Solids Control & Drilling Waste Management
GN shale shaker vibrator is Italy Oli brand vibration motor, which is with good quality and stable performance.
Linear motion shale shaker utilized 2pcs same power vibration motor, for example, GNZS703 use 2pcs 1.5KW vibrator. Their installation method is vertical. 
Balanced elliptical motion shale shaker use 2 pcs different power vibration motor(1 large, 1 small), e.g. GNPS703 shale shaker use 1 pc 1.94KW + 1pc 1.0kw. Their installation method is horizontal in parallel.
Mud cleaner is used as the 2nd and 3rd phase separation of drilling fluids, used after shale shaker. After treated by mud cleaner, the clean drilling mud is re-used to the well, the cuttings are collected and enter into drilling waste management system.
Mud cleaner is used before decanter centrifuge, it can separate most of the large solids and less the solids content in the mud, to less the burden of decanter centrifuge so that the service life of centrifuge can last longer.
As centrifuge is the most expensive equipments in solids control system. For this reason, a good mud cleaner is much more important. Some clients do not use under-flow shaker on the mud cleaner, they only use separate desander and desilter, then all the rest works are done by the centrifuge, it will damage very fast. Or some clients only use a small screen area mud cleaner, so some of the large cuttings leaked into the tank to damage the centrifuge screw propeller and feeding pump.
Drilling mud from rig overhead manifold flow to shale shaker, mud cleaner，the cuttings processed by shaker and mud cleaner is transferred by screw conveyor to vertical cutting dryer. 
The solids processed by Vertical cutting dryer is discharged from solids discharge port, get recycled mud in mud recycling tank, which is pumped by centrifuge feeding pump to decanter centrifuge, the separated solids is discharged from centrifuge solids discharge port, the clean mud come back to solids control system.
Mud agitator lubrication including gear box lubrication, bearing lubrication.
Before operation, lubricate gearbox with L-CKE/P 220~320# worn gear oil . Verify that lubricant level in the gearbox reaches the bottom of the oil level plug.
Bearings should be cleaned and re-greased on the same schedule as oil changing. After cleaning, fill bearings to one-third of their free volume.
After 100 hours of initial startup, clean gearbox inside, add new grease oil. Then lubricated at every 2500-hour interval.
A mud balance is a device used to measure the density (weight) of drilling fluid. Mud balance consists of a base and graduated arm with cup, lid, knife-edge, rider, built-in spirit level, and a counterweight. A plastic carrying case is provided to hold the balance intact and in it’s working position.
Density is read at the point where the slider-weight sits on the beam at level. A mud balance can calibrated with water or other liquid of known density by adjusting the counter weight. Most balances are not pressurized, but a pressurized mud balance operates in the same manner.
Solids Control is one of the most important process of drilling. The reason for using mechanical solids control equipment is to remove detrimental drilled solids from the mud system. Effectively removing unwanted solids from the drilling fluid on the first pass through the solids control equipment is an important factor in maintaining drilling fluid properties and reducing drilling fluid cost. 
Mechanical solids control equipment including: shale shaker(separated by wire mesh), mud cleaner, desander, desilter( by accelerated G-force) and decanter centrifuge.
Gas buster can be also called as poor boy degasser, mud gas separator. 
GN standard gas buster is ZYQ1000, with 39.4 inch diameter, 1400GPM treating capacity, dimension is 2000 mm diameter x 5860mm height, weight is 2000kgs. Fluids intet pipe diameter is 4inch, fluids outlet pipe diameter is 8 inch, gas discharge pipe diameter is 8inch, we can made customized pipe dia if the required qty is large.
Gas buster is normally used together flare ignitor, after the dangerous gas is separated out, they use a flare ignition device to burn it.
GN has 6 units Vacu-Flo degassers in stock, welcome to inquiry us.
How to maintain vacuum degasser?
1.The top cap of degassing vacuum cylinder should be cleaned weekly to eliminate gas channel plugged by any wastes.
2. Cut off the power after use.
4. At operation, check the vacuum gauge frequently.
5. Drain off the water after use each time.
6. Main shaft bearing should be added sodium base grease (abut 250~300ml every other month with a lubricant injector).
7. To the vacuum pump working and lubricating condition of the bearing should be checked frequently.

Weighting materials are a high-specific gravity and finely divided solid material used to increase the density of a drilling fluid. How to add weighting materials to the drilling fluids?
In most oil & gas drilling solids control system, there are weighting tank, which has a mud hopper and mixing pump, the operator add the additives from the top of the venturi hopper, the mixing pump transferred the drilling fluids through the cross under the hopper, under the working of pressure, the power material are added to the drilling fluids. It will be mixed by mud agitator installed on the tank. Sometimes shear pump will be used instead of centrifugal pump.
