Introduction

AURY horizontal vibrating centrifuge (WSL series) suitable for small granularity coal drainage. Apply finite element analysis for vibrating system and key parts of WSL series centrifuge. The centrifuge quality and performance of products have reached the top level in the world.  Easy to operate and maintain, high drainage efficiency, low power consumption, few wear parts.

Characteristics

  • Apply new type structure of feed end and discharge end to ensure high handling capacity and smooth operation.
  • Apply new type structure of feed end and discharge end to ensure high handling capacity and smooth operation.
  • Apply rubber spring, new frame structure and two stage vibration to ensure high stiffness and stability.

Structure & Operating Principle_Part 1

The feed material is introduced into the centrifuge basket via a alumina tile lined feed chute.  Centrifugal force on the material within the centrifuge basket forces free moisture from the coal slurry.  The basket is vibrated along its horizontal axis which transports the dry coal along the basket towards the discharge chute where it is discharged. Water from the coal is thrown around the internal centrifuge housing and is channelled away from dry product to the water outlet where it is discharged from the centrifuge.

Structure & Operating Principle_Part 2

The basket in the WSL centrifuge is driven via a heavy duty motor and Vbelt pulley arrangement.  A flexible coupling allows vibration of the basket without effecting the drive shaft and bearings. Screen basket vibration is effected via a pair of vibrating motors.  These motors are configured on a tuned mass so as to create significant horizontal vibration of the basket and only small vibration within the centrifuge main structure, thereby minimizing dynamic loading into the support structure.

Introduction

AURY ML series centrifuge suitable for 0.15-3mm small granularity coal drainage. Easy to operate and maintain, high drainage efficiency and Brief structure.

Characteristics

  • Apply new type structure of feed end and discharge end to ensure high handling capacity and smooth operation.
  • Apply rubber spring, new frame structure and two stage vibration to ensure high stiffness and stability.
  • Apply mechanical and electrical integration control system, easy to operation and maintenance.

Structure & Operating Principle_Part 1

The AURY ML series fine coal centrifuge is a horizontal design with a rotating scroll within the centrifuge basket.  Feed slurry is fed into the rotating basket via a tile lined feed chute. Centrifugal forces within the rotating basket dewaters the fine coal slurry, while the scroll which rotates at a slower speed within the basket scrapes the dewatered fine coal from the basket and into the discharge port of the centrifuge. Water from the coal is thrown around the internal centrifuge housing and is channelled away from dry product to the water outlet where it is discharged from the centrifuge.

Structure & Operating Principle_Part 2

The basket in the WSL centrifuge is driven via a heavy duty motor and Vbelt pulley arrangement. A flexible coupling allows vibration of the basket without effecting the drive shaft and bearings. Screen basket vibration is effected via a pair of vibrating motors.

These motors are configured on a tuned mass so as to create significant horizontal vibration of the basket and only small vibration within the centrifuge main structure, thereby minimizing dynamic loading into the support structure.

A) Fixed part

Fixed part include base support, supporting seat, transmission seat, shaft seat, Centrifuge body, cushion device and Lubrication device. lShaft seat, Shaft seat of hollow shaft which is fixed on transmission seat.

B) Rotation part

The main centrifuge drive motor drives the Input  shaft and hollow shaft transmission through differential gearing, resulting in high-speed rotation of the centrifuge screen basket, and providing a differential in rotating speed of the scroll.

C) Screen basket

Stainless steel slotted screen basket is assembled on bracket which is on the hollow shaft.

D) Lubrication System

The lubrication system which locate in one side of centrifuge.Lubrication oil is stocked in oil tank which is pumped through a strong magnetic filter, then via a fine conventional oil filter, through an oil flow meter to the internal centrifuge bearings. Oil then flows back to the oil holding tank to again be recycled through the machine. Use dipstick to measure oil lever after machine stop for half an hour. There is pressure switch in lubrication System to ensure enough lubrication oil flows.

E) Electronic control equipment

Rotation motor and lubrication motor are T.E.F.C type

F )Overload clutch

Overload clutch use for protection of scraper blade. The main motor will be stopped when machine overload.
