Description

Technical Field

[0001] The utility model relates to the technical field of plane rotary screens, in particular to a plane rotary screen for compound fertilizers. Background Art

[0002] The compound fertilizer flat rotary screen is a mechanical equipment specially used for producing and screening compound fertilizers. It consists of a frame, a feeding device, a screen body, a support, a motor and a reducer. The working principle of the compound fertilizer flat rotary screen is to use the motor to drive the screen body to rotate, generate centrifugal force and inertial force inside the screen body, so that the material can obtain a better screening effect. The flat rotary screen may have the problem of spring damage during use. As one of the key components of the flat rotary screen, the spring is subjected to vibration and impact. After long-term use, it may suffer from fatigue fracture or loss of elasticity. After the spring is damaged, the bottom of the screen box will vibrate too much, which is easy to cause damage to other components, and there are certain shortcomings. Utility Model Content
