Sidewall Conveyor Belt

Corrugated sidewall conveyor belt is one of the most effective ways of elevating materials. It is mainly used for materials handling at Chemical industry (fertilizer), Harbor terminal (rock / ore / coal), Power plants (coal / ash / gypsum), Crushing plants (rock / gravel / sand), Mining (ore / limestone / chemicals), Steel plants (alloys / scrap metal / iron ore), etc. Advantages:1. No Transfer Points.2. No Spillage with steep angle Conveying.3. Maximum utilisation of space.4. Minimum Maintenance, Long Belt Life.5. Wide Range of Materials can be handled.6. Low Power Requirement, Quiet Smooth Running.   QBF sidewall belting is assembled by hot vulcanization technology, which achieves super high adhesion value, flatten and non-fall off. The adhesion won’t be influenced by high temperature material.The biggest new invested sidewall belt assembly lines in China for complete belts has installed, which ensures maximum quality standards and higher productivity.  QBF has wide ranging knowledge in all aspects of sidewall conveyor belting and it's aim is to supply correctly designed sidewall belts of the highest quality.                                                                                                          Production Range:Sidewall height: 40 mm--630 mmCleat height: 35 mm--500 mmBase Belt width: 500 mm--2400 mm   Rubber Qualities:Black Standard High Abrasion ResistantBlack Oil and Fat Resistant.  Heat Resistant to 150°C   High Heat Resistant to 180°CFlame Retardant                   

Steel Cord Rubber Conveyor Belt

 Steel cord conveyor belt is extensively applied in coal, mining, port, metallurgy, power, chemical sectors for long-distance, large amount and high-speed conveying of materials.  Features:1. High tensile strength: Steel cord conveyor belt is suitable for large span, long distance transportation of materials.2. Small elongation in use: It need only a very short take-up stroke distance.3. Small diameter of drive pulley: Steel cord conveyor belt body has a layer of longitudinally arranged steel cords as its carcass, and thus is resistant to flex fatigue. Therefore, drive pulley of smaller diameter can be used to make the equipment smaller.4. High adhesion between rubber and steel cord: The steel cords are coated with zinc on their surface,and also the rubber used has the property of good adhesion with steel cords. Therefore, the rubber is tightly adhered to the steel cords and is resistant to shock and difficult to drop,so the rubber belts are long in life.5. Even tension of steel cords:Out of our advanced techniques in manufacturing, the steel cords are very evenly arranged and have the same tension, so the belts are well balanced in running and difficult to run away.6. Good troughability: As the belt body has no transverse skeleton, it is easy to from a deep trough,so the belts can load more materials and prevent the materials from escaping.7. Inspection of the belt with X-rays: Users can X-rays to inspect damages of the skeleton steel cords on the conveyor machines to prevent accidents from happening.Cover Compounds: General, Fire-resistant, Cold-resistant, Abrasion-resistant, Heat-resistant and Chemical-resistant.Standards offered: GB/T9770, DIN22131, EN ISO 15236, BS490, JIS, SANS1366 and AS1333.  Main technical index of ST series steel cord conveyor belt:GB/T9770 Standard:  DIN 22131 Standard:

Multi-Ply Fabric Conveyor Belt

 Fabric conveyor belt is a kind of traditional rubber belt, which is constructed by fabrics and covered with top and bottom rubber. It is reliable to transportation for short and medium distance, it is flexible, heavy duty and high speed. Now fabric belt is preferred to using by mining, seaport, construction, metallurgy, chemical and grain transportation. Types:Accordance with different carcass used in fabric belt, we can supply Nylon belt, EP belt. NN conveyor belt has the advantage of flexible, high tension, impact resistant characteristics, available for the conveying materials of medium distance.EP conveyor belt has the advantage of low elongation, excellent heat resistant, impact resistant, available for the materials handing of heavy duty, high speed and medium distance.  Accordance with different applications, we can produce different grades of belt as following:  1) Heat Resistant BeltAccording to the temperature of working environments, we can manufacture 3 different grades heating resistant belt, including up to 120℃ grade (HR120), up to 150℃ grade (HR150), up to 180℃ grade (HR180) and up to 200℃ grade (HR200) .Generally used by cements and steel works.2) Abrasion Resistant (≤90mm3) / super abrasion resistant (≤60mm3) BeltGenerally used for transport the hard or shaped materials, like iron ore, diamond, copper and other minerals.3) Oil Resistant BeltGenerally used for wood, papermaking, oil-based grain transportation.4) Acid/Alkali Resistant BeltAlways used in Chemical materials transportation.5) Cold Resistant BeltThe belt can work in some cold environment, like Northeast of China, Russia and North European countries.6) Fire Resistant BeltAlways used in underground coal mining, steel works and so on.7) conventional BeltGenerally used for small powder, grain and block materials.
