Dilute-phase
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)
Medium-phase
These systems provide the optimum solution for the medium-rate transfer of aeratable abrasive or friable materials.
- Specifications:
- capacities of up to 80 t/h are possible through various modes of loading and unloading
- air is delivered via a Roots-type blower at pressures up to 120 kPa (g).
Boosted dense-phase
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 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.
Dense Phase 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.
