Crusher & Delumper


In Bulks Solids & Powder processing industry raw materials are usually big lump sizes which are difficult to process as it is. To reduce it to powder or granular particle size in the range of around 10mm, 15mm or even lesser, an equipment is a must. Our Crusher and Delumper range have been developed to address needs like this. Crusher is an equipment which crushes the big size lumps into small or desired size by using various screen sizes. They are perfectly designed to serve as pre crushers for pulverizers or as an independent crusher or other milling equipment as well.

RIECO Crushers are of double roll type. The crusher consists of an outer housing in which two shafts are installed firmly supported by heavy bearings at either end. Two opposite rows of stars and prongs are mounted on sleeves keyed to gear driven shafts, which revolves towards each other. It Is the principal action between the tips of these prongs that reduce the lumps to a smaller size. Crushers are generally used for the medium soft lumps with less than 1% moisture for use of certain materials. Breaker bars may be installed under the rolls for further reduction.

All units are normally equipped with adequate HP motors and suitable size gear box. The drive consists of chain & Sprocket. Mounted below the crusher jaws on each unit is a large perforated screen designed to prevent oversized material lump from passing out of the crusher. Various screen sizes are used to maintain desired output.

Any crusher can be furnished with a manual re-ser friction clutch mounted on the drive shaft adjustable to wide range of torque capacities. This drive automatically disengages the roller shaft.

DELUMPER is an equipment used to break solids and soft lumps down to desired size by crushing to produce a fine output. They reduce plant downtime, increase processing speed, and improve product consistency. These machine functions at low RPM and is aligned for smooth operation with low vibration or noise.

Our powerful units are designed to handle capacities from 50 Kg per hour to 1000 Kg per hour. Delumpers can be customized to meet special requirements of customers’ applications facilitating easy maintenance with custom sizes.



DELUMPER can handle max 2% moisture, sticky, dry, hard or soft substances. They tear through chemicals, lumps, agglomerates, ore, filter cake, ash, sugar, food, plastics and more. The units are available in various sizes. Particle size can be controlled with change in RPM and different type of perforated screen.
