Sieve plates are mostly used in chemical industry and coal manufacturing, and can be divided into many types according to their shapes, and their main functions are also different. Long-hole sieve plate, one of the sieve plate types, is mostly used for sound insulation, which can be seen in KTV rooms and road sound insulation. And its materials are also divided into polyurethane elastomer sieve plate, stainless steel sieve plate and ordinary sieve plate. What is the manufacturing process of long-hole sieve plate? What are the precautions?

Tools/raw materials

Slotted screen

Pressure screen cylinder

Steps/methods

1, the motor should be fastened on the installation surface, which must be smooth and flat. The motor can be installed horizontally. ? YZ-500V four-core rubber cable is used as the motor lead. When the power supply is connected, the outgoing cable is not allowed to bend sharply and is reliably fixed with the vibrator.

2, the motor should have reliable grounding, the motor has a grounding device, the lead end is marked, and solid bolts can also be used for grounding.

3. Ensure that the clearance between the screen box and non-moving parts such as hopper and chute should be at least 75mm ... When the equipment is installed according to the installation drawing, the foundation should have sufficient rigidity and strength to support all dynamic and static loads of the vibrating screen.

4. Before starting the screening machine, check whether there are obstacles around the screening machine and whether the connecting bolts are tightened everywhere, especially the fixing bolts of the vibration motor, the support seat and the sieve plate should be tightened again.

5. Check whether the steering of two vibration motors or vibration exciter is opposite. If the steering direction is the same, change the power wiring of one motor so that the steering directions of the two motors are opposite.

6. After continuous operation for 4 hours, measure the bearing temperature, which shall not exceed 75℃. Stop feeding before the screen machine stops, and then stop after the screen material is gone.

7. After parking, clear the materials and sundries on the screen surface in time. The vibration motor or exciter should be refueled once after three months of use, with minor repairs once every six months and major repairs once a year.

Matters needing attention

When operating the hydraulic punching machine, first check whether the punch and die of the mechanical punching machine match, and the machine needs to choose the punch and die that match the aperture, otherwise it will damage the main machine of the punching machine.

Secondly, before stamping, insert the workpiece into the die head and opening of the mechanical punching machine, align with the scribe line, and the die must be rotated and pressed first. Finally, shake the handle to press the punch down, and you can punch out the hole.

If any abnormal fault is found in any link of operation, the stamping should be stopped immediately to eliminate the fault, so as not to damage the parts. Pay attention to the lubrication of screw and nut before and after operation.

Making long-hole sieve plate is a complicated matter, so we should pay attention to the details, otherwise it will cause some defects of the product, which can be completed with the help of professionals. Stainless steel sieve plate is the best material with strong corrosion resistance, and its service life is one to two times that of other sieve plates. However, due to its high price, most people choose polyurethane elastomer sieve plate, and its superior wear resistance is another reason why people choose it. The market demand of sieve plate is extensive and the prospect is very considerable.
