AW Process Specialist In The Cement Industry

---

 AW Process is the Manufactures Rep.  for DCL in Florida and the Caribbean. DCL manufactured Loading Spouts lead the way in innovative use of technological advancements to provide dust-free loading of a wide range of dry, dusty materials, at loading rates up to 6,000 STPH. 

Aeration conveyors (Air Slides) are used to gravity-convey powders by passing low-pressure air through a porous membrane media and into the bed of the material being handled.

You can handle a large variety of materials with aeration conveyors regardless of their abrasive nature or bulk density. The criteria are particle size, moisture content and temperature. Generally a product should have a particle distribution of 100% through a 20 mesh screen. Moisture content should be below 1% and temperature can not exceed 1200 degrees Fahrenheit [649˚ C].

The absence of moving parts and low power requirements make air gravity conveying the most economical way to convey fine materials over short or long distances.

Reliability in operation, high conveying capacities, long lifetimes and low running costs are what make bucket elevators from AUMUND stand out. Bucket elevators can be designed with either a forged central chain or a belt, depending on the material to be conveyed and the application.

Aumund Chain Bucket Elevator are equipped with a forged central chain and are designed to convey all kinds of coarse, hot or abrasive bulk materials. Even operating 24/7, they can convey over 900 m3/h at centre distances of over 30 m.

• conveying of bulk materials with temperatures up to 850°C
• heat resistant up to 400°C
• homogenous material flow with minimal spillage due to closely arranged buckets
• easy, reliable fixing of buckets to chain maximises lifetime (AUMUND patent)
• forged chains with lubricated labyrinth seal
• silo and mill feed applications
• suitable for abrasive, hot, coarse and fine materials

AUMUND developed the BWD Double Bucket Elevator as a means for tackling conveying capacities of over 1,800 m3/h. This bucket elevator can be designed with centre distances of over 90 m and is a combination of two standard bucket elevators, each with a rear central chain. Both bucket strands run on a common drive shaft which is supported in plummer block bearings and driven by double drives. 

• conveying capacities of more than 1,800 m3/h
• centre distances greater than 90 m
• symmetrical weight distribution for long service life of chain and drive shaft
• no mechanical connection between the bucket strands
• material feed via flow divider
• tension axles are supported separately in order to be able to control the chain length of the two strands independently of each other

Automated production processes often require stockpiling or blending of raw materials, additives and intermediates. Bottlenecks in material flow to or from hoppers, storage halls, stockpiles or silos can hinder plant productivity, therefore the right design of the conveying and storage technology is paramount.   

AUMUND proposes a range of pan conveyors specifically tailored to individual applications and to the characteristics of the material to be transported:

• BPB Arched Plate Conveyor
  
• KZB Pan Conveyor
  
• BZB Bucket Apron Conveyor
  
• FPB Flat Plate Conveyor
  
• SPB Pivoting Pan Conveyor
• DPB Apron Weigh Feeder

 The Samson® Material Feeder from AUMUND is a discharge conveyor which receives bulk materials directly from trucks or other vehicles and unloads rail wagons or front-end loaders. A flexible solution, it is chosen in many industries and applications all over the world for its technical benefits and its cost-effectiveness 

• controlled rate discharge of bulk materials from trucks, wagons etc.
• ideal for materials handling in combination with front-end loaders
• handles materials that are dry and dusty, heavy, wet or sticky
• no bridging or blocking of material
  
• no more underground hoppers or deep pits required
• dust is minimal due to the controlled rate discharge and low falling height
  
• can be used in a great variety of applications

Chain conveyors are generally used where sticky bulk materials such as chalk, gypsum, clay or raw coal are to be extracted from a hopper. For such applications AUMUND recommends the PKF armoured chain conveyor.

For extraction of filter dust or additives the AUMUND TKF Drag Chain Conveyor Type LOUISE is often used. As this machine conveys bulk material in a closed trough, the impact on the environmental is minimised.
