When the vibrating screen is running, the material deviation occurs. How to deal with it? 7 major reasons tell you

　　Anyone who knows the vibrating screen knows that the linear vibrating screen uses the vibrating motor as the vibration source, so that the material is thrown up on the screen and moves forward in a straight line, and the material enters the feeding port of the screening machine evenly from the feeder. Several kinds of sieves and sieves are produced through a multi-layer screen and are respectively removed from the respective outlets. In the operation of the linear screen, material deviation is a common problem, but there are still many people who do not know how to solve it. 

　　1. Improper installation of vibration motor

　　Since the linear vibrating screen transports the material through the vibrating body, that is, the vibrating motor pushes the material with a fixed thrust of a fixed size in a fixed direction. Therefore, when there is a poor conveying condition, basically It can be judged that there is a problem in the installation angle of the vibration motor.

　　2. The equipment has a large workload and long running time.

　　Whether it is human or equipment, the amount of work that can be carried out every day has a certain limit. Those who work for a long time will be exhausted or even sick, and the equipment will malfunction. Compared with the large linear vibrating screen, due to its heavy weight, if it is combined with large-scale screening labor for many years, some parts of the body will loosen due to such long-term repeated vibration and strong inertia. Therefore, the angle of the vibration motor may be changed, and the material may be deflected.

　　3. Uniform feeding without requirements

　　The requirements of the linear vibrating screen are repeatedly mentioned: uniform feeding. Because if the feeding time is too much, it is easy to cause the screening accuracy to be unstable, and the material bias is large due to the material, and the discharge is biased to one side.

　　4. The damper springs and other parts of the screen body are aging and loose.

　　In addition to the vibration motor to provide the main source of screening power for the linear vibrating screen, the linear vibrating screen damping spring, bouncing ball, sealing rubber ring, etc., which are present due to vibration damping, affect the vibrating force and straight line more or less. The water of the vibrating screen body is stable.

　　If a certain component has problems such as aging, it will cause the problem of deviation of the discharge direction due to the instability of the screen of the linear vibrating screen, and even the sudden abnormal noise and the serious life of the linear vibrating screen will be greatly reduced. And other issues. Therefore, it is necessary to carry out regular inspection and maintenance of the equipment, and the materials used for the parts are also essential.

　　5. The position of the center of gravity of the linear screen itself is unstable or the position of the eccentric block of the motor is not balanced.

　　Nowadays, due to fierce competition and oversaturated market, the market of vibrating screen equipment is prone to chaos in the market. Some people choose to pay low price, and it is inevitable that some black-hearted manufacturers will take advantage of the inferior imitation linear vibrating screen at abnormal market prices, although the appearance is not the same. Second, but there is no technical content, so you must polish your eyes when purchasing equipment, and buy equipment from regular manufacturers.

　　6. Damping springs have different materials and different stiffness

　　The same is the quality problem of the old-fashioned, the importance of the shock-absorbing spring to the linear vibrating screen is no less than that of the vibrating motor. He plays an important role in maintaining the stability of the linear vibrating screen and prolonging the life of the linear vibrating screen. Many prices are much lower than the price. Manufacturers with normal sales prices rely on accessories and consumables to cut corners to attract customers, which ultimately leads to heavy losses for some customers.

　　7. Screen box deformation

　　The sieve box refers to a sieve surface which is fixed above the vibration motor and below the feed port and which is fixed by the screen frame and the periphery thereof. Under the normal operation of the linear vibrating screen, especially the large-scale, high-frequency linear vibrating screen, the screen frame needs the strong excitation force of the gravity and vibration motor from the large-scale screening material at the same time. If the strength is not enough, it is easy to be deformed. Damaged problem. The strength of the screen box depends mainly on the manufacturer's material selection, welding process, and additional robust design.

　　In the case of material deviation in production, you can find out the root cause of the fault and the corresponding solution according to the above seven reasons. In addition, in daily production, you should be familiar with the working principle, performance and common fault phenomena of the vibrating screen, operate correctly, and do routine maintenance to reduce the failure rate and improve work efficiency.
