As long as there is a drilling project, there must be a solids control system coming along, no matter it is for land rig drilling or offshore drilling far in the oceans, an efficient solids control system are vital for the drilling fluids recycling and drilling cuttings transportation, especially for the offshores.



In offshore projects, cause of the distance from the land, all material must be used to the most, the most liquid should be reused and least cuttings to be transported back to land. The shaker is used for separating out the most of solids, for handling the heaviest burden, the high performance and strong structure of shaker is quite important. Following features of GNZS series shakers ensures the shaker’s quality and performance:

1. A high G force up to 8.5G powered by Oli Vibrator for a good separation work.

2. Stainless steel shaker deck is stronger for handling the high G force.

3. Patent design of rubber sealing, effectively avoided the leaking of mud.

4. Two different models, with 3 or 4 pieces of shaker screens, providing large treating capacity of 120cbm/hr or 140cbm/hr.

5. Special patented way for changing screens, safe and human oriented.

Talking about shaker screens, as is known to all, shaker screens’ quality greatly affects the shaker’s performance. That’s why GN has built up a separate screen factory for better control over screen quality. In this shaker screen factory, GN is the first and only one who uses robot for welding and cutting, and GN’s screens are in accordance with API RP 13C, an accurate API number and a high conductance with a good screen frame structure made of composite material.

For more information, welcome to contact GN Solids Control directly and welcome to visit GN factory at any time.

API RP 13C is a new physical testing and labelling procedure for shaker screens. To be API RP 13C compliant, a screen must be tested and labelled in accordance with the new recommended practice. The tests describe a screen without predicting its performance and can be performed anywhere in the world. Internationally, API RP 13C will become ISO 13501.

API RP 13 C Screen Cut Point

The API RP 13C shaker screen cut point test is based on a time-proven testing method used by ASTM to classify particles by size. The procedure utilizes a series of standard-size screens (sieves), which have been used for such analysis since 1910. The API standards committee simply adapted the use of these sieves to designating shaker screens. The shaker screen designation is identified by matching the screen’s cut point to the closest ASTM sieve cut point.

Hook Strip Screens

Hook strip screens are also available. Because of the superior life characteristics of the panel mount units, they have been relegated to a minor role on linear motion machines, although they are used extensively on circular and elliptical motion machines. Proper tensioning (and frequent retensioning) of all screen types is good screen management and can significantly increase screen life. Individual manufacturers operation manuals should be consulted to obtain the proper installation methods and torque requirements, where applicable, for specific screens/ panels.

Bonded Screens

Several types of bonded screens are available. The repairable perforated plate screen has one or more layers of fine mesh cloth bonded to a sheet of metal or plastic with punched, patterned holes. Perforated plate designs are available in various opening sizes and patterns. Additional designs include a special application where backing and fine screen(s) materials are bonded together, eliminating the need for perforated plates. Flat-surfaced, pretensioned screen panels are becoming popular because of their even tensioning, easy installation, and the even distribution of liquids and solids across the screen deck.

There are many manufacturers for API RP 13C standard shale shaker screen, GN Solids Control is one manufacturer in China build shale shakers as well as shaker screens with more knowleage of screen and shakers. Please contact us for inquiry freely
