KOSUN provides mud recycling and solid-liquid separation systems for Horizontal Directional Drilling (HDD) projects. During HDD construction, drilling mud carries cuttings out of the borehole, lubricates the drilling tools, stabilizes the borehole, cools the drill bit, and helps control formation pressure. As the drilling process continues, the mud collects more solid particles. An effective recycling […]
Tailings Treatment & Dewatering KOSUN provides tailings treatment and dewatering solutions for mineral processing operations, supporting the separation, dewatering, and dry stacking of tailings. The treatment process combines classification, concentration, centrifugal dewatering, and filtration to reduce tailings water content and support the recovery and reuse of process water. Tailings Dry Stacking Tailings are generated during

TBM Muck Treatment for Shield Tunneling TBM muck treatment is designed to handle the excavated material generated during EPB shield tunneling. The muck mainly consists of excavated soil, slurry, additives, and groundwater. KOSUN provides a TBM muck treatment system for separating sand, fine sand, and soil from excavated muck, followed by dewatering and volume reduction.

Drilling operations generate large volumes of drilling fluid containing drill cuttings, sand and other unwanted solids. Without effective solids control, the continuous accumulation of solids can affect drilling fluid properties, increase equipment wear and reduce the efficiency of the circulation system. KOSUN provides drilling fluid solids control solutions designed to separate unwanted solids, maintain drilling
Drilling Fluid Solids Control System Read More »
A drilling fluid system is often discussed in terms of solids control: shale shakers remove drilled cuttings, hydrocyclones separate finer solids, and centrifuges provide further separation. But separation is only part of the process. The drilling fluid still needs to move continuously between tanks, separation equipment and other treatment stages. When the fluid contains a
Why Is Slurry Pumping Important in a Drilling Fluid System? Read More »
Modern cities are running out of above-ground space. Engineers now build metro lines, utility tunnels, and stormwater corridors underground. Contractors use shield tunneling and Tunnel Boring Machines (TBMs) as the standard approach. These machines bore through dense urban ground with minimal disruption to street-level traffic. However, every meter of advance creates a massive byproduct: tunnel

A mud tank may look simple, but its performance depends on much more than its steel structure. In drilling operations, it needs to withstand demanding working conditions, support fluid circulation, and integrate with other solids control equipment. This is why mud tank manufacturing matters. Field performance starts at the factory. Mud Tank Fabrication: From Steel
