This process is critical in wastewater treatment, mining, chemical processing, food production, and oil &#038; gas industries. By spinning a slurry at high RPMs, the machine forces water through a filter or screen while retaining the solid cake. The result is a significantly reduced moisture content in the solid waste, lowering disposal costs and enabling resource recovery. Modern centrifugal dewatering machines range from small batch units for laboratories to large continuous decanter centrifuges handling hundreds of tons per hour.<\/p>\n<h2 id=\"toc-721d5d1711b4bb336bb422c7fec0432f\">Global Top 10 Centrifugal Dewatering Machine Suppliers and Factories<\/h2>\n<p>Based on market share, revenue, technology leadership, and global distribution networks, the following are the top 10 centrifugal dewatering machine suppliers worldwide (2025\u20132026 data).<\/p>\n<table border=\"1\" cellpadding=\"8\" cellspacing=\"0\" style=\"border-collapse:collapse; width:100%;\">\n<thead>\n<tr>\n<th>Classifica\u00e7\u00e3o<\/th>\n<th>Nome da empresa<\/th>\n<th>Pa\u00eds<\/th>\n<th>Principais produtos<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td>1<\/td>\n<td>Alfa Laval<\/td>\n<td>Sweden<\/td>\n<td>Decanter centrifuges, solid-bowl centrifuges<\/td>\n<\/tr>\n<tr>\n<td>2<\/td>\n<td>Andritz AG<\/td>\n<td>\u00c1ustria<\/td>\n<td>Separation centrifuges, decanters, filter presses<\/td>\n<\/tr>\n<tr>\n<td>3<\/td>\n<td>GEA Group<\/td>\n<td>Alemanha<\/td>\n<td>Decanter centrifuges, disc stack centrifuges<\/td>\n<\/tr>\n<tr>\n<td>4<\/td>\n<td>Flottweg SE<\/td>\n<td>Alemanha<\/td>\n<td>Decanter centrifuges, belt presses, separators<\/td>\n<\/tr>\n<tr>\n<td>5<\/td>\n<td>Centrisys\/CNP<\/td>\n<td>EUA<\/td>\n<td>Decanter centrifuges, sludge thickening systems<\/td>\n<\/tr>\n<tr>\n<td>6<\/td>\n<td>Pieralisi Group<\/td>\n<td>It\u00e1lia<\/td>\n<td>Decanter centrifuges, olive oil extraction<\/td>\n<\/tr>\n<tr>\n<td>7<\/td>\n<td>Hiller GmbH<\/td>\n<td>Alemanha<\/td>\n<td>Decanter centrifuges, two-phase and three-phase<\/td>\n<\/tr>\n<tr>\n<td>8<\/td>\n<td>Tomoe Engineering<\/td>\n<td>Jap\u00e3o<\/td>\n<td>Centrifugal dehydrators, sludge treatment<\/td>\n<\/tr>\n<tr>\n<td>9<\/td>\n<td>Westfalia Separator (GEA)<\/td>\n<td>Alemanha<\/td>\n<td>Disc stack centrifuges, decanters<\/td>\n<\/tr>\n<tr>\n<td>10<\/td>\n<td>Mitsubishi Kakoki Kaisha<\/td>\n<td>Jap\u00e3o<\/td>\n<td>Centrifugal separators, decanters<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<h2 id=\"toc-ddc3c753eeab6c2d3d293161d783c880\">Top 10 Centrifugal Dewatering Machine Suppliers and Factories in China<\/h2>\n<p>China has become a global manufacturing hub for centrifugal dewatering equipment.

Use a decanter with tungsten carbide tiles and high torque gearbox.<\/li>\n<li><strong>What is the delivery time for Chinese centrifugal dewatering machines?<\/strong> Standard models: 30\u201345 days; customized machines: 60\u201390 days. Express delivery available for urgent orders.<\/li>\n<li><strong>Are Chinese centrifugal dewatering machines reliable?<\/strong> Yes, top-tier Chinese factories use SKF\/FAG bearings, Siemens motors, and stainless steel bowls. Warranty periods of 2 years are common.<\/li>\n<li><strong>How to install a centrifugal dewatering machine?<\/strong> Requires a concrete foundation, electrical connection, and piping. Chinese suppliers provide installation manuals and remote support; on-site service available.<\/li>\n<li><strong>What spare parts are needed for a centrifuge?<\/strong> Common spare parts: scroll tips, bearings, seals, V-belts, and control boards. Keep a 1-year stock for critical components.<\/li>\n<li><strong>Can I test my slurry before buying a centrifuge?<\/strong> Most Chinese manufacturers offer free lab testing. Send 5\u201310 liters of slurry for a performance report including cake dryness and polymer dosage.<\/li>\n<\/ol>\n<h2 id=\"toc-772a13817391960bb5d7ccb17ef8db08\">Customs Data and Tariff Rates (2026)<\/h2>\n<p>For centrifugal dewatering machines (HS Code 8421.19 \u2013 centrifuges), typical tariff rates vary by country: USA: 2.5% (general) \/ 0% (WTO); EU: 0% (duty-free for most industrial centrifuges); India: 7.5% basic customs duty + 18% GST; Brazil: 14% import duty + 18% ICMS; China: 8% import duty (for foreign machines). Free trade agreements may reduce rates. For example, under RCEP, imports from Japan to China enjoy 6% duty. Buyers should check with local customs brokers for exact rates based on machine specifications and country of origin.<\/p>\n<h2 id=\"toc-89f23552f26d61928b063b9b0cd65bbc\">Why Choose Small and Medium-Sized Factories?<\/h2>\n<p>Small and medium-sized factories (SMEs) in China offer several advantages: (1) Lower minimum order quantities (MOQ) \u2013 often 1 unit vs. 5\u201310 for large factories; (2) Greater design flexibility \u2013 SMEs are more willing to modify standard designs for niche applications; (3) Faster decision-making \u2013 owner-managers can approve customizations in days rather than weeks; (4) Competitive pricing \u2013 overheads are lower, translating to 10\u201320% savings; (5) Direct communication \u2013 you deal directly with engineers and owners, not sales representatives. However, ensure they have valid export licenses and quality certifications.<\/p>\n<h2 id=\"toc-57bba6fca35004c6a5d3fcb2a1972d25\">Compila\u00e7\u00e3o de not\u00edcias de abril de 2026 dos principais meios de comunica\u00e7\u00e3o social<\/h2>\n<ul>\n<li><strong>April 3, 2026 \u2013 Reuters:<\/strong> &#8220;Chinese centrifuge manufacturer Hubei Ruichang secures $50 million contract to supply 120 decanter centrifuges for Saudi Arabia&#8217;s new wastewater treatment plants.&#8221;
