sand maker equipment is in use

When the sand maker equipment is in use and idle, good rust prevention measures

When the sand making machine equipment is used and idle, it must be maintained and maintained. It cannot be lax. Good performance equipment can bring better profits for the enterprise.

I. Rust prevention method:

• 1. Plating heat method. Metal materials, such as aluminum and zinc, which are not easily rusted on the surface of the sand making machine, such as aluminum and zinc, can form a dense oxide film on the surface of the sand making machine to achieve the The material must not come into contact with water and air, so it will not rust;
• 2. Coating method. Applying oily materials and paint on the surface of the sand making machine can isolate the iron of the sand making machine from external water and oxygen, thereby achieving oxidation and rusting of the sand making machine;
• 3. Material law. General sand making machines are made of iron. In order to prevent rust, we can use alloy materials to produce sand making machines, which can fundamentally solve the problem of rusting sand making machines;
• 4. Environmental law. Sand making machine rust is generally an oxidation reaction between iron and water, so by keeping the working environment of the sand making machine dry, it can also prevent the sand making machine from rusting.

II, rust removal

It plays a great role in the production of sand and gravel. Natural sand and gravel are gradually reduced, and artificial sand will gradually replace natural sand and gravel. The new sand maker will also have some problems in the process of use. Due to the working environment of the sand maker It is relatively harsh and not used for a long time, so the new sand making machine will have the problem of rusty surface, which will affect the quality of the sand making machine. How to remove the rust of the new sand making machine is very important, so based on previous experience for everyone Share several rust removal tips of sand making machine.

First of all, I would like to remind everyone that most of the mining equipment such as sand makers, crushers, and mills are basically made of steel. The long-term open-air operation or sufficient water vapor, plus a period of inactivity, Body rust is a normal chemical reaction. There is also the rust of the crushing cavity inside the machine. This is because its inner wall and materials (usually hard rock, ore, etc.) are rubbed during the crushing process, scratching its inner wall, and it is easy to rust if it is left for a long time. It is not important to rust, but it should be handled in time to prevent its long-term rust, causing damage to the machine and affecting the normal use of the sand making machine. There are four main methods to remove rust:

• 1. Chemical descaling method: It is mainly a method of removing rust by effectively reacting the acid with metal oxides to remove the rust products on the metal surface of the sand making machine, which is commonly referred to as pickling and derusting. Rust can only be operated in the workshop;
• 2. High-pressure water abrasive rust removal: Use the impact of high-pressure water jet (plus the abrasive grinding effect) and water pry to remove the rust and coating on the steel plate of the sand making machine. Its characteristics are no dust pollution, no damage to the steel plate, greatly improving the rust removal efficiency, which can reach more than 15m2 / h, and good rust removal quality. However, the steel plate after rust removal is easy to return to rust, and special wet rust removal coating must be applied, which will greatly affect the coating of general performance coatings;
• 3. Small-scale pneumatic or electric rust removal: It is mainly powered by electricity or compressed air, equipped with appropriate rust removal devices, and reciprocated or rotated to meet the rust removal requirements of various occasions;
• 4. Apply anti-oxidation paint: apply mineral oil, paint or fired enamel, spray plastic on the surface of iron products. On the surface of steel, use a method such as zinc, tin, chromium, nickel, etc. These metal surfaces can form a dense oxide film to prevent iron products from contacting water and air and rust. Chemical methods can also be used to form a dense and stable oxide film on the surface of iron products to prevent iron products from rusting
