The size of the catalyst particles has a direct impact on the capacity of the catalyst. In order to keep the catalytic performance of industrial catalysts efficient and consistent, catalyst manufacturers need to unify and control the particle size of the finished catalyst products according to customer needs. This is the catalyst vibration.

Catalysts can transform raw materials into high value-added chemical products and fuels in an efficient, green and economical manner. They are widely used in various fields such as chemical industry, energy, electronics and so on. Therefore, these commonly used catalysts are also called industrial catalyst. There are various types of catalysts and catalytic reaction principles in industrial catalysts. The indicators that determine their catalytic performance are: activity, strength, loss on ignition, abrasion, and screening rate. The sieving index is worth the particle size of the industrial catalyst, that is, the mesh number. The mesh control of industrial catalysts must rely on the screening action of the catalyst vibrating screen.

Detailed introduction of catalyst shaker

The mesh number of the catalyst does not directly affect the activity of the catalyst, but the size of the catalyst particles will directly affect the contact and diffusion of the reactants, that is, the diffusion performance of the products and reactants, and the mass and heat transfer of the reaction. Controls reaction speed and path to a certain extent. Therefore, the smaller the particle size of a catalyst of the same quality, the stronger the capacity of the catalyst. In order to keep the catalytic performance of industrial catalysts efficient and consistent, catalyst manufacturers need to unify and control the particle size of the finished catalyst products according to customer needs. This is the necessity of the application of catalyst shakers in their production processes.

Selection of catalyst shaker

According to customers from the industrial catalyst industry, the mesh size of the catalyst generally has a strong correlation with the diameter of the reaction tube, and the mesh size of the catalyst used should be determined on the basis of avoiding internal and external diffusion. The diameter of common reaction tubes is about 10mm, and the number of catalysts used under these conditions is mostly 20-40 mesh.

Therefore, the shaker manufacturer (Jinhe Machinery) recommends using a linear shaker as a prototype to customize the production of industrial catalyst shakers. .

As for the material, since the catalyst is chemically active, it is recommended to use high-quality 304 stainless steel with relatively stable chemical properties as the main material of the catalyst vibrating screen. As for the low-pass support, considering the cost factor, ordinary carbon steel can be used. The size of the model is customized according to the needs of the customer's sieve size.

Vibrating screen feeder helps to improve the screening effect of catalyst vibrating screen

If the customer's sieve volume is relatively large, the single feed volume is also large. Considering that the screening accuracy of the catalyst vibrating screen is improved on the basis of meeting the customer's required processing volume, avoiding mixing stages and sieving due to excessive single feed volume. Vibration screen manufacturers (Jinhe Machinery) suggest that vibration screen separators can be installed at the equipment inlet.

分料器。 The vibrating screen feeder is a device installed on the vibrating screen to uniformly distribute the screened materials. Since this feeder is mainly used on a linear vibrating screen, it is also called a linear vibrating screen feeder. In order to be able to quickly and conveniently distribute the screened materials evenly on the screen surface, the installation position of the linear screen feeder is mainly at the feeding inlet of the equipment.

According to different types of materials and different screening requirements, there are different types of vibrating screen feeders. According to different appearances, they can be divided into three types: "eight" or "one" vibrating screeners. , Gate-type linear sieve feeder, umbrella-type vibrating sieve feeder. The "eight" or "one" type vibrating screen divider is the traditional form of the divider. When the input volume is not large and the output is not high, the straight-line sieve outlet is often installed with this divider. , But once the input volume is too large, it is difficult to achieve the expected material distribution.

The gate type linear sieve divider is an improvement on the basis of the traditional divider, which is based on the principle of the sluice when the dam is flooded, that is, the traditional divider and the inlet One or more baffle devices are added in between to achieve the purpose of further controlling the amount and distribution of the materials entering the sieve through the gate. Even the largest amount of material can play a good role in distributing materials.

Umbrella-type vibrating screen feeder is based on the outline features of the umbrella. The bin of the feeder is designed in the shape of an arch in the middle, which can reduce the impact force of the screen and control the amount of feed, while reducing the pertinence. The centralized distribution of the material in the middle of the screen reduces the damage rate of the middle of the screen, which is most prone to relaxation and breakage.
