Alumina
Alumina, a refined product derived from bauxite, is as fine as powder and as fluid as water. Its lightweight, free-flowing nature demands an airtight grab design. Nemag’s MVG grab with sealed shells and durable rubber liners prevents wind loss and ensures maximum containment. The rigid shell construction maintains shape integrity, ensuring a long service life — a standard that has made Nemag the global benchmark for alumina handling.
Animal feed
Free-flowing materials such as corn, soybean meal, or animal feed demand smooth handling and clean surfaces. Nemag grabs equipped with food-grade lubrication and precision sealing ensure gentle yet efficient transfer while maintaining hygiene standards.
Barite
Barite is a high-density mineral used as a weighting agent in oil drilling and as a pigment in paints. It’s heavy, compact, and difficult to penetrate. Nemag’s scissor grabs deliver the necessary closing force and control for efficient loading under high-pressure environments, such as offshore applications.
Cement
Bulk materials like cement clinker, sand, and crushed stone are key ingredients in the construction industry. Their varying density and abrasiveness require grabs that are both strong and easy to maintain. Nemag grabs combine power and precision, enabling high-capacity handling without compromising on safety or durability.
Clinker
Clinker is a dense, abrasive material with irregular particle sizes, typically handled in high volumes and harsh operating conditions. These characteristics require robust equipment with high wear resistance and reliable control. For clinker handling, Nemag offers NemaX grabs, clamshell grabs, and scissors grabs, designed to manage heavy loads efficiently while reducing wear and maintaining stable performance.
Cokes
Cokes, produced from metallurgical coal, serve as a carbon source in blast furnaces. Depending on grain size, they can be handled with either a NemaX or an MVG grab. Nemag customizes grab configurations to the specific size and density of the coke, ensuring optimal performance and efficiency.
Concentrates
Concentrates are extremely valuable and notoriously sticky. Their fine particles tend to adhere to grab surfaces, leading to loss and contamination. Nemag’s NemaX grab is available with stainless steel shells, minimizing adhesion and ensuring the material discharges completely and safely — protecting both your cargo and your bottom line.
Fertilizers
Fertilizers can vary widely in form, from fine powders to coarse granules, and may be sensitive to breakage, moisture, or contamination. Accurate control and clean handling are essential to preserve product quality. Nemag's clamshell grab is well suited for fertilizer handling, providing controlled filling and discharge while minimizing product degradation and material loss.
Limestone
Limestone is a heavy bulk material that ranges from fine fractions to large, abrasive particles. Its weight and variability demand a combination of strength, durability, and efficient filling. Nemag supplies NemaX grabs, clamshell grabs, and scissors grabs for limestone applications, ensuring reliable handling, reduced spillage, and long service life.
Minerals
Minerals vary widely in form, from coarse rock to fine powders. Each type requires a specific grab design to achieve optimal fill and prevent material loss. Nemag offers high-performance grabs that ensure efficient loading and unloading while reducing spillage and wear.
Petcoke
Petroleum coke, or petcoke, is a by-product of oil refining. Depending on its form — green or calcined — it may require different handling solutions. For green petcokes, Nemag provides perforated grabs that allow water drainage during underwater unloading. For finer, dry petcokes, Nemag’s sealed MVG grab ensures clean, environmentally safe transfer.
Pig iron
Pig iron, a semi-finished product of raw iron from blast furnaces, varies in form and size — from pyramid-shaped ingots to long bars. Nemag’s orange-peel grabs provide the gripping power and durability needed to handle these dense, irregular materials with precision and control.
Salt
Salt is a challenging material due to its corrosive nature and tendency to harden during long sea voyages. When unloading salt, operators need robust grabs capable of breaking crusted material while resisting corrosion. Nemag’s MVG grabs deliver both — powerful enough to penetrate hardened salt and durable enough to withstand long-term exposure.
Scrap Metal
Heavy Metal Scrap (HMS) and shredded scrap demand a completely different approach. These materials vary from large steel parts to smaller cut pieces, each requiring different claw configurations. Nemag’s orange-peel grabs are designed for maximum strength, adaptability, and safety. They can be equipped with radioactivity detection (RA detection) on request — an essential feature in some regions.
Soy
Soybeans are relatively lightweight but sensitive to mechanical stress, as crushing can reduce product value and increase dust. Gentle handling with precise control is therefore essential. Nemag's clamshell grabs are designed to handle soy carefully, supporting smooth operation and consistent throughput while maintaining product integrity.
White bulk
White bulk materials, such as salt, sugar, or similar products, are often free-flowing but require clean handling to avoid contamination and product loss. Smooth surfaces and controlled discharge are key to maintaining quality. Nemag's clamshell grabs provide reliable, hygienic handling for white bulk materials, supporting efficient and clean bulk transfer operations.
Wood pellets and chips
Biomass materials such as wood pellets and wood chips are increasingly used for renewable energy production. Pellets are uniform and easy to handle with a sealed MVG grab, while wood chips — often moist and compacted — may require additional digging force or a polyp grab when heavily packed. Nemag provides both options, ensuring reliable unloading under any condition.
