Technical Field
The utility model relates to a semi-autogenous mill equipment technical field especially relates to a novel wear-resisting lining board for semi-autogenous mill.
Background
A semi-autogenous mill is a rotary type device used to grind hard rock ore after it has been processed by a crusher and before it enters a ball mill. The cylinder liner plate of the semi-autogenous mill provides a replaceable wear-resistant surface for the semi-autogenous mill, and simultaneously grinds materials in the semi-autogenous mill and discharges the ground materials at a discharge end. The lining plate used on the semi-autogenous mill is an important part on the semi-autogenous mill, and is mainly used for protecting the cylinder body of the semi-autogenous mill from direct impact and friction of grinding media and materials, simultaneously lifting the materials to crush and grind the materials, and the materials and the grinding media are lifted to a certain height by the rotation of the semi-autogenous mill to generate impact action by free fall and grinding and stripping action by mutual friction among the materials, so that the materials are crushed and ground.
At present, the connection between the lining plates in the cylinder body of the semi-autogenous mill is generally made by conventional splicing, and the semi-autogenous mill runs for a period of time, because the impact resistance of the lining plates is poor, the wear resistance is not enough, the abrasion of the materials to the lining plates increases the gap between the lining plates, the materials can fall between the lining plates, a rotational flow is formed between the gaps of the lining plates, so that the circumferential abrasion of multiple parts of the cylinder body of the semi-autogenous mill is caused, the safe and stable running of the semi-autogenous mill is influenced, and the service life of the cylinder body of the semi-.

Detailed Description
The following describes embodiments of the present invention with reference to the accompanying drawings.
Fig. 1 is the utility model relates to a novel wear-resisting schematic diagram of welt embodiment for semi-autogenous mill, as shown in the figure, the utility model provides a novel wear-resisting welt for semi-autogenous mill, including the body, the body includes bottom plate 1 and the promotion boss 2 of being connected perpendicularly with bottom plate 1, and the left end lower part of bottom plate 1 forms the lower flange 3 that extends left, and the right-hand member upper portion of bottom plate 1 forms the last concave plate 4 that extends right, and the last concave plate 4 and the lower flange 3 of adjacent bottom plate 1 are connected, realize the zonulae occludens of two adjacent welts, avoid producing the gap because of wearing and tearing between two welts that are connected.
The upper portion of lower flange 3 is equipped with butt joint recess 5, goes up the lower part of concave plate 4 and is equipped with and butt joint recess 5 assorted butt joint arch 6, and butt joint arch 6 joint makes lower flange 3 and last concave plate 4 be connected stably in butt joint recess 5, and difficult slip produces the dislocation. The butt joint groove 5 is provided with a first connecting hole 7 penetrating through the lower convex plate 3, the butt joint protrusion 6 is provided with a second connecting hole 8 penetrating through the upper concave plate 4, the second connecting hole 8 corresponds to the first connecting hole 7, the first connecting hole 7 and the second connecting hole 8 are threaded holes, and after the upper concave plate 4 of the adjacent lining plate is lapped on the lower convex plate 3, the lining plate is fixed on the cylinder wall by using a connecting piece to penetrate through the first connecting hole 7 and the second connecting hole 8.
Fig. 2 is the utility model relates to a novel wear-resisting semi-autogenous mill is with side view of the wear-resisting bead of welt, as shown in the figure, 1 medial surface of bottom plate is equipped with the wear-resisting bead 9 of side sawtooth form, strengthens welt bottom plate 1's shock resistance, improves welt bottom plate 1's wearability. Promote boss 2 and be equipped with two, the both sides face that promotes boss 2 is the wave surface, the concave-convex part on wave surface can cushion the impact force that the material was thrown to on promoting boss 2, the reinforcing promotes boss 2's wear resistance, the probability that promotes boss 2 by pounding has been reduced, promote boss 2's wavy surface slope setting, make the material can be promoted 2 effectual promotion and by the higher bigger potential energy that obtains of throwing, when the material falls the bulge that promotes boss 2 wavy surface, the bulge is little with the area of contact of material, great impact force has to the material, the improvement is to the crushing efficiency of material.
