GN CBM Drilling Mud System

Equipment description
GNCD930 vertical cuttings dryer is used for drilling waste management, to remove the particles below 3mm;The dryer can reduce the liquid content in cuttings ( WBM / OBM / SBM), to make the discharged cuttings comply with the requirement of environment protection; recover the valuable drilling mud and lower down the drilling cost.
During drilling, theoretically speaking, about 1-4 barrels drilling fluids can be recycled from each barrel of drilling cuttings removed by solids control equipment. Theoretically speaking, GN drilling cuttings dryer system consisting of Vertical cuttings Dryer could recycle about 1 barrel drilling fluids from 3 barrels drilling cuttings
structural compositions and working principle
The dryer is composed of frame assembly, filter unit, driving system, lubricating system, Inlet/outlet device etc
Filter unit
This is composed of screen basket, bell jar combination, rotor assembly etc. The screen basket gap can be chosen per jobsite requirement
Driving system
The power is from ex-proof motor. The motor drive the main pulley, the main pulley drive the gearbox housing via V belt, the gearbox drive the bell jar combination and screen basket assembly. Fix the gearbox input shaft, to make the gearbox output shaft speed little lower than gearbox housing speed, to drive the rotor assembly in a speed which is slower than screen basket assembly rotation speed
Lubricating system
This power unit body applies centralized lubrication system. The lubricating oil in the oil tank is pumped into power unit via the oil pump, from top to down flow back to oil tank via oil return pipe which connected with oil pan
inlet/outlet device
The device including material feeding hopper, liquid outlet, solids discharge etc
The feeding hopper is on top of upper shell, the material go into filter unit via feeding hopper, spread on screen basket inside wall evenly via distribution plate.The liquid outlet is connected with lower shell liquid outlet channel, to discharge the liquid from dryer.Solids discharge port is

GNCD series vertical drilling cuttings dryer
GN can GNCD series drilling cuttings dryer is the domestic first can handle oil-base mud and water base mud vertical dryer, as domestic famous brand can produced solids control equipment, it has advanced design, good processing effect, long service life, etc, has been all over the world is widely used in waste pulp treatment. In the process of drilling, theory usually solids control equipment each isolated 1 cubic meters of solid drilling cuttings, can recycle about 1 to 4 cubic meters of drilling fluid. Designed. the GN cuttings dryer and matching equipment, drilling cuttings drying system can in theory from three cubic meters of drilling cuttings recovered about 1 cubic meter of drilling fluid (specific data according to the scene material state of feed, the feed speed, the way of conveying the material and so on).Drilling cuttings dryer can also and centrifuge, become a whole set of drilling waste management system, used to dry drilling cuttings, recovery of drilling fluid.

The main effect of drilling cuttings dryer
Reduce water-based, oil-based mud drilling cuttings or composite base mud drilling cuttings total emissions, thereby reducing waste pulp to be processed, to meet the environmental emission requirements.
Recycling valuable drilling fluid, so as to reduce the drilling cost.
Reduce the liquid content in the cuttings, in order to improve the follow-up waste pulp processing equipment processing power.
Finally, designed the GN dryer can help users to achieve environmental protection, reduce the quantity of waste liquor, maximize the drilling fluid recycling, reducing drilling cost.
Crown vertical drilling cuttings dryer product advantage
High separation factor – work of up to 900 RPM, can form the separation factor of 420 g, effective separation of drilling cuttings in the fluid.
Treatment effect is good, the drilling cuttings liquid content is usually less than 5%, can satisfy the requirement of the typical 6% OOC.
Ability to process large – capacity are usually 30 to 50 tons per hour (processing capacity and mud viscosity also have very big concern, and the slurry viscosity and solid content, grain size, types of drilling fluid and drilling fluid temperature and other factors)
Long service life, discharging scraper composed of high chromium cast iron casting, long service life.
Variable frequency optional – can provide constant speed drilling cuttings dryer not only version, more frequency version for you to choose, speed can be adjusted from 0 to 900 RPM freedom, more flexible.

As is known to all, conventional solids control equipment, such as vibrating screen, desander, desilter and centrifuge can separate 2-5 micron particles, the tiny particles, it is difficult to by a simple mechanical separation method. But with the ongoing of drilling, ultrafine particles accumulate if, in the mud circulating system, drilling have a big impact in the long run. Drilling contractors have to drilling fluid to reach the purpose of drilling using is being continuously diluted.This creates more waste of water resources, and produce more drilling waste.GN SOLIDS CONTROL can GN1500 series 20 feet box type flocculent dosing system into a 20 foot container after decorating the room, easy operation and transportation. Through this system can dewatering centrifuge with champions league, and elevating bracket and for slurry pump, can meet the requirements of customers overall solutions.
Sludge flocculation centrifugal dewatering system works
Crown can GN1500 series 20 feet box type flocculent dosing system is mainly chemical flocculant automatic configuration, used for auxiliary dehydration centrifuge separation of water-base drilling mud tiny particles, so as to get clean water for industrial use. By using GN1500 series 20 feet box type flocculent dosing system with crown to high-speed frequency conversion centrifuges, can separate ultrafine particles in water base drilling mud, to meet the requirements of the recycled water.
For mud does not be born the circulatory system, flocculation and dewatering system is particularly important, it can help keep clean mud drilling company, and can reduce the drilling waste. To reduce the overall operating costs. For the heavy mud, first through mechanical centrifuge separation, recovery of heavy metal and stone, and then into the dosing flocculation centrifuge separation system.
Sludge flocculent dosing dehydration system main components
1) PAM automatic soluble medicine device (PP box, three groove continuous stirring)
2) mechanical diaphragm metering PAM dosing pump
3) flocculant soluble drug dosing device
4) coagulant aid mechanical diaphragm metering dosing pump
5) 20 feet container tall ark

Lubrication
Lubrication of bearings
Lubrication position and time intervals see Table 5.1. The lubrication for main bearing should be done during normal operation of centrifuge, fill lubricate until it overflows from lubricate discharge. The reasonable amount of lubricate is to 1/3 of lubricate tank, in case of lacking lubricate, the bearing might be burnt, while in case of over lubricate might cause abnormal heating up.
Lubricating holes of impeller big and small end bearings are respectively on the big and small end covers, and the lubricating work should be done during the centrifuge is stopped. Open the upper cover of collection box and screw off the jack screw, and respectively inject 25g and 86g lubricate into small end and big end with grease gun. When injecting lubricate, symmetry jack screws should be screwed off in order to allowing existing lubricate to discharge.
Lubrication of gear box

After 300 hours of first time running of a new gearbox, lubricate must be changed. Before filling in the new lubricate, the inner chamber of differential mechanism must be clearly drained. Re-lubricate with new lubricant after every 1000-1500 hours operation per above mentioned instructions. Use mesh 100 filter when lubricating. Obstacles like iron scraps adsorbed on the magnetic plug must be cleaned every time when lubricating or re-lubricating. Check the lubricate amount per figure 5.2. Adjust the lubricate hole to 30 degrees to horizontal, when the lubricant is just to overflow, it means lubricating is enough. (Not to fill it totally full).
Lubrication or Feeding Pumps (see operation manual of centrifuge feeding pump)
Before delivered from factory, bearings are already well lubricated, and also differential mechanism and couplings, and passed the 4 hour unload commissioning test. When you start to use of decanter centrifuge or re-start it after a time, please check all the lubricating points and check if there is oil leaking on differential mechanism and couplings. Re-lubricate per conditions.
