Sieve theory extension zhenyuan Feeding equipment distributor

Sieve theory extension screening distributor1, high screening efficiency, slot area is similar roller sieve seam above 10 times.2, uniform cloth, two forced cloth to ensure that the material into the crusher is a waterfall.3, the material is not required, including high water and slime had no requirements, no blocking device.4, forced removal of iron, to ensure the safe operation of the subsequent crusher.5, a machine in reality more than two qualified particle size sieving.6, forced sinusoidal wave conveyor, not plugging material. The Zhenyuan Mining vibrating screensurface conveying speed is greater than the incoming velocity. (completely solved the vibration sieve, bar Zhenyuan coal crushing plant, banana screen, screen plugging materials)7, to reduce the motor power greatly. The same sort of roller screen power consumption compared to save more than 30%.8, compact structure, convenient installation, simple maintenance, modification, replacement parts are not limited to the control of manufacturers.

Screening machine

Screening machine (sifter) screening machine using the relative motion of granular materials and screen surface, so that part of the particles through the sieve, the sand, gravel, crushed stone and other materials into different levels according to the particle size of vibration Linear vibrating screenequipment.Screening depends on the particle level screen surface, sub-surface grate sieve, sieve and sieve plate three. Grate suitable for screening large particulate material, grate gap is undersize 1.1 to 1.2 times the diameter, generally not less than 50 mm. Sieve plate punched from sheet, circular holes, square or rectangular aperture is generally 10 to 80 mm, long life, easy to plug for mining vibrating screenthe medium particles. Woven wire mesh or welded into the hole was a square, rectangular or elongated, generally used pore diameter is 6 to 85 mm, the mesh strip adapted to wet screening material, mesh is the advantage compared to the effective area large.

Screening machine

Vibrating screen with eccentric annular movable sieve, inertia vibrating screen and resonance screen, their common characteristic is the screen surface for high frequency, small amplitude of vibration, so that the screen material segregation. The mesh is not easy to be blocked, high screening efficiency, simple structure, light weight, low power consumption, but also sieving viscous or wet material, wide application; when the clay, silt or other impurities in raw materials, but also water flushing pressure on the screen, by wet sieving. The amplitude of the moving sieve eccentric ring not changed much screen material, suitable for the first screen. Screen size is generally 13 ~ 100 mm, up to 100 ~ 250 mm. Max feeding size up to300 mm. The inertia vibrating Sand vibrating screen with uniaxial and biaxial vibration system, the motion and material weight and spring stiffness, so the screen surface material or directly affect the amplitude, suitable for feeding quantity and size change is not the occasion, second screening is used to aggregate. The mesh size of 0.5 ~ 100 mm, maximum feed particle size between 100 to 500 mm. The resonance of Linear vibrating screen box is in a resonance condition, only supply overcome screening motion damping energy can work continuously, little power consumption. Suitable for fine stone, screening. The mesh size of 0.5 ~ 80 mm, maximum aggregate diameter 100 mm.Screening test can determine the size of coal in the yield and ash, sulfur, moisture, heat and other quality indicators, in determining the level and quality of screening, screening test data is the main reference. But Coal vibrating screen test data only is the theoretical value, the yield and quality of the actual screening level differs from the. This is not only into the sieve coal samples and the actual coal particle size characteristics are not consistent, there are efficiency screening.
