Reasons and solutions for the breakage of the vibrating screen

The more likely the linear vibrating screen is to appear in various faults during operation, the cracking of the screen plate and the breakage of the beam after the vibrating screen has been used for a long time, it is necessary to find the “cause” of the problem. During the use of the vibrating screen, the correctness of the operation method and the importance of regular cleaning and maintenance usually avoid the occurrence of the vibration screen failure frequency.
Vibrating screens are designed to bring efficient results to the production process. The selection of the material of the vibrating screen itself; the calculation of the vibrating motor; the selection of the screen; whether the structural design of the fuselage conforms to the work on site, can select high-quality screening equipment with high efficiency and precision. So find out the cause of the failure and try to avoid such time. Here are a few reasons and solutions.

The cause of the failure: the screen machine caused by the side plate of the screen box is not thick enough or the beam diameter is too small, which can not adapt to the harsh production environment and cracking.

Solution: Find the main force point, strengthen the ribs near the exciter, and install the ribs near the four support feet to strengthen the strength of the screen side panels.

The cause of the failure: the yaw of the vibrating screen causes the sieve plate to crack.

Solution: The unbalance of the support feet, the failure of the shaker or the inconsistent force will cause the screen to crack. Check the blanking situation and periodically measure the height of the support foot damping spring to ensure the balance of the support feet. Regularly screen each part to ensure that the equipment is not faulty, and when lubricating, each of the exciter bearings is quantitatively lubricated to ensure that the resistance of the vibrator in each exciter is generally the same, ensuring that the vibration trajectory is normal.

Cause of failure: The vibrating screen generates resonance, causing cracking failure.

Solution: Improve the vibrating screen surface support ribs, increase the number of intermediate support ribs in the screen, and each one is consistent with the middle one. It has the function of installing fixing bolts, and is pressed by multiple pressure plates to ensure reliable fixing of the screen. , unable to reach resonance.

Cause of failure: Reconstruction measures for equipment failure caused by production load.

Solution: The material is very viscous and difficult to screen, resulting in the proper size of the upper layer material, and the actual load exceeds the rated load of the equipment, causing failure. The inclination angle of the vibrating screen can be appropriately increased to increase the sliding speed under the screen surface and reduce the thickness.

Linear or circular vibrating screen, what is the difference

Circular vibrating screens and linear vibrating screens are common screening equipment in industrial production. However, their working principle is different from that of suitable materials. When selecting vibrating screens, according to the type of materials to be screened, The particle size is chosen to suit the vibrating screen. If a large volume is required, but a circular vibrating screen is selected, the result will not be as expected. First, the characteristics and working principle of the two screening equipment are analyzed. Linear motion vibrating screen working principle When the linear vibrating screen is working, the trajectory of any point on the screen box is a straight line, that is, when the eccentric block rotates, only one force is generated in a certain direction. Then the vibrating screen only performs a linear motion of the plane reciprocating in this direction. The…

Vibrating sieve shakers manufacturer direct sales

The vibrating sieve is a screening device developed to solve the deep screening of wet adhesive materials. Especially for the screening of wet adhesive materials of less than 10 mm, the screen blocking problem is better solved. The vibrating sieve is suitable for industries such as coal classification, electric power, metallurgy (granular classification). The vibrating screen is mainly divided into the linear vibrating screen, the circular vibrating screen, and a high-frequency screen.  The single-axis vibrating screen uses a single unbalanced heavy excitation to vibrate the screen box, and the screen surface is inclined. The moving track of the screen box is generally circular or elliptical. The two-axis vibrating shaker is a double unbalanced heavy excitation using synchronous counter-rotating, the screen surface is horizontally inclined or inclined, and the movement path of the screen box is a straight line. It has an inertial screener, an eccentric shaker, a self-centering…

trommel screen for coal washing

Coal vibrating screen models

In the process of coal treatment, screening operations are often used to classify the size of the coal for the next industrial production. There are a variety of coal screening machine models, the most common being round vibrating screens, heavy duty linear vibrating screens and trommel screens. The drum screen is a common vibrating screen for coal. It has a wide application range and high-cost performance. It can be used for screening coal. However, the coal industry generally requires large output and high efficiency. Compared with mining circular vibrating screens and heavy-duty linear vibrating screens, the drum screen is not too large for coal, and the output is limited. Circular vibrating screen and linear vibrating screen have special advantages in screening coal and ore materials. The output is large and the efficiency is high, which is especially suitable for use in…

Iron ore washing plant with good cleaning effect

Use of iron ore washing plant Washing is the gravity dressing process used to treat ore that is cemented with clay or contains much mud. Mainly the process of separating materials by particle size. The whole process of iron ore washing is generally water immersion, rinsing and mechanical agitation, dissociating the cemented nuggets and separating them from the clay. Washing can be done as a stand-alone operation. For example, some hematite or brown iron ore with a severe slope or residual slope oxidation has very little iron-bearing minerals in the cement clay and is discarded as the final tailings after washing, and the obtained ore can be obtained. Applied as a final product. Iron or manganese ore with higher grades can be used directly for smelting by simply washing the slime. The most common application for washing is as a…
