The sieve bend is suitable for the dewatering,de-sliming and sizing of coal slurry.It has a totally new structural design and incorporates a number of patented technologies,capable of performing vibration-impact-tipping combined functions. Under the effect of vibration and impact actions,the mesh clogging nuisance and the problem relating to the inconsistency of oversize materials can be thoroughly eliminated.As a result,the performance of the sieve is significantly improved.The sieve has been granted 3 national patents.Now,7 sizes ranging from VBOSB 182060 to VBOSB362060 are available
