Definitions
- Roll compacting of detergents or cleaning agents or individual components of detergents or cleaning agents is a state of the art. It is already known from European patent application EP-A-0253323 that builders such as zeolite and / or phosphate can be converted into granules with high bulk density and very good application properties by roller compaction. The conditions under which roller compaction is usually carried out are described in detail in this prior art document. It is stated that the pressing pressure in the nip and the duration of the material in the area of the pressing pressure are to be set in such a way that a well-formed band of high density is produced.
- the bulk density of the granules compacted according to the invention is then preferably even 700 g / 1 to 1100 g / 1 and in particular even 800 to 1000 g / 1.
- a bulk density of the compacted silicates is set which is preferably at least twice and in particular at least three times the bulk density of the light starting silicates.
- the water content of the compacted silicates is 0 to a maximum of 15% by weight. However, as with the light starting silicates, preferred water contents are 3 to 15% by weight and in particular 6 to 13% by weight.
