Convoyeur horizontal

Horizontal Conveyor

Fully sealed to limit odours and leaks, they are designed to transport more than 60 m³/hour of sticky, slimy, stringy materials and all types of materials likely to clog and/or form keystones.

Up to 45 meters in length for a single conveyor, the absence of ball bearings at the end allows direct connections when the path of the materials transported requires several conveyors in series, whether horizontal, inclined or vertical.

The maintenance of these conveyors is very simple and their use is particularly economical.

CASE STUDY: SCREENING DISCHARGE CONVEYOR

A screening reject conveyor receives the rejects from two screens. The conveyor transports the rejects to a washer-compactor. The washer-compactor filters the organic matter and then compacts and spins the rejects.

  • Conveyor capacity: 4 m³/h of discharge

  • Trough filling rate: 37%

  • Screw rotation speed: 15 rpm

Safety devices: 1 rotation detector, 1 emergency stop cable, 1 circuit breaker.

Inclined Conveyor

Inclined coreless screw conveyors are used to transport materials at up to 45° inclination.

CASE STUDY: INCLINED CONVEYOR FOR CENTRIFUGAL SLUDGE

The inclined conveyor receives the sludge from a centrifuge, transports it and raises it to transfer it to an elevated conveyor intended to load a truck by 4 outlet chutes. 3 outlet chutes are equipped with guillotine valves allowing uniform filling of the truck bin located under the unloading conveyor

  • Conveyor capacity: 10.19 m3/h

  • Trough filling rate: 50%

  • Screw rotation speed: 20 rpm

  • Conveyor inclination angle: 40°

The gear motor is installed at the top of the inclined conveyor while a 6-inch drain is welded onto the bottom end plate of the conveyor.

Safety device: 1 rotation detector, 1 circuit breaker

convoyeur incliné

Vertical conveyor

Vertical coreless screw conveyors are used to transport materials that cannot be pumped. Atara™ is proud to have installed in 2002 the highest vertical conveyor in the world for the extraction of 10 m3/hour of sand and vertical transport over 21 meters. This installation is still in operation.

CASE STUDY: VERTICAL CONVEYOR FOR CENTRIFUGAL SLUDGE

The vertical conveyor receives the sludge from a centrifuge, which it transports vertically to transfer it axially into a recovery conveyor. The recovery conveyor then transfers the sludge into a horizontal truck loading conveyor via two outlet chutes equipped with guillotine valves. The loading conveyor is designed to load a truck via 4 outlet chutes. 3 outlet chutes are equipped with guillotine valves allowing uniform filling of the truck bin located under the loading conveyor, the last chute being open at all times.

This system includes 4 horizontal conveyors and one vertical conveyor

  • Conveyor capacity: 4.7 m3/h

  • Vertical trough filling rate: 100%

  • Screw rotation speed: 15 to 20 revolutions/minute

Safety device: 5 rotation detectors, 4 emergency stop cables, 5 circuit breakers

convoyeur vertical

Leveling conveyor

Installed above skips, hoppers or truck trailers, they optimize their filling with or without guillotine valves.

CASE STUDY: TRUCK LOADING

This unloading system consists of a cross conveyor feeding two unloading conveyors.

The cross conveyor receives by gravity the sludge from two centrifuges operating on the upper floor. It then transfers the sludge to one or the other of the discharge conveyors. These two conveyors discharge the sludge through their five outlet chutes, four of which are equipped with guillotine valves.

Level sensors are designed to detect the presence of a trailer. When the presence of a trailer is detected, the sensors send a signal to start loading the slurry. Once the sensor of the last chute detects that the pre-set maximum loading level has been reached, a new signal stops the system or transfers the excess slurry to the other conveyor. The full trailer can be replaced by a new empty one.

· Conveyor capacity: 12m³/h

· Trough filling rate: 45%

· Screw rotation speed: 21 - 23 rpm

Safety devices: 3 rotation detectors, 3 circuit breakers and 10 level sensors

Guillotine valve

With their ultra-robust design, Atara™ knife gate valves combine simplicity and efficiency. 100% leak-proof when the application requires it, the Atara™ knife gate valve range combines perfectly with all types of screw conveyors, both for conveyors manufactured by Atara™ and by others. They can be operated manually, pneumatically or electrically.
