Lyn Bates answer is very right. I joint him in this matter.
The discribed case is a clasic and well known problem of descharging divice and silo outlet dimansions. Both should be in relation to the material properteis and process requirements.
We in Dafna Eng. are handling such cases at our regular activities. Vibration is definatly no the solution. It will make things worther and un stable.
We would like to aske for a basic drawing of your instalation, in spite to submit you a detailed answer and basic instraction for your aplication.
Best regards

This sounds as though the extracting device is not progressive along the whole length of the outle slot of the hopper. If a screw feeder is fitted the geometry of the screw flights are not properly proportioned. Vibration in such a case will only make matters worse. Email a sketch of all details available and of the product stored, and I will examine the prospects for retrofitt. ■

Paul,
We are the largest manufacturer of UHMW. Our trade name is TIVAR. We have a lot of experience in the area of bulk solids flow. However, you question is not decriptive enough for me to make any comments on your problem. Please contact me directly and I will have one of our engineers give you some advice.

I am going fabricate and line the inside of
several large hoppers that I will fabricate in
the next 6 months out of S.S. materials.
Last year this co.moved aprox.1,450,000 met.
tons of products in this facility. Some being
corrosive, with others being abrasive in nature.
Any,and all help would be a greatly appreciated!
Thank You ,

I have a 60m3 hoppper lined with UHMWPE which experiences
mass flow over 3/4 of its length, from back towards the front.
We are finding some hangup near the front. Can anyone advise whether
vibration at the end of a load cycle would be an option?
Or simply compound the problem? ■
