The conveyor belt is the workhorse of the load zone. It serves production goals with great endurance and resilience in moving tons of bulk material nonstop over long distances for extended periods.

As it continues performing within often demanding conditions, the conveyor belt will inevitably develop and encounter obstacles that can affect it as well as other system parts and areas.

To get greater service and life from the conveyor belt, operators need to be vigilant about keeping it clean. In particular, they must prevent carryback, the fugitive material that sticks to the belt beyond the discharge point and remains on the bottom side of the belt, rollers, or pulleys.

In addition to creating multiple health and safety risks, carryback can form a crown or raised portion on a pulley, making the belt misalign. As the mistracked belt keeps drifting, it will induce even more-serious spillage and dust. This will further increase hazards while demanding more company resources for housekeeping and maintenance.

Operators can avoid the problems of material build-up with a well-engineered conveyor belt cleaning system.

How to Keep Conveyor Belts Clean

Different operations face different carryback challenges according to their applications. Steel, gold, aggregate, and fertilizer, to name but a few, will often require their own belt cleaning strategies.

Whatever the bulk material might be, well-engineered conveyor belt cleaners keep the belt as clean as possible by removing excess material that builds on and clings to it. An optimal conveyor belt cleaning system will usually include two conveyor belt scrapers: a primary belt cleaner and a secondary belt cleaner.

Mounted to the head pulley below the material flow, the primary belt cleaner – also referred to as a pre-cleaner – scrapes excess material from the conveyor belt. In particular, it removes the larger pieces that constitute two-thirds of initial carryback.

Ideally, the primary belt cleaner will be made of a durable material such as urethane, which will act similarly to a metal blade–type scraper without metal’s risk of damage to the belt. The belt cleaner should offer adaptable mounting with a modular, compact design as well. Its profile will provide a varying attack angle to reduce blade-edge bull-nosing. A torsion tensioner also will self-adjust to maintain steady cleaning as the blade wears.

Located right past where the belt leaves the head pulley and anywhere else down the belt line, secondary belt cleaners scrape whatever material remains on the belt beyond the head pulley, especially fines.

Like the primary belt cleaner, the secondary blade can be made of material such as tungsten carbide or rubber. To avoid build-up, the correct secondary cleaner selection will depend on the conveyor belt’s characteristics.

With a secondary belt cleaner installed, the conveyor belt scrapers can achieve a cleaning efficiency of greater than 90%. By eliminating carryback and keeping belts clean, high-performing belt cleaners make conveyor systems both safer and more productive.

Belt cleaner blades (including replacement blades) can be customized to a bulk material handling system’s distinctive variables, including:

An effective conveyor belt cleaner system might also include specialty cleaners such as:

Clean Conveyor Belts Are Good Business

Bulk material handlers that are committed to a thorough, precisely engineered conveyor belt cleaning system reinforce their operational objectives in multiple ways:

• Greater profitability. Operators know the impact that extra housekeeping and maintenance can have on the bottom line. Minimizing or eliminating carryback significantly lowers the time, effort, and cost of dealing with fugitive material.
• Safer work environment. Spillage and dust from excess product create multiple dangers. Workers can easily slip and fall when navigating through spillage. Airborne dust can cause vision and respiratory problems and can even ignite an explosion.
• Longer-serving conveyor components. Carryback often makes its way into the conveyor system, where it can damage rollers and idlers while causing the belt to mistrack. By clearing equipment and the area of fugitive product, a belt cleaning system helps prevent early wear and extends service life.
• More kept material. Because they scrape the conveyor belt at the head pulley, belt cleaners keep a much greater amount of bulk material flowing in the proper direction through transfer points and into containers.
• Reduced energy costs. When bulk material sticks to the head pulley, the extra weight forces the equipment to work harder and draw more energy. A clean conveyor belt can work much more efficiently and notably lessen energy costs.

Advantages of Clean-in-Place Conveyor Belt Cleaning

In every food and beverage company, production hygiene is paramount to ensure product safety. For this reason, all equipment that comes in contact with the food or beverage product must be adequately cleaned and sanitized, and operating in top working condition at all times. One area of particular focus and historically time-consuming to clean are conveyor belts.

What is Clean In Place (CIP)?

Like other specialty manufacturing, food production requires the highest level of hygiene during all instances of production. “Clean in place” (CIP) is cleaning or sanitation systems that are designed to clean without having to remove the underlying items, in this case, conveyor belts. CIP technology developed particularly for conveyor belt cleaning in food and pharmaceutical producing companies allows production to continue and reduces downtime and cleaning costs. Due to strict oversight, there is a need to ensure non-contamination when cleaning conveyor belts. Opting for the CIP is the best decision that guarantees profit by saving time and labor without compromising the safety and quality of all goods produced.

Advantages to Clean in Place Belt Cleaning Solutions

Speed and Efficiency

CIP systems help to immediately save time and labor costs, making it much faster than manual cleaning. It reduces the production downtime, increases production capacity translating into more products, sales, and profitability. One company even saved over $79K in indirect labor cost after installing clean in place conveyor belt systems on their lines.

Reliability

With CIP systems, the benefits of cleaning and sanitation are apparent. Continued testing for pathogens is always suggested, but CIP systems do tend to offer more reliability.

Safety

No doubt, safety is of top priority when it comes to food production. When CIP belt cleaning systems are in use, they can clean more efficiently than the human eye. Since , the FSMA increased the need for cleaning equipment that typical hand cleaning cannot keep up with. It also can help reduce the tendency of accidents such as slipping and falling during cleaning.

Dry Steam and CIP – The Perfect Pair

When CIP belt cleaning systems are paired with dry steam, it produces a perfect cleaning duo. Dry steam is superheated steam with all the cleaning and sanitizing power of “Wet” steam, but only a 5% moisture content. It obliterates oils, soils, allergens, and more and leaves surfaces clean and dry.

CIP dry steam cleaning systems also reduce water consumption up to 98% vs. traditional wet cleaning systems. If the reduction in water consumption is a corporate initiative for your business, dry steam should be an immediate focus area.

THE FACTS ABOUT STEAM

• Thoroughly clean and sanitize conveyor belts without the use of chemical cleaners that could be toxic.
• Dry steam at a temperature of about 290 °F cleans grime, oils, kills microbes on contact, and leaves the belt dried almost instantly.
• Since little or no water is left after using dry steam, there’s little t worry about the growth of mold, bacteria, and other pathogens.
• Use up to 98% less water than other cleaning systems.

The Bottom Line

Better cleaning in less time that delivers more profitability. CIP solutions for belt cleaning offer almost immediate ROI, with most having 100% ROI in months, not years. Not only is it evident that manual cleaning of conveyor belts is time-wasting, but it’s also less efficient and prone to cause mistakes that could ruin the integrity of your food or beverage product.
