Bead blasting is the process of removing surface deposits by applying fine glass beads at a high pressure without damaging the surface.
ApplicationsIt is used to clean calcium deposits from pool tiles or any other surfaces, remove embedded fungus, and brighten grout color. It is also used in auto body work to remove paint. In removing paint for auto body work, bead blasting is preferred over sand blasting, as sand blasting tends to create a greater surface profile than bead blasting. Bead blasting is often used in creating a uniform surface finish on machined parts. It is additionally used in cleaning mineral specimens, most of which have a Mohs hardness of 7 or less and would thus be damaged by sand. Hardness Moh: 5-6, Surface profile: low etch – satin, Surface removal: Slight, Recyclability: High, Working Speed: Medium – fast
Mixed with very high pressure water, garnet is used to cut steel and other materials in water jets. For water jet cutting, garnet extracted from hard rock is suitable since it is more angular in form, therefore more efficient in cutting.
Sharp, angular long - lasting media for fast etching and profiling resulting in an anchor peak to valley profile, nonetheless, extremely abrasive on working parts excess use will require shorter intervals for the replacement of functioning parts.
Hardness Moh: 8-9, Surface profile: High etch, Surface removal: Yes, Recyclability: High, Working speed: Fast
Slag is a constant by-product of the metallurgical industry, which has been treated, recycled and used worldwide. The metallurgical oxide slags have stone-like properties and thus, their major applications are in the civil engineering field. Due to the high cost of natural material and the rising emphasis on sustainable construction, the construction industry uses our aggreagtes as a viable alternative.
In concrete, the slag or natural aggregate makes up 70% of the concrete volume, and is one of the main constituent materials in concrete production.Typical applications•Road pavement layers: subbase -, selected-, and fill layers.•Mechanical modification and chemical stabilisation.•Concrete aggregate/seal aggregates/asphalt aggregate/slurry aggregate/ subsiol aggregate.•Gravel roads, improving the strength of gravel roads (less maintenance).•Strengthening of haul roads (less maintenance).•Run off dump slag for fill applications.•Bedding material and backfill for stormwater pipes.•Rehabilitation of mining areas.•Wash/parking bays.•Electrical KVA yards.•Stemming material to insulate an explosive charge.•Manufacturing of paving, and building bricks.•Preamble reactive barrier to remove contaminants from water.•Increase soil texture by breaking down clay-like soil.
Our process design is based on accomplishments realised and lessons learned from the many plants built in the past.Utilising our vast process development, design and project engineering capability combined with extensive operating experience, our plants ensure optimum capital and operating costs for high recovery.
Crushing, screening, slimes handling and water reticulation form part of the process, and all by-products of the process are managed in an environmentally safe fashion.

Historic overview of slag in road buildingThe first appearance of slag was recorded as early as the year 700B.C.It can also be concluded that the history of slag is as old as the melting process in which it was generated. The first modern roads in which slag was utilised, were built in England in 1813. As early as 15 years, after good experiences with the application of this material in road building were confirmed, slag started to be used in railway construction as well. Since then, blocks obtained by casting of slag have been massively applied in Europe/America for road pavements.
The use and advantages of slag in road building:•Sharp edges, a proper grain shape, and rough surface texture also contribute to better adhesiveness of aggregates binder and grain, and increase the co-efficient of internal friction of bituminous overlay more than any other natural aggregate.•Physical properties, in addition to proper granulometric composition, increase shear tightness of mixtures and resistance to appearance of rutting.•Slag is harder and internally bound, natural gravel does not have the same stability and load bearing capacity.•Due to slag being harder and more compact that natural rock, roads last longer with less wear.•In contrast, natural rock becomes smooth with wear and its surface becomes polished and slippery.•As a result, tyres can grip better on surfaces constructed using slag, and this is particularly important on highways and in curves.
