When two vibrating motors installed longitudinally on the screen body run relative to each other, the horizontal excitation forces generated by them cancel each other out due to the relative operation of the motors, and the longitudinal excitation force is transmitted to the entire screen box through the vibration transmission body. The screen surface is vibrated, so that the materials on the screen surface are subject to the excitation force and jump on the screen surface in the direction of the discharged product. The materials smaller than the screen hole fall to the lower layer through the screen hole, and then jump from The discharge port flows out. Due to the reasonable screening process, after the materials are classified by the vibrating screen, several materials with different particle sizes can be obtained to complete the material classification operation.

From the point of view of the trajectory of the screen box, which is the screen box, the square swing screen is also called the arc screen. The vibration force generated by the drive device is an inertial force that changes in a certain direction around a fixed axis, and its essence is The reciprocating inertial force formed by the rotation of the eccentric wheel around the fixed axis. According to the structural characteristics and working principle of the square rocking vibrating screen, the screen surface is generally horizontal or slightly inclined (the inclination angle is 0°~5°). After the screen machine is started, the shaking body of the screen machine, namely the screen box, will reciprocate back and forth under the action of inertial force. The screen box drives the screen surface to periodically shake, so that the material on the screen surface will move with the screen box in a directional jumping motion. During this period, the physical materials smaller than the screen surface aperture fall to the lower layer through the screen holes and become under-the-screen objects. The materials larger than the screen surface aperture are discharged from the discharge port after continuous tumbling and jumping motion, thereby completing the screening work.

Probability screen is a kind of sieve machinery which can make use of the principle of probabilistic screening. The sieve theory points out that, the stranded time of each object in its interior is opposite to its weight in the work. Through the actual experiment, particle size is much smaller than the hole diameter, it can quickly pass the screen surface, the more close to the hole diameter, the longer the stranded time, if the diameter of the two sides are close, the stranded time of the material is the longest, popular speaking, large particles stay time is long , small particles stay time is short.

The small food flour supply system uses two flour or starch powder supply systems at the same time. It is mainly used for snack foods. The dough mixer automatically quantifies the dough during mixing. The quantification does not take up the dough mixing time, and a quantification cycle is completed in 3 minutes. , the blanking time is 10–20 seconds, and the quantification is accurate.

Use dust-free feeding and vacuum feeder to lift sesame and powdered sugar into the buffer bin, and then lift into the temporary storage bin after weighing. The flour enters the buffer bin and the online weighing bin under positive pressure to achieve sugar weighing 75 kg and 25 kg of sesame into the mixing tank and mix for 5 minutes, then put in 150kg flour, and repeat the operation for 3 minutes.

The system consists of a feeding station, a buffer storage bin, a vacuum feeder, a pulse dust collector, a weighing bin, etc.

The explosion-proof vibrating screen is suitable for screening flammable and explosive materials. The explosion-proof mark is Ex d IIB T4 Gb/Ex tD A21 IP65 T130℃. It is suitable for the food industry, pharmaceutical industry, chemical industry, metal powder industry, lithium battery industry and other industries.
