Description

Combined type modified MC nylon lining board of grinder assembly

Technical field

The present invention relates to a kind of lining board of grinder, particularly, relate to a kind of combined type modified MC nylon lining board of grinder assembly.

Background technology

In industries such as metallurgy, iron and steel, chemical industry, the application of grinding machine is indispensable, and the analysis and research of its efficient, cost are caused people's attention more, and is especially all the more so in the current epoch with keen competition.Efficient, the cost of research grinding machine just must be analyzed and study lining board of grinder.The high liner plate of cost performance has very big influence (for example in ore dressing process to efficient, the cost of grinding machine, the ore grinding expense accounts for more than 50% of production cost, the wherein only about half of consumption that is used for liner plate and abrading-ball, frotton, second half is used for energy consumption), therefore very meaningful to the research of liner plate.

The grinding machine major part of all size is still adopting metal backing (manganese and spheroidal graphite cast-iron liner plate) now.Metal backing has following shortcoming: the first, and noise pollution is serious; The second, weight is too big, and inconvenience is installed; The 3rd, the life-span is short, and energy consumption is big etc.

Rubber lining and modified MC nylon liner plate had appearred again in recent years.But advantage such as rubber lining has and resistance to wears, and is corrosion-resistant, and noise is little defective such as easily wears out, easily comes off, easily is torn but exist.Existing modified MC nylon liner plate adds multiple additives such as shock resistance auxiliary agent, antiwear assistant, high temperature resistance auxiliary agent respectively in MC nylon, but the properties of product that added too much additive to affect, and its shape is single, can not satisfy application requirements.Therefore, modified MC nylon nylon liner plate is not applied.

Present liner plate type (main material is metal and rubber) mainly contains waveform liner plate, trench liner, flat liner plate, press strip liner plate, ladder lining board, classifying lining board, hemispherical liner plate, convex liner plate etc., and wherein commonly used is ladder lining board, waveform liner plate and press strip liner plate.But every kind of liner plate all has the disadvantage of its existence.For example, flat liner plate is that point contacts with abrasive body, is prone to slip simultaneously, and this has reduced the rate of climb and the hoisting velocity of abrasive body, and efficient is low; The hoisting power deficiency of press strip liner plate, band material is highly inhomogeneous, and is too high as Fruit grinder speed, falls on the liner plate on opposite accelerated wear test after then may making abrasive body throw; The material casting of convex liner plate is too high, and economic performance is bad, because an experience wear just must be changed the monoblock liner plate, therefore seldom uses now; The band material energy force rate convex liner plate of waveform liner plate is also poor, and sliding phenomenon can occur, but it has avoided the too high phenomenon of material casting; Ladder lining board band material is even, band material height uniformity, even after the process wearing and tearing of surface, shape still changes very little, its shortcoming is to exist to grind the dead angle, and noise is too big; The hemispherical liner plate does not have good material casting effect; And the classifying lining board range of application is too narrow.

In view of this, need a kind of novel lining board of grinder of design to overcome the above-mentioned defective of prior art.

Summary of the invention

The purpose of this invention is to provide a kind of combined type modified MC nylon liner plate assembly, to overcome the above-mentioned defective of prior art, this combined type modified MC nylon liner plate assembly is lightweight, wear-resisting, good toughness, shock resistance not only, and can be used in combination according to application requirements, to satisfy the different application requirement of grinding machine.

Above-mentioned purpose is achieved through the following technical solutions: combined type modified MC nylon lining board of grinder assembly, described modified MC nylon is the MC nylon that is added with the nano grade inorganic filler, described inorganic filler is a calcium compound, mica powder, attapulgite, at least a in graphite and the carbon black, described combined type modified MC nylon lining board of grinder assembly comprises a plurality of arcs, each described arc comprises extrados, the arc composition surface of intrados and both sides, be formed with boss on the described intrados between two parties, this boss is divided into the intrados of described arc the first installation arcwall face and the second installation arcwall face of symmetry, the top of described boss forms the boss arcwall face, and the two sides of this boss are the boss engagement sides of symmetry, described first installs arcwall face and second installs arcwall face forms symmetry respectively with two boss engagement sides of described boss first installation gap and second installation gap, described a plurality of arc is covered with this grinding machine inner peripheral wall along the inner periphery direction of described grinding machine, the extrados of each described arc and described grinding machine inner peripheral wall are fitted, and the arc composition surface of each arc engages with the arc composition surface of adjacent described arc, form a plurality of mounting grooves with first installation gap and second installation gap by each described arc, wherein, in ladder press strip and the waveform press strip one is installed separately wherein in any mounting groove in these a plurality of mounting grooves, described ladder press strip comprises ladder press strip installation arcwall face, be positioned at ladder press strip first composition surface of a side, be positioned at ladder press strip second composition surface and the flat top surface of opposite side, be formed with ladder press strip curved working face between wherein said ladder press strip first composition surface and the described flat top surface, be formed with the arc surface that seamlessly transits between described flat top surface and ladder press strip second composition surface, when described ladder press strip is installed in the described mounting groove, described ladder bar is installed arcwall face and is cooperated with the described first installation arcwall face and the second installation arcwall face, fit with the relative boss engagement sides of adjacent described arc respectively in described ladder press strip first composition surface and ladder press strip second composition surface, and one boss arcwall face in described ladder press strip curved working face and the adjacent described arc seamlessly transits; Described waveform press strip comprises waveform press strip installation arcwall face, the waveform press strip curved working face of symmetric arrangement, and symmetrical waveform press strip first composition surface and waveform press strip second composition surface, when described ladder press strip is installed in the described mounting groove, described waveform press strip is installed arcwall face and is cooperated with the described first installation arcwall face and the second installation arcwall face, fit with the relative boss engagement sides of adjacent described arc respectively in described waveform press strip first composition surface and waveform press strip second composition surface, and the described waveform press strip curved working face of the symmetric arrangement of this waveform press strip seamlessly transits with the boss arcwall face of adjacent described arc respectively.
