DPC (Deep Pan Conveyor) OR Clinker Conveyor

DPC is used to convey the clinker from the grate cooler to blending silo.

For clinker transportation shaker troughs or vibrating chutes with high frequency oscillation amplitude were used. However, these troughs or chutes could be used only for horizontal transportation of clinker. For vertical transportation it was necessary to transfer the clinker into bucket elevators or into swing bucket conveyors. 

DPC to Blending silo

These clinker conveying machines developed much dust not only during horizontal transportation, but also during transloading in vertical conveyors. These drawbacks motivated the cement machinery manufacturers to develop new-styled transportation arrangements, so-called bucket apron conveyors, which are able to convey the clinker not only horizontally but also on inclinations (mostly 40-45 c, in exceptional cases even up to 60 °) almost without generation of dust.

When planning a clinker conveying installation, a filling level of 75— 80'% should be considered, When locating the steel cell conveyor directly underneath the clinker cooler, the conveying capacity should correspond to the normal kiln capacity at a 40-- 50 % cell filling level to prevent overfilling in case of possible kiln ring breakage, However, drive capacity should be set as for 100 % cell filling level. Further, it is important that capacity reduction factors are applied when considering inclined conveyors as compared to horizontal conveyors, Spillage is minimized by steep inclines or when the pans articulate over the head or tail shafts. This type of conveyor is ideally suited for handling hot clinker in the cement plants or for conveying materials from fines to 150 mm lump size.

Features

v Good for conveying of clinker with a high content of fines

v Minimum spillage

Benefits

Efficient and reliable operation

Suits applications with limited space

Low operating costs

Minimum and easy maintenance

Outstanding service life

Chute from DPC (Deep Pan Conveyor) to Bucket elevator

DPC convey the clinker into the bucket elevator through the chute. This chute should be designed with care so that there should not chocking problem occur.  It is necessary that one end of the chute covers the whole DPC head end so that no spillage of clinker.  Another end of the chute should cover the bucket elevator inlet. It also take care chute should be with proper angle. Angle of chute should be greater than 45 degree. Chute should be with lining of wear plate so that wearing strength of chute increased. If possible there should be small door in chute in maintenance purpose so that we can see the problem easily if occur.
