Explain how sand making machine rust?

Sand making machine is a new crushing concept of equipment, mainly for soft, medium and hard materials broken and plastic. This equipment has more than 30 years of history, widely used in metal and non-metallic ore, abrasive, cement, refractory materials, glass raw materials, artificial sand and a variety of metallurgical crushing and coarse grinding operations, especially for high hard And abrasion resistant materials are more effective than other types of crusher production.

As the working environment of the sand making machine is relatively poor, so there will be rust problems, affecting the quality of the equipment, then we talk about the method of derusting rust.

1, the use of high-pressure water jet impact and the role of water to remove the sand machine on the rust and coating. It is characterized by no dust pollution, no damage to steel, greatly improve the efficiency of rust, up to 15m2 / h above, rust quality is good. But rust after the steel is easy to rust, to be coated with a special wet rust coating, the general performance of the paint coating has a greater impact.

2, in the iron surface coated with mineral oil, paint or fired enamel, spray and so on. In the steel surface with electroplating, hot plating and other methods coated with a layer of metal is not easy to rust, such as zinc, tin, chromium, nickel and so on. These metal surfaces can form a dense layer of oxide film, so as to prevent iron and water, air and other substances in contact with rust. Chemical methods can also be used to produce a layer of dense and stable surface of the oxide film to prevent rusty iron products.

3, small wind or electric rust: the main electricity or compressed air as the driving force, the appropriate assembly of the rust device, the reciprocating motion or rotary motion to meet the requirements of various occasions, rust.

4, mainly the use of acid and metal oxide chemical reaction, so as to get rid of high-performance sand machine metal surface corrosion products of a derusting method, which is commonly referred to as pickling rust, the rust can only be in the workshop Internal operation.
