A TATA Enterprise

Technical Features Specially designed for high capacity crushing of coal and lignite (range from 40 to 1700 TPH).

Unique crushing action results in higher output and lower power consumption.

Maximum feed size up to 500 mm.

Ideal for product size of (-) 20 mm, with uniform granular product.

Crushing action involves minimum attrition and hence produces minimum fines.

Maximum accessibility is provided to ease the routine inspections.

Ring Granulator

Easy replacement of wear and spare parts.

A TATA Enterprise

TRF's Ring Granulators are rugged, dependable units, specially designed for continuous high capacity crushing of ROM coal and other medium hard friable materials. These are ideal machines for crushing coal to a size suitable for pulverisation, in power stations. The unique crushing action by combining impact and rolling compression in a Ring Granulator results in higher output with lower power consumption. They offer better overall economy in terms of power consumption and maintenance. Ring Granulators are available with operating capacities from 40 to 1700 tonnes per hour and feed size up to 500 mm. Positive adjustment of clearance between the cage and the path of the rings is provided to compensate for wear and to adjust or maintain product gradation. Internal parts such as breaker plate, cage bars or screen plate, crushing rings and liners are made of abrasion and shock resistant steels for optimum working life.

SPECIAL FEATURES

 Positive Adjustability -Quick, easy external adjustment of the cage assembly can be done while the crusher is running

 

Longer Parts Life - screen plate or cage bar wear compensated by simple adjustment to desired clearance  

Automatic Removal of Tramp iron - rear access door allows fast, easy removal of debris

Ring Granulator

 

Hinged Cage - adjustable concentricity with the rotor balances wear evenly among all cage bars  

Wide Hopper Opening - results in uniform, even feeding no bridges and material build-up

Frame Fabricated from heavy steel plates with large inspection front and rear doors, fitted with dust tight seals. Access for further maintenance is provided on the top. Doors on the sides above the rotor shaft facilitate removal of the rotor without completely dismantling the machine. Hydraulic door opening arrangement (optional) can be provided, if required

Frame and Hopper Liners Replaceable abrasion-resistant steel.  

Rotor Assembly Statically/dynamically balanced to operate with minimum of vibration and noise. Weight concentrated within rotor eliminates the external fly-wheels.

 Rotor Shaft Forged and heat treated alloy steel.  

Suspension Bars Duplex suspension bars are provided in all models.  

Crushing Rings Heavy cast Mn-steel toothed and/or plain Crushing Rings depending upon applications.

Cage Frame Fabricated from heavy steel plate and supported from heavy hinged cage shaft at top and provided with adjusting mechanism at the bottom.

Cage Bars or Screen Plate Trapezoidal cage bars are of replaceable, ensuring freedischarge. Screen plates are made from abrasion resistantsteel. Selection of cage bars or screen plates depends on application.

Breaker Plate Replaceable abrasion resistant steel, depending on requirement.  

Cage Adjustment Cage assembly can be easily moved by a ratchetwrench and worm gear assembly either towards oraway from the path of crushing rings. Adjustment which can be made while the granulator is in operation, provides control over the product sizewithin permissible limits. The cage hinge bearing is so located that in any adjusted position all parts of cage face are practically equidistant from the rotor assembly. This ensures even wear.  

Tramp Iron Pocket  Tramp iron and uncrushables are prevented from continuing around and back into the crushing zone by a heavy deflector plate. The debris is collected in a pocket and removed from access door

Bearing Heavy duty double row spherical roller bearings with cast steel split type bearing housings with labyrinth type seals.  

Lubrication Grease lubrication for small and medium size granulators. Oil splash lubrication system for bigger models.  

Drive  

Direct coupled drives are recommended. For smaller models V- Belts drive may be used.
