This action erodes material by deflation—the removal of small loose particles—and by sandblasting of landforms by wind-transported material. Continued deflation of loose particles from landforms leaves behind larger particles that are more resistant to deflation. Wind action transports eroded material ...
Its agricultural applications, however, have dwindled considerably in recent years because of the growth of ammonium nitrate and other fertilizers.Another major use of sodium nitrate is in manufacturing explosives. It is a component of many types of dynamites and water-based slurry type blasting ...
While the Wiedouw marble and the Rooikop limestone form compact and tough rocks requiring higher costs for blasting, crushing, and grinding for the small quarry, the Rietfontein calcrete, being of secondary surface origin, is softer and is therefore preferred ahead of the other two....
cutting, machining or grinding of metal) and industrial abrasion processing with high release rate (e.g. sanding operations or paint stripping by shot-blasting). This substance can be found in products with material based on:
blasting Sprengung, die (eng.) Blasting activities in a quarry need to be well planned. blasting agent Sprengstoff, der (chem.) Blasting agents are capable of developing a high amount of heat and gas within a short period of time. blasting fuse Zündschnur, die (chem.) Blasting fuses ...
Poster cumulatively-chemical device relates to oil and gas industry for high-level simulation of response processes of chemical reagents (ef) from the oil reservoir rocks, which can be used to develop a new type of shooting-blasting apparatus of improved efficiency, namely cumulatively chemical ...
Initial gold concentration occurred>200 ky ago on exposed sandy beaches, where sand-blasting processes deformed fluvially-transported (~200km) flakes into toroids, dumbells and spheroids. This gold was recycled into younger gravel-bearing sediments 50m) with negligible morphological changes during<10km...
is that while the Wiedouw marble and the Rooikop limestone prove to constitute compact and tough rocks, requiring higher costs for blasting, crushing and grinding for the small quarry, the Rietfontein calcrete turns out to be softer and, therefore, highly preferred in respect of the former two...

Sintered bauxite is often used as a sand-blasting abrasive. It is produced by crushing bauxite to a powder and then fusing it into spherical beads at a very high temperature. These beads are very hard and very durable. The beads are then sorted by size for use in different types of sand...
