Solution Overview
Minors Accuracy:
The plastic pellets that this company manufacturers contain several minor ingredient additions that are
supplied in atypical forms (blocks, chips, etc.) The Shick solution involved incorporating an indexing
belt conveyor where precise amounts of ingredients can be added.
Homogeneous Batches:
During the course of a given run, the characteristics of the batch change over time. However, the customer
wanted a homogeneous final packaged product. Shick incorporated a 1500 cu. ft. blending silo that stores,
and subsequently mixes, each batch through a conveying loop. These multiple conveying loops create a
homogeneous batch. A Shick Tube Selector Valve in the loop diverts the pellets to packaging after
blending is complete.
Dust Control:
The plastic pellets are conveyed from the blending silo to truck load-out holding bins. The blending
and conveying creates a fine dust intermingled with the plastic pellets. In order to remove the dust
from the product, elutriators were mounted on top of the holding bins, providing particle size.
