Malvern - Demagnetising Coils for Magnetic Slurry Processing
Demagnetising coils are specialized tools engineered to mitigate the residual magnetism in magnetite and ferro-magnetic materials as they navigate through vertical pipelines, particularly after processing in wet drum magnetic separators. These coils are available in various internal diameters, ranging from 4 to 10 inches, with other sizes offered upon request. Construction involves varnished copper wire wound around a bobbin, protected by epoxy resin against moisture and physical damage, and shielded by laser-cut stainless steel guards. The electrical-grade, non-metallic material used for the bobbin supports operational temperatures between 80° and 95° C, with built-in thermistors set to trigger at 105° C, providing a safe cutoff point. Installation requires the coils to be mounted in a manner that ensures the slurry-carrying pipeline passes directly through the coil center, ideally using non-metallic pipeline materials. Proper setup and maintenance are essential to ensure operational longevity and safety.
Malvern - Dry Magnetic Roll Separators
Malvern Engineering Works provides high and low intensity dry magnetic roll separators which are essential for the mineral, pharmaceutical, and chemical industries. These separators leverage over 75 years of engineering expertise, advanced magnetic modeling software, and in-house laboratory facilities that enable the company to offer adaptable and cost-efficient machines tailored to meet specific client requirements. Key technical features include the design of a rare earth roll magnetic separator with a rotating drum composed of powerful neodymium-iron-boron magnetic material. This design ensures an optimal combination of magnetic field strength and gradient, maximizing the separation effectiveness. The equipment also features a variety of magnetic roll types, material feed systems, and robust drive and control systems. These separators are strategically designed to align with contemporary industrial needs, ensuring reliable and efficient operation in diverse application environments.
Malvern - Model HMD - Heavy Media Drum for Dense Media Separation
The Heavy Media Drum (HMD) is engineered for dense media separation of materials ranging from 10mm to 300mm. Its cylindrical drum features conical sections and is equipped with a feed chute, sinks launder, and perforated lifters for effective separation. The drum is mounted on two forged steel tires and rotates via a drive system comprising V-belts and a motor connected through a gearbox. The assembly is supported by steel roller configurations to ensure stability, with thrust rollers controlling lateral movement. The drum's internal setup is designed for separation efficiency, as denser particles are transported to the sinks launder while lighter ones overflow for media recovery. All components, including flexible and rigid skirts and pipework, are supported by horizontal beams, allowing for precise control of media density within the drum for continuous operation. This machine finds extensive application in industries where precise separation of dense materials is essential.
