Description
Technical field
The utility model belongs to ore deposit rock field of crushing equipment, relates to a kind of disintegrating apparatus for ore deposit rock, more particularly, relates to a kind of wear-resisting type high-pressure roller mill.
Background technology
High-pressure roller mill is the novel energy-conserving milling equipment of the eighties appearance in mid-term, is that cement grinding and metallic ore are pulverized one of intermediate equipment in link, is the key equipment that can realize how broken few mill, can significantly reduce energy resource consumption.High-pressure roller mill has obtained applying greatly in cement field, but the wearing and tearing due to roll surface, in the pulverizing of the ore of metal mine still in the starting stage, adopt the roll surface of hard alloy stud, greatly improve the abrasion resistance of roll surface, made high-pressure roller mill obtain breakthrough progress in the pulverizing of the ore of metal mine.When powder ore, in order to improve roll-in efficiency, prevent that in cavity, material is overflowed, must with two side shields, surround a cavity for sealing relatively in the side of two roller shells.When roller shell rotates with linear velocity 1～3 meter per second, two side shields are tightly pressed on roller shell side, cause the wear extent of roller shell and side shield all very large, due to roller shell adopt intensity and hardness all higher material make, size is large (roller shell external diameter can reach 2 meters) also, Heavy Weight (roller shell substance reaches 30 tons), after wearing and tearing, on-the-spot being difficult to repaired.In order to improve the wearability of roller shell, general method is to adopt wear resistance electrode to carry out built-up welding to the end face of roller shell end and side at present.Due to overlaying surface out-of-flatness, and be difficult to processing, must leave gap in the side of side shield and roller shell, caused material in cavity to overflow.Due to the edge effect between ore and rod cover end face in the course of the work, the overlay cladding of end face is easily come off, and further cause end face overlay cladding to come off, thus the coming off of hard alloy stud of causing roll surface, be only 2～3 months its service life, and equipment operation rate reduces greatly.
China Patent No.: 201120126820.7, open day on 09 21st, 2011, this utility model relates to a kind of Novel high-pressure roller mill, comprise feed arrangement, articulated frame, movable roll, stationary roll, pressure roller body and roller shell, described articulated frame is equipped with two covers with the pressing roll mechanism of stud roll surface, one of them pressing roll mechanism is stationary roll, the movable roll of another pressing roll mechanism for can horizontal direction moving back and forth; Be positioned at roller shell end face and be provided with abrasion-proof composite plate, abrasion-proof composite plate and multi-disc retainer ring are combined into a smooth circular ring structure by wedge surface and bayonet socket; The roll surface of described pressure roller body evenly arranges some hard alloy studs.This utility model beneficial effect is: the solution scale of construction of equipment while having reduced maintenance, makes the overhaul of the equipments time greatly reduce, reduce the cost of overhaul; Can prevent the coming off of hard alloy stud of roll surface; Improved the boundary effect between ore and rod cover end face, and wear extent is little, has extended roller shell service life; The adjustable feed arrangement with parallel four-bar linkage, can guarantee that charging is unimpeded smoothly.But the side shield of the patented product often needs to change in use, and the life-span is short, and factory needs longer roller mill of life-span now.
China Patent No.: 200910116979.8, open day on 07 20th, 2011, the patent document that a name is called high-pressure roller mill for metal ore is disclosed, belong to the equipment of a kind of crushing metal ore deposit rock material.It is comprised of critical pieces such as frame, high pressure roller, universal drive shaft, reductor, feed adjusting device, hydraulic control system, electric-control systems.In frame, horizontal Tile is provided with two cover high pressure roller devices, and its type of drive is that motor is connected with high pressure roller through universal drive shaft through reductor again; Every cover high pressure roller is equipped with separately independently drive unit, and wherein a set of high pressure roller is fixed, another set of can slip in the horizontal direction; Its side at action roller is provided with the oil cylinder of exerting pressure; In the both sides of high pressure roller end face, self-adapting float side shield is installed.This machine be a kind of efficient, energy-conservation, consumption reduction disintegrating apparatus, there is significant economic benefit.This patent is by the form of self-adapting float side shield, to reduce the wearing and tearing of side shield, but this form is not only controlled complexity, and manufacturing cost is high, and not raising of wearability, and what increase service life is few.
Now in the urgent need to developing a kind of new roller mill, be, the life-span of side shield is strengthened greatly, and require to control conveniently, cost is low.
Summary of the invention
The problem that 1, will solve
Life-span for the side shield of existing roller mill is short, and controls trouble, the problem that cost is high, the utility model provides a kind of wear-resisting type high-pressure roller mill, and not only baffle plate is wear-resisting, and the parts on baffle plate can be changed, only need to change frayed parts, easy to operate, cost-saving.
2, technical scheme
For addressing the above problem, the utility model adopts following technical scheme.
A kind of wear-resisting type high-pressure roller mill, comprise feed arrangement, movable roll, stationary roll, pressure roller body and roller shell, roller shell end face is provided with baffle plate, described baffle plate is substrate body, also comprise the first wearing plate, antifriction alloy post and the second wearing plate, the first described wearing plate and the second wearing plate are all arranged on a side of substrate body, and the first wearing plate is fixed by screws in the top of substrate body, and the second wearing plate is fixed by screws in the bottom of substrate body; On the first described wearing plate and the second wearing plate, be all provided with strip dovetail groove; Described antifriction alloy post is arranged in dovetail groove.
