30KW shaft-mounted reducer for hot hoister asphalt plant with anti-reversal device
 
1. Hot aggregate elevator
 
A. Summarization
Hot bucket elevator employs buckets installed on two chains to deliver aggregate that heated by dryer to screen continuously. The chains and buckets run in shell to prevent filler from flying everywhere.
 
B. chain and buckets:
Not only the first-time running, but also after replacing chain or bucket, when it runs four to five days, check and tighten all connection bolts is necessary. It is suggested to sign during checking to ensure no one is missed.
 
C. Chain tension
Use adjusting bolts on tail axle to keep tension. Allow tail axle assembly to move up and down, so as to prevent impacting load. The two-side adjustment should be equal. After first running, pay emphasis on any loose phenomenon in assembly to prevent axle from moving improperly, being damaged or overloaded.
 
D. Chain disassembly
If the chains are too loosened, and bolt adjustment cannot compensate it, then the chain needs to be shortened.
Loose the adjustment bolts to maximum, open tail checking door, attach two chains with a firm wire rope, then draw them closely, disassemble 2-loops of each chain, reconnect the chain, then remove wire rope. If more than 2-loops need to be disassembled, the surplus one should be done at another section, so as to avoid interfering between two buckets.

Reinstall all checking doors and inlets board before running.
Tension chains with adjusting bolts, and tension them again after first-time serving.

 
E. Wearable board
Check the wearable boards installed at inlet and outlet termly, and replace them if necessary. Abrasion of all chutes lies on mix tonnage and aggregate quality.
 
F. Daily maintenance
. Check and screw down all tightening bolt between buckets and chains.
. Check abrasion of chain after a long time using especial decide that the abrasion belongs to single-side or normal one.
. Check the underside adjustment usually for block.
 
G. Lubrication
According to lubrication schedule.
