grinding rolls/ table liners | shri balaji

SBIPL manufactures and supplies Ni-Hard grinding rollers and Bull ring segments in the below specification. The combination of Ni-Hard rolls and High Chrome table liners is still holding a significant market share as the cheaper cast iron core is easier to machine. BIPL manufactures the same through the bi-metallic technology in the below grade.

Over the years, we have studied the pattern of changing coal quality in thermal plants in India, and with it, the reducing life of mill internals, and associated difficulties. In order to overcome the same, we have after continuous R&D, developed the 3rd generation of High Performance Grinding Rolls and High Performance Bull Ring Segments. Please see below the salient features of this latest, High Performance Grinding Rolls and High Performance Bull Ring Segments HIGH PERFORMANCE GRINDING ROLLS The High Performance Grinding Rolls have hard carbide tips which are mechanically fixed to roll mould, with more than adequate strength in such a fashion that these remain in location, through out its life cycle. The Carbide tips are first separately cast with an alumina grain cake inside the tip body. These tips are then arranged in a suitable pattern to the roll mould (metallic or sand) and further bound by a parent body of SG Iron metal. The intermittent gap maintained between adjacent tips, ensure gripping of coal particles and avoid material slippage. This ensures excellent grinding efficiency throughout the life cycle of the rolls. Mechanical Properties:- They are suitably heat treated to achieve high hardness (in the range of 59-66 HRc) and offer excellent wear resistance. Photo and sketch of above HIGH PERFORMANCE BULL RING SEGMENTS The bull Ring Segment metallurgy is specially developed to give excellent physical, mechanical and metallurgical properties. It is formed by casting a similar alumina grains cake in a high chromium material. Heat treatment is done to achieve microstructure of chromium carbides in matrix of tempered martensite. Special heat treatment controls Retained Austenite below 5%, giving hardness in the range of 59-66 HRc. This allows Bull Ring Segments to be used even up to 45 mm wear without losing of grinding efficiency, maintaining consistently high mill out put and coal fineness.

coal mill, gypsum mill, clay mill, etc. | pfeiffer mps mills

Highest flexibility with constant product quality, individually conceived, suitable for a variety of applications, undergoing constant development: with a number of more than 2800 mills sold, the MPS vertical mill is our proven allrounder. It can be used for the grinding of coal, petcoke, clay, limestone, quicklime and many other materials no matter how different their grindability and abrasiveness may be or whatever fineness or drying degree is required. The MPS mill also grinds, dries, calcines, and classifies gypsum without any problem, all in a single machine, for any fineness requested and considering individual requirements. The MPS vertical roller mill - built to last, reliable and energy-efficient - is the optimum solution when it comes to performing several process steps in one unit.

High drying capacity, short dwell time of the material to be ground, and remote control of grinding pressure and classifier rotor speed ensure a fully automatic operation of the MPS mill even with varying raw material characteristics.

Three stationary grinding rollers roll on a rotating grinding table. The material is drawn in between the rollers and grinding table and ground by pressure and shear. The required pressure forces are produced by a hydropneumatic tension system. After being rolled over by the rollers, the material is conveyed to a stationary nozzle ring due to the rotation of the grinding table. Gases (air or hot gas) flow through this nozzle ring, take up the ground and dried material and convey it to the classifier where it is separated by the rotating wheel (rotor) into grits and fines. The grits fall back into the grinding zone whereas the fines leave the classifier with the gas flow for being separated in cyclones or a filter.

Depending on the abrasiveness of the material to be ground and areas to be protected, different wear materials are used on our vertical roller mills. The grinding elements are primarily made of alloy cast iron as per DIN 1695, hardfaced cast iron or composite materials with high-chromium inserts in ductile base materials. The housings and other mill components are protected against jet wear with highly wear-resistant steel plates or hardfaced composite plates. Components which are specifically exposed to wear like gas outletducts have additional ceramic liners. All this is for optimum protection and short maintenance shutdown.

The highest wear occurs on the wear parts of the grinding elements as is the case with any type of vertical mill. Therefore, ease of replacement and regeneration is a major feature of the mill. With our proven Lift-and-Swing System, wear parts can be replaced rapidly through one single maintenance door. The grinding rollers and grinding table segments are driven to the maintenance door with the maintenance drive and are swung out of the grinding area. As a result maintenance downtime is reduced and work is easy and safe.
