Particle screening machineBy using the eccentric blocks at both ends of the vibration motor, the rated excitation force is generated, and the transverse excitation forces cancel each other out. The longitudinal excitation force is transmitted to the entire screen surface through the sensing body, causing the material on the screen surface to jump in a straight line towards the discharge port direction under its excitation force. The material smaller than the screen hole falls to the lower layer and flows out through the outlet. After being classified by the linear vibration screen, the screening process is rationalized by reasonably matching the screen mesh, and several different particle sizes of materials are obtained to complete the screening operation of the entire material.

Below, the editor will briefly introduce the operating precautions and screen replacement steps of the particle screening machine, as follows:

　　Precautions for operation:

1. During the transportation process of the linear vibrating screen, in order to increase its rigidity and strength, transportation supports will be added. Users must remove the transportation supports before starting up, otherwise it will affect the vibration operation of the vibrating screen machine and even cause damage to the machine in severe cases.

2. The linear vibrating screen frame is made of wood with minimal deformation, used to maintain the flatness and tension of the screen to achieve normal screening. If the specific gravity is high or the output is large, a metal screen frame can be used in the machine, and you need to pay attention to checking whether the screen is flat.

3. Although the bottom seat of the linear vibrating screen is firm, in order to ensure the balance of the screen body, it is necessary to use bolts to firmly fix the machine base, so that the height difference between the front and rear support seats on the same side is consistent, and the support seat plates on both sides of the same end (feeding end or discharging end) are in the same horizontal plane, with an error of within 2mm, that is, the linear vibrating screen is in a horizontal state.

4. After turning on the machine, pay attention to the trajectory of the materials and adjust the running trajectory to the desired state according to the screened materials.

5. The connection of each part of the linear vibrating screen machine must be firm and reliable, and all bolts must not be loose. There must be no abnormal noise from any components. The small gap between the vibrating part on the screen machine and the surrounding fixed objects should be 30-50mm. Check whether the tie ring screws of the machine frame are locked.

6. Plastic particle screening machines are generally three-phase electric, and the power supply must be connected correctly. It is strictly prohibited to operate without phase.

　　Steps for changing the mesh of the particle screening machine:

1、 Ordinary linear vibrating screens are mostly made of wooden mesh. To replace the mesh, we first remove the wooden screen frame from the screen box.

2、 Use its nail hammer to lift out the nail that fixes the sieve mesh

3、 Lay the newly purchased mesh flat in the middle of the two layers of grid structure

4、 Then use the prepared new nails and nail them into the wooden sieve frame in a different place.

5、 Then put the sieve frame into the sieve box and fix it securely.
