Working principle: When the two vibrating motors rotate synchronously and reversely, the excitation force generated by their eccentric blocks counteracts each other in the direction parallel to the motor axis, and is superimposed into a resultant force in the direction perpendicular to the motor axis. Therefore, the motion track of the motor is a straight line, and the two motor axes have an inclination angle to the screen surface. Under the combined force of the excitation force and the self-gravity of the material, the material moves forward in a straight line in a jumping manner on the screen surface, So as to achieve the purpose of screening, screening and grading of materials.
The vibration of the vibrating motor is used as the vibration source to make the material be thrown up on the screen and move forward in a straight line. The material evenly enters the feed inlet of the screening machine from the feeder, and generates several specifications of materials on the screen and under the screen through the multi-layer screen, which are discharged from their respective outlets. With low energy consumption, high output, simple structure, easy maintenance, fully closed structure, no dust overflow, automatic discharge, more suitable for assembly line operation.

Yes, rotary vibrating screens can be used to remove impurities from cassava flour. The rotary vibrating screen is a common screening equipment that uses rotation and vibration to screen and separate raw materials on the screen. It can effectively remove impurities in cassava flour, such as wood chips, stones, fibers, etc.

When using a rotary vibrating screen to remove impurities from cassava flour, it is necessary to select an appropriate screen aperture to ensure that the impurities are effectively separated, while the cassava flour remains on top through the screen. According to the characteristics and requirements of cassava flour, selecting the appropriate screen aperture can achieve the removal of impurities of different particle sizes.

At the same time, adjusting the vibration parameters of the rotary vibrating screen, such as vibration frequency and amplitude, can affect the impurity removal effect. Appropriate vibration parameters can improve screening efficiency and separation effects and ensure the purity of cassava flour.

It should be noted that when using a rotary vibrating screen to remove impurities, attention should be paid to the cleaning and maintenance of the equipment, and the screen mesh and screen frame should be cleaned regularly to avoid accumulated tapioca flour and impurities from affecting the screening effect. In addition, operators should strictly follow operating specifications to ensure personal safety.

In summary, the rotary vibrating screen can be used to remove impurities from cassava flour. By selecting the appropriate screen aperture and adjusting the vibration parameters, the impurities in cassava flour can be effectively removed and the quality and purity of cassava flour can be improved.

Explosion-proof vibration motors should generally be cleaned and refueled after 2,000 hours of use. There are two ways to clean bearings:
1. Hot oil cleaning method
Due to long-term use, bearings hardened by soft dry oil or anti-rust paste should be immersed in thermal engine oil at 100-200°C, clamp the bearing with pliers, and use a brush to clean the oil stains on the bearing. Soft dry oil or anti-rust paste melts when heated to 100-200°C and is easily washed out from the gaps in the bearing. Sometimes it is just a matter of shaking the bearing in oil several times. Oil dirt will also flow away from the gaps.
When cleaning the radial spherical bearings of old motors or imported motors, the balls, ball frames, and inner rings should be turned laterally out of the outer ring and then immersed in hot oil. When cleaning short cylindrical roller bearings, the rollers should also be cleaned. , the bead frame, inner ring and outer ring are detached. During hot oil cleaning, the oil temperature should not exceed 20°C.
2. General cleaning method
Soak the bearing in kerosene for 5-10 minutes, hold the inner ring with one hand, and rotate the outer ring with the other hand. The dry oil or anti-rust paste on the bearing will fall off. Then put the bearing into cleaner kerosene, scrub with a soft brush to clean the oil in the balls and gaps, then put it into gasoline to clean it once, take it out and put it on clean paper. When cleaning radial spherical ball bearings and short cylindrical roller bearings, the balls, ball frames, inner rings and outer rings should be separated and cleaned.
The bearings installed on the shaft are mainly cleaned by spraying oil or spraying with an oil gun. The oil stains that are easy to be cleaned are first washed with kerosene and then gasoline; the oil stains that are difficult to be cleaned are first rinsed with 100-200°C hot engine oil. Or spray with an oil gun, and then clean with gasoline. Be careful not to use sharp tools to scrape hardened grease or rust on the bearings to avoid damaging the smoothness of the bearing rolling elements and groove rings. Clean the explosion-proof vibration motor bearings and wipe them dry with a clean cloth.
