Problems solved by technology

Since the blasting material is usually circulated and reused in the blasting equipment, on those workpieces it will lead to the accumulation of impurities in the blasting material, resulting in increased cleaning costs for the blasting equipment and blasting material
For this reason, it is often prescribed that the manufacturer of the blasting equipment carry out a pre-cleaning treatment of the workpieces which, due to the solvents used, involves a considerable risk of damage to human health and the environment and entails correspondingly additional costs

Embodiment Construction

[0018] The exemplary device proposed by the invention has a sandblasting device 1 in which a sandblasting jet 3 is sprayed onto a workpiece 2 . The blasting material 5 used is collected and conveyed to a treatment device 8 in which a first fraction 13 (which essentially comprises the original blasting material and unfragmented additive fraction) and is separated from a second portion 12, which is preferably discharged by a carrier air flow, and which contains the fragmented additive fraction and the wear of the workpiece and / or blasting material substances and impurities to be removed from the process. This second part 12 can be removed from the carrier air flow by means of a filter, so that only waste gas free from impurities remains in the carrier air flow.

[0019] According to the invention, a device 7 is provided for the metering of granular additives 6, the function of which is to add the additives to the circulated blasting material 5, the added additives are preferabl...

Abstract

The invention relates to a blasting agent (4), which has at least one means for mechanically processing surfaces, in particular steel or cast beads. An additive (6) for degreasing and cleaning the surface (2) to be blasted and / or the blasting agent is provided, said additive comprising a granular material, which has a lower fracture strength than the at least one means for mechanically processing surfaces itself under the mechanical loads to which the blasting agent (4) is subjected during the blasting method.

Description

technical field [0001] The invention relates to a sandblasting material and its manufacture, and also relates to a sandblasting method and a device for implementing the sandblasting method. Background technique [0002] Sandblasting methods are known from the prior art. Common to these blasting methods is that a material for mechanical surface treatment (hereinafter also referred to as the actual blasting material) is sprayed onto a surface to be blasted, usually in granular form. Granular material is to be understood in a broad sense as a granular material which consists of particles with a defined particle size distribution, symmetrically shaped particles such as beads, in the following, also to be considered granular material. Here, the shape, the particle size distribution and the material used for the particles have to be selected according to the material of the workpiece to be treated and the effect of the desired blasting process on the workpiece. Process purposes ...
