Methods of Derusting for Sand Making Machine

FOR IMMEDIATE RELEASE
(Free-Press-Release.com) December 17, 2011 -- Sand making machine 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 and combining the actual situation of sand making. It is widely used for crushing of hard and brittle materials, such as rock, grinding material, refractory material, cement clinker, quartzite, iron ore and concrete aggregate; and it is especially suitable for the sand and sandstone making for construction and road paving.

The working environment of sand making machine equipment leads to the rusting of sand making machine, which is a normal chemical reaction. When the machine is placed in the air for a long time, it will be easy to get rusty. The working environment of sand making machine is generally quite poor, it is likely to get rusty and affect the production quality. So how to maintain and correctly operate the sand making machine equipment is becoming more and more important. Shanghai mining machinery co., ltd will introduce some good ways to derust and improve the operation in the sand production line.

1) Chemical derusting: mainly by the chemical reaction between acid and metallic oxides and thus remove the rust corrosion on the metal surface, which is known as pickling rust, and can only be operated in the workshop.

2) Small-sized pneumatic or electric derusting: electricity or compressed air is worked as driving force and equipped with suitable derusting device for reciprocating or rotary movement to meet the derusting requirements of a variety of occasions. For example, the angel grinder and wire brush which belong to semi-mechanized equipment are very light and handy, and of great mobility. They can completely derust but can not achieve high qualified surface treatment.

3) High-pressure water abrasive derusting: by the impact of high-pressure water jet (plus the grinding effect of abrasive), the prized role of water damage and corrosion and the coating¡¯s adhesion on the plate shelves. Its characteristics are: no dust pollution, no damage to steel and high derusting efficiency.

4) Daubing anti-oxidation paint derusting: daubing mineral oil, paint or enamel on the surface of ironwork, or plating a layer of metal such as zinc, tin, chrome, etc by electroplating or hot dip. The surface of these metals can form a dense sull that can prevent contacting with water, air and other materials.
