Multotec manufactures, supplies, installs, commissions and services a complete range of coarse and fine coal centrifuges. We supply the largest range of centrifuges, ranging from 800, 1 000, 1 200, 1 300, 1 400, 1 500 and 1 650 mm basket diameters. Each size can have a basket cage angle between 10-30° depending on application.
Our technology has the largest tolerance for feed variation, making them both operator-friendly and reliable. We can achieve export or local quality lowest moisture contents through our vibrating coarse coal centrifuges and screen scroll fine coal centrifuges.
Moistures as low as 6% can be achieved with our dewatering centrifuges, where up to 300 g centrifugal force is applied. We also supply fine coal decanters for ultra-fine coal dewatering or drying.
The Conturbex screen scroll centrifuge is used by the world’s largest mining houses in fine coal processing. This coal centrifuge features a scrolled / wormed design developed by Siebtechnik over 60 years of application experience. Using a slight speed differential between the screen and the drum, uniform acceleration of solids can be ensured and sliding speed and retention times can be controlled.
Use the Conturbex fine coal centrifuges after processing through hydrocyclones, spiral concentrators and dewatering screens.
Designed for long-lasting performance in the toughest coal dewatering applications, the Siebtechnik vibrating coal dewatering centrifuges are equipped with polyurethane doors, steel feed pipes lines with ceramic tiles and a durable wedge wire screen fitted within a robust cage design.
Coal washeries use Multotec vibrating screen centrifuges for medium and coarse coals after processing through hydrocyclones, sievebends and static screens, and waste drain and rinsing screens.
Multotec has a highly trained team of experienced engineers, with extensive process and application knowledge providing unmatched advice and support for our coal mining centrifuge range. We offer this aftersales expertise through an established, strategically located service and distribution network to guarantee high levels of service delivery, including full maintenance contracts on equipment.
We also serve other industries with our broad range of centrifuges available to chemical, food, pharmaceutical, industrial, water treatment and zero liquid discharge processes.
