冲孔筛面一般是在厚5~12mm的钢板上冲制出圆形、方形或长方形筛孔而成

The punching screen surface is generally formed by punching round, square or rectangular screen holes on a steel plate with a thickness of 5 ~ 12mm. Compared with the round or square sieve surface, the rectangular sieve surface usually has a larger effective area, lighter weight, and higher productivity. It is suitable for processing materials with high moisture content, but the accuracy of sieving materials is poor. <br>There should be a certain distance between the sieve holes, so that it can be wear-resistant and can ensure sufficient screen surface strength. The hole distance is generally determined by experience. If the size of the screen hole is 10 ~ 100mm, the hole distance is 1.25 times. The punching screen surface is relatively strong and has a long service life, but the effective area is small, about 40% ~ 60%. Its sieve size is generally 12 ~ 50mm, which is suitable for sieving medium-sized materials.

Punching sieves are generally made from round, square or rectangular sieves on steel plates 5 to 12mm thick. Compared with the sieve surface of round or square sieve, the sieve surface of the rectangular sieve is usually more effective area, light mass and high productivity, which is suitable for handling materials with high moisture content, but the accuracy of the screening material is poor.<br>A certain distance should be maintained between the perforations so that it can be wear-resistant and sufficient sieve strength can be guaranteed. The hole distance is generally determined by experience, if the dimensions of the perforation are 10 to 100mm, then the hole distance is 1.25 times. Punching sieve is relatively strong, long service life, but the effective area is small, about 40% to 60%. Its perforation size is generally 12 to 50mm, suitable for medium particle size material screening.

The punching screen surface is generally formed by punching circular, square or rectangular screen holes on the steel plate with a thickness of 5-12mm. Compared with the circular or square screen, the rectangular screen usually has larger effective area, lighter weight and higher productivity, which is suitable for the treatment of materials with higher moisture content, but the accuracy of screening materials is poor.<br>A certain distance should be kept between the sieve holes, so as to be able to wear-resistant and ensure sufficient screen surface strength. The hole spacing is generally determined by experience. If the size of the sieve hole is 10-100mm, the hole spacing is 1.25 times. The punching screen surface is relatively solid and has a long service life, but the effective area is small, about 40% ~ 60%. The mesh size is generally 12-50mm, which is suitable for medium-sized material screening.
