The main job of a Conveyor Belt Scraper is to keep things clean and working well. This tool helps you avoid spending money on repairs and stops the system from breaking down. Picking the right scraper protects your equipment and makes your work better.
A Conveyor Belt Scraper is important for making sure the conveyor works well. Scrapers take off materials that stick to the belt. If you let stuff build up, the system does not work as well and needs more fixing. Scrapers stop these problems by cleaning the belt after every load.
Scrapers also make things safer. If material builds up, it can cause accidents or slow down work. Scrapers help stop these problems and keep things running smoothly. If you pick and take care of scrapers, your system works better and breaks down less.
Tip: Check your scrapers often to make sure they are working right. Doing this can save you time and money.
Scrapers do more than just clean. They are needed to keep your conveyor system safe, working well, and reliable.
Primary scrapers sit at the head pulley of the conveyor. This is where the belt drops off its main load. The scraper’s job is to take off leftover material called carryback. Carryback sticks to the belt after unloading. If you let this material pile up, it can cause jams and spills. It also makes the belt wear out faster. Primary scrapers work hard at this first spot. They handle tough jobs and last a long time. You can trust them to keep your system safe and running well.
There are different types of primary scrapers. Each type works best for certain materials and belts:
Blade Scrapers have a sharp edge made of metal. They scrape off tough or sticky materials.
Rubber Scrapers are softer and clean gently. They are good for belts with fine particles.
Polyurethane Scrapers are strong and flexible. They last longer than rubber and work with many materials.
T2 Blades have a special shape for extra cleaning. You use them for very stubborn material.
Tip: Choose the scraper that fits your material and belt speed. This helps you get the best results.
Primary scrapers help in many ways:
They cut down on carryback and keep the belt clean.
They stop spills, so you clean less and save time.
They make the belt last longer by stopping rough wear.
They help the belt move without jams.
They make things safer by stopping accidents from falling material.
You see these scrapers in lots of places:
Mining sites use them for coal, ore, and rocks.
Cement plants use them to clear cement dust.
Food processing lines use them to follow hygiene rules.
Recycling centers use them to stop waste from piling up.
A Conveyor Belt Scraper saves money on repairs. It also keeps your work safe and running well.
Secondary scrapers sit right after the head pulley. Sometimes, they are placed just behind it. These scrapers use a hold-down roll to press against the belt. Their main job is to clean off leftover material missed by the primary scraper. This makes the belt much cleaner. Secondary scrapers touch the belt at a negative rake angle. This angle helps them clean better. Most secondary scrapers are made from strong materials like tungsten carbide. This makes them good for tough jobs and helps them last longer.
Note: Secondary scrapers do not take the place of the primary scraper. Both work together to make the belt as clean as possible.
There are different kinds of secondary scrapers. Each kind works best for certain jobs:
Polyurethane Scrapers are flexible and resist wear. They are used for lighter materials or when you want less belt damage.
Carbide Scrapers have hard tungsten carbide blades. They are good for tough jobs and last a long time.
Tensioned Scrapers keep steady pressure on the belt. This gives you a consistent clean, even if the belt moves or changes shape.
Rotary Scrapers use spinning brushes or blades. They help remove sticky or stubborn materials.
Secondary scrapers have many good points:
They clean off leftover material and stop buildup.
They fit many conveyor systems and work with different materials.
They last a long time, even in hard jobs.
You can install and take care of them easily, which saves time.
You see these scrapers in lots of places:
Aggregate handling
Sand and gravel processing
Cement production
Fertilizer manufacturing
Port operations
Underground mining
A secondary Conveyor Belt Scraper helps your primary cleaner. It removes extra material and puts it back in the material stream. This keeps your system clean and working well.
Return belt scrapers clean the bottom of the conveyor belt. They sit at a right angle to the belt. This helps them take off material stuck underneath. You must leave enough room for the scraper to work. The scraper should be easy to reach for cleaning. If the belt is smooth, the scraper works better. Sometimes, you need to turn the scraper off or on if the belt changes direction.
Clean the underside of the belt
Need space for setup
Should be easy to reach for care
Work best with smooth belts
Tip: Look at your return belt scraper often to keep it working well.
Carryback is when stuff sticks to the belt and comes back with it. This can make a mess and hurt your system. You can use different tools to stop carryback. Primary cleaners take off most material at the head pulley. Secondary cleaners get what is left, like small bits. Using both can clean over 90% of carryback. Spray bars use water to wash away tough material. Wash boxes mix scrapers and spray bars in one unit. This setup cleans the belt and handles dirty water.
Primary cleaners use tensioners to keep the blade tight.
Secondary cleaners have strong tips to scrape off stuck stuff.
Some cleaners can bend to fit bumpy belts.
Return belt scrapers help many jobs keep belts clean and safe. You find them where leftover stuff can cause trouble.
Industry/Application | Why Use Return Belt Scrapers? |
|---|---|
Mining | Stop losing material and keep belts working |
Food Processing | Keep belts clean and stop contamination |
Wood Products Manufacturing | Take debris off belts in wood work |
You also see these scrapers in grain places and other spots that move lots of stuff. Using a Conveyor Belt Scraper here helps you avoid big cleanups and keeps things running well.
Brush scrapers have special bristles that clean the conveyor belt. The bristles can get into small spaces and take away dust and sticky stuff. Many industries use brush scrapers because they are good for hard jobs. Some brush scrapers have motors that spin the brush the other way from the belt. This helps the brush clean even better.
Here is a table that shows how each design feature helps:
Design Feature | Functionality |
|---|---|
Rubber bristles | Take off small bits and dust from hard-to-reach spots while the belt moves. |
Motorized operation | The motor spins the cleaner against the belt for better cleaning. |
Easy installation | You can put it on flat or upright surfaces without tricky parts. |
Self-cleaning assembly | The bar design makes it easy to clean and change brushes. |
Space-efficient design | It fits in small spaces where other cleaners cannot go. |
Brush scrapers are good for tough jobs like cleaning wood dust or cement dust. The rubber fingers do not wear out fast and last a long time. You will not need to fix your system as much because brush scrapers stop carryback and surprise stops. Their design works with many belt types and fits in small places.
Tip: Brush scrapers help your conveyor stay straight by taking away things that can make it move off track.
Brush scrapers are best when you need soft cleaning. You can use them for sticky or gentle materials. The bristles do not hurt the belt or what you are moving. Here is a table that shows what different bristle materials do:
Material | Properties |
|---|---|
Nylon | Strong, does not wear out fast, bends easily, and can handle chemicals. |
Polypropylene | Stiff, lets go of dirt, does not soak up water, fights chemicals, and costs less. |
Silicone | Soft, cleans gently, takes off biofilm, and does not hurt soft surfaces. |
You can use brush scrapers for these jobs:
Cleaning belts in food plants when you need gentle cleaning.
Taking off sticky things like syrup, dough, or wet clay.
Handling fine dust or powder that other scrapers miss.
Cleaning barnacles early in marine places.
Soft brushes made from nylon or polypropylene keep your belt clean without scratching it. If you clean with these brushes often, you stop buildup before it gets bad.
You need food-grade scrapers when you work with food or products that must stay clean. These scrapers use materials that do not rust or hold germs. You often see stainless steel or special plastics. Food-grade scrapers help you meet health rules. They remove food bits and stop bacteria from growing. You can clean these scrapers easily. This keeps your conveyor safe for food and other sensitive products.
Some jobs need scrapers that handle water or high heat. Water cleaning systems wash the belt with strong sprays. This keeps the belt free from sticky or wet materials. You use these systems in food plants to keep things clean and safe. High-temperature cleaners work well in places with hot materials. They do not melt or break down. You can use them with many belt types. These cleaners often work with primary scrapers to give you the best results. You get less downtime and longer belt life when you use the right cleaner for tough jobs.
Modern scrapers, like the Infinity Belt Scraper, use smart designs to solve new problems. You get magnets that pull metal chips away from the belt. This keeps your system safe from metal jams. The scraper cleans itself, so you do not need to stop the machine often. You can set the speed to match your work. This helps you remove chips fast and keeps your tools in good shape.
