Winter Grinding Mill Protection

Winter Grinding Mill Protection

Cold winter mill grinding mill protection knowledge

The cold winter has arrived, the protection of the grinding mill equipment needs to be strengthened, especially the environment of the mill equipment working outdoors is very bad, because the working objects are generally harder stones, so it is easy to wear, plus The weather is cold and the air becomes moist, making the mill particularly prone to rust. The rusting of the mill will affect the work efficiency, the output will be reduced, and the production will be discontinued, and even repairs will be made.

First, the easiest and most effective way to prevent the rust of the mill is to apply anti-oxidation paint to the mill, apply mineral oil, paint or fire enamel, spray, etc. on the surface of the iron. A layer of metal that is not easily rusted, such as zinc, tin, chromium, nickel, etc., is plated on the surface of the steel by electroplating or hot plating. These metal surfaces can form a dense oxide film to prevent iron products from rusting by contact with substances such as water and air. In addition, if it is found that the metal surface of the grinding mill has fallen paint, it is necessary to apply anti-oxidation paint in time.

As far as I know, some users in severe cold areas are in a state of discontinuation due to the low temperature in winter. Therefore, the mill should also be stored in a dry and ventilated environment when it is shut down for storage. The best parts are Apply oil to all parts. When it is found that the mill has rusted, there are three solutions. First, chemical derusting can be utilized. In the chemical field, acidic substances can chemically react with metal oxides, thereby removing the rust products on the metal surface of the grinding mill, which is commonly referred to as pickling and rust removal, and can only be operated in the workshop.

Then, the high-pressure water abrasive is used to remove the rust, and the impact of the high-pressure water jet and the action of the water raft are used to destroy the corrosion and the adhesion of the coating to the steel plate. It is characterized by no dust pollution, does not damage the steel plate, greatly improves the rust removal efficiency, and has high rust removal efficiency. However, the steel plate after rust removal is easy to return to rust, and it is necessary to apply a special wet rust-removing paint, which has a great influence on the coating of general performance paint. It can also use electric descaling, mainly powered by electric or compressed air, equipped with appropriate descaling device, reciprocating or rotating motion to meet the rust removal requirements of various occasions. The maintenance of the grinding mill is nothing more than anti-rust and anti-aging. Now we have taught the method to everyone. We hope that the users will do the maintenance work on the grinding mill in this cold winter to avoid unnecessary trouble.
