How to choose between linear vibrating screen and rotary vibrating screen?

For purchasers who don't know much about vibrating screens, they often worry about whether to choose a linear vibrating screen or a rotary vibrating screen. Which device is more suitable? Xinxiang Tianteng Vibration Machinery Co., Ltd. shares some knowledge in this regard with you based on its many years of experience. In fact, as screening equipment, the linear vibrating screen and the rotary vibrating screen are quite different in appearance and working principle. First, the screening principles are different. The rotary vibrating screen uses an upright motor as the excitation source. Eccentric weights are installed at the upper and lower ends of the motor to convert the motor's rotational motion into horizontal, vertical, and inclined three-dimensional motion, and then transmit this motion to the screen surface. The linear vibrating screen is driven by dual vibration motors. When the two vibration motors rotate synchronously and in opposite directions, the exciting forces generated by their eccentric blocks offset each other in the direction parallel to the motor axis, and overlap into a resultant force in the direction perpendicular to the motor axis, so the motion trajectory of the screen machine is a straight line. The two motor shafts have an inclination angle relative to the screen surface in the vertical direction. Under the combined force of the excitation force and the self-weight of the material, the material is thrown up and jumps or moves forward in a straight line on the screen surface, thereby achieving the purpose of screening and grading the material. Second, the discharge particle size is different. The linear vibrating screen is suitable for screening various dry powdered or granular materials with a particle size of 0.074-5mm, a water content of less than 7%, and no stickiness. The feed particle size is not greater than 10mm. The rotary vibrating screen can screen 0-400 mesh, whether it is liquid or slurry 0-600 mesh can be filtered. Third, the investment cost is different. For users, the quotation of screening equipment is also a key factor to consider. Generally, the quotation of the rotary vibrating screen is lower than that of the linear vibrating screen. The two equipment models are complete and can be customized. In addition to the above differences, users should also consider it according to the materials they process. For example, when processing flour, Chinese medicine granules and other materials with a hardness below the medium level, you can choose a rotary vibrating screen for flour and a linear vibrating screen for Chinese medicine granules. In general, linear vibrating screens and rotary vibrating screens have their own advantages and disadvantages. Users can refer to the above analysis for consideration.
