摘要:
A method and apparatus are disclosed for continuously drying, preferably with agglomeration and/or coating and sizing, and separating a solid product from a liquid feed material, especially bauxite slurry which passes through a very sticky phase during drying, without significant encrustation of the equipment used. The method comprises: spraying a liquid bearing solid material upwardly into a drying zone, feeding a drying gas into the drying zone from below The spraying liquid in substantially parallel flow, removing the mixture of the drying gas and entrained dried particles from the drying zone, separating the entrained dried particles from their mixture with the drying gas, returning the separated dried particles to the drying zone, and collecting the dried particles, characterized by arranging for the formation of a slower moving boundary layer within the feeding of the drying gas, through which boundary layer dried particles are allowed lo fall under gravity to be collected, and by collecting the dried particles continuously from below the spraying liquid.

The invention is related to climbing trees. Climbing trees are used for a variety of purposes—cats and other pets and small or slightly older children can derive a lot of pleasure from activities in a climbing tree. Using a specially designed bracket the shape of the climbing tree can be expanded and changed in an almost unlimited range of combinations. The climbing tree can be adapted to the physical aspects of its surroundings. These make the climbing tree exceedingly useful and practical. The new invention consists of different types of brackets to be secured to the columns and where the brackets are the link to new imaginative additions to the climbing tree. The invention can fulfil claims in which the column can have any shape imaginable—e.g. square, triangular—such that the brackets are simply physically shaped to suit that of the column.

The invention relates to an apparatus and a method for manufacturing clinker, such as cement clinker, in which the majority of the raw materials is present in a hydrous slurry.Initially, the slurry is dried in a gas suspension drier, and the raw materials are subsequently passed to a thermal unit in which the heating of the raw material is effected fairly quickly so that all organic compounds are destroyed in the thermal unit.Subsequent to being heated in the thermal unit, the raw material is directed to the kiln in which it is nodulized and burned into clinker.
