Inclined screw is one of the types of screw elevators that is responsible for transporting materials. Crushed or inclined or lifting pipe screw conveyor, spirals are stretched around a pipe and then rotated through a gearbox. Due to the rotation of the tubular screw, materials such as cement, flour and other materials are transferred from the side of the inlet pipe to the side of the outlet pipe.
Important features in the design and construction of the inclined screw conveyor or tube. This device is also used to transfer cement from the silo and from the silo to the scale and from the scale to the hopper or mixer. As a lifter, the tubular screw changes at different angles between 0 and 70 degrees.
This lifting device with a tubular structure has the ability to transfer materials with a relatively high density. This feature is due to its spiral.
Inclined screw conveyors usually operate slightly above the horizontal position up to 45 degrees from the horizontal position. A screw conveyor inclined above 45 degrees is considered. As the degree of slope increases, the transmission efficiency decreases. Also, due to the effect of gravity and bulk materials, there is a need to increase the power of the electric motor.
Important features in the design and construction of this device
Slope up to 10 degrees
The loss of efficiency in the transmission of slopes above 10 degrees. U-screw and full-screw inclined screw conveyors are sufficient for most applications. By increasing the speed of the blade, increasing the diameter of the blade or reducing the screw of the blade, the loss of efficiency can be solved.
Slope between 10 and 20 degrees
The manufacturer of inclined or tubular screw conveyor Saman Farazaz loses efficiency in transmission, usually between 10 and 40 percent at slopes of up to 20 degrees. U-bolt and 2/3-screw conveyors are sufficient for most applications. Loss of efficiency can also be overcome by increasing the speed or diameter of the screw conveyor. An increase in the power of the electric motor is required to overcome the gravity and fall of the bulk material.
Slope between 20 and 30 degrees
Transmission efficiency loss is typically between 10% and 70% at slopes up to 30°. A mortise or screw with a tubular housing and reduced screw pitch (1/2 or 2/3) is recommended for most applications. The loss of efficiency can also be overcome by increasing the speed or diameter of the screw conveyor. Increased strength is required to overcome gravity and bulk material fall.
Slope between 30 and 45 degrees
Transmission efficiency loss is typically between 30% and 90% at slopes up to 45°. A screw conveyor with a tubular housing and reduced screw pitch (1/2 or 2/3) and larger diameter is recommended for most applications. It is also necessary to increase the speed of Mardon. Additional horsepower is required to overcome gravity and bulk material fall.
