Long-term unused
should be given due care and maintenance
As with other ore dressing
equipment, should be given
more attention to maintenance when isn't in use for long time. Hereby, we
introduce you an economic method, that is dilute hydrochloric acid. However, you
should be care that rust things should not immersion too long, or the metal will
take chemistry reaction. And other methods, such as ash propel and shot blast
are also available. Then I will introduce you related information in
details.
At first, chemistry method, as its name, makes use of chemistry
reaction to remove rust. We common say it acid dipping, and it can only done in
workshop.
Another method is shot blast cleaning. Shot-blasting abrasives and
polishing makes use of high-speed rotating impeller throwing grinding materials
to the steel surface, so as to achieve the purpose of rust removal. It is a more
advanced steel rust method for sand making machine cleaning processing. It is
not only high efficiency, but also low cost, high degree of automation, and it
is able to implement assembling operation, less environmental pollution, but it
only available for indoor operation.
Peening rust, an old kind of cleaning
method, mainly use particles blast erosion effects posed to reach the
appropriate roughness of the surface and cleaning. The relative equipment
includes open shot (sand) derusting machine obturation shot peening (sand),
vacuum shot blasting (sand). Open blasting (sand) is applied more widely,
providing more thorough clean all impurities of metal surfaces, such as
oxidation, rust and old paint, rust removal efficiency is as high as 4~5m2/h,
high mechanical degree, good effect. But the abrasive generally cannot be
recycled, and it has an impact on other jobs, has trouble in cleaning up the
work site. The environmental pollution is more serious, in recent years, it
gradually been restrictions in use.
Small pneumatic or electric device is another rust removal way. It mainly
takes electricity or compressed air as power, assembling appropriate blasting
device. And then it does oscillating movement or rotation to suit various rust
removal occasions. The equipment are corner polished machine, wire brush, wind
dynamic needle beam rust removal device, wind dynamic knock rust hammer, tooth
type rotating rust removal device, they are belonging to half mechanized device,
tools are light, and large mobility. So, this way can more thoroughly remove
rust, and old coating. It can do roughness removal process to application layer.
The efficiency is higher than manual rust removal, can be up to 1~2m2/h, but
cannot drop oxidation skin.
All in all, the four methods we provide you for
sand making plant maintenance and rust removal. In reality living, there are
some ways are useful for our daily life. Hongxing Mining Machinery include many
other equipment, the leading products are sand maker, and so on.
