Working principle of belt conveyor
The working principle is the conveyor belt transports the material that is on the belt, where the feed or inlet on the side of the tail using a chute, and after arriving in the head material spilled as a result of belt-turn. Belt driven by the drive / head pulley using a motor. Head pulley belt pull with the principle of friction between the surface of the drum with the belt, so that the capacity depends on the frictional force.Belt conveyor proven capable of transporting material varying from large, heavy, sharp bumps, fine particles, wet, sticky, mud, powder, sand, potato chips, wood logs, wood chips, and others.
Of all the material handling system, belt conveyor operates at a lower cost, low-power, low maintenance costs, low power, and a little labor.
Function conveyor belt
Conveyor belt function is to transport / transport material from one place to another (hooper and bulk storage)Conveyor belt system consists of six main parts:
- Belt, no moving parts to transport the material
- Support systems, strut round the conveyor belt
- Pulley-pulley, drive belt lap and voltage controller
- Drive unit, the driving force is transferred to the belt
- Frame, steel construction which supports the whole fabric belt system
- Chute, a material loading and shed
Main elements of belt conveyors
Other additional components that are used for operational maximize belt conveyor system are:
- Ballast (take-up or counter weight), or so-called gravity pulley function is to regulate the voltage and prevent belt slippage at the driving pulley for growing longer belt
- Tripper, is the part that serves to regulate the spill material so they are flush, use the belt in bulk storage
- Belt cleaner, serves to clean the belt from dirt falls into the inner side and bottom of the material on the belt after the spill
- Skirtboard, serves to retaining material on the spill to keep it out of the chute in the belt
- Holdback, function to prevent the belt so as not rotating opposite if the current belt or die suddenly stopped
- Emergency stop, to stop the belt spontaneously
- The vacuum cleaner to suck the dust flying around belt caused by dust material
- Roof and wall protectors, used on an open area so that the material is not damaged.
Specifications conveyor belt
The strength of the conveyor belt is not seen from the thickness, but seen from the number of ply (amplifier). In general, the construction of belt conveyor consists of three main components:
- Cover Rubber
Cover rubber is a synthetic rubber coating that has a high elasticity and abrasion resistant. Cover rubber layer serves to protect the amplifier from a bulker, friction and impact of materials at the time of loading in order to ply not damaged. Cover rubber consists of top cover and buttom cover - Tie Rubber
Tie Rubber is rubber layer between the ply. Tie Tie rubber is also often called atu Skim rubber gum. Tie rubber ply serves to attach to one another on the fabric belt - Reinforcement - Layers amplifier (Ply)
Reinforcement is a layer of reinforcement for conveyor belt itself. Force or tension on the belt reinforcing layer used depends. In general, the reinforcing layer is made of fibers (caracas) and steel cord.
