With over 100 years’ experience in vibrating technology, as well as having a significant global equipment footprint, JOEST is a preferred choice for reliability and efficient long-lasting solutions within the mining and engineering sectors.
The screening solutions offered by JOEST are custom built to give an optimum solution for any bulk solids, which require processing. Within the basic industry range, the products screened include hard rock, coal, industrial sands and various types of ore. These are screened utilising both wet and dry processes. For the more difficult-to-screen products, JOEST can customise the equipment for the customers ad-hoc needs.
JOEST is also renowned for developing effective recycling screens for whatever needs to be recycled.
Flip-Flow Screens OSCILLA Family
Screening difficult, inhomogeneous products, requires special processing technologies.
With regular operational blockages experienced utilising traditional screens, the JOEST screens negate this challenge, and the material is dispersed to enable fine grain separation to take place. Conventional screens are usually unable to deliver this performance – this is where the JOEST Flip-Flow Screens from the OSCILLA Family are utilised to maximum effect. Typical screens will operate within a range between 0.5 and 40 mm.
Finger Cascade Screen TopSpin
For pre-separation in recycling plants, cascade screens are increasingly used for difficult-to-screen products. Their advantage is that they can screen, and clear out long pieces of inhomogeneous products with almost no blockages experienced.
Circular Motion Screen
Circular motion screens are used for the pre- or final classification of free flowing, medium- to coarse-grained bulk materials. The basic motion of this screen is a circular motion. Typically designed with an inclination of 10° to 30°, this screen enables the optimum throughput for just about any application.
Linear Motion Screen
Linear motion screens are used to effectively separate most products within an industrial environment.
Finger Rod Screens STABROFLEX and STABROFIX
The STABROFLEX is used to screen bulk materials which tend to clog and cannot be screened on the conventional screen decks. The STABROFIX range can be used for coarse product pre-separation and is renowned for relieving the load on downstream crushers.
GRIZZLY Screens
Heavy duty screens with GRIZZLY bars are mainly used for pre-separation or to relieve downstream crushers from fine materials.
Rod Screen GRECCO
Depending on the geological factors, in the quarrying of natural stone products (e.g. limestone, greywacke, porphyry, diabase, etc.) the material extracted can often contain a more or less high content of soil and clay which blind conventional screen decks. Such material can be screened nearly maintenance-free using JOEST GRECCO screens. This GRECCO screen is basically a STABROFLEX type of execution with self-cleaning effect built in.
Banana Screen
Banana screens are high-capacity vibrating screens. They were developed according to the “thin-layer theory” They are known for improving screen efficiencies by separating most of the fines directly at the feed end.
Dewatering Screen
Linear-motion screens are primarily used for dewatering sand and are popular in most industries.
Wet-Sizing Screen
Wet-sizing screens are used to increase the direct throughput rate and to deliver sharper screen cuts. Furthermore, they can be utilised as washing screens.
JOEST screening solutions are now supported directly from their Johannesburg facility, with a renowned dealer, also offering support in the northern cape region.
JOEST also provides effective aftermarket support such as the reconditioning of exciters, motors, retrofitting as well as refurbishment of machines, parts sales and technical support.
