TAKRAF’s dedicated range of mineral sizers are specifically tailored to suit a variety of applications around the world. Our sizers incorporate pre-engineered modules with application specific features that result in a cost-effective and economical solution boasting high availability, high maintainability and high value.
The TAKRAF sizer portfolio
We have applied our extensive experience in the mining and minerals industries in the configuration of each of our sizers in order to ensure that our machines exceed their real-life application requirements in terms of capacity, installed power, and product size.
The TAKRAF sizer portfolio covers primary and secondary (as well as tertiary) sizing applications. Our Standard Class Sizers offer a highly optimized and economical solution while our X-TREME Class Sizers offer maximum reliability in the most extreme conditions.

Key features of our sizer machines
Some of the key features of our machines include:
- Modular wear components are easy to handle and change-out procedures can be conducted in position
- Heavy-duty bearing design ensures the longest lifetime in the toughest of applications
- Split housing design enables the easy replacement of complete roll assemblies
- Bolted tooth system enable worn teeth to be replaced in seconds
- Quick release crushing segments enable the targeted and efficient replacement of individual plates
- Integrated moving unit enables the entire unit to slide into its maintenance position for safe and quick maintenance-procedures
Optimized maintenance for increased availability
All TAKRAF sizers are engineered with maintenance in mind. Each component is designed to be quickly and efficiently replaced. The reduced downtime for maintenance means that the machine gets back to production as soon as possible.
When minutes count, make the most of every second!
TAKRAF Minerals Laboratory
The testwork that we perform in the laboratory is the first step towards getting the right TAKRAF sizer installed in your application. In the lab, our team of experts run a full spectrum of tests to establish the strength, abrasiveness, crushability and friability of your material. We then analyze and use this data, together with our significant experience and know-how, in order to select the ideal sizer configuration for your specific requirements boasting optimized drive power, tooth configuration and abrasion protection.

Customer Project Name Crushing plant Vostochny Eurasian Natural Resources Corporation Open-pit mine Vostochny, Ekibastuz 2013
Sizer in open-pit mine Vostochny
Based on the experiences of TAKRAF in coal crushers and crushing plants the first hard rock sizers for overburden of up to 200 MPa was successfully installed at the Vostochny mine to crush lumps of up to 2,500 mm down to a conveyable size.
Overburden, mainly sandstone and siltstone 4,250 t/h (max. 6,000 t/h) indirect by apron feeder

Bradford BreakersBradford Breakers are primarily employed to simultaneously size and clean raw coal, although they can also be used to separate other materials.
GranulatorsGranulators are employed in the coal industry where they size run-of-mine coal and remove tramp iron/debris at the same time.
High Pressure Grinding Rolls (HPGR)HPGRs are modern and efficient comminution machines, which are becoming increasingly popular within the minerals processing space.
Roll CrushersRoll crushers are customized solutions for new or existing crushing plants.
Roller Supported ScrubbersTAKRAF designs comminution systems for coal mining and preparation, industrial minerals, mining and processing and other non-metallic mining and processing systems.
