Multotec hydrocyclones are used across the world for applications in mineral processing, manufacturing, food processing, waste water treatment and other industries.
This industry-proven product range of classification, dense medium and tailings dam cyclones has been optimised over hundreds of applications across the world to improve classification efficiency, provide greater lifespan and reduce energy requirements.
Multotec manufactures a complete range of off-the-shelf and customised cyclones in order to match your specific process requirements. Full technical support and field service, together with high availability of cyclone spare parts and accessories helps ensure maximum plant performance.
High-capacity classification cyclones are made with a steel shell and lined with rubber or ceramic as required by your application.
The ultimate in alumina tiled cyclone design! Our DM cyclones provide max. separation efficiency and wear resistance in harsh applications.
GV Cyclones are designed specifically for use in tailings dams. These cyclones weigh just 45 kg, with a 220 mm ID and 20° cone angle.
Cost-effective, highly-efficient and long-lasting, our wide range of cyclone distributors accommodates between 2 and 62 cyclones with cyclon...
Get your hydrocyclone spare parts quickly and conveniently at your local Multotec branch. Liners, spigots, valves, adapters and more!
Multotec manufactures spares for every single part of its DMS and Hydro Cyclone ranges, amounting to over 10 000 producible cyclone spares.
The Multotec hydrocyclone range comprises cyclone diameters from 25 to 1 400 mm. Most of these diameters can accommodate a range of cone angles, while different vortex finders and spigot diameters are standard for all diameters.
The small diameter cyclones, up to 165 mm, are predominately polyurethane, while the larger diameter units can be supplied in polyurethane, steel cyclones with bonded or loose rubber lining, and steel with ceramic lining.
Scrolled evolute design:
Multotec has proven that the scrolled evolute and ribbon inlet cyclone designs have a much higher capacity when compared to standard inlet designs. The result is that vortex finder wear is substantially reduced, thereby lowering operating costs while maximising hydrocyclone separation efficiency.
The benefits of weep holes in the cyclone:
If the hydrocyclone liner becomes damaged, the material which finds its way between the liner and the cyclone shell will begin to ‘weep’ from these holes, indicating that the liner needs to be replaced. This drastically reduces unplanned stoppages and will extend the life of the hydrocyclone’s steel shells.
Weep holes also reduce the frequency of internal hydrocyclone inspection. This is because cyclones without weep holes require regular inspection to assess the integrity of the liner itself.
Cyclones are selected and sized by Multotec’s experienced process team using our specialised cyclone sizing software to achieve optimum centrifugal forces and cut points to best suit your precise requirements. Should you prefer, you can also size your own cyclone using our Online Multotec Sizing app and send for review, For specialised applications Multotec can custom design and manufacture a cyclone to meet your application.
Hydrocyclones need to be correctly maintained to ensure they operate at peak separation efficiency. Your local Multotec branch has the necessary expertise to help ensure your cyclone reliably delivers your required cut points and process parameters, with short lead times on any hydrocylone spare parts you may need.
Maintenance should preferably be done on every maintenance shutdown in order to allow for internal inspection. Your local Multotec service crew will provide end-to-end cyclone inspections and servicing, which includes:
With the Multotec pressure gauge installed on your cyclones, plant operators will be quickly notified if there is any surging or pressure drop in the hydrocyclone feed. The reading on the pressure gauge will allow for an accurate calculation of volumetric flow rates to the hydrocyclone which will make it possible to calculate the mass flow rate.
Lower cyclone pressure results in inefficiencies while high pressure increases the centrifugal force beyond its design specifications, which increases cyclone wear rate. Ensuring your cyclone operates in the correct pressure range enables optimum cyclone operation, helps reduce costly potential downtime and improves downstream processing performance.
