Mud mixers are mainly used in horizontal directional drilling industry. It is designed to provide complete suspension of the mud and cuttings. This provides a uniform feed to the mud cleaning equipment regardless of the mud weight. This results in sending less sand and silt back into the mud pumps and into the hole, reducing wear and increasing the life span of pump liners, drill string, bearings and other moving parts. The features of these mixers include tank multi jet motion, vacuum induced waist high hopper, stainless steel filter, and cast jetting tee.
