GN Solids Control makes various sizes of screw conveyor augers for the oil gas industry. The screw conveyor augers are widely used for transfer the drilling cuttings to feed to the cuttings dryer,and cuttings collection box.GN designed 3 size of diameter, 10inch, 12inch, 14inch, 18inch, each size has 4 different length for option according to the drilling site of the customer.GN Solids Control can offer fixed speed gearbox drive and manual adjustable speed gearbox for each size of gearbox.
Some clients want to use Standard Bearing with seal (if possible double bearings) instead of Middle Hanging Bearing core in the hanger bearing for the connection of each auger sections. GN Solids Control does not recommend this design.
Firstly, standard bearing and seal design are costly. Plus it is more complicated to install.
Secondly, the bearing at this location is easy to be worn out,especially be worn out by drilling mud and drilling cuttings. If the seal is not good enough at this location, the bearing will soon be broken.
Moreover, it is inconvenient to replace the bearing and seal after wear. The operators need to fully dismantle the auger for replacing new ones. As far as we know, there are no suppliers in China use standard bearing at this position. Their popular design is using copper sleeves at this location.
GN Solids Control use hanger bearing which are made of alloy materials to fit for oil field drilling waste transfer. Alloy material is more wear-resistant than copper. Plus, GN Solids Control makes the hanger bearing in the form of a separate unit. The parts can be quickly replaced by removing the bolts and mounting brackets in case of needed.
GN Solids Control use helical gear reducer (speed adjuster). It is more stable and less maintenance.
Besides, clients will want there are clear separation between the electric motor and manual speed adjuster (gearbox or reducer) to enable job site operators to remove the electric motors for repair without affecting the gearbox (speed adjuster or reducer). GN Solids Control connect the driven motor and gearbox (speed adjuster reducer) by flange. It is easy for installation and dismantle.
