Linemann-solving customer problems
     
Clinging
The build up of materials around the sides of the storage vessel reduces its useful capacity and requires more frequent filling. Old material, breaking free, will contaminate current production.
Linemann air blasters will trim the sides of the container and then prevent the build-up.		   Ratholing
This is a more serious form of clinging and reduces the capacity of the vessel to such a degree that only the central channel is available. Previously only manual clearing, air or water hosing was available with consequent contamination of the product or damage to the vessel. Linemann Air Blasters will cure this and prevent its recurrence.		  

Arching
High arching is a very difficult problem to cure manually and case histories reveal that, with operators prodding from underneath, potentially the most dangerous one. Blasters sited high on the vessel side will collapse the arch and restore flow quickly and efficiently with no danger to personnel.

  

Bridging
This is a common problem especially with fine materials. Bridging across the outlet results in complete loss of production and costly down time.
Hammering the area around the outlet is a consuming exercise and eventually results in damage to the structure. Correct siting and firing of Linemann Air Blasters will restore flow.
             
With air blasters

From concept through to commissioning, we will install and maintain a system of Air Blasters - which discharge compressed air at high velocity into the material within the storage vessel, displacing it and restoring the normal free flow pattern.

The Air Blasters are placed in situ, and fired in a pattern, according to the location of flow problem, the design of the vessel, and the characteristics of the material stored.

Whatever the material - coal fines, cement, sand, ore, salt, chocolate, wheat, sugar, etc. - we assess each problem individually on site and propose a cost effective solution. From a single push-button system to one with multi-programmable logic control, we guarantee the equipment's performance throughout its life.
