What Are The Technical Conditions Of Vibrating Screen?

The vibrating screen shall meet the requirements of this standard and be manufactured according to the samples and technical documents approved by the specified procedures.

Structural requirements of vibrating screen

It is convenient to discharge materials and install feeding and discharging equipment.

The movement of materials along the screen surface shall be uniform, and it is not allowed to shift to one side during discharging.

Corresponding screen surface can be installed according to the use.

It is convenient to repair and replace wearing parts.

Prevent dust from entering the bearing and bearing oil leakage.

Convenient for transportation.

right mounting mode.

The screen surface and screen frame shall be fixed reliably.

The welding of metal structures shall meet the requirements of dimensional tolerance accuracy class C, geometric tolerance class G, and welding quality assessment class BS and BK specified in JB/T..

 Overall performance requirements of vibrating screen

The vibrating screen shall operate flexibly and stably without jamming.

 The oil seal shall not leak when the shale shaker is running.

 During the operation of vibrating screen, the normal working temperature rise of bearing shall not exceed 4 ℃, and the maximum temperature shall not exceed  ℃. For imported bearings and lubricants, refer to relevant data.

 The working frequency deviation of vibrating screen shall not exceed ± .%.

 The amplitude difference of the corresponding points of the plates on both sides of the screen box shall not exceed 1% of the calibrated amplitude. Except for FJ type, the amplitude of the discharge end at the same side of the screen box shall not be greater than the amplitude of the feed end, and the difference shall not exceed 1%. The transverse amplitude of screen box shall not exceed .mm.

The vibration direction angle of the vibrating screen shall meet the sample requirements.

For large vibrating screen with screen width greater than mm, the prototype of each specification shall be subject to experimental modal analysis to ensure that the natural frequencies of each order of the structure are far away from the working frequency.

Screen box

..The bent parts (such as side plates, stiffening beams and other components) used in the screen box shall be trimmed before bending, and there shall be no cracks, scars and other defects after bending.

The side plates and crossbeams forming the screen box are generally not allowed to be spliced, especially in the vertical direction.

The side plate of screen box shall be flat, and the flatness tolerance shall not exceed 1mm per square meter.

After the screen box is made, the diagonal limit deviation shall not exceed mm every 1mm (measured at the place where the screen plate is installed).

The length limit deviation of all beams shall not exceed ± .mm.

The parallelism tolerance of the center lines of two adjacent beams shall not exceed 1mm for every 1mm in the length direction of the beam, and shall not exceed 4mm for any two beams.

The surface of the fastened structural members shall be cleaned of iron filings and burrs before fastening. Before tightening the high-strength bolts, the wrench shall be used to pre tighten them, and then the torque wrench shall be used to tighten them to the torque specified in the drawing.
