a. The air flow screen is not suitable for screening materials with viscosity, water content> 5%, flammable, explosive and other materials;
b. With the same type of air flow screen, the larger the screened material mesh, the lower the corresponding output;
c. The following items should be stated when ordering:
1) The name and bulk density of the target screening material;
2) Material size and water content;
3) Requirements for output;
4) Screen mesh number;
5) Screening standard mesh materials should account for about 85% of the total materials;
6) The air flow screen can only screen materials of one mesh at the same time. If you need to screen materials of several meshes at the same time, multiple machines need to be connected.

1. Magnet identification
The 304 stainless steel commonly used in stainless steel vibrating screens will not have adsorption force when using a magnet, while the inferior 201 stainless steel magnet will have a slight adsorption force if it is near.

2. Identification of finish and brightness
After polishing the 304 stainless steel, the surface of the screen is smooth and tidy, while the inferior 201 stainless steel will have some pitting and dark spots on the surface of the vibrating screen after polishing.

3. Identification of chemical potions
Different materials of stainless steel can be quickly distinguished through chemical potions. Specific usage methods:
Put 1~2 drops of stainless steel identification liquid on the material to be tested, wait for a few seconds, the display effect: (such as stains on the surface of the stainless steel, and the coating must be cleaned before testing)
1) 201 stainless steel, the droplet instantly turns dark brown red;
2) 304 stainless steel, droplets do not change color within 3-5 minutes.

Step 1: Look the appearance and craftsmanship of the equipment and machinery.
Generally speaking, from the exquisite appearance, workmanship, etc., you can see the effort made during the production and polishing, and it can also reflect the manufacturer's processing level from the side.

Step 2: is to understand the performance of the device.
Regarding performance, it is generally only after trying it to know how the equipment is. In order to let customers see the performance of the equipment more directly, our Xinxiang DaYong can let customers mail materials and try the machine free of charge. The main thing is to see whether the accuracy of the machine meets the requirements and whether it is convenient to operate, it depends on the specific situation of the customer.

Step 3: Be sure to understand the equipment quality assurance issues clearly. For machinery and equipment, its warranty period is very important. The longer the warranty period, the more confident the manufacturer is in the quality of its products. The brief description indicates that there is no problem with the product quality.

Step 4: Look at the packaging.
To look at the packaging is to see if the things carried with the machine are comprehensive. Many manufacturers just pack the machine and ship it without instructions or anything. Professional manufacturers are fully equipped for these.

In the flour and instant noodle industries, the vibrating screen is mostly used for impurity removal and loosening. The direct-row sieve is often used, and the direct-row sieve is directly discharged. The output is large and it is easy to cooperate with the upper and lower processes. 1000mm type sieve machine with 12 meshes is used for screening and removing loose wheat flour when making instant noodles, which can reach 350Kg/150 seconds. There are also cases where rotary vibrating screens and linear screens are used. The material of the screen machine is generally required to be made of 304 stainless steel for the part in contact with the material, and some are made of all stainless steel.

1. When selecting the ultrasonic vibrating screen model, choose a manufacturer with guaranteed quality and large scale of operation to avoid abnormal heat generation in the later period.

2. When selecting the ultrasonic vibrating screen model, the specific model should be selected according to the actual use requirements and working environment, so as to avoid the phenomenon of abnormal heating of the equipment due to improper model selection in the later use.

3. When using the ultrasonic vibrating screen, the operator is required to strictly follow the operating process, and it must be resolved in time after the abnormal heating of the equipment is found.

4. After using the ultrasonic vibrating screen model, it is necessary to clean the surface of the equipment in time, and also to clean up the residue on the screen surface in time, and pay attention not to let powder and other sundries enter the converter of the equipment.

5. Regularly maintain and maintain the ultrasonic vibrating screen model, check the operating status of the equipment at any time, and check whether the sealing ring and cable of the ultrasonic vibrating screen are aging to ensure that it will not generate abnormal heat due to the phenomenon.

1. Suitable for 0.5 mesh-32 mesh quartz sand vibrating screen: its screen machine is a linear screen, which is characterized by simple structure, low energy consumption, large output, and can simultaneously carry out multi-layer screening without mixing or stringing.

2. Suitable for 10-80-80 mesh quartz sand vibrating screen: its screen machine is a swing screen, which is characterized by high screening accuracy, and the output is 1-5 times that of ordinary circular vibrating screens, and it is fully sealed and designed to effectively prevent dust.

Quartz sand vibrating screen above 3.00 mesh: Its screen machine is an ultrasonic vibrating screen, which is characterized by high screening accuracy and can effectively screen quartz sand powder, etc., to ensure that the equipment will not be blocked, adsorbed, or sticky Internet and other situations. In addition, the whole machine adopts a sealed design to ensure that the powder will not splash, and the later maintenance is also simple and convenient.
