They are strips of continuous movement that are used to transport different materials from one place to another. It is mainly used to transport large quantities of material in a short time. Conveyor belts are also called belts conveyor. Industrial conveyor belt systems. Industrial conveyor belt systems consist of two or more pulleys. A continuous transport flow circuit of the conveyor belt revolves around the conveyor belt. To move the belt and the material to transport one or both pulleys, it must be fed. Industrial conveyor belt systems. These belts are usually made of rubber, PVC, urethane, neoprene, nylon, polyester, leather, etc. Industrial conveyor belts consist of several layers of material. Most of the material transfer belt consists of two layers. The lower layer is known as the body and gives it a linear strength and shape. The body consists of polyester, nylon and cotton. The top layer is called cover. Various rubber or plastic compounds are used to make the cover. Conveyor belts used for industrial use: Almost all manufacturers and suppliers rely heavily on labor before the appearance of industrial conveyor belts. Workforce safety and product quality are important issues when handling the product manually. In the current industry-driven scenarios, these pulleys and rotating belts are selected for product processing. Conveyor belts used for industrial use: Today, sophisticated technology is used for industrial conveyor belts through simple conveyor belt systems. High quality belts are selected according to the specific application of the industry. For example, a simple metal belt cannot process stone, which can be a valuable or sensitive material. The material handling industry fully understands the types of conveyor belts. Depending on the application, we choose a conveyor belt system that is safer, less slow and more efficient than your requirements. The most used industrial conveyor belts and their applications: Roller Bed Conveyor Belt The surface of a roller bed conveyor belt is a set of rollers that match the weight and speed required by the product. The length of the roller bed conveyor belt determines the number of rollers to be used. A roller bed conveyor belt is designed for applications where materials are loaded by gravity. They are an ideal solution for conditions where materials have to be moved over long distances since they are designed to reduce friction. Flat Belt Conveyor Belt A flat belt conveyor belt uses a series of pulleys to move materials and supplies. Its belt is made of natural or synthetic materials; this makes it versatile and adaptable to varying conditions and applications. In some instances, a flat belt conveyor belt may have a center drive and nose bars. Modular Conveyor Belt A modular belt conveyor consists of interlocked pieces made of hard plastic with segments that can be easily removed and replaced. The design of modular belt conveyors makes it easier to clean, and the material is resistant to sharp and abrasive substances. Modular belt conveyors come in varying configurations and use a single belt to go around corners, in a straight line, up inclines, and down declines. Cleated Conveyor Belt Cleated belt conveyors have sections, pockets, or dividers that secure granular products when the belt declines or inclines. The cleats have equal spacing between them and come in various styles and shapes depending on the product to be moved and the design of the belt. Inverted Capital T An inverted T cleat stands perpendicular to the belt and provides support for delicate and fragile materials. Forward Leaning Capital L A leaning capital L has a wide base that can be curved to scoop up granular materials. The design of the capital L makes it less resistant to leverage forces. Inverted V Inverted V cleats are two inches or less to create a trough like effect and are used for heavy, abrasive, and larger pieces of bulk materials. Lugs and Pegs Lugs and pegs are designed to meet the specific needs of a product and are a cost-effective solution for products that do not require continuous support, such as cartons. They can be selectively placed to move products of varying sizes. Sidewall The purpose of sidewalls on a conveyor belt is to keep the material being moved on the belt. Sidewall conveyor belts are ideal for incline and decline belts and help increase product load capacity to improve conveyor system efficiency. There are a wide variety of sidewall materials, and they can be corrugated at various depths to fit the needs of the product and application. Curved Conveyor Belt The curves in conveyor belts are used to carry products around corners, make transfers, and make efficient use of floor space. Curved conveyor belts can make "U" turns to face the direction from which they came. They are made with flat belts and can make turns at 45o, 90o, 135o, and 180o angles. Incline Conveyor Belt Incline conveyor belts have a rough, uneven surface to hold materials and prevent them from slipping or falling back. The underside of the belt is smooth to allow the belt to glide smoothly along the bed. Modular belt and timing belt conveyors can be used for this purpose. Depending on the material to be moved, cleats may be included for increased slippage prevention. Decline Conveyor Belt The purpose of a decline conveyor belt is to move products or materials down or change its height. As with the incline version of conveyor belts, a decline conveyor belt has a rough surface or cleats to prevent materials from slipping or falling. Decline conveyor belts are a continuous operating conveyor system with an articulated frame with a section that is pivoted or placed downward to accommodate downward movement of products from an upper location. An advancement in conveyor belt technology is the Electro adhesion conveyor belt, which acts like a magnet that is activated by a switch to create a strong and secure holding force between the container and the belt. Two low amp power strips placed in the conveyor belt powers its holding force. Materials with an electrically conductive pattern are knitted into the belt to produce the force that holds materials in place. Filter Conveyor Belt Unlike conventional conveyor belts, filter conveyor belts allow materials to pass through in order to drain excess liquid from components or filter out toxins and contaminants. Filter conveyor belts are constructed with lateral grooves and holes in the center of the belt to allow liquids and fluids to escape. Drainage holes are placed in a fabric free zone down the center of the belt or sealed to prevent the liquid from soaking into the belt fabric. Much like a sidewall conveyor belt, filter conveyor belts can have sidewalls to prevent liquids and fluids from spilling over the sides of the belt. They are made of heated polyester, polypropylene, polyolefin, or stainless-steel mesh for dewatering applications. Vacuum filter belts are used for washing coal and other ores to assist in the separation of fluids and solids. Hinged Conveyor Belt Hinged conveyor belts are made of joined flat metal slats designed to rotate around pulleys. The slats are interlocked to form a continuous metal belt that is durable and able to withstand harsh, stressful, and rigorous conditions. Hinged conveyor belts are used to move steel chips, turnings, metal parts, and discharges from presses and are configured and designed to fit a specific application. Piano hinged conveyor belts are designed to eliminate the negative effects that handling steel can have on a standard belted conveyor. They are used to remove steel punching’s and scrap from presses as well as for transporting hot and cold formed castings. Piano hinged conveyor belts are made of cold rolled steel and can be used for flat or inclined conveying applications. Indexing Conveyor Belt An indexing conveyor belt moves a product a set distance in a step-by-step fashion using fixtures to hold the product in place. The process of indexing is designed to move incomplete components through a set of positions easily and precisely and is normally part of a machining process. Indexing conveyor belts are used in production applications during assembly operations to move a workpiece from station to station. Sandwich Conveyor Belt A sandwich belt conveyor has two belts that are face to face with one belt on top of the other to firmly hold materials. They have a rotating wheel for adjusting the pressure and gap between the belts. Anti-Static Conveyor Belt Electrostatic charge on a conveyor belt can be created by friction between the belt and the bed, the movement of the conveyed product, or ionization in the air. In most cases, the static current is of low intensity but can cause problems if materials stick to the belt. Though the charge is very low, it may cause sparks, which can lead to serious and hazardous conditions. There are various devices that can be installed on conveyor belt systems that dissipate and eliminate static charges. Anti-static belts are also available that are made of materials that have no-carbon particles and are made of fabricates that are static dissipative.
