Pneumo-Drier pneumatic conveying systems that work
The BATEMAN Pneumo-Drier dries a particulate solid while conveying it. This is achieved simply by
introducing the wet particulate material into a pneumatic-conveying system driven by heated air.

The BATEMAN Pneumo-Drier

Controls drying - handles moisture levels of up to 25%, depending upon the nature of the material. All
parameters are monitored continually to ensure effective and efficient drying.

Saves cost - a simple, robust system with few components, it replaces the dual systems used currently
t o dry and transport the material.

Enhances security - securely encloses the material being conveyed from time of entry until delivery.

Is compact and flexible - requires far less headroom than existing systems, whether it is a new or
replacement system.

Is environmentally friendly - completely encloses the conveyed product, thus preventing contamination
of either the product or the surrounds.

Has optimum availability - requires minimal maintenance.

Specifications - the Pneumo-Drier can convey up to
20 t/h and, depending on the thermal properties of the material, will dry at up to 350° C.

BATEMAN dilute-phase conveyors

Pressure and vacuum systems

BATEMAN systems collect and discharge granular material from one or many points and are
particularly economic and efficient for conveying relatively low tonnages over short routes.

Use pressure systems for multi-discharge point-transfer systems.
Use vacuum systems for multi-collection point-transfer systems.
Convey food, plastics, chemicals, powders, wood chip, sawdust, tobacco, cement, scrap metal, ores, etc.

BATEMAN dilute-phase conveyors
Are hygienic - vital for food products.
Have optimum availability - require minimal maintenance.
Specifications:
- throughputs from a few kilogrammes per hour to over 50 t/h
- handle particle sizes from 1 mm to 40 mm
- conveying routes may be horizontal, vertical and tortuous, from a few metres to over 200 m
- the propelling force is provided by Roots-type blowers;
  - pressure systems typically use a maximum pressure of 60 kPa (g)
  - vacuum systems typically use a maximum vacuum of -40 kPa (g)

BATEMAN boosted dense-phase pneumatic conveyors

These systems utilise the low-velocity and high-pressure conditions ideal for the high-rate conveying of
aeratable or non-aeratable abrasive or friable powdered materials.

BATEMAN boosted dense-phase pneumatic conveyors

Minimise pipeline wear:

- due to the ultra-low conveying velocities.

Specifications

Capacities of a few t/h to more than 400 t/h can be achieved through either top discharge or bottom
discharge conveyor vessels

Distances of up to 2 kilometres can be achieved utilising the 'Cyclonaire' injector technology

The motive force is a high-pressure, low-volume air supply. Pressures are typically in the range of
100 kPa up to 600 kPa.
Cyclonaire Injectors

Injectors are fitted to BATEMAN dense-phase pneumatic-conveying systems handling powdered
materials which tend to pack under pressure. The small particle size of powdered material usually
prevents any air from flowing through slugs of such a material in the pipeline.

When the length of a 'non-porous' slug becomes too long, the friction against the pipe wall becomes
greater than the available force (pressure) pushing it along the pipe. At this point the slug becomes a
plug and blocks the pipe.

The injectors control slug lengths in the pipe, preventing blockages and making it possible to re-start
the flow of material when the line is full. They are typically set up to operate at 120 kPa above the
conveying-line pressure.

BATEMAN BATCAT - Capsule-carrier conveying systems

BATEMAN's high-security capsule / tube-mail system gently transports valuable and friable materials.

Use the BATCAT to transport diamonds, diamond and precious metal concentrates, pharmaceuticals,
chemical products and other precious materials.

The BATCAT received a 2000 Design Award from the S.A. Institution of Mechanical Engineering

The BATEMAN BATCAT

Has high levels of security:

no direct personnel access to transported material during commissioning, operation or maintenance
fully automated, remotely-controlled system, robust and tamper resistant
self-cleaning operation, with no material hang-up or spillage at transfer points.

Transports gently and caringly:

minimal inter-particle abrasion or impact during encapsulated point-to-point transport
gravity drops of no more than 100 mm at transfer points.

Is versatile - adaptable to virtually any project size.
