Posted: September 20, 2010  Views: 17

The B series VSI crusher is the first choice for artificial sand making and stone shaping. Its high performance and low costs make it stand out from traditional sand making machine. B series VSI crusher is specially used to provide excellent aggregate material to highway, railway, building, city construction and hydropower industry.

Zhengzhou Kefid machinery CO,. LTD has launched P series VSI crusher, B series VSI crusher and deep rotor VSI crusher. Only the deep rotor VSI crusher has a replaceable hammer. Worn hammer with combined type is only changed to reduce operating cost 30%. Another pair of vice hammer is added to prevent from damaging main hammer and side plate.

A rotor of a vertical shaft impact crusher has rotor plates distributed along the length of a rotor shaft and secured to the shaft. Aligned, open, recessed cavities in multiple rotor plates receive a backing bar spanning the plates and the bar is secured to the plates. A removable hammer bar seats in the cavities and rests against the backing bar. Wedges held in place by retainers hook the hammer bar in place.

In a rotor for a vertical shaft impact crusher, it is important that any hammers provided be capable of operating over an extended period of time without replacement required. By constructing the hammer and its mounting in such a manner that the hammer may be turned over to provide a new striking edge, the service life of the hammer is appreciable extended. Any mounting for the hammer should hold it securely in place, since it should be obvious that were a hammer to work loses during operating of the crusher, because of the operating speed of the rotor and the weight of the hammer, considerable damage could result. While a hammer should be held securely, nevertheless, the mounting for the hammer should be such as to enable the hammer easily to be removed and turned over or replaced.

Besides the replaceable hammer, the deep rotor VSI crusher also has many comparative advantages. Such as, rotor with deep chamber increases 30% capacity after perfect design; side plate direction can be changed to increase material utility ratio, operating ratio can be increased 48%; Rhombus shape impact plate is used to prevent side plate from being damaged; Spread dish with double purposes can make two feeding ways change easily; Motor with high grade of protection is selected.
