View Valve SpecsThe Federative Republic of Brazil is experiencing unprecedented structural demand for industrial-grade anhydrous and hexahydrate magnesium chloride ($MgCl_2$). From the vast iron ore haul corridors of Carajás to the soybean plains of the Cerrado, specialized equipment is vital to achieve regional supply independence.
Brazil's mining belt in Minas Gerais and Pará faces rigorous environmental oversight under ANM and IBAMA mandates. Magnesium chloride hexahydrate solution provides superior hygroscopic dust suppression along unpaved haul roads, drastically outperforming ordinary water spraying by retaining moisture up to 21 days while cutting water truck fleet diesel usage by 70%.
As the world’s leading exporter of soybeans, sugar, and beef, Brazil consumes substantial magnesium nutrients. Agricultural-grade $MgCl_2$ serves as a rapid-absorption foliar micronutrient to prevent magnesium deficiency in acidic Cerrado oxisols and acts as an essential rumen electrolyte in high-yield livestock feed formulations throughout Goiás and Mato Grosso.
Petrobras exploration in the pre-salt Santos Basin demands dense, shale-inhibitive brine systems. High-purity magnesium chloride acts as an osmotic stabilizer preventing wellbore hydration collapse. Concurrently, chemical manufacturers utilize our equipment to isolate high-value magnesium salts from caustic brine effluent, eliminating discharge penalties.
Magnesium chloride is one of the most aggressively corrosive process fluids in the global chemical sector. In tropical Brazilian coastal environments like Mossoró and high-humidity inland mining complexes, improper alloy selection causes catastrophically rapid stress corrosion cracking (SCC) and pinhole pitting.
Traditional stainless steels (such as AISI 304 or 316L) routinely degrade within months when subjected to boiling magnesium brine ($>105^\circ\text{C}$, chloride concentrations exceeding $200,000\,\text{mg/L}$). Weifang Ruitu utilizes an uncompromising metallurgical matrix designed for minimum 15-year service life:
Every vessel undergoes hydrostatic testing, helium leak containment verification, and 100% radiographic weld seam evaluation prior to crating at our Shandong factory.
Crude bittern (28-32° Bé) is treated with barium salts or calcium chloride to remove interfering sulfate ions ($SO_4^{2-}$) and precipitated hydroxides.
Brine is concentrated in titanium falling-film exchangers to 42-45° Bé under controlled vacuum, preventing unwanted thermal hydrolysis into MgO and gaseous HCl.
Hot, concentrated liquor is fed into an internal-spray water-cooled rotary flaker drum, solidifying into uniform, dust-free 46.5% $MgCl_2 \cdot 6H_2O$ flakes.
High-efficiency secondary drying lowers surface hygroscopicity before automated 25kg/1000kg bulk bagging with PE/PP vapor-proof hermetic liners.
Importing industrial process plant machinery into Brazil demands strict adherence to labor, electrical, mechanical, and taxation statutes. Our turnkey delivery models fully bridge Sino-Brazilian industrial engineering expectations.

Brazil represents distinct climatic, chemical, and geographic terrains. Our magnesium chloride processing equipment is customized to match regional feedstock realities and logistical corridors.
Brazil’s solar salt heartland around Mossoró and Macau generates millions of cubic meters of residual "água-mãe" (bittern) annually. Currently, vast volumes are returned to the Atlantic, discarding thousands of tons of dissolved magnesium and potassium.
In the Iron Quadrangle (Quadrilátero Ferrífero), mining conglomerates require heavy-duty dust suppression for hundreds of kilometers of unpaved off-highway haul roads carrying 240-ton ore trucks.
High-yield commercial grain producers require specialized fertilizers. Magnesium is vital for chlorophyll synthesis, yet standard dolomite lime releases too slowly for intensive double-cropping seasons (Safra & Safrinha).
Textile printing, paper mills, wastewater coagulant formulations, and specialty magnesium oxychloride (Sorel) cement construction boards.
Industrial energy in Brazil—whether derived from biomass boilers, natural gas, or the national SIN electrical grid—demands maximum thermodynamic efficiency to guarantee plant operating margins.
Traditional steam evaporation consumes 0.25 to 0.35 tons of steam per ton of evaporated water. Ruitu’s titanium centrifugal turbo-compressor re-compresses secondary boil-off vapor, recycling latent heat back into the primary heat exchanger. This slashes external boiler steam requirements by over 80%, yielding paybacks in under 24 months in Brazilian energy markets.
Every plant comes integrated with advanced PLC automation supporting Profinet and Ethernet/IP protocols. Real-time control loops monitor density (Bé), evaporator pressure, boiling point elevation (BPE), and cooling water flow. Touchscreen HMIs are fully configured in Portuguese with multi-level role-based access.
Integrated vibration transmitters on flaker drums and continuous acoustic monitors on turbo-compressors stream diagnostic metrics to cloud monitoring platforms. Ruitu engineers in China can perform remote diagnostic audits, tuning thermodynamic control parameters in real time alongside Brazilian maintenance teams.

View Auger DesignProcuring industrial magnesium chloride equipment requires careful evaluation of feedstock chemistry, site utilities, and operational goals. The following framework assists engineering managers in preparing technical RFP specifications.
An exact ICP laboratory analysis of your raw brine is the essential first step. Key parameters include: $Mg^{2+}$ concentration, $Na^+$, $K^+$, $Ca^{2+}$, and crucially, the sulfate ($SO_4^{2-}$) ratio. High sulfate concentrations alter boiling curves and foul heat exchangers unless targeted chemical precipitation or gypsum separation stages are integrated.
Define your end market target: 32%-35% concentrated liquid solution (for dust suppression or wellbore brines), 46.5% white hexahydrate flakes (for export, animal feed, or agrochemicals), or anhydrous $MgCl_2$ prills (for titanium metallurgy and metallic magnesium electrolysis). This dictates whether a cooling flaker or multi-stage fluid bed calciner is required.
Map your plant's utility profile: live steam availability (pressure, temperature, cost per metric ton), industrial cooling water (tower circulation vs. open seawater loops), and power grid capacity. If live steam is constrained or costly, our MVR (Mechanical Vapor Recompression) systems are prioritized over traditional multi-effect setups.
Detailed answers addressing engineering specifics, logistical handling, customs optimization, and operational longevity.
Chloride stress corrosion cracking (CSCC) is common in austenitic stainless steels (AISI 304/316L) when exposed to hot chloride solutions above 60°C. Weifang Ruitu resolves this by deploying a targeted metallurgical approach: titanium Grade 2 or Grade 12 (Ti-0.3Mo-0.8Ni) for falling-film and forced-circulation evaporator heat exchanger tubes; pure Nickel 200/201 cladding for high-temperature concentration kettles; and seamless virgin PTFE/PFA linings on carbon steel shells for transfer manifolds, flash tanks, and valves. This construction delivers over 15 years of continuous service life without halogen pitting failures.
Yes. All Ruitu machinery delivered to Brazil can be pre-engineered to satisfy NR-12 (Machinery Safety) and NR-10 (Electrical Safety) regulations. This includes dual-channel Category 4 safety interlocks, physical guards on rotary drums and screw flights, emergency stop pull cords, and fully isolated electrical enclosures rated IP66. We also supply complete documentation dossiers in Brazilian Portuguese (including risk assessments, single-line diagrams, and P&ID drawings) to enable smooth validation and issuance of the ART (Anotação de Responsabilidade Técnica) by registered CREA engineers.
The choice between MVR and MEE depends on site utility economics. Multi-Effect Evaporators (triple or quadruple effect) require a steady supply of low-pressure boiler steam (0.3–0.4 tons of steam per ton of water evaporated), making them well-suited for facilities with access to low-cost biomass boilers (such as sugarcane bagasse or wood waste). Conversely, MVR utilizes an electrically driven centrifugal compressor to recycle secondary boil-off vapor, virtually eliminating boiler steam consumption during normal operation. In regions where steam is costly or gas-fired, MVR typically cuts thermal operating expenses by 60%–80%, providing a rapid payback on investment.
Under the Brazilian Ex-Tarifário regime managed by CAMEX (Câmara de Comércio Exterior), import tariffs (Imposto de Importação) on capital goods (BK) can be reduced from the standard 14% down to 0%, provided there is no equivalent machine manufactured domestically in Brazil. Because advanced titanium MVR evaporators and specialized rotary drum magnesium flakers are not produced domestically in Brazil, our team assists buyers by providing detailed Portuguese technical specifications, process descriptions, and custom tariff classifications (NCM codes) to support successful Ex-Tarifário concession approvals prior to shipment.
Our plants handle diverse magnesium-bearing feedstocks, including: concentrated seawater bittern from solar saltworks (common along the coast of Rio Grande do Norte); inland saline lake brines; byproduct effluent from potassium chloride and bromine extraction; industrial wastewater from titanium sponge production; and acidic magnesium leach solutions from mining hydrometallurgy. Each system begins with a comprehensive raw feed assay review, sizing the pre-treatment, sulfate precipitation, and evaporation steps to match your specific incoming chemistry.
We provide full-lifecycle support. Our engineers can be deployed on-site to any Brazilian state to oversee mechanical alignment, structural anchoring, electrical cabling, pressure testing, and dry/wet commissioning. We conduct hands-on training for local operations and maintenance teams in Brazilian Portuguese, staying on-site until the equipment consistently meets its daily capacity and product purity targets. In addition, all plants feature remote SCADA telemetry gateways, enabling real-time remote diagnostics and support from our engineering headquarters.
