Resin Dosing System Has:
- DAY TANK
- WEIGH HOPPER
- WEIGH HOPPER MOUNTIG STRUCTURES
- LOAD CELL ARRANGEMENT
- CONTROL VALVE
- PUMP ASSEMBLY
- BRAIDED HOSE ARRANGEMENTS
- 7’’ HMI
Over View:
The day tank has capacity of 1000 Liters, Resin from 250 litres barrel is transferred to day tank by the resin transfer pump. Similarly, the resin from day tank to weigh hopper is transferred through gear pump. Weigh Hopper has capacity of 140 litres and has mounting bolts and nuts along with 3-point load cell arrangement. The resin is transferred in the SS pipe line and discharged into the weigh hoppers through the automated coarse and fine valve which controls the quantity of discharge into the weigh hopper. Resin from weigh hopper is discharged into the Mixer through automated shut off valve and required quantity of Resin from the day tank is fed into the mixer through the weigh hopper based on the selected recipe. Pipes from the day tank to the weigh hopper will be supported by clamps and structure. PLC panel with HMI is provided for actuating the entire operation and we have provided manual valve for maintenance purposes. The left-over resins in the pipeline are fed back to the day tank through return line. Day tank should be drained out completely before plan for continuous shutdown.
Customer Benefits: We gave the high accuracy, hygienic and time minimizing solution to our client.
