3. Preamble to the description: The following specification particularly describes the invention and the manner in which it is to be performed.
FIELD
The present disclosure relates to the field of refining equipment. More particularly, the present invention relates to paper pulp refining equipment.
BACKGROUND
Refining the fiber from the pulp or slurry is a vital process that has to be performed in the paper and pulp industry. Said refining acts as the “backbone” unit process during said paper-making process, wherein the repeated cycles of shear and compressive forces are applied or beating of pulp fibers is performed in an equipment called refiner, which is enabled by the use of rotor and stator configuration with the help of bars and grooves. Wherein said bars and grooves as required for said refining operation process are mounted or created on the surface of refining discs or plate segments in order to define the refining elements of said discs or segments. Further, said bars and grooves can be formed in small regions or clusters called a sector in order to form a segment and from said number of segments to form said disc or plate. In the case of said disc formed of said sectors of said segments, the number of said segments required to form said disc depends on an angle of said sector or said segment in conventional design said sector angle (A) observes to be 30º to 40º that is required to reduce because as small as said sector angle (A) increases the number of said sectors, as required in order to form said disc of said segment, which increases said flow channel that is observed in conventional design as 12 in order to increase refined material flow over said disc which can be ultimately responsible in order to increase the efficiency for said refining process. Further, a design of said grooves of said refiner disc also plays a vital role in the processing of said refining operation of pulp or slurry, wherein said grooves provide passages through which material moves in a radial plane between the surfaces of said disc. The material also moves out of the radial plane from the grooves and over said bars. As the depth of said groove increases the capacity of material flow increases over said groove in order to provide a more open area to refine said material, whereas there can be adverse effects of side more depth of said groove in the form said refiner disc weakening as said grooves reduces the material or strength required to sustain said refining operation load. Therefore said grooves shall be designed dynamically to provide an optimum output in accordance with the input material. Furthermore, said ribs are also a vital element that nurtures said fiber in accordance with said final output required for the intended application. Wherein said ribs can be of various designs and sizes that change with respect to application and fiber size intended to process and feed to said refiner disc. Said ribs not only decide the type of said refiner disc to process but also decide the material to be fed and required to be changed or replaced as per the material type. Also, said ribs are responsible for a cutting edge length (CEL), and a specific edge load (SEL) as required to process the material in order to convert in the intended fibre. Whereas said ribs are required to design in accordance with the parameter which includes but not limited to the fiber type, the material of input slurry, output required, capacity, etc., and required to be changed after processing said material, also in case of said uniform rib the possibilities of escaping any different material or unintended fiber loss exists for example a short fiber input material intended to feed in a disc that designs for a long fiber then there are more probabilities that said short fiber can be damaged or not processed and expelled as a rejected material that leads in the fiber loss. Furthermore in case if it exists that mixed kind of input fed that is difficult to categories in conventional design it’s been difficult to process said mixed type of input material, which can lead to sever loss of fiber or provide inappropriate input to further process, wherein the output of said refining process considered as input.
However, in conventional design said disc form of said segment and said segment from of said sector with said ribs and said grooves assembled as cast or configured with different configuration technique as a heavy element that required to configured with a rotating element that intended to rotate at the higher speed at full capacity to perform said action of refining operation in order process the inputted material. Moreover, said heavy configuration of said disc and rotating element causes adverse fluctuation or vibration during operation that leads into a fatigue failure, forming cracks, increases wearing, and misalignment of part and other ancillaries which further can lead to a catastrophic failure for said configuration of said disc with said rotating element that also reduces the life of said refining element. Said configuration or said disc with said rotating element can be achieved by means of a lug, or a peripheral diameter of said disc, and other non-refining areas of said disc, which further increases the weight of said refiner disc and increases the power requirements to perform said refining operation of feed material as well as requires more strength of said rotating element in order to perform the intended action which increases the power consumption and energy requirement to process said fed material.
Hence, there is a technological gap that exists that is required to be fulfilled by employing a more dynamic disc design that can handle all kinds of material with a lower weight to achieve optimum performance and alleviate the above-mentioned drawbacks.

SUMMARY
The present invention envisages a refiner disc comprising; a plurality of a segment configured with each other to formulate said refiner disc. Further, a plurality of a sector can be configured with each other in order to articulate said segment from a sector angle. Wherein, a series of bars can be configured with a base in order to form said sector and a groove. Whereas a relief zone can be configured with a zone of said bars and sectors to process the input material or slurry which includes but not limits to a short fiber slurry, long fiber slurry, mixed type of slurry, hardwood slurry, softwood slurry, etc. into a refined fiber by means of said refiner disc.

DETAILED DESCRIPTION
The present invention envisages a refiner disc (100) comprising a number of segments (101) and said segment (101) comprising a number of sectors (102). Said sectors (102) comprise a series of bars (111) and a groove (112) directed at a specified angle at a specified distance in a manner to process the input material or slurry into a refined fiber. As shown in figure no.01 a slurry or material to refine fed from a central end (113) wherein said disc (100) can be configured with a rotating member by means of a central fixing means (110) in order to feed said slurry directly into an inner zone (106) wherein said bars (111) can be arranged in an inlet bar pattern (108) with more in length than an outer zone (105) in a ratio ranging from which include but not limits to 3:2 in order to refine long fibers material from said slurry in the first aspect and direct said refined slurry for long fibers at an angle (C) which include but not limits to ranging from 4 degrees to 15 degrees of said inlet bar pattern (108). Wherein a relief zone (104) can be provided between said inner zone (106) and said outer zone (105) typically of size ranging which include but not limited to at least 5 to 8 unit in order to form an optimum slurry layer as required in order to enhance the refinement quality of said fed material. Further said processed material from said inner zone (106) passed to said outer zone (105) by means of said relief zone (104) in order to refine said material for short fibers by means of an outlet bar pattern (107) more specifically that can consist from a fine bar of thickness which include but not limits to at least 1 to 3 unit and groove size ranging from 2 to 4 unit configured in area of ratio with respect to said long zone (106) ranging from 40 :60 and arranged at an angle (D) ranging from 5 degrees to 15 degrees in order to expel said refined material in a directional manner without germinating any turbulence or backlash at a peripheral end (119) most preferably under centrifugal force action from said central end (113) to said peripheral end (119). Wherein said disc (100) can be configured by means of a flexible peripheral fixing means (109) that can be modified in accordance with a peripheral adapting means without changing the size or cutting edge length (CEL), specific edge load (SEL) and overall area of said disc (100) in order to induce the better interchangeability for said disc (100) and eliminate requirement of fixing edge or fixing collar or additional area as required to formulate configuration with said fixing adapting means that reduces the self-weight of said disc (100). Whereas a pair of said inner zone (106) and said outer zone (105) configure in one above manner to form said sector (102) and with said angle of inlet bar pattern C and said outlet bar pattern D can be of same or variable in configuration. Furthermore said sector (102) can be configured with adjacent another similar or different said sector (102) by means of a vertical relief zone (103) in order to form said segment (101) and swiftly process the fed material. Whereas an angle of said sector angle (A) defines the numbers of said sector (102) required in order to form said segment (101) as said sector angle (A) decreases the number of said sectors (102) required to form said segment (101) increases said vertical flow channel (103) that further enhances overall refining operation and material flow area over said disc (100) that increases the cutting edge length (CEL) and material flow, reduces specific edge load (SEL), in order to ultimately boost efficiency as well as the efficacy of said disc (100) and said refiner. In one of the embodiments of the present invention said sector angle (A) can be of size ranging 8º-16º-24º and most preferably can be 10º-15º-20º in order to create 12 to 52 numbers of said vertical relief zone called as flow channels (103) as the number of said flow channels (103) increases the more will be the flow of refined material occurred across said disc (100) increases output for said disc (100).
In another embodiment as shown in figure no. 02 said segment (101) comprising a pair of said sector (102) that can be separated vertically by means of said flow channel (103) wherein said inner zone (106) with said inlet bar pattern (108) that can be preferably of coarse type of bar pattern to process long fiber located at said central fixing means (110) of said segment (101) and said outer zone (105) with said outlet bar pattern (107) that is preferably of fine type of bar pattern to process short fibers located adjacent to said peripheral end (109) and separated by means of said relief zone (104). Further, said segment (101) comprises at least two said sectors (102) and an angle made by said segment (101) called said segment angle (B), wherein said segment angle (B) also be at least two times of said sector angle (A). Whereas in one of the embodiments of the present invention said sector angle (A) can be as small as size ranging 8º-16º-24º and most preferably can be 10º-15º-20º in order to increase the number of said sector (102) required to form said segment (101) that will increase the refining operation area for said disc (100) by means of an increase in cutting edge length (CEL) and material flow, reduces specific edge load (SEL), for said disc (100). Further, the increase in the number of said sectors (102) also increases the number of said flow zone (103) in order to increase the discharge of said refined material from the increased number of said flow zone (103). Wherein one of the preferred embodiment of the present invention said number of flow zone (103) with respect to said angle (A) ranging 8º-16º-24º and most preferably can be 10º-15º-20º shall be up to 12 to 52 in numbers. However, the increase in said number of sectors (102) also increases the number of said relief zone (104) for said segment (101) as well as said disc (100) that assist in better refinement of said slurry which improves the quality of final refined material and enhances the efficacy of said refinement system. Moreover, said peripheral fixing means (109) can be configured or prepared as cast with at least two number of said segments (101) or at least at three sites of said disc (100), most preferably facing opposite to each other or located at 90, 120, 180, 240, 270 degrees with respect to complete said disc periphery (119), wherein said localized peripheral fixing means (109) compensate complete fixing or mounting ring or mounting collar as required for fixing of said peripheral end (119) within the adapting means in case of peripheral fixing is required. Said localized peripheral fixing means (109) fix said peripheral end (119) by local support only instead of a complete ring or collar that optimizes the material as required and reduces the weight of said disc (100) without affecting adversely on said refining operation area of said disc (100) and decreasing the rotational load and the power requirement as required to rotate said disc (100).
In another embodiment as shown in figure no. 03, a rib section (122) comprising a series of said number of bars (111) and said groove (112) joined with a base by means of a root radius (116).
