Types of Belt Conveyor Take-Ups. Various take-up configurations each offer distinct advantages and disadvantages. Common types of belt conveyor take-ups include the gravity take-up, screw take-up, and horizontal take-up. Screw Take-Up. The screw take-up configuration uses mechanical force to take up all the slack in the belt.

A conveyor belt is the carrying medium of a belt conveyor system (often shortened to belt conveyor). A belt conveyor system is one of many types of conveyor. All conveyor system needs Safety Switches or Devices to protect the system. Some of Safety Switches or Devices are called as below ;
Spiral Wing Belt Conveyor pulley . Spiral wing belt conveyor is a kind of efficient conveying equipment, which is widely used in the metallurgy, petrochemical, chemical industries, etc. The working principle of spiral wing belt conveyor is that the material on the top of the belt will be moved towards to the bottom by rotating spiral wings.
The coal washing plant, which we also name as coal preparation plant, is to clean coal and remove out coal gangue. The coal conveyor is a very important equipment to process raw coal. The coal conveyors are mainly used to link coal washing machines and stockpile coal into stockyard, silo, bunker, etc. Coal Port Belt Conveyor
all other spragging devices have been removed; the take-up system is operational. 5. CONVEYOR SYSTEM PROTECTION DEVICES The belt conveyor shall be provided with various devices and systems for protecting the system. These devices are used as run-permissive input commands to the general belt control system. The devices must be seen
consignment to be selected for inclusion in the sample. The sampling standards also agree that the best way to collect sample increments is by stopping the moving conveyor under load and taking full cross-sections by collecting all the material (lumps and fines) between two parallel planes (see Figure 2).
