Granulated copper slag
The Uralgrit company is a producer of granulated copper slag for sandblasting, supplying products both throughout Russia and to neighboring countries. The production of copper slag in accordance with international standards is carried out on modern equipment, which guarantees high quality of manufactured abrasive products.
Copper slag is a modern granular slag that makes it easy to remove persistent dirt, mill scale, and corrosion products using sandblasting. Cooperslag is suitable for high-performance abrasive cleaning of steel and concrete, for uniform surface profiling. It is used for abrasive preparation of surfaces for further staining. Today, copper slag is the most common type of slag used for abrasive cleaning of various materials.
Cooper slag is produced from granulated slags obtained by melting copper. As a result of production, copper particles are absent in the cooper slag. The granule sizes of the cooperslag produced by us do not exceed 3.15 mm, and the proportion of particles less than 0.2 mm in size does not exceed 5%.

Cooper slag consumption per 1 sq. km. surface meter
Cooper slag consumption per 1 sq. km. The meter of the processed surface is extremely individual and depends on:
Type of the processed surface (metal, brick, concrete, etc.);
The degree and type of pollution;
Technical capabilities of the sandblasting apparatus;
Cooper slag fractions;
Sandblasting qualifications.
For the average consumption of granulated slag (nickel slag / copper slag), we recommend that you focus on the data of the Central Research Institute of CM "Prometey" issued in the publication "Guide for the training of inspectors on visual and measuring quality control of painting work", which is from 24 to 78 kg / m2
It should be borne in mind that the average consumption of granulated slag (nickel slag / cooper slag) depends on the main parameters of the abrasive blasting plants (nozzle diameter, air flow, average productivity), as well as the required degree of surface cleanliness.
Advantages of copper slag for sandblasting
High abrasiveness due to the sharp angular shape of the granules and their hardness (6.0 on the Mohs scale).
Stable fractional composition of the powder.
The minimum humidity level allows the cooper slag to remain loose and not stray into lumps, thereby not clogging the abrasive line.
Low dustiness of the powder, providing a reduction in the dust cloud during surface cleaning, which allows to use cooper slag in small confined spaces (barrels, tanks).
Environmentally friendly material that does not harm either human health or the environment.
Advantages of Sandblasting with Cooper Slag
Achieving the degree of purification of Sa3 (pure metal without inclusions) and the roughness of the profile of the treated surface.
Significant material savings in the cleaning process at a higher productivity.
The low level of dust during the cleaning process eliminates the risk of occupational diseases of abrasive blasting operators.
