Categories of Stainless Steel Vibrating Screen

Stainless steel vibrating screens can be designed according to the user's requirements for screening materials, with the contact part made of stainless steel and the entire machine made of stainless steel. Stainless steel vibrating screens can be divided into various materials, so which ones are specific? How is it distinguished? Next, we will introduce to you:

The below pictures are the full stainless steel rotary vibrating screen with powder coating treatment on the surface.

 

 

The stainless steel vibrating screen is mainly made of three types of materials: 201, 304, and 316 stainless steel:

1, Detailed explanation of common stainless steel models such as 201, 304, 316, etc.

1. Magnet identification

The commonly used 304 stainless steel vibrating screen does not have adsorption force when approached with a magnet, while low-quality 201 stainless steel magnets will produce slight adsorption force when approached.

2. Identification of smoothness and brightness

After polishing, 304 stainless steel will have a smooth and clean surface on the screen machine, while low-quality 201 stainless steel will have some pits, dark spots, etc. on the surface of the vibrating screen after polishing.

3. Identification of chemical solutions

The above two methods mainly focus on the identification between 201 and 304 stainless steel, and have little effect on the identification of 304 and 316 stainless steel. Dahan manufacturers can quickly distinguish different materials of stainless steel through chemical solutions. Specific usage methods:

2, Method for distinguishing stainless steel vibrating screens of different materials

Drip 1-2 drops of stainless steel identification liquid onto the material to be tested, wait for a few seconds, and the display effect: (If there are stains on the surface of stainless steel or coatings, they must be treated thoroughly before testing)

① Nickel free material, the liquid droplets instantly turn dark red;

② 201 stainless steel, the liquid droplets instantly turn deep brown red;

③ 202 stainless steel, droplets turn pale brownish red in about 5 seconds;

④ 301 stainless steel, droplets turn pale brick red in 1-2 minutes;

⑤ 304 stainless steel, droplets do not change color within 3-5 minutes.
