Multotec manufactures spares for every single part of its DMS and hydrocyclone ranges, amounting to over 10 000 producible cyclone spares.
Using specialised cyclone sizing software to achieve optimum centrifugal forces and cut points to precise requirements, Multotec’s process team selects and sizes the ideal cyclone for your application requirements.
As world-renowned cyclone manufacturers, Multotec’s engineers have the expertise to custom design and manufacture cyclones to your exact specifications. Multotec customers are able to make use of the Multotec Online Sizing application software, which allows them to size their own cyclone. Multotec double-checks all self-sizing requests to ensure the most appropriate cyclone for your industrial processes.
Through extensive testing and simulations, Multotec’s scrolled evolute design is proven to have has a higher capacity when compared to other inlet configurations.
This scrolled evolute design significantly reduces vortex finder wear. The result is high efficiency cyclones as the particles now follow the natural spiral trajectory. The scroll section also facilitates natural particle separation before they enter the classification zone.
Weep holes are used to drain the material that falls between the cyclone liner and cyclone shell. Weepage usually indicates that the liner is damaged. Weep hole use extends the life of hydrocyclones’ steel shells and reduces unplanned cyclone stoppages. They also reduce the frequency of internal hydrocyclone inspections, as cyclones without weep holes will require regular liner inspections
Multotec’s condition monitoring products for cyclones include:
These innovative condition monitoring products help increase your cyclone’s service life. These solutions are also used across various industries to monitor their cyclone wear solutions. Some benefits of monitoring the condition of your cyclone wear liners include:
Multotec has developed software to size cyclones correctly. CY-i Cyclone Sizing Software provides Multotec customers with a scientific, structured approach to selecting dense medium cyclones or classification cyclones.
Customers achieve appropriate cyclone selection by using input variables within their plant configuration to determine their ideal cyclone configuration. The software facilitates:

Cyclones effectively and selectively concentrate slurry particles in a process that separates and classifies them. It is a simple process that separates slurry mixtures so that larger particles leave through the hydrocyclone’s underflow. The remaining water and fine particles exit through the overflow.
The precision in the classification process extracts even the finest precious minerals, preventing waste and the natural force generated by the shape of the cyclone reduces energy consumption. Waste prevention and low energy costs contribute to better returns.
Cyclones are integral products to process minerals effectively. Their cylindrical top and conical base create a vortex, in turn creating a centrifugal force. It is this centrifugal force that separates and classifies the various size particles by forcing lighter particles through the top overflow and larger solid particles exit via the bottom underflow.
Removing particles from an air, gas or liquid streams through vortex separation without any filters is the function of industrial cyclone separators.
Initially called a cyclonic separator, it was patented in 1885 by the American John Finch. Designed for use as a dust collector”, the technology found wider industrial appeal by offering large scale separation in factories or mills during the 1900s.
An industrial cyclone has no moving parts and is made up of a vertical cylinder with a conical bottom. The cylinder is closed at the top with only enough space for the vortex finder (liquid overflow pipe) extends into the cyclone body.
