In oil and gas drilling, industrial wastewater treatment, and environmental projects, centrifuges are key equipment for solid-liquid separation, and their performance directly affects production efficiency and compliance with environmental standards. Drawing on over thirty years of experience, Xi’an KOSUN Machinery Co., Ltd. has developed a horizontal screw sedimentation centrifuge. Thanks to its innovative design, high stability, and intelligent control system, it has become a benchmark product in the global solid control and particle separation industry.

Thanks to high-precision dynamic balancing, KOSUN centrifuges can operate stably at speeds of 0–3900 rpm, generating centrifugal accelerations up to 3000G and efficiently separating solid particles ≥2 µm — a critical feature for operations in environmentally sensitive areas. The extended rotor bowl increases material residence time, providing higher dewatering efficiency and improved separation accuracy, effectively addressing the incomplete separation issues typical of conventional devices.

The rotor bowl is made from corrosion- and wear-resistant materials. At the sand-discharge end of the conical section, quickly replaceable carbide tips are installed, and the screw feed surface is coated with a wear-resistant carbide layer, significantly extending service life under harsh conditions. Major components are equipped with FAG (Germany) or SKF (Sweden) bearings, and electrical components meet explosion-proof standards, ensuring high operational reliability.

Its wide range of applications demonstrates its versatility. In the oil industry, the centrifuge serves as the fourth stage in solid control systems, optimizing drilling fluid density and viscosity while significantly reducing preparation costs. In the mining industry, the “screening + centrifuge dewatering and dry stacking” system based on this centrifuge enables water recirculation from tailings and environmentally safe dry disposal of solid residues, supporting both ecological and industrial safety.

Moreover, the equipment is effectively used in chemical, food, pharmaceutical, and other industries, delivering separation performance and productivity that surpass competing solutions.

Energy efficiency and environmental compatibility make KOSUN centrifuges especially in demand under modern industrial conditions. High-quality separation ensures maximum resource recovery: in the oil industry, it significantly reduces waste volume, while in mining it allows the complete return of the liquid phase to the production cycle. Low energy consumption and the capability for continuous operation reduce operational costs and eliminate losses associated with cyclical processes, providing both economic benefits and ecological advantages.

Today, KOSUN horizontal screw sedimentation centrifuges are supplied to over 70 countries and regions worldwide, earning international recognition for their stable performance and high-quality service. From drilling platforms to environmental treatment facilities, from chemical plants to food production lines, KOSUN centrifuges — built on technological innovation and reliability — continue to deliver effective separation solutions. Amid the global shift toward “green” industry, KOSUN will continue to advance centrifugal technologies, contributing to the modernization of industries and improving their overall efficiency.
