Phosphate Processing
 |
The application
area for the different kinds of phosphates is extremely
wide and varied. Whereas phosphate is mainly used in fertilisers,
it is also employed as an additive in the production of
adhesives, plant protectors, plastics, foodstuffs, medicines
and cosmetics.
Besides the manufacturing process itself, the vast range
of applications calls for versatile processing systems
that can deliver the desired particle size distribution
from the previously dried feed material. For many years,
Hosokawa Alpine has been using the Zircoplex classifier
mill ZPS for this task. Thanks to the integrated classifier,
this machine can be set to the fineness that is required
in each individual case and is thus universal in use. |
The flowchart below shows a schematic of such a grinding-classifying
system.
The system layout bases on the following specifications:
| Feed material: |
from the dryer with a moisture content
of 3.5% H2O |
| Feed size: |
< 4mm |
| Desired end product: |
d97
10 - 45 µm |
| System throughput: |
approx. 1300 kg/h at 45 µm |
| Machine size used: |
630 ZPS |

Systems with throughput rates of between
100 and 1800 kg/h are available to suit individual requirements.
