Put in simple terms, conveyors are vertical, horizontal, or inclined elevators that help in transporting different materials from one place to another. Conveyors play an important role in industries where in heavy materials need to be transported in bulk within different factory units. In automotive, pharmaceutical, food, and manufacturing industries, the conveyors are used for multiple purposes. The performance of these conveyors is directly linked with the quality and efficiency of the factory output. Because a failure in a conveyor may result in partial or complete halt in the product manufacturing, the maintenance and repair planning are crucial parameters in any factory set-up.
There are various conveyors available in the market—mechanical and non-mechanical—these are widely used in the various industries. Chain conveyors make use of multiple chains that when runs on a motor pull the loaded material along with them as friction is generated between the chain and the material. Screw conveyors make use of screw-like blade that when runs, moves the liquid or granular material with it. Another often seen conveyor, the vertical conveyor, is widely used in many factories to lift heavy materials. Here we will discuss about two other popular conveyors designs that are seen in numerous instances.
A belt conveyor consists of a belt and at least two pulleys. The belt rolls over the pulleys out of which one pulley is powered by a motor. The belt conveyors have been used since the 19th century for different applications. The belt has the inner material and a cover—the outer layer. The belt is made from materials like polyester to provide shape and resistance to the belt, whereas the outer layer, the cover is usually made from rubber or plastic compounds. Depending on a belt conveyor design, different types of belts and frames that hold the belts are used.
These conveyors designs can be used both in bulk material transport and general piece by piece transport. For example, in an agriculture industry, grains and other agricultural produce is loaded on the belt. In shopping stores or baggage handling units, conveyor belts are frequently used. While on the belt, the material is weighed by the belt weighing system. These belt weighing systems can also be equipped in reporting material slippage or belt stoppage. Various scales and control systems are attached to these belts weighing system.
These are not limit on how long these belts can run and we have some real-world examples of conveyor belts that run many kilometers long. In a particular conveyor design, the safety system is an essential part of the belt conveyor. These are simple conveyors and these can easily fit in various plant designs. The inclination angle and temperature resistance are two of the non-avoidable constraints of these conveyors.
Unlike belts or chains, pneumatic conveyors are made of ducts, pipes, or tubes that are concealed. A material transported using this kind of a system is always in a powdery form. When powdered, fruits, chemicals, dairy, or minerals can be transported through these conveyors. There are two commonly used types of conveyors—a suction type and a pressure type. In a suction type conveyor, the suction system is fitted at various points to suck the material towards the destination, whereas the pressure type conveyor uses the pressure systems to push the material towards the other end. Some rare conveyor designs make use of both these systems in combination. When compared with to the belt conveyors, these conveyors are more flexible as the tubes can be bent to fit the requirement. They are also less likely to get dirty as enclosed all the time.
However, their usage is limited to transportation of certain materials. They also require greater horsepower to operate. If you still want to know more then let’s go here and get more information about conveyor design.
