Some users who buy granulator do not know much about stainless steel material of granulator. No matter NPK fertilizer granulator, organic fertilizer granulator or stainless steel disk pan granulator, when customers choose some materials or the whole machine uses stainless steel materials, they must have a certain understanding of stainless steel materials, or they may buy inappropriate equipment.
There are 201, 202, 304, 316, 316L stainless steel commonly used in machinery manufacturing industry. Now let the disc pelletizer manufacturers introduce how to distinguish stainless steel equipment.
In fact, the material of 201 and 202 stainless steel is not much different from that of ordinary steel, but it has a little more antirust component than that of ordinary steel. It is the most common one in the quality of stainless steel. If it is used to make disc granulator, it will rust soon.
Magnet is used to distinguish 201 and 202 stainless steel. If the magnet has slight adsorption on the surface of the device, it is made of 201 or 202 material.
304 stainless steel disc pan granulator
304 stainless steel is common stainless steel, this stainless steel plate is commonly used in disc pelletizer. This kind of steel plate is much better than 201 and 202. The stainless steel pan granulator we usually tell our customers is 304 stainless steel. That is to say, this type of steel plate.
For the difference detection method of 304 material, magnet is also used. If there is no adsorption at all, it is 304 material.
316, 316L type stainless steel is better than 304, usually used in strong acid and strong alkali industry. These industries have strict requirements on the material of pelletizer, which is not only related to the quality of products, but also related to the safety of human life. Type 316L stainless steel is better than type 316.
The above is the type and distinguishing method of stainless steel material used in the disc granulator. Understand the material of the equipment to prevent the purchase of low-quality stainless steel pelletizer machine.
