Abstract
The utility model discloses a ball mill modification welt, ball mill liners are used for protecting the barrel, make the barrel avoid rinding body and material direct impact and friction, the utility model discloses the welt, including the base plate, the arch that sets up on the base plate upper surface and the mounting hole of 1 vertical middle part of base plate setting, the bottom surface of base plate is the plane, and its upper surface extends with contained angle 10 -30 to vertical middle part from both sides gradually to circular arc transition is formed in the middle part. Adopt above -mentioned structure, when the ball mill rotated, the slope of base plate upper surface and the increase of the friction between the rinding body can be supported the rinding body and rise to higher height, because the arch of surface setting both can form the installation to the rinding body, have formed certain passageway again simultaneously, and wear -resisting ball can descend along with the passageway, avoids wear -resisting ball directly with protruding striking, has alleviateed protruding 2 marginal wearing and tearing, has improved life.
Description
Technical field
The utility model belongs to crushing grinding field, is specifically related to a kind of ball mill remodeling liner plate.
Background technology
Ball grinding machine lining board is used for protecting cylindrical shell; cylindrical shell is made directly to impact from abrasive body and material and rub; also multi-form liner plate can be utilized to adjust the motion state of abrasive body simultaneously; to strengthen the pulverization of abrasive body to material; contribute to the mill efficiency improving grinding machine; increase yield, reduces metal consumption.
Ball grinding machine lining board is except protection cylindrical shell; also have impact to the characteristics of motion of abrasive body, for adapting to the requirement of various different operating state and grinding-material, the shape of liner plate and material are also different; when with pulverize for time main; require that liner plate is comparatively strong to the election ability of abrasive body, liner plate should have good shock resistance simultaneously, when with fine grinding for time main; giving prominence to of liner plate is just smaller; just weak to the election effect of abrasive body, impact less, and abrasive action is stronger.Require that liner plate has good anti-wear performance.
Common ball grinding machine lining board, with pulverize for time main, in order to increase the election ability of liner plate to abrasive body, conventional design is arranged by the pit between the crest of liner plate and floor large as far as possible, or contact surface between crest and base plate arranges a lot of small stair, increase friction, but there is certain deficiency in these two kinds of modes, the former arranges the restriction of size by liner plate overall dimensions of pit, and the excessive easy increase crest wearing and tearing frequency of dimple size, reduce service life; The latter arranges small stair, increases friction, and technics comparing is complicated, and production cost is high, not easily promotes the use of.
Utility model content
For solving deficiency of the prior art, the utility model aims to provide a kind of ball mill remodeling liner plate, for improving the election ability of ball grinding machine lining board when pulverizing abrasive body to it, abrasive body is left after material lifting with the rotation of cylindrical shell, material clashes into mutually, form material dnockout, improve crushing efficiency.
For achieving the above object, the utility model adopts following technological means:
A kind of ball mill remodeling liner plate, comprise substrate 1, the installing hole 3 that the projection 2 that upper surface of base plate is arranged and the longitudinal middle part of substrate 1 are arranged, the bottom surface of described substrate 1 is plane, its upper surface extends from the longitudinal middle part of two side direction gradually with angle 10-30 °, and forms arc transition in middle part.
Described angle is 15 °-20 °.
The projection 2 arranged at substrate surface can be quadrangular shape, and also can be semi-cylindrical form, size be determined according to the concrete model of ball mill.
Beneficial effect: the utility model is owing to adopting said structure, when ball mill rotates, friction between the slope of substrate 1 upper surface and abrasive body increases, can support abrasive body and rise to higher height, the projection 2 simultaneously arranged due to surface both can form installation to abrasive body, defined again certain passage, wear-resistant ball can decline with passage, avoid wear-resistant ball directly to clash into protruding 2, alleviate the wearing and tearing to protruding 2 edges, improve service life.
