Abstract
An apparatus and a method for coating of surfaces with a combination of a solid material and a binder, so that despite of the unevenness of the area to be coated, a desired evenness is obtained controllably. In the invention the filler is slung through the liquid binder and that binder not captured by the filler particles onto their surfaces is recovered and reused.
Claims26
Method for producing a coating layer consisting of a solid material and a liquid onto a substrate, according to which method;
- the solid material is contacted with the liquid in order to form a mixture,
- the mixture containing the solid material and the liquid is sprayed onto the substrate,
- a liquid stream is formed from the liquid,
- the solid material is slung as a continuous stream through the liquid stream in order to contact the solid material with the liquid, and
- the flow of the solid material passed through the liquid is directed towards the substrate for coating thereof.

An apparatus for forming a mixture of a solid material and a binder, which apparatus comprises;
- feeding means for the solid material;
- feeding means for the binder
- a mixing zone for the solid material and the binder provided by the feeding means, wherein the solid material and the binder are mixed together
- an accelerating means for the solid material which is provided with an inlet coupled with the feeding means for the solid material and an outlet for the accelerated solid material, the accelerating means being capable of accelerating solid material fed through the inlet to a desired velocity with the aid of mechanic energy and said accelerated solid material being removable in the form of a continuous flow through the outlet and
- near the outlet arranged feeding nozzles of the binder that have been connected to the source of the binder and with aid of which the binder can be sprayed to the stream of the solid material,
- wherein the binder stream is arranged in front of the outlet in order to provide a mixing zone such that the flow of solid material withdrawn from the accelerating means is forced to pass through the flow of the binder.
