Cym Materiales SA manufactures metal abrasive cleaners for on site or fixed installations (blast rooms) with cleaning capacities from 1.5 ton to more than 200 ton hour, adapting to the needs of each customer.
Of robust construction, specially designed to perform cleaning and reloading tasks of heavy abrasives (carbon or stainless steel shot) removing all types of dust, shells, worn abrasives and other contaminants from the good abrasive used in the shot blasting process.
Due to its great importance and decisive influence on the control of the costs associated with the blasting process, the cleaning and separation system of dusts and fine abrasive becomes a fundamental part of the blasting process. However, it does not always receive its due analysis and consideration, thus wasting an unbeatable opportunity to optimize the process, reduce costs and achieve higher quality results. The shot blast cleaning system basically has two fundamental functions:
It is important to highlight that, in surface preparation processes for paint application, fine contaminants (powders, flakes, etc.) that are not removed from the shot blasting mixture can remain deposited between the peaks and valleys on the surface of the blasted part. When the paint is applied, the dust is trapped between the paint and the steel, reducing the contact adhesion that both surfaces should have. If the contaminant also penetrates the paint, it can produce corrosion cells in the steel, increasing the likelihood of premature coating failure.
It has been proven that for shot blasting and/or desanding of castings, the presence of 2% sand in the blast media considerably increases the wear of the parts compared to the same process with contaminant-free media. This shows the importance of a well-regulated blast cleaning system and its decisive influence on equipment maintenance costs. A well-regulated cleaning system allows:
Three lines of abrasive cleaning equipment available
Metal abrasive cleaning system of economical construction to allow easy transportation to the site with a cleaning capacity of 1.5 to 2.5 tons/hour. The abrasive is manually loaded into the cleaning system and after passing through the cleaning system is deposited in containers that are located at the bottom of the equipment. The coarse debris is retained by a sieve mounted for this purpose and the fine debris (dust) is captured by a cartridge filter mounted on the unit.
The equipment is composed of
The ARC-Compact and ARC-Stationary cleaning systems are designed to perform the cleaning and reloading of steel shot, either in fixed equipment in the plant or in the compact version mounted on a frame that allows an easy transfer to the site. Cleaning capacity of 10 ton/hour (according to need we have developed cleaners with capacities higher than 200 ton/hour).
The abrasive to be recovered is loaded into a hopper located at the base of the bucket elevator, which then discharges into the shot blast cleaner in two cleaning stages: one mechanical by sieving and the second by air flow. The coarse debris exits the circuit into a container mounted for this purpose and the fine debris is captured by a cartridge filter mounted on the unit. The cleaned and recovered abrasive is deposited in a storage silo ready for reloading the pressure blasting equipment.
The ARC-Compact and ARC-Stationary cleaning systems consist of:
Compressed air particle blasting equipment works indistinctly with any type of abrasive (metallic, mineral, plastic), allowing the selection of the most suitable for each type of work.
In the case of closed enclosures, it is extremely advantageous to use metallic abrasive blasting media compared to other abrasives, since the following advantages stand out:
