Heavy Media Cyclones / Dense Media Cyclones
Featuring exceptional wear resistance, comprehensive model options, substantial capacity, and dependable adherence to wear-resistant materials, our designs are tailored to various coal qualities, thereby ensuring precise cyclone separation
Vibrating Screens - Banana Screens
John Finlay's sturdy vibrating screens are purpose-built for demanding coal washery tasks, delivering high G-values and outstanding screening efficiency. Their design-production synergy is unmatched. With adjustable deck angles, they cater to precise service needs, featuring steep angles of 28-34° for raw coal separation screens and -5-50° for horizontal de-slime/de-reject screens, optimizing output without compromising screening efficiency.
Vertical & Horizontal Basket Centrifuges
John Finlay excels in centrifuge technology, offering Middling & Clean Coal Centrifuges and Slime Centrifuges with global design excellence and top-quality components. These machines ensure durability, high capacity, efficient dewatering, quiet operation, and adaptability to diverse coal qualities. Equipped with an Intelligent Early Warning Health Examination System, they optimize production, reduce costs, and guarantee reliability
Three Product Cyclones
Non-pressure Three-product DM cyclones prevent over-crushing, offer high capacity, efficient rejects discharge, and precise separation with durable corundum lining. Pressure feed Three-product DM cyclones provide high separation precision and adaptability for challenging coals, featuring wear-resistant lining. Our main product, Pressure Feed Two-product DM cyclones (1.1m to 1.5m diameter), ensure precise separation of clean coal, middling, and rejects.
Dense Medium Bath
Customizable models designed for client needs, featuring high alumina tiles and wear-resistant steel lining for durability. Chain rail designed for reduced wear, SEW reducer for reliability, and a casting alloy chain guide. Equipped with hydraulic chain tensioning and automatic lubrication. Interface for Intelligent Early Warning Health Examination System for online monitoring of key components
Magnetic Separators
New magnetic separators with imported components. High-coercivity magnetic blocks and optimized configuration create a powerful magnetic field for +99.9% recovery efficiency in dense medium coal preparation. The drum, made of 304SS, is non-magnetic and wear-resistant. It includes a liquid level adjustment device and a rinsing hole. The interface for the Intelligent Early Warning Health Examination System is reserved for effective machine monitoring and timely maintenance notifications.
Intelligent Early Warning Sensors
John Finlay's Intelligent Early Warning Health Examination System for coal preparation plant equipment monitors key components, issues pre-warnings, and comes with a reserved interface. It ensures smooth operation and proactive maintenance by collecting stable and accurate data, analyzing machine health, and enabling timely action by equipment managers.
Exciters
Exciters, crucial for vibrating screen performance, are equipped with imported SKF or FAG bearings in our FE series, ensuring extended service life, low noise, temperature control, and adjustable exciting force. Our FEA series exciters, an upgraded version, offer maintenance-free operation by eliminating regular grease addition, preventing foreign object entry with breather removal, and addressing oil leakage concerns by removing cased seals, requiring only occasional grease replacement.
Filter Press
The filter press is a versatile tool used in various industries for solid-liquid separation. The device works by applying pressure to a filter cake. Which is formed by the solid particles in the liquid, to separate the liquid from the solid. Additionally, the filtration process of a filter press can be divided into three stages: pre-treatment, filtration, and post-treatment. The filter press has several advantages over other filtration methods.
Flotation Cell / Forth Flotation
John Finlay's XJM-S flotation machine is a self-priming air mechanical stirring flotation machine, which does not need additional air. During the impeller stirring process, it can effectively produce small bubbles, and the inflation rate is 1.0 cubic meter / square meter / minute, and the inflation uniformity is more than 90%. Power consumption per unit volume less than or equal to 2.5kw / m3
