GN designed GNCD930 vertical cutting dryer is already finished and tested in the field. Its specs is similar with CSI cutting dryer WSM-04. Its rotary speed is 890rpm, and processing rate is 30~50tons per hour( actual data). Max bowl diameter is 930mm.

Daily inspections should be made at start-up until a permanent maintenance schedule can be set up. Once a schedule has been established, only routine inspections and general observations will be necessary.

Cutting Dryer Maintenance

1 Basket:

Basket is not wear part, unless its damage caused unbalance, you do not have to replace it before that.

2 Filter-screen:

it is important to always maintain flite to screen clearance,it is critical to the proper machine performance.

3 It is very important to inspect the condition of the rotor at every screen change. This is necessary as the rotor is the connecting member between the external drive shaft and the basket, and is one of the members which is subjected to normal abrasive wear by the product.


Except for the motor bearings, which are grease lubricated, all bearings are oil lubricated. A direct driven gear pump, mounted along the outer base, circulates oil through the gear unit and overflows to the outer external shaft bearings.

The oil should be changed every 1600 hours of operation or every three months, whichever occurs first. To change oil, drain oil from the gear unit and drain pot.

What is slurry pump?

A Slurry pump is a type of centrifugal pump in physics principle that increases the pressure of liquid and solid particle mixture, through centrifugal force (a rotating impeller) and converts electrical energy into slurry potential and kinetic energy.

There are 2 kinds of slurry pump, horizontal type and vertical type, for vertical type pump, there are submersible slurry pump and underwater pump. Submersible slurry pump is widely used for drilling fluids transferring, underwater pump is used for fluids transfer. Horizontal slurry pump is also used for drilling slurry transfer, just the installation method is different to meet different mud tank size.

What is vertical slurry pump?

Vertical slurry Pump is the cantilever pump structure of single stage and single suction, with the bearing housing, supporting, intermediate pipe connecting the pump hydraulic components, the water is discharged out from the drain pipe parts, pump impeller is for semi-shrouded with the agitating vane on the vane extended, the main characteristic of this pump is the underwater pump shaft parts have enough rigidity, the impeller and pump shell have no bearings, no shaft seal, which can transport the greater medium of solid particles. The length of inserting the water by pump is between 800 and 2000, the suction pipe can be matched in case of need. Continue reading »
