- the flash dryer was gassed with air or an air / ammonia mixture 1: 1 (approx. 110 m 3 / h); the gas outlet temperature was approx. 65 ° C.
- the pre-dried, still about 60 ° C hot granules were placed on a vibrating trough (length 1 m), gassed with room air and cooled to about 40 ° C within 30 s. It was then powdered with about 1% by weight of silica (Sipernat® 50 S). A dry, pure-white granulate which was free-flowing and non-clumping, even after long storage in the air, was obtained. The characteristics of the granulate are shown in Table 1.
- Examples 6 to 8 show that, with the water content of the end product remaining the same, the throughput of paste could be increased from 8.5 to 13.5 kg / h when the powder recycling was used. The quantity recycled could be varied within a wide range (examples 7 and 8).
- the product according to Example 8 is considerably coarser than Example 1.
- Examples 9 and 10 show that an increase in throughput without powder recycling can lead to an increase in the product water content from 0.7 to 1.3% by weight.
- the powder recycling (example 11) reduced the product moisture and again led to powders with a lower dust content.
