Background technique
Currently, traditional sandstone aggregate production line generallys use grizzly feeder and carries out simply in sandstone aggregate production
After desliming, material is uniformly fed to coarse crushing crusher and is crushed, the broken routine of coarse crushing is crushed using coarse crushing Hubei Province, coarse crushing
The broken discharge in Hubei Province enters that circular cone is broken or counterattack is broken carry out in it is broken, discharge enters after screening system sieved, and minus mesh enters list
Constant speed vertical shaft is broken to carry out broken shaping, and discharge enters screen house and sieved, and it is broken broken that oversize material again returns to constant speed vertical shaft,
Qualified products enter finished bin by finished belt machine, oversize material by return conveyer machine be transmitted back in broken circular cone it is broken or counterattack is broken
Broken, the advantages of this conventional crushing production line is that system is simple, saves equipment investment, but configures single, and product quality can not
Guarantee, energy consumption is high, and there are many defects: (1) coarse crushing being carried out to material using Hubei Province is broken, smashing principle based on attrition crushing,
There are the latent defects such as crackle for broken product, and product elongated particles are high, and particle shape is poor, and reduction ratio is small, allow to feed partial size
It is small, to small powder can not attrition crushing and directly pass through, influence the efficiency and finished product sandstone quality of subsequent sand processed；(2) single host is (normal
Fast vertical shaft is broken) technique can only single-stage crushing, it is small that constant speed vertical shaft breaks reduction ratio, produces that sand contribution rate is low, and treating capacity is low, mentions if necessary
High yield, it is necessary to reduce feed size and just be able to achieve, single stage crushing must just be increased by reducing feed size, equally also be will increase and set
Standby investment；Simultaneously: single vertical shaft is broken finished product ratio is adjusted, and also finished product gradation can not be adjusted.If forced
It adjusts, treating capacity can be lower, can not play the broken best crushing efficiency of vertical shaft.
