Coal mine fixed belt conveyor is generally applied to the fixed convey of main roadway, main lane or main slant, and its major features are long haul distance and large volume. It usually adopts steel landing to fix fuselage (when the haul distance is less than 500 meters and the volume is small, can use the cord rack to hang the fuselage). Long haul distance and large volume of the belt conveyor, with multiple advanced technical, like multi-driving, controllable soft starting, and multi machine power automatic balance, its driving element adopts variable speed fluid couplings with orthogonal cone cylindrical gear reducer or orthogonal shaft planetary reducer; the automatic tightener keeps the constant tension of the conveyor belt; it equips with microcomputer control to realize the automatic tension of the belt conveyor, the multi machines detection and correction of the balance and operation status. The performance of the whole machine is stable, reliable, and high automation.

Big obliquity belt conveyor adopts flat belt conveyor with deep groove roller set and soft starter device to achieve big obliquity transportation and the max upwards dip angle is up to +25 ; according to the specific circumstances, downwards belt conveyor sets damping device, motor feedback braking, or special damping brake, adjustable braking torque hydraulic disc brakes and special damping facility, and its max downwards dip angle is up to 18; the soft starter device can ensure that the control speed is automatically adjusted at startup, and the acceleration maintain between 0.1 and 0.3m / s2. The driving device is equipped with hydraulic push brake and NF backstop to ensure the safety of the belt conveyor and prevent reverse. Load carrier roller set is a deep grooved roller set composed of four or five supporting rollers; the conveyor belt adopts flaming retardant steel core belt and is provided with various safety protection to ensure the normal operation of the conveyer.

Remarks: 1DTC type is a big obliquity coal mine fixed belt conveyor.

                2Only part of the technical specifications of the landing structure of rigid frame of the coal mine fixed belt conveyor are listed in the table, and the conveyor with the steel frame suspension structure is basically same, but the lower limit of the volume and speed should be selected.
