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 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 punchings 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. 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. 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. 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. As essential as conveyor belts are to the efficiency of various industrial operations, it is easy to summarize their operation. In essence, a conveyor belt is a very large wide belt that is similar to a huge rubber band affixed to rollers in the shape of a loop connected to rotors powered by a motor.
The loop in the design is the conveyor belt, which is made of various types of sturdy and durable materials. The motor on a conveyor belt turns the rotors that move the conveyor belt.
There is a sufficient amount of friction between the belt and the rotor for the belt to stick to the rotor. The turning motion of the rotors causes one side of the belt to move in one direction, while the other side moves in the opposite direction.
The different motions produce the movement of the conveyor belt. Pulleys are positioned at either end of the conveyor belt or near the drive motor. The drive pulley drives the conveyor belt and has external bearings that are driven by a motor and reducer. Pulleys can be flat faced or crowned and have lagging to reduce belt slippage. Return or tail pulleys redirect the conveyor belt back to the drive pulley, have internal bearings, and are located at the end of the conveyor bed.
The purpose of tail pulleys is to provide tension in the conveyor belt. Rollers support the materials on the conveyor belt as they move along the belt and support the belt during its return. The center of the shaft of a roller has a spring retained axle that is used to install and remove it. The position and location of the rollers reduces the amount of power required by the motor to move the conveyor belt. There is an endless number of types, sizes, shapes, angles, and materials for conveyor belts.
In a conveying system, the design and type of conveyor belt determine how it functions, and it is fabricated to carry materials and products from one location to another. However, many conveyor systems rely on a frame with a belt and possible support rollers to carry materials and products efficiently. All conveyor systems have three main components — the aluminum profile, the driving unit and the extremity unit. In a conveyor belt system, the aluminum profile consists of the frame, belt and any supports.
Systems that use a belt are generally powered by a motor, though conveyor systems can also use gravity or manual force to function. Motorized conveyor belts are ideal for industrial use as they are more reliable and efficient — the driving unit for such systems would include the motor bracket, electrical drive and any counter bearings.
Parts and functions of a new conveyor belt system might include:. Conveyor belting can be crafted from various materials, including rubber, metal, leather, fabric and plastic. Consider the conditions that your system will operate under to ensure the conveyor belting material is of suitable thickness and strength. How is a conveyor belt typically used?
The conveyor belt pace, direction, curvature and size varies based on the needs of the user. In some industries, a conveyor belt brings products through a manufacturing or packaging line and back out again. As stated, conveyor belts are integral to the operations of a wide variety of industries, therefore, are able to offer multiple benefits.

When did a conveyor belt get invented? Modern Conveyor Belts As we entered the s, which is acknowledged to be the contemporary period for these systems. The Fundamentals Belt conveyors consist of a drive roller powered by a drive motor with a tension roller at the opposite end moving an endless loop of the conveyor belt which rotates around them.
What are conveyor belts used for in industries today? This rotor or wheel allows the belt to navigate along the bend without getting twisted. Belt conveyor systems manufacturers design two primary types of systems. These include belt systems for general material handling and belts for bulk material handling. A conveyor belt system makes material transportation easier, faster, safer, and efficient.
Well-designed conveyors take the load off of material handling across production lines. Processes using materials that may be too bulky for people can benefit from conveyor systems. Manual handling can result in time consumption, material damages, physical strain, and even injuries.
By automating material movement, a conveyor system saves time and resources for businesses. An inclined conveyor serves the best in processes where materials need to be moved across floors or across multiple levels on the same floor.
It simplifies and speeds up the task of moving materials up and down. The efficiency of conveyor belt systems in handling a wide range of business materials, from raw goods to heavy end-products such as vehicles, makes them a great asset for businesses.
