Abstract
The utility model belongs to ore dressing polishing crushing technology field, relates generally to a kind of semi-autogenous mill liner plate.A kind of semi-autogenous mill proposed has with the center of the body upper surface of liner plate to lift the trapezoidal protrusion of steel ball when in use；The trapezoidal protrusion is set along body length direction；The trapezoidal protrusion is up-small and down-big structure；The body of trapezium structure is formed between the trapezoidal raised and body upper surface using arc transition；The upper surface of the body is additionally provided with stiffener plate；The stiffener plate is along the multiple of body length direction setting；The lower face of the body is provided with horizontal reinforcing plate and longitudinally reinforced plate；The horizontal reinforcing plate, longitudinally reinforced plate be connected as one with the body lower face of body is divided into it is latticed.The utility model reduces deformation of the liner plate when lifting steel ball, improves the impact flexibility of liner plate, adds service life.
Description
Technical field
The utility model belongs to ore dressing polishing crushing technology field, relates generally to a kind of semi-autogenous mill liner plate.
Background technology
Mineral Processing Enterprises scale is continuously increased at present, its ore grinding equips large-scale semi-autogenous mill and is increasingly becoming trend：And at present partly
The problems such as autogenous tumbling mill liner plate entirety using effect is poor, liner plate deformation, fragmentation causes liner plate whole service life very short, how to increase
The whole service life of lining plate is the major issue that current liner plate needs to solve.
Utility model content
The purpose of this utility model is to propose a kind of semi-autogenous mill liner plate, can change liner plate using process by
Power state, reduces liner plate fracture, metaboly, increases the service life of liner plate.
To achieve these goals, the utility model is realized using following technical scheme：
A kind of semi-autogenous mill liner plate, the center of the body upper surface of the liner plate have to lift steel ball when in use
Trapezoidal protrusion；The trapezoidal protrusion is set along body length direction；The trapezoidal protrusion is up-small and down-big structure；Institute
State the body for using arc transition to form trapezium structure between trapezoidal raised and body upper surface；The upper surface of the body is also set
It is equipped with stiffener plate；The stiffener plate is along the multiple of body length direction setting；The lower face of the body is provided with
Horizontal reinforcing plate and longitudinally reinforced plate；Horizontal reinforcing plate, longitudinally reinforced plate and the body is connected as one this
The lower face of body is divided into latticed.
The thickness of the body is 320-350mm.
The transverse direction reinforcing plate, the thickness of longitudinally reinforced plate are 25-40mm.
The utility model proposes a kind of semi-autogenous mill liner plate, the trapezoidal protrusion designed by body upper surface, to
Steel ball is lifted during liner plate use, since semi-autogenous mill steel ball hoisting depth is higher, the impact force that liner plate is born is very big, sets
Horizontal reinforcing plate, longitudinally reinforced plate at body back are supported liner plate, and subtract while liner plate lifts steel ball height
Deformation of the liner plate when lifting steel ball is lacked, has improved the impact flexibility of liner plate, add service life.
Brief description of the drawings

Fig. 2 is the side view of Fig. 1.
The rearview of body in Fig. 3 the utility model.
In figure：1st, body, 2, stiffener plate, 3, trapezoidal protrusion, 4, horizontal reinforcing plate, 5, longitudinally reinforced plate.
Embodiment
The utility model is illustrated with reference to the drawings and specific embodiments；
A kind of semi-autogenous mill liner plate as shown in Figure 1 and Figure 2, the center of 1 upper surface of body of the liner plate have to
Trapezoidal raised the 3 of steel ball is lifted during use；Described trapezoidal raised 3 are set along 1 length direction of body；Described trapezoidal raised 3
For up-small and down-big structure；The sheet of trapezium structure is formed between described trapezoidal raised 3 and 1 upper surface of body using arc transition
Body；The thickness of the body 1 is 320-350mm；The upper surface of the body 1 is additionally provided with stiffener plate 2；The reinforcing rib
Plate 2 is along the multiple of body length direction setting；In the embodiment, the stiffener plate is two；The lower end of the body 1
Face is provided with horizontal reinforcing plate 4 and longitudinally reinforced plate 5；The horizontal reinforcing plate 4, longitudinally reinforced plate 5 connect with the body 1
Be connected in one the lower face of body is divided into it is latticed；The transverse direction reinforcing plate 4, the thickness of longitudinally reinforced plate 5 are 25-
40mm。
