We offer Circular Motion Screens. These Screens are used to segregate various size fractions in coal lignite streams. These are also used to reduce load on crushers by removing fraction which is already smaller than required size or to recirculate oversize fractions from crushed product stream back to crushers. Possible application is in Mines before dispatch to power plants. These Screens are available in 1, 2 and 3 decks to get 2, 3 and 4 size fractions respectively. Each size fraction may be requiring different post processing.

We offer Linear Motion Screens. Linear Motion Screens are used in similar situations as above but where the height is limited by surrounding facilities or screening of small fractions and high throughput is required

We are offering roller screens. As opposed to above two types which are based on bed stratification principle, roller screens are based on free fall principle. These are used in screening run of mine coal lignite when feed stream consists of difficult, sticky, clayey, moist materials and would choke and blind the screen apertures of normal screening machines. It is also good for handling feed material containing larger boulders along with smaller particles

We offer High Particle Acceleration Screens. Also known as Flip Flo Screen, these are ideally suited for screening applications for fine grain size materials (3 mm to 10 mm) with high moisture and screening capacities up to 250 metric TPH. The outer frame is agitated by means of eccentric shaft drive. The vibration is passed on to the inner frame via flexible thrust plates. Screening mats between the inner and outer frame are clamped and flexed by the two vibrating frames. The relative movement of both screening frames creates a “trampoline effect” in the screen mats to create-

We are offering vibrating feeders. These feeders are used to reclaim feed stream from storage bins hoppers or as a feeding equipment to crusher & screen where the materials are not easy to handle (wet, clayey or lot of ash content), having size fractions ranging from big lumps to significantly high percentage of wetmoist fines and where scalping is also needed.

We offer Motorised Trippers. These devices are mounted on conveyor belts running on top of long bunkers with several compartments and are used to discharge the material from the conveyor equitably all along the length of the bunker.

We offer Roll Crushers. Single Roll Crushers are used to crush ROM Coal (1000 mm- 1500 mm size) to (-) 200-300 mm size. In Coal Preparation Plants the coal feed is to be further crushed to (-) 25 mm size by using Toothed Double Roll Crushers. Smooth Double Roll Crushers can be used for crushing up to (-) 5mm.
