The methods to maintain long unused sand maker

Hongxing Machinery sand production line has realized automatic control of production, and the production scale can be easily controlled to configure the best and most economical production line. The construction of buildings needs a large amount of sand, but their requirements for sand quality are not the same. The major difference between artificial sand and natural sand lies in the rough appearance and non-performing shape. Rough appearance and unrounded shape cause adverse effects for the mobility of concreting, which will result in voids into concrete. And it can be said that the sand maker directly impacts the quality of the project. Therefore, the quality of the artificial sand should be mainly decided by rough appearance and circularity of the sand. In addition, limitations of raw materials of artificial sand and other synthetic materials must be seriously faced by the manufacturing industry and construction enterprises. With the perfection sand making manufacturing technology, the cost of artificial sand will not be much higher than the natural sand any longer, which is one of the reasons for the flourish of sand production line.

Sand Maker is a high-efficiency rock crushing equipment with home and international leading level; the machine is developed by introducing the crushing theory and technology from Barmag Company of America.

As with other ore dressing equipment, sand maker 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.

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.

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.
