Blast media recovery
The consumption of abrasive is a significant cost factor in abrasive blasting or sandblasting. Therefore, the recovery and subsequent recycling of abrasive in sandblasting systems is essential. The choice of abrasive recovery is an essential part of all blasting work, both mobile and stationary.
Clemco divides the recovery system into three basic principles:
Manuell / Sweep In: In this process, the used abrasive is conveyed by hand back to the blasting pot or to a processing system such as a bucket elevator with cleaner. This is a cost-effective way of recovering blasting abrasive, but it also limits the blasting operation and requires additional working time, which must be used to collect the used abrasive media.
Automatic systems: A fully automatic system saves the user time and allows him to concentrate fully on sandblasting. In a blast room, a scraper floor is used for this purpose, which automatically transports the used abrasive to the abrasive processing system. With regular sandblasting, the costs for an automatic system are amortized after a short time, as no working time is required for the collection and return of abrasive. This also means that the blasting process does not have to be interrupted.
Vacuum systems: Vacuum systems such as a suction system are particularly suitable when blast media is transported over long distances. The blast media can be transported up to 120m via a Clemco suction system, similar to a vacuum cleaner. This method is suitable, for example, in very large blast rooms or for free blasting, but also if there are restrictions in the foundation or height due to structural conditions.
The Clemco M-Section also uses the principle of negative pressure and is particularly suitable for light media such as glass beads. The simple and economical design makes this system particularly efficient and suitable for smaller blast rooms.
An automatic recovery system is also included in most Clemco blast cabinets. The vacuum process is used and an automatic cycle is generated so that the user does not have to worry about the preparation of the blast media. This is conveniently taken care of by Clemco's harmonized cabinet system.
Either way, it is an essential element of sandblasting, not only in terms of environmental protection, but also from an economic point of view, if the used blast media is recovered and processed by a blast media recycling system.
