Hi All:
We are Polypropylene Web Film manufacturers and I would like to add some pellet blending capabilities.
Traditionally, our company has used gravimetric blenders to perform this function. However the models I’m looking at are intended to feed directly to our extruders. It seems to me, that there may be less labor-intensive designs available, specifically the maneuvering and efficiently emptying of the additive gaylords.
Does anyone have any different recommendations? The weigh scale accuracy (< 1/2%) of the gravimetric system is it’s most attractive feature.
The material:
- All materials are in pellet form at 35 lbs/ccf
- Base pellets, plus up to three additives with similar properties.
- Throughput to be approx 2,000 lbs/hr.
- Annual volume is approx 5,000,000 lbs.
The process would be:
- Base pellets: pneumatic convey from silo to blender
- Additives: Vacuum load from (1,000 lb) cardboard gaylords to blender. Tilters used for the efficient emptying of gaylords.
- Blend & discharge to either tote or discharge hopper
- Dilute pneumatic convey to silo.
Thanks for your time.
