Screening Plant Selection Notes

Screening machine using the relative movement of granular materials with the screen surface, so that part of the particles through the sieve, sand, gravel, crushed stone and other materials by particle size into different levels of vibration screening machinery and equipment. Screening level depends on the particle surface sieve, sieve surface points grate plate mesh sieve and three. Grate material suitable for screening large particles, grate gap is under the screen size of 1.1 to 1.2 times, usually not less than 50 mm. Sieve plate formed by punching steel plate, holes were round, square or rectangular aperture is generally 10 to 80 mm, long service life, easy to plug, suitable for screening the medium particles. Compiled by a wire mesh screen or welded into the hole was a square, rectangular or elongated, common aperture is generally 6 to 85 mm, a long strip suitable for screening wet sieve materials, the advantages of the mesh screen is relatively effective area great.

1, A sieve of use: what materials screening? Screening or screening coal washed coal, ores, chemicals, food, etc., is graded or dehydration, referral, off mud.2, the material is wet or dry material sieve material (moisture content is the number), select sporty and tilt the screen surface large volume of water or when the material viscosity.3, the screening machine installation space dimensions: the screen surface width B and length L and height H4, selection and screening equipment classification: a fixed screen surface; 2, vibrating screen surface; 3, movement screen surface; 4, drum sieve surface; 5, other types of screen surface and so on.5. The maximum feed size, the expected size.6, the screening plant interface devices, and what follow-up equipment and size? The need for transport function, functional fabrics and iron functions.7, equipment handling capacity t / h.8, the installation forms: pedestal or hanging; motor is left or right mounting installation.9, the electronic control box and the control linkage installation sequence. Motor, electric control selection requirements.10. Other special requirements: the screen surface inclination, screens and other exterior paint colors
