Stainless steel straight-discharge screen

Stainless steel straight-discharge screen is an efficient and fast screening device, specially used for screening, filtering and impurity removal of powders, particles and slurries. Due to its straight-discharge design, it is particularly suitable for large flow and high-precision screening, and is widely used in food, chemical, pharmaceutical, metallurgy, plastics, ceramics and other industries.

Applicable materials for stainless steel straight-discharge screen

① Powdered materials: flour, milk powder, vitamin powder, medicine powder, chemical pigments.

② Granular materials: sugar granules, salt granules, plastic granules, small nuts, Chinese medicine granules.

③ Lightweight materials: starch, rice flour, puffed food crumbs.

④ Sticky materials: wet powder or lightly sticky materials that require special treatment (such as adding a vibrating screen cleaning device).

What is the working principle of stainless steel straight-discarge screen?

① Motor drive: using dual vibration motors to drive the material to jump on the screen through the excitation force

② Straight discharge: after the material is separated by the screen, it is directly discharged from the bottom of the screen

③ High-efficiency screening: different mesh screens can be selected according to needs to screen out impurities and grade materials at the same time

④ Anti-blocking net design: optional ultrasonic vibration system or bouncing ball device to prevent powder from clogging the screen holes

What are the advantages of stainless steel straight-discharge screens?

1. Reduce material residue: The screen body of stainless steel straight-discharge screen adopts an inclined design, and the discharge port is located at the lower end of the screen body. The material can be quickly discharged from the screen body under the action of gravity, reducing the residue of the material in the screen body. The inclination angle of the screen body is generally between 5°-15°, which can be adjusted according to the fluidity of the material.

2. Avoid material blockage: A scraper is set inside the screen body, which can scrape the material on the screen surface in time and push it to the discharge port to ensure that the material can be quickly and thoroughly discharged from the screen body. For some materials with high viscosity and easy accumulation, a spiral discharger can be installed at the discharge port to avoid material blockage and residue at the discharge port.

3. Handle differences in material characteristics: The particle size, humidity, viscosity and other characteristics of different materials vary greatly, and the requirements for screening equipment are also different. stainless steel straight-discharge screen has strong adaptability and can adapt to different materials by adjusting parameters and replacing the screen. It can be customized according to customer needs to meet specific screening requirements.

4. Solve the problem of poor material fluidity: The in-line design of stainless steel straight-discharge screen allows the material to pass through the screen quickly, increasing the processing capacity. By adjusting the parameters of the vibration motor, optimizing the vibration frequency and amplitude, the screening efficiency can be improved. Select the appropriate screen according to the material characteristics to ensure screening accuracy and efficiency.

What industries use stainless steel straight-discharge screens?

1. Screening of foreign matter in flour production to improve product quality

Stainless steel straight-discharge screen (40-80 mesh) is used for rapid screening before flour packaging to remove foreign matter and ensure purity. Straight-discharge structure, high output (up to 5 tons/hour), food-grade 304/316L stainless steel, in line with GMP standards.

2. Screening of pharmaceutical powder to improve dissolution effect

Vitamin C, vitamin B and other powdered pharmaceutical raw materials are prone to agglomeration and need to be screened to ensure uniform particles. Stainless steel straight-discharge screen uses 200-300 mesh stainless steel straight-discharge screen to remove agglomerates, improve powder quality and prevent screen clogging

3. Screening of plastic particles to improve product purity

After plastic granulation, unqualified particles need to be separated to improve product uniformity. Use straight-discharge screen (4-20 mesh) to ensure that the size of plastic particles is consistent. Wear-resistant screen, suitable for the plastic industry, large flow processing, and improved production efficiency

4. Screening of metal powder to ensure uniform powder particle size

Metal powders (such as aluminum powder, iron powder, copper powder) need to be finely screened before 3D printing and smelting. Ultra-fine stainless steel straight-discharge screen (200-400 mesh) and high-precision screen are used to ensure the stability of metal powder particle size.

5. Screening of ceramic powders to reduce product defects

Ceramic powders need to control particle size before sintering to avoid cracks or unevenness in the finished product. Use stainless steel straight-discharge screen (100-325 mesh) to grade ceramic powders and improve the yield. It has high screening accuracy and is suitable for ceramic raw materials such as kaolin and alumina.
