsh and abrasive materials, and will work effectively on damaged belts.

As well as selecting the right cleaner, it is important that they are installed correctly, and inspected regularly for signs of wear and tear. The abrasive nature of the scraping and cleaning process means that even good quality products will occasionally need adjusting or blades replacing to ensure that they are performing to a high standard.

A belt which is old or in a poor condition will also affect the performance of the cleaner and scrapers. The better the cleaners and conveying system are maintained, the more effective they will be, and the plant will have less downtime and increased productivity and profitability.

Frequently Asked Questions

Many companies offer only one system and it is well known that one system will not be at its best in all situations. Hoverdale are ‘armed’ with 13 systems each with different blade options and backed by 40 years’ experience at problem solving. We are confident that we can provide the results that you expect.

The largest system we have made was for a 4m belt which has been working perfectly for 2 years.

We can offer an air knife that will remove carry back without touching the belt.

We can offer a product specifically designed to resist acid attack which we will guarantee to do the job.

Yes we can. We will offer long life systems that will run for long periods without maintenance. The longest is 8 years – could be a world record!

Our Offer To You

Operating a bulk material handling plant is an expensive business made more difficult by excessive down time and costly maintenance. It is important that the best possible equipment and materials are used to minimise these difficulties which is where Hoverdale’s area of experience lays.
