Price Guide: POA

The versatility of conveying vertically and horizontally enables the conveying tube to be run in a route that avoids many obstacles in a production facility. Long radius bends reduce wear and pressure loss within a system although Tee bends are sometimes used on fragile or very abrasive products.

The two most common forms of pneumatic conveying are Vacuum Conveying and Pressure Conveying. The selections of which type of conveying system is to be used and on whether the system is Lean Phase or Dense Phase, is determined by various factors such as product, distance, cost, conveying rate etc.

Vacuum conveying is often a low cost method of pneumatic conveying where product can be conveyed up to 60m at rates up to 15tph. It is ideally suited to the loading of extruder hoppers or direct loading of blenders or other such vessels.

The receiving vessel is put under vacuum and the product metered into the conveying line at a rate suitable to the conveying velocity and at the desired air to product ratio.

Filters fitted to the receiving vessel or a stand-alone filter separate the product from the conveying air prior to the air passing through the vacuum source.
