The various applications and blasting abrasives are presented to companies that commission contract blasting work and are given a choice. Here they benefit from the experience, competence and know-how of the spotlight. The result is a high degree of flexibility, reliability and efficiency.
Coating describes the process of applying an adhesive layer to a workpiece surface. The aim of a coating is to have a positive effect on the properties of workpieces, both chemically and physically. An important criterion for assessing the quality of coatings is their adhesive strength. It determines how well the applied layer holds on to the workpiece. This parameter can be massively influenced by processing the workpiece with an angular blasting medium.
The blasting process results in roughening of the workpiece. The resulting surface topography guarantees a considerable improvement in adhesion, resulting in a significant increase in the quality of the workpieces.
Clean water is the basis of all life and forms the basis of every development.
Multi-layer filters make a valuable contribution to significantly improving the cleanliness and quality of the water through optimal filtration.
Due to its hardness, high bulk density and chemical stability, Almadin garnet sand is an important component of a multi-layer filter, extending the service life of the filter system and ensuring a stable and high filtration rate.
Flooring / Anti-Skid
In accordance with the rules of the employers’ liability insurance association for “floors in work rooms and work areas with a risk of slipping”, floors must have sufficient anti-slip properties for the respective applications. At the same time, it must be ensured that a sufficient displacement space is achieved so that there is no risk of aquaplaning due to the presence of liquids.
Foundries are high-performance centres in which castings are manufactured from a wide variety of materials for the most diverse industries.
Many casting processes require a uniform surface finish at the end of the machining process. The desired performance is achieved by targeted blasting applications, which guarantee the high demands in terms of dimensional accuracy, mechanical load and surface quality, from complex individual parts to mass production.
The selection of the appropriate abrasive is essential for an effective and stable blasting process that guarantees the desired surface appearance.
Der The term laminate refers to a floor covering made up of several layers of laminate and provided with a binding agent. The overlay as the top layer takes on the task of protecting laminate flooring from everyday wear and tear. To ensure the desired abrasion resistance, corundum is added to the overlay adhesive.
Our premium-quality aluminium oxide has established itself particularly well, fulfilling not only the special requirements for abrasion resistance and transparency, but also the required degree of whiteness. The extremely high purity allows an unadulterated view of the decorative paper of the laminate.

Facades are constantly exposed to environmental influences and pollutants, which sooner or later lead to weathering. Soiled and discoloured surfaces are visually unattractive. A cost-effective and at the same time environmentally friendly solution without chemicals is offered by façade cleaning with the help of blasting agents. This process guarantees the removal of all types of impurities with the lowest possible loss of substance on the façade itself.
Mobile shot peening is mainly used in the areas of building renovation and new construction. It is an important preparation step for floors with special properties and requirements.
Mobile blasting machines discard small steel balls, which clean the surface to be processed without leaving any residue. Afterwards, a resilient and hard-wearing floor layer can be applied.
Modern extraction technology ensures that shot peening can be carried out almost dust-free despite the release of dirt and old coating. The abrasive is cleaned within the unit and used in the circuit for many cycles. As with other blasting applications, the correct choice of blasting medium is decisive for the economic efficiency and the result of the process.
Surface technology is also an important factor in the offshore sector. The constantly changing weather conditions place special demands on the slip and abrasion resistance of coverings (anti-skid). At the same time, it is important to ensure the corrosion resistance of these coverings and other components that are exposed to constant weathering. These special requirements can be met both by the right coating and by the right processing.
Pyrotechnics refers to a technique that is connected with combustion, usually of an explosive nature. The best known area is probably fireworks. In order to generate the most diverse effects of rockets or fountains, different metals and chemicals are used and combined with each other. In order to achieve the colour effects, they are mixed with a binder, moistened and brought into the desired shape.
Refractory products are used wherever work is carried out at high temperatures > 600 C°. Kuhmichel supplies raw materials which, as an essential component of many end products, contribute to an efficient production process. Our electro-corundum is characterised by good thermal and chemical resistance.
Steel And Metal Construction
In steel and metal construction blasting applications are used in many areas. Often, blasting applications are the only economical solution when it comes to achieving the desired component properties. These include the fulfilment of specified purity and roughness values, the hardening of components (shot peening) and deburring.
The variety of applications, specifications and equipment technology requires a targeted selection of blasting media which act as tools and thus provide the desired surface.
In the industrial processing of stone, the fields of application for surface technology are very versatile. From the smoothing of stone surfaces for optical refinement, to engraving blasting work on all types of stone, to the processing of floor slabs to improve anti-slip properties – abrasives are indispensable and play a decisive role in the success of the applications.
From production to completion, tools go through a large number of processing steps. As specific as each tool is suitable for specific applications, so is its surface treatment. Established applications include both descaling and deburring as well as roughening as a pre-treatment to improve the adhesion of a subsequent coating. As a final machining step, many tools receive a surface finish. This gives us a tool that meets the highest technical and optical standards.
The use of blasting abrasives for surface treatment plays an important role in the manufacture and maintenance of rail vehicles and rail vehicle components. The properties of components can be significantly improved by targeted blasting applications. The blasting technology is used to prepare surfaces for subsequent coatings and to increase the service life of work parts.
