Vortex mixer mixes solid additive with drilling liquid evenly. It is

suitable to the basic equipment in configuration of equipments for

drilling liquid. This mixer adopts rotational flow mixing technology,

and can fill betonies and barite, etc into drilling liquid quickly in

order to be adapted to complicated drilling process. This product

is of good mixing effect, quick filling of material, and no-blockage.

Jet mixer works generally together with shearing pump and is

mainly used to mix chemical medicine which is not easily

dispersed in drilling liquid. Due to high pressure at the outlet, it

can be installed under level of mud circulation tank.

Mud gun is the special tool to prevent the mud precipitation in the drilling circulation system. The impetus of mud gun can come from either centrifugal pump or

mud pump. With simple structure, flexible operation, easy using, to make use of high speed drilling fluid flow to prevent precipation.

Mud gun generally mounts on the drilling mud tank roof; it is divided into high pressure and low pressure mud gun. High pressure mud gun with small discharge

capacity, larger pressure, work with drilling pump to supply liquid; low pressure mud gun with larger capacity and lower pressure usually work with centrifugal

sand pump to supply liquid.
