IPC: B01J2/28
Filed: 1988-04-09
Granted: 1989-10-12
Abstract: For a process for suppressing dust and fines during granulation of ammonium nitrate having a nitrogen content of 28 - 34.5% of N, a solution is to be found with which, in a granulation plant, an ammonium nitrate can be prepared having a narrow particle size spectrum, i.e. as great as possible an amount of ammonium nitrate is to be produced having a particle size of 1 - 4 mm 0. The formation of defective grains, in particular in the fines region, is to be suppressed. 
<??>This is achieved by forming the crude granules in screw, drum, spheroidiser and/or distributor granulators in a first granulation zone according to known granulation processes and fixing the dust and/or fines contents formed in the first granulation zone to the crude granules in a second granulation zone at 100 to 125 DEG C by addition of a di- or trivalent iron sulphate containing water of crystallisation in a suitable amount.

IPC: B41F15/16
Filed: 1990-07-25
Granted: 1991-09-19
Abstract: A method for manufacturing a flat and, in particular, large-area printing support especially for screen printing tables is proposed, in which method a liquid and readily flowable synthetic resin casting compound of, in particular, epoxy resin is applied to a base surface (13), which is bordered by upright support surfaces (24, 25) as an encasing, the compound is allowed to run freely and become evenly distributed and cure slowly. In this case, a flat and horizontal surface is produced automatically under the force of gravity so that a layer (11) is obtained after curing, whose surface (12), forming the printing support, is extremely level. Large-format printing support plates (10) can be produced quickly, simply and cost-effectively and repairs can be carried out on the surface of the layer.
