What is Scraper Chains?
It is a type of chain with flights that are scraping the material over the bottom of the casing. The material is moving forward to the discharge point.
Scraper conveyor chains products generally use a single or double strand of chain. Flights are either welded directly onto the chain, or bolted onto the chains attachments.
Scraper chains have a wide range of uses such as moving feed, ash, cement, wood shavings, slags etc, or scraping settlement tanks (either above or below the water lines)
Scraper-flight conveyor chains are chains used in various fields such as iron, steel, coal and mining industry, grain silos, sand quarries, feed, pasta, flour industry, in order to carry the load to be carried over long distances by sweeping method. It generally works by attaching UHMW (PE1000 / PE500 / PE300) or POM (DELRİN) material to the scraper flights of the chain.
Scraper chains transfer granular or aggregate product at full rate over a distance that may include a level change while protecting the transported material from the weather. In conveyors, they can be used for cooling or dehydrating product during transfer (through air or water circulation), mixing and measuring, bulk handling for storage, process supplying, extracting, distributing at several points, picking up product, and lifting decanted or washed product.
What are Scraper Chains used for?
Scraper chains are used in various fields such as iron and steel, coal and mining industry, grain silos, sand quarries, feed, pasta, flour industry in order to carry the load to be transported over long distances by sweeping method. It usually works by connecting PE1000 material to the scraper ears of the chain.
In order for industrial machines to operate efficiently and effectively, the components used must be of high quality and functional. Among the components, especially the functionality of scraper ear chains is of critical importance for industry and production facilities.
Scraper chains are an important element of material transportation and movement in industrial production processes. It is especially preferred due to its durability and performance in harsh working conditions. fv din 8165 and m din 8167 standards show that the design, production and quality control processes of the chain are internationally recognized.
What are the Usage Areas of Scraper Chains?
Scraper chains are used in many different fields in the industry. Scraper chains are used in the mining industry, agriculture and food industries, and construction industry. In the mining sector, it is used in underground conveyor systems for heavy material transportation. It offers high efficiency to its users in the transportation and processing of grain, vegetables and other food materials. Scraper ear chains are also used in automotive and heavy machinery production. In these sectors, it is effective in parts transportation and assembly lines. It is used in many different areas such as chemical processing plants, paper and cellulose production lines and waste management.
What are the Advantages of Scraper Chains?
Scraper chain conveyor is ideal for carrying bulk non-abrasive materials, horizontally or up a small incline, these conveyors feature a closed box.The chains scrape the floor of the box and return on guide rails at the top of the box.With a single chain, scraper flights of integral malleable steel or in the form of L attachments protrude on each side to span the box. With two strands of chain, the scraper flight is carried between strands.
Chains and accessories are used in scraper conveyors for ash removal system of thermal power plants which are required to operate continuously. Due to constant abrasion of these chain links against each other as well as due to the abrasive material which is being handled in the ash removal system, surface treated chains are essential to give a reasonable service life and to work without frequent replacement.
Scraper Chains Production
Scraper chains are widely used in metallurgy, building materials, electric power, chemical, cement, coal, port, mine, food, feed and other industries and sectors. Chain scraper conveyor is an enclosed machine to transport bulk materials continuously under the help of the moving chain; due to the transportation of materials, these chains are all buried in the material, so it is also known as the scraper conveyor.
The cement scraper conveyor chains are featured by it’s simple structure, good sealing performance, convenient installation and maintenance, and flexible process layout; it not only can be designed for horizontal conveying but can also be inclined or vertical conveying; Because the conveyor casing is enclosed, therefore when conveyor transports large, toxic, explosive, high-temperature materials, the working environment can be improved and the environmental pollution can be controlled significantly.
- Ideal for fuel transport & fuel distribution
- Efficient storage room utilization
- Can be individually planned on existing floor plans
- Dust protected due to full covering
- Low maintenance effort due to easily replaceable wear parts
- Simple and robust construction
- Economic operation due to the use of efficient drive elements
- Low cost due to long-lasting structure, which makes them cheap scraper conveyor chains
Reliable transport of:
- Wood chips
- Pellets
- Sawdust, and bark as accompanying material
- Waste wood
- Special fuels (for instance: corncobs, cherry stones, chicken litter)
- Ash
These conveyor chains are useable as:
- Fuel transporter over longer distances up to 30 meters
- Fuel transporter to a higher level
- Fuel distributor for cascade systems
- Central ash discharge
Chain scraper system is chains used in various fields such as iron, steel, coal and mining industry, grain silos, sand quarries, feed, pasta, flour industry, in order to carry the load to be carried over long distances by the sweeping method.

Scraper conveyors are high-performance conveying machines for the horizontal and ascending transport of very different materials.
This conveyor is a material transportation device utilizing a continuous, driven chain circuit equipped with regularly spaced cross members. The chain travels through an channel or trough which prevents the transported materials from falling off the conveyor while the cross members drag or “scrape” them forward to the discharge point. These conveyors are typically used for coarse, heavy materials such as raw coal, iron ore, cast metal parts, and metal scrap. The design is ideal for slower transportation speeds over short distances, on moderate inclines, or even in submerged applications. This type of conveyor is typically more cost effective to install and maintain than a belt conveyor of similar capacity and length.
The primary purpose of the scraper is to prevent material carry back on the conveyor system. By reducing material carry back, the conveyors can run more efficiently by having fewer breakdowns and lower running costs. Efficient and correctly adjusted scrapers save the plant operator time and money.
