Sigma Sand Bag Weighing Filling Machine :- The material handled is Silica Sand, River Sand, Granule sand and Construction Sand the scheme suggested for flow promotion & filling of bags is described below. Material is received from the plant in to a storage hopper of adequate capacity.

Below this hopper is the triple feed sector gate..

The bag filling system is proposed is a net weighment facility wherein the material to be filled into the bag is first weighed out into the weigh hopper and then discharged through

Pneumatically operated valve into the receiving spout (also called clamping head) which is Used to clamp the bag. The bag gets manually clamped by the worker. The weight of the empty weigh Hopper is automatically zero off from the system. The sector gates open & filling starts - allowing materials to flow into the weigh hopper. On achieving the 90 % of target weight the coarse feed gate is closed & then material is fine fed until the target weight is achieved. The filling operation is stopped by closing the fine feed gate above the weigh hopper.

Next the weigh hopper opens & discharges the pre-weighed material into the bag. On achieving the empty condition of the weigh hopper the bottom discharge valve of the weigh hopper closes and the process of filling the weigh hopper starts immediately. The material thus weighed is kept ready to be discharged to the bag spout once the operator is ready to receive the material.
