The linear vibrating screen uses the vibration motor as the vibration source to excite the vibration, causing the materials to be lifted on the screen and move forward in a straight line. The materials are uniformly fed into the feed port of the screening machine from the feeder, and through multiple layers of screens, various specifications of screened materials and undersized materials are produced, which are respectively discharged from their respective outlets. It has low energy consumption, high output, simple structure, easy maintenance, fully enclosed structure, no dust spillage, automatic discharging, and is more suitable for assembly line operations.
Working principle
The linear vibrating screen is driven by two vibration motors. When the two vibration motors rotate synchronously and in opposite directions, the excitation forces generated by the eccentric blocks cancel each other out in the direction parallel to the motor shafts, and combine into a single force in the direction perpendicular to the motor shafts. Therefore, the movement trajectory of the screen is a straight line. . The two motor shafts of this device have an inclination angle relative to the sieve surface. Under the combined force of the excitation force and the gravitational force of the materials, the materials are thrown up and perform a jumping forward linear motion on the sieve surface, thereby achieving the purpose of screening and grading the materials. It can be used to realize automated operations in the production line. It has the characteristics of low energy consumption, high efficiency, simple structure, easy maintenance, and a fully enclosed structure without dust spillage. Highest
The sieve size is 325 mesh. It can separate 7 different particle sizes of materials.
Products features
Excellent materials and hygiene safety
Fully contact surface stainless steel: The entire machine is made of 304 or 316L stainless steel, featuring excellent corrosion resistance, rust prevention, and oxidation resistance capabilities. It completely eliminates the risk of iron ion contamination during the processing of materials.
Compliant with industry standards: The design conforms to GMP, FDA, HACCP, etc. food production standards. The surface undergoes precise polishing treatment (such as Ra ≤ 0.8 μm), which is smooth and has no dead corners. It does not accumulate materials and is extremely easy to clean and disinfect, meeting the requirements of aseptic production.
Pollution-free sealing: Food-grade sealing components such as silicone and polyurethane are used to ensure the sealing performance of the equipment, preventing cross-contamination and dust escape.
Efficient and precise screening performance
Strong linear vibration: Two motors drive to generate the same frequency and opposite excitation forces, forming a single-direction linear motion. The materials are uniformly lifted on the screen and move in a straight line, achieving high screening accuracy and fast processing speed.
Multiple layers of precise classification: It can be configured with 1 to 5 layers of screens, enabling multi-level precise screening or filtration on the same equipment, separating materials of different mesh sizes (usually from 2 mesh to 500 mesh), with high screening efficiency.
Anti-block screen design: Various cleaning devices such as bouncing balls, ultrasonic waves, and rotating brushes (optional) are equipped to effectively prevent screen blockage and ensure continuous operation.
Application fields
Food and health supplement industry: Screening and impurity removal, as well as particle size classification for flour, starch, sugar powder, salt, monosodium glutamate, milk powder, food additives, tea, and nutritional powder.
Pharmaceutical and raw drug industry: Fine screening of traditional Chinese medicine powder, Western drug raw materials, granules, plant extracts, and pharmaceutical intermediates to ensure drug purity and uniformity.
Chemical and new material industry: Screening and filtration of resin powder, pigments, dyes, coatings, lithium battery materials, fine ceramic powder, and high-temperature materials.
Mineral and metallurgy (high-purity field): Precise classification of high-purity quartz sand, abrasives (such as silicon carbide, corundum), and metal powders (such as cobalt powder, nickel powder).
