As a commonly used screening equipment in the mining industry, the vibrating screen is in a long-term working state and the operation is also a fine operation, so there will be more or less problems. If the feeding is too slow, it will affect the screening efficiency of the vibrating screen. The reasons for the slow feeding of the vibrating screen and the adjustment methods have been introduced in detail below. Let’s take a look.
The reason why the vibrating screen feeds slowly
1. Vibration motor problem
(1) The motor power cannot reach or the motor power is normal but the speed is slow, and the 1500 rpm that cannot be used will also cause the feeding to be slow.
(2) The steering problem of the vibration motor: the steering of the motor is divided into two types: forward rotation and reverse rotation. Under normal circumstances, the steering of the two motors is in the opposite direction, but if the user connects the positive and negative poles incorrectly when the power is connected, it will cause When the motor rotates in the same direction, there will be a problem of slow or no material feeding on the screen surface.
(3) The problem of the installation position of the motor: There are three installation positions of the vibrating motor of the linear screen, which are the bottom, the two sides, and the upper part. If the vibration motor is installed close to the feeding port, the screen surface material will run for a certain distance and then the speed will decrease and stay on the screen surface.
2. The amount of screen cloth is too large
The excessive amount of cloth on the screen surface is also the reason for the slow feeding of the vibrating screen. When the screen is added, the load of the motor is also added accordingly, and there will be a problem of slow feeding.
