1. To make sure the operation of the shale shaker and normal usage life on screen, the operator need to make sure parts like wedges, screw cap bolt and springs on the shale shaker are installed correctly with no signs of wrongdoing. The operator installs the screens according the operation manual provide it from the seller.
2. To get full usage of the pre-tension shale shaker screen, operator need to ensure the rubber parts of the shale shaker is fully intact and show no sign of damage. Shale shaker screen is wear and tear parts and it will be needed for replacement after normal usage. If wear-down speed is faster than normal, then check all the moving parts of shale shaker is functioning properly and secure the screens correctly.

3. Lubrication and consist maintenance the shale shaker moving parts base on the operation manual is the must to ensure proper operation.
4. If the operator uses an OEM shale shaker screen that have not been pre-tension treatment, it is the must step that need to perform before usage.
5. If the drilling fluid flow out of the pore or damaged place, then cuttings can’t be removed. Any screen with holes or be damaged must be changed immediately, the hole and the damaged place can be sealed up by the panel. The screen must be changed as soon as possible, make a plan before the replacement to reduce the stopping drilling time, you should prepare the tools and screen before beginning to replace, if because the shale shaker is not operating, it will increase the cuttings content. It’s best to exchange the screen in a single period if possible. Need to stop the pump at the emergent time, stop drilling so as to replace the screen of shale shaker.
6. Any problem please fell free to contact us and learn to know our other products including mud agitator, decanter centrifuge, desander, mud tank ,drilling waste managent, drilling mud system etc.

GN mud agitators are high efficiency mud-mixing units offered in a wide array of custom sizes and configurations to accommodate virtually any mud tank. They are mainly used for agitating drilling fluids, avoid particle in fluids deposit to tank bottom.
Today we would like to share our experience on how to design mud agitator. As we all known, the mud agitator stirs mud slurry to maintain suspension of solids. The agitator is mounted on top of the mud tank and has one or two impeller(s) immersed in the mud slurry.
The agitator’s impeller shaft is coupled to an electric drive motor with coupling. The horsepower of the drive motors rates from 7.5HP to 20HP, which is named 5.5kw to 15kw.

Mud Agitator
Single impeller is usually matched for motors below 11kw. And double impellers are more suitable for those above 11kw. Based on user’s request and onsite condition, the vertical location of the impeller on the shaft is determined as a height from the tank bottom corresponding to the impeller diameter times 0.75. Take a 20 inch impeller as an example; it should be mounted at the height of 15 inch higher than the bottom.
GN recommends straight impellers blades for tanks under 5 inch deep and canted blades for deeper tanks. If dual impellers are desired, straight blades are mounted on the bottom and the canted blade impeller is installed at the height of two-thirds above the tank bottom.
By using a multi-piece coupling, the main motor and driven impeller shafts are rigidly connected. The connected coupling is using a tapered bushing to secure the shafts together.
For different customers, the lengths of the shafts are customized to suit customers’ specifications. A special device named stabilizer are usually welded at the bottom of the tank to keep the balance of the entire shaft.

It owns four factories: old factory in city of Tangshan, new factory close to Beijing, a separate factory for shaker screensas well as the above pointed out 1, a new factory with workplace developing and workshop.
GN’s core product mud agitatorwill probably be moved there and production capability is going to be doubled soon. In addition to decanter centrifuges, GN Solids America will establish a separate workshop for centrifugal pumps.
Lately, orders for centrifuges come from everywhere in the planet. Some old customers even complain that GN in no way has in-stock centrifuges. GN is sorry about that also. For each and every lot of beneath production centrifuges(http://www.gnsolidsamerica.com/decanter-centrifuge.html), prior to production finished, all are sold out. The new factory will resolve this problem for GN Solids Control; this can be absolutely good news for both GN employees and GN valuable buyers.

Our customer will apply the agitators on the cylindrical tanks with depth near 4 meters. The agitator is consist of 15KW electrical motor, gear box and shaft with double impellers. The 3.3 meters long shaft is devided into 2 sections, in order to easy transportation and different purpose in operating. The double layer 950mm diameter impeller is designed as movable as per the customer’s requirements, the joint point of the shaft is between the 2 layers impeller, after removeing the down half section, the agitator still could work.

During the communication with our customer, we suggest to install the stabilizer for the agitator to prevent the shaking when the shaft rotating. Considering there is pipeling opening at the bottom of the tank, our customer design the stabilizer impending with the supports connecting with the tank wall, and they will produce by theirself.

Now the agitator is waiting for delivery, if you have requests for our mud agitator and other solids control equipments, just feel free to contact with us.

Paddle Mixer Structure and Operation Principle

Paddle Mixer Include: explosion–proof motor, reducer, seating and impeller. The motor and reducer are installed horizontally on the top surface of the mud tank.
Connection: Rigid shaft adapters are used to connect the motor to reducer, and reducer to impeller.
Operation Principle: The impeller agitates the drilling mud and makes it revolving to enhance the stirring effect. The plate mounted to the impeller shaft by flange with bolts could prevent solid particles in mud from depositing around the impeller so as to reduce the friction force when the shaft rotating.
