Description
Technical field
The present invention relates to a kind of semi-autogenous mill composite liner of high abrasion.
Background technology
In recent years, grinding machine manufacture and design development rapidly, trend maximizes, large-scale Semi-Autogenous, ball mill is widely applied in each ore dressing plant.Because large-scale semi-autogenous mill barrel diameter is large, feed preparation unit size and ore grinding steel ball are all larger, large to the impact of lining board of grinder, and wear liner is very violent.Liner plate is short service life, and the replacing time is long, not only waste a large amount of human and material resources, and operation rate is low.
Current large-scale semi-autogenous mill generally adopts alloy cast steel liner plate, mainly has following problem: 1. liner plate hardness is lower, and wearability is poor, and service life is short; 2. metal backing heaviness, single-piece 2-3 ton, is prone to making defect, easily splits, and liner plate uses just had part liner plate cracked in 1～2 week, needed to shut down maintenance and changed; 3. metal backing heaviness, bolted difficulty, easily loosening, cause bolt hole to leak ore pulp, the bolt hole of the grinding mill barrel that weares and teares when serious; 4. metal backing installation, dismounting and maintenance are all pretty troublesome, and the labour intensity of workman's maintenance is large, affects production efficiency.
Summary of the invention
Object of the present invention aims to provide a kind of high abrasion, shock-resistant, long service life, the rubber combined liner plate of large-scale semi-autogenous mill antifriction metal (AFM) that lightweight, energy consumption is low.
Object of the present invention realizes in the following manner:
A kind of semi-autogenous mill composite liner structure of high abrasion is mainly made up of liner plate, lifting strip, T-shaped bolt, bowl grommet type seal, bowl-type rubber pad circle, spring washer and hex nut.Liner plate laminating barrel inner side, lifting strip is pressed between two liner plates, in the T-shaped groove of T-shaped bolt sleeve below lifting strip and by bowl grommet type seal, bowl-type rubber pad circle, spring washer and hex nut, lifting strip and liner plate is fastened on barrel inner side.Liner plate and the lifting strip way of contact adopt V-structure, and contact area is large, and closely, fixation is reliable, good seal performance for liner plate and grinding mill barrel laminating.
Described liner plate and lifting strip all adopt antifriction metal (AFM), rubber, general steel plate to be composited.Antifriction metal (AFM) is placed on the violent position of wear liner; Rubber works the metal derby that is adhesively fixed, can buffer portion impulsive force while work simultaneously, and protection antifriction metal (AFM) and cylindrical shell, liner plate impact resistance is improved; General steel plate is mainly used in the effect of fixing liner plate.Antifriction metal (AFM) hardness high (more than HRC55), anti-wear performance is good, is made into metal derby, and heat treatment quenching degree is good, even tissue, impact flexibility is good, and quality is easily controlled.
Described lifting strip antifriction metal (AFM), lifting strip antifriction metal (AFM) is designed to fritter, and section configuration design is optimized design according to wear law, bevelling, both sides, top, bottom design becomes cambered surface, ensures, under the precondition of allowance for abrasion, to reduce the weight of antifriction metal (AFM) as far as possible.Lifting strip antifriction metal (AFM) design handle, plays kiss-coating effect, guarantees that lifting strip antifriction metal (AFM) and lifting strip rubber are bonding firmly, is also convenient to the operation that lifts of workman's manufacturing process simultaneously.Lifting strip antifriction metal (AFM) is designed to some fritters, inclined-plane, groove and boss design are carried out in side, strengthen the adhesive strength between lifting strip antifriction metal (AFM) and rubber, play the effect of transmitting shock loading simultaneously, guarantee that lifting strip antifriction metal (AFM) and lifting strip rubber are bonding solid and reliable, prevent that use procedure lifting strip antifriction metal (AFM) seam crossing from forming circulation, accelerated wear test simultaneously.
Described liner plate antifriction metal (AFM), section profile is optimized design according to wear law, and abration position thickening design, increases wear-resisting nargin and impact resistance, not easily broken.
The present invention's beneficial effect is compared with prior art:
Semi-autogenous mill composite liner of the present invention is by special antifriction metal (AFM), rubber and general steel plate compression molding, antifriction metal (AFM) is positioned over ore grinding and utilizes the position of best results, general steel plate easily processing is installed fixing for bottom, rubber is for middle, play bonding, cushioning effect, this design combines the optkmal characteristics of high-performance abrasion-proof metal, rubber and general steel plate, thereby obtains the product of high comprehensive performance.Composite liner working surface is antifriction metal (AFM), and surperficial shock resistance, wear-resistant ability are both provided, and brings into play again the contribution of rigidity working surface to grinding efficiency, and grinding machine disposal ability can not be affected and maybe can ignore.Composite liner antifriction metal (AFM) anti-wear performance is good, and long service life is the more than 1.5 times of common alloy lining.Composite liner weight is alleviated, and is 1/2～2/3 of common alloy lining, cost-saving, has effectively reduced the load of equipment, saves energy consumption, has alleviated workman's labor intensity simultaneously.
