Description
Technical field:
The utility model relates to cement processing grinding technique field, is specifically related to a kind of novel vertical mill pressure roller.
Background technology:
In recent years China's new dry cement production technology develops rapidly, and wherein, Vertical Mill technology and equipment improve thereupon.The cement production enterprise of quite a few new construction, use Vertical Mill to become common practise, the Vertical Mill that domestic and international producer manufactures puts into production, and obtains good energy-saving effect.Cement industry uses Vertical Mill can grind coal dust, cement slurry, cement ore ground-slag and precrushing grog, can be divided into coal mill, raw mill, cement grinding mill, slag mill, pre-comminution by its ground prod.Because the granularity of grinding material, moisture, form are different with the difference of grindability and the technical requirement of product, Vertical Mill structure has multiple pattern.In use, its vulnerable part is subject to the abrasion of material to Vertical Mill, as mill, grinding roller liner plate, spout ring, inner walls powder concentrator vertical shaft, fan blade and outlet airduct etc.But the wear out failure of mill, grinding roller liner plate working surface most serious of all, comprises uniform wear, uneven wear, peels off and the performance pattern such as cracked.The change of its shape that mill, grinding roller liner plate cause because of wear out failure, makes the mill efficiency of Vertical Mill decline, and causes the change of output reduction and product quality.Because of the reduction of mill efficiency, power consumption can be made to increase.Conventional selection is that commute mill part is repaired, namely commute mill part entirety carries out changing or carrying out built-up welding at the working surface easily grinding part, if there is casting residual stress in grinding roller, the crackle then produced during built-up welding is easily expanded, and the time changed needed for wearing plate when repairing is longer, affects production efficiency at every turn.
At present, grinding roller generally adopts the cast such as rich chromium cast iron, alloy to form, when the material that grinding abrasion is stronger, wearing and tearing are very fast, the life cycle that can not meet the shortest 1 year ensures, too fast wear liner can cause mill running rate to reduce, and metal wastage strengthens, and maintenance cost increases, therefore, be badly in need of adapting to various material, grinding roller liner plate that anti-wear performance is good.Wear-resistant ceramic is a kind of material based on aluminium oxide, other rare metal oxide additional is solvent, form through high temperature sintering, be widely used in the plant equipment such as the conveying system of the enterprises such as thermoelectricity, smelting, cement, pulverized coal preparation system, ash discharge, dust pelletizing system, such as use in loading mechanization magazine-less system, the position easy to wear such as version, bucket wheel circular arc wearing plate is reclaimed at stock guide, blanking in concrete position.In actual applications, often make according to the shape of grinding roller the liner plate matched, and be bolted, complete the fixing of liner plate.But in use, when roller surface serious wear needs to change pressure roller in time, traditional pressure roller adopts screw rod bolt to fix, and dismounting and change bothers very much, and the grinding alloy wear-resisting coefficient that surface adopts is low, and service life is short.
Utility model content:
The purpose of this utility model is to provide a kind of novel vertical mill pressure roller, its structure is simple, design ingenious, the mode of spacing clamping is adopted to be fixed, join an outside fixed disk, realize removing and installing efficiently, and surface adopts diamond dust to coordinate Buddha's warrior attendant salient point to grind, and substantially increases service life.
In order to solve the problem existing for background technology, the utility model is by the following technical solutions: it comprises rigid bearing, pressure roller clamping dish, clamping locating part, metal alloy clamping frid, ceramal liner plate, diamond dust grinding layer, Buddha's warrior attendant salient point, the outside of described rigid bearing is fixed with pressure roller clamping dish, the arranged outside of pressure roller clamping dish has several clamping locating part, clamping locating part be connected in metal alloy clamping frid, the arranged outside of metal alloy clamping frid has ceramal liner plate, the arranged outside of ceramal liner plate has diamond dust grinding layer, the outer ledge of diamond dust grinding layer is provided with the Buddha's warrior attendant salient point of half-turn.
The beneficial effects of the utility model: its structure is simple, designs ingenious, adopts the mode of spacing clamping to be fixed, join an outside fixed disk, realize removing and installing efficiently, and surface adopts diamond dust to coordinate Buddha's warrior attendant salient point to grind, and substantially increases service life.
