Abstract
The utility model discloses a double-sided arc T-shaped wave lining board which is applied for the ball mills in the industries such as power plant, metallurgy, mine and building material. The double-sided arc T-shaped wave lining board comprises a lining board body which has a double-sided arc T-shaped section. Because a wave peak of the lining board is a T-shaped wave, the abrasion time of the wave peak is prolonged greatly. The service life of the lining board is prolonged for more than two times. The height of the wave peak satisfies a relationship between a peak height and a steel ball diameter for ensuring a ball throwing rate so that the steel ball is always kept in an optimal lifting height thereby obtaining a function of improving crushing capacity. The operation power consumption of the ball mill is reduced for more than 10% and the electric power is effectively reduced. The loading amount of steel balls is reduced to 80% of that before reconstruction. The consumption expenditure of the steel balls is greatly saved and the economic benefit is remarkable. The yield rate of coal powder is increased for more than 10% based on the original rate.
Description
Technical field
The utility model relates to a kind of ball mill in sector applications such as power plant, metallurgy, mine, building materials, relates in particular to the ball mill abrasion-proof backing block.
Background technology
At present, ball mill has all obtained using widely in industries such as power plant, metallurgy, mine, building materials, existing lining board for ball mill barrel, be generally liner plates such as balancing waveform, waveform, tooth ripple, trapezoidal ripple, the surface configuration of liner plate stationary plane is generally and the suitable curved surface of the surface configuration of cylinder inner surface, when material was ground by abrasive body in cylindrical shell, abrasive body and material rolled to the other end from liner plate one end.Such as China Patent No. is that the utility model patent of CN87213589 discloses a kind of ball mill and discloses a kind of liner plate with the utility model patent of liner plate, this liner plate working face is wavy, wherein, these wavy two troughs and two crests of comprising, this liner plate thickness is more even, but following deficiency is arranged: the one, in the middle and later periods use, the powder process ability drop is fast, the waveform hold facility is poor, needs to increase machine utilization, strengthens steel ball loading capacity and could satisfy the powder process ability; The 2nd, when working, the big grinding machine of this liner plate wave space still has sliding friction between abrasive body and material and the liner plate working face, reduced the service life of liner plate.Be in operation because the defective of structural design causes maintenance workload big, difficult in maintenance, serious cause the improper stoppage in transit of generating set.
The utility model content
The utility model purpose is to provide a kind of abrasion-proof backing block of new structure, and two-sided arc T type ripple is adopted in the liner plate cross section, gives full play to the utilization ratio of liner plate, has guaranteed the safety and economic operation of equipment.
The technical scheme that realizes the utility model purpose is:
A kind of two-sided arc T type ripple liner plate comprises the liner plate body, it is characterized in that: the cross section of described liner plate body is two-sided arc T type ripple.
The utility model compared with prior art has following advantage:
1. because the crest of liner plate is a T type ripple, prolong the wearing-in period of crest significantly, more than the raising twice in liner plate service life, crest height is followed peak valley height and steel ball size relation, guarantee that the toss rate makes steel ball remain on best lifting height, thereby reach the effect that strengthens breaking capacity.Ball mill operation power consumption reduces more than 10%, effectively saves energy; Steel ball loading capacity is reduced to 80% before original transformation, has saved the consumption costs of steel ball greatly, and economic benefit is obvious; Coal dust is exerted oneself and is improved more than 10% on original basis.
2. paddy portion curved design makes steel ball change the slip of curve inclined-plane into by planar slide, effectively improves the autorotation speed of steel ball, the maximum milling efficiency that embodies.
