Hapman introduces a flexible screw conveyor that allows for batching of material within +/- 1 lb. or less of set point. The Loss-In-Weight (LIW) Helix® is a fully automated dosing system that is equipped with programmable logic and system integration tie-in 
functionality, and load cells built into the frame assembly. The flexible screw conveyor carries the material to an elevated point at the required flow rate. Once the load cells indicate the flow volume is within 5 lbs. of set maximum the conveyor is automatically slowed to dribble mode. When the required batch volume is reached, the conveyor is precisely and automatically stopped. The LIW Helix is available from 3” to 8” nominal case diameter with average capacity ranges from .5 to 15 cu ft. per minute and a discharge height of 10 to 12 ft. (depending on conveyor size). Hopper sizes can range from 10 cu ft. up to 60 cu ft. Additional features can be added to the unit such as: a Hi-Lo option for easy raise and lower of the conveyor for cleaning or auger change out, 304 or 316 hopper material, flexible connections, automated and manual discharge shut-off valves, and more.
