Span three largest domestic double facade came under the vibrancy gridiron
Vibration Equipment Co., Ltd. of Henan mighty independent research under the three tier facade vibrancy WLZR-40 × 85 heavy-duty line screen in the successful trial run on March 16, June 20 delivery of formal and Brazilian partners. WLZR-40 × 85 line screen is mainly used in heavy industry, metallurgy sintered pellet screening, 4 meters wide, 8.5 meters long, more than 85% screening efficiency, the screening capacity of an 1400t / h or so, is currently span the largest double-line formation under the screen.
2009 3 months, by the mighty Vibration Equipment Co. Ltd. Henan, independent research and development under the three tier facade vibrancy WLZR-40 × 85 line screen for heavy equipment workshop in the mighty test of a successful, on June 20 officially delivery partners in Brazil. The use of a dual-motor vibrating screen drag the axis from the principle of simultaneous linear vibration of high efficiency, low noise, energy saving, the vulnerability of small large-scale screening device, the sieve screen with three boxes facade structure, thin oil lubrication exciter, comb sieve, high torque rotation axis, three-phase asynchronous motor, effectively alleviate the processing efficiency of the previous general low sintering screen, screen surface easy to wear, poor stability.
WLZR-40 × 85 heavy-duty line of innovative screen is reflected in the first, a three-screen box facade structure vibration transmission. The structure is in the wide-body shaker sieve the middle of the center of a plate parallel to the side, the wide screen into two long beams, one end of the same axis line both sides of the fixed plate in the center, one end are fixed in two side on. Four box-type vibration exciter were arranged in sieve plates in the bottom of the three stand on two coaxial, two-axis parallel to the axis line, the two axes by the same parameters of induction motor drive, both by the traditional shaker sieve boxes on both sides of two facets to the source of the vibration power transmission vibration. With the vibrating screen size, and performance requirements under the shaker must be the same width and length of the extension of the sieve shaker widened screen box beams must be extended accordingly, vibration intensity is expressed as K = 2 / g, while the vibrating screen, the screen surface widened 1 times each, will increase the strain beam 16 times, so the beam cross section must be increased rapidly. Now the width of conventional vibrating screen is generally less than 3.8m, to increase the width of the beam cross section Shaker great for the technical difficulties, the overwhelming smell Company Institute and Northeastern University to study Bangchun Fellow, creatively presented "Three extra-wide body vibration transmission elevation by strong vibration equipment," Theory and Technology.
Secondly, WLZR-40 × 85 heavy-duty line outside the screen with Oil Lubrication and cooling equipment. Three wide facade Shaker Vibration Transmission source selection dilute oil lubrication, light oil on the bearing raceway oil flow speed up the oil in a timely manner, continuous film roller full. Grease lubrication performance than the conventional good, high-temperature thin oil cooling process filtered out sediment, the rolling friction and waste products filtered out of metal powder, so that lubricating oil kept clean. Extend the service life of bearing and exciter to reduce the failure rate. Thin oil lubrication outside the cooling device, with the vibrating screen starts automatically oil, temperature, excessive or insufficient fuel supply stop vibrating screen instructions, and number of significant temperature and alarm, the device and network remote control also.
Third, the shaker with the second damping device, start over in the screening phase machine, due to motor starting time is very short, speed increased quickly, excitation frequency in a very short period of time each system rapidly across the shaker The natural frequency, the resonance is not serious. In order to improve the life of sieve and the upper stainless steel punch and the lower stainless steel comb, to improve the wear resistance of sieve. Also reduced the quality of part of the vibration screen machine, screening machine reduces the theoretical design strength. Under the vibrating screen machine, not only to facilitate the operation of the use and maintenance workers, while improving the security screening machine use, can reduce the building area and cost savings. Under the three tier facade
vibrancy WLZR-40 × 85 heavy-duty line screen appeared, filled the blank of this technology, is currently the use of equipment vibration technology used in metallurgy industry, another major technological breakthrough, while Vibration Equipment Co., Ltd. Henan is the mighty R & D, innovation a new milestone.
