The screening work is the coal processing important link, it widely uses in screening the factory and the coal dressing plant.
The screening work uses the equipment many shaker is one kind suits the moist thin grade for shaker the difficult to sieve the material dry screening the vibration screening mechanical device, is the present domestic processing difficult to sieve the material the vibration screening mechanical device. The shaker has the great oscillation amplitude, the big intensity of vibration, to compare the low frequency and the elastic screening surface craft characteristic. In the work process maintains the biggest percentage open area throughout, thus the screening efficiency is high, handling ability is big, the lamina crib Rosa replacement was convenient, reduced the cost. The shaker ultra big screening surface and big handling ability may satisfy the scene the production need. The shaker screen's structure uses the multistage screening surface vibration to sieve the box and the rack does not participate in the vibration the mode of motion, caused the screen to realize the large scale.
Our country's straight line shaker research has been backward and is overseas, specially in large scale aspect.
The this design structure and sieves ordinary is dissimilar, it has 4 side bars, the middle both sides are main, the vibrator installs above it, by it to the screening surface transmission vibration power, outside two is secondary, only plays keeps off the yard lumber the role. The material is through three channel screening and the transportation, this kind of structure's biggest merit is the crossbeam size may reduce greatly, reduces the Parameter to inspire the quality greatly. The economic efficiency is very obvious, moreover sieves is bigger, effect more obvious.
The exciting force transmits on directly each part from the side bar, omits the I-girder, reduced has sieved the box weight and the cost, but to sieved the box structural design to propose the high request, we to sieved the box intensity, the rigidity, the center of gravity, the spatial structure to carry on the optimization design for this reason.
