Trommel screen has simple structure, low energy consumption and good sealing performance, which can effectively prevent dust raising phenomenon. The operation is stable with low noise and small footprint, and sieving efficiency is as high as 95% above. Flexible feeding method can be adopted according to the actual situation, and trommel screen is easy and convenient to carry out daily maintenance. By using the rotary screen method, the material in the drum is constantly turned and rolled, which effectively reduce the material blocking situation, and the machine failure rate is reduced. The trommel screen is used for grading and screening of medium and fine materials. It can be used for grading large and small stones in the stone field and separating the soil and stone powder outside the stone. The trommel screen can be used to separate sand and stone in quarry plant. In chemical industry and coal industry, trommel screen is used to screen bulk and powder materials. The application scope is very wide, the working environment requirements are low, and can be customized according to different material requirements of different models and specifications of the trommel screen , so as to meet different production needs. Linear vibrating screen uses vibration motor excitation as vibration source, so that the material is thrown on the screen, and at the same time do straight forward motion, the material from the feeder into the feeding inlet of the screen, through the multi-layer screen to produce several specifications of the material above the screen and the material below the screen, then respectively discharge from their outlets. the trommel screen has characteristics of low energy consumption, high output, simple structure, easy maintenance, fully closed structure, no dust spill, automatic discharge, and which is more suitable for assembly line operation.
The linear vibrating screen is driven by a double vibration motor. When two vibration motors do synchronous rotation, the excitation force generated by the eccentric blocks cancel each other in the direction parallel to the motor axis, and change into one force in the direction perpendicular to the motor axis, so the motion trajectory of the linear vibrating screen is a straight line. The two motor shafts have a dip Angle relative to the screen surface. Under the combined action of excitation force and self-gravity, the material is thrown up on the screen surface and moves forward in a straight line by jumping, so as to achieve the purpose of screening and classifying the material. Linear vibrating screen is widely used in chemical industry, food, plastics, medicine, metallurgy, glass, building materials, grain, fertilizer, abrasive, ceramics and other industries for dry powder or granular material screening.
