It took about 200 hours, and the perforated plate had to be replaced frequently, which was extremely troublesome. Rubber perforated plates may have a longer lifespan than metal ones in some cases, but they are useful when sifting iron ore with many sharp edges,
When a high load is applied to the perforated plate, it has a short lifespan, similar to metal plates. Additionally, rubber perforated plates have the disadvantage of being sensitive to heat, making them unsuitable for sieving iron ore, which normally has heat.

Although ceramic tiles are bonded to the rubber layer, adjacent ceramic tiles are not bonded to each other, so when sorting, the ceramic tiles may vibrate individually, and the impact is absorbed by the rubber layer as a cushion layer. Since the tiles can be individually absorbed, the strength of the perforated plate is also guaranteed.
