EQUIPMENT > SYSTEM OF METERING AND PACKING OF SAND (FINES, GRAIN etc.) INTO BAGS WITH SCREENING

METERING HOPPER FOR PACKING OF MATERIAL INTO BAGS



We offer specially developed line for screening and packing of sand (fines, grain) into bags. In case metering and packing set is used for packing of sand, the following mechanisms shall be used:

  • vibration screen - serves for sand screening, sieve 8 mm;
  • auger (screw conveyor) - serves for delivery of screened sand (grain) for packing;
  • weight controller - serves for accurate dosing of materials, with function of line operation statistics' display;
  • other mechanisms

Where:

1- strain gage frame, 2- bag, 3- feeding mechanism (screw conveyor - auger or belt-type conveyor), 4- weight controller, 5 - vibration screen with receiving bin, 6- vibrator.

PACKING LINE OPERATION ALGORITHM


  • Operator selects the required packing dose (for example, 50 kg) on the control panel (controller), "tails" and lags being taken into account
  • Empty bag is mounted and fixed on receiving strain gage platform (for example, woven polypropylene bag with polyethylene insert) of 25 or 50 kg by volume;
  • Workers pour sand (grain etc.) onto vibration screen (receiving bin) using shovels (or feed mechanism);
  • Feed mechanism (auger) and vibration screen are switched on, material is screened and transferred to the bag for packing;
  • Filling of the bag starts - its weight changes, feed mechanism is switched off upon reaching of specified limit;
  • The bag is taken from the frame and delivered to sealing device;
  • The cycle is repeated.
