             Currently, the process of glass raw materials—- aposandstone (sand stone, silica) and feldspar generally adopts the  following process:
                 
                  A. Wet-process rod milling.  
   B. The multistage crushing and screening line is composed of impact crusher, cone crusher or jaw crusher together with mutual roller. But these two processes have the following disadvantages:

            Manufactured Sand Processing Chart:  
 1. Material Bin  
 2. Vertical Shaft  Impact Crushers  
 3. Inclined  Vibrating Screen 
 4. Sand  Washer or Powder Separator 
The characteristics of the new process line: 
 1. The equipment  investment is less and it can save more than 50% of investment comparing with  the above two process “A&B”.  
 2. The metal  consumption is low.  
The main machine of the new process:    
?、?Primary crushing  jaw crusher adopts GFP series heavy load jaw crusher. The operation life of the  jaw plate is over 6 times of PE series jaw crusher.  
 ② Sand making machine is currently the preferred  equipment of crushing high ablation material internationally, which adopts the  principle of using stone to strike stone. Its outstanding feature is the high crushing  efficiency and low metal consumption. 
?、?The new  process adopts dry process. 
?、?The fine powder content of the new process line product  conforms to the process requirement of float glass production. The new process  line can be used in the crushing of sand rock, Aposandstone, silica and  feldspar and has obtained ideal effect in the re-crushing of broken glass.  
Typical process line:  
   1. Shandong Glass Group (feldspar) has three production lines. 
   2. Mongolia Haijing Glass Group (sand rock) has two production lines. 
   3. Qiqiha’er No. 2 Glass Factory (waste glass). 
The flow of the new technical equipment is as follows: 
   ●↓Primary crushing jaw crusher 
   ●↓Fine crushing jaw crusher 
   ●→Sand making machine 
   ●↓Bolting machine 
   ●→Finished product  |
