The specific embodiment
As accompanying drawing, motor 1 drives reductor one 2 runnings, does gyration simultaneously with the mill 6 that reductor one 2 output shafts link to each other.Material enters the central authorities that aggregate pipe 10 is fallen mill 6 from revolution lock feeding machine 13 by the feed pipe 12 that is installed on the grinding machine shell 11, to border movement, forms the bed of material at the outer rim place on mill 6 surfaces on the surface of action of centrifugal force lower edge mill 6.Be installed on gyroaxis 8 and the grinding roller axle 9 common rocking arms of forming in the column 3 upper shaft bearings, the rocking arm that hydraulic pressure (pneumatic) spring 4 is formed by gyroaxis 8 and grinding roller axle 9 applies grinding pressure to big grinding roller 23 and little grinding roller 22, mill 6 drives grinding roller by the bed of material and does gyration along grinding roller axle 9 separately, and mill and grinding roller roll grinding to the bed of material.Be installed on vane 5 on the toroidal shell 7 and be close to the outer rim of mill 7, have some nozzle bores on the vane 5, the compressed air of heat to bed of material surface winding-up, makes that the fine powder material on the bed of material upwards rises with hot compressed air behind the grinding by the nozzle bore on the vane, forms dusty gas.Dusty gas enters the sound attitude powder concentrator of being made up of grinding machine shell 11, powder concentrator lower house 18, powder concentrator upper shell 19, the guide vane 21 that is positioned at the powder concentrator upper shell and rotor of powder separator 14 successively and selects powder, the particle that granularity is big sinks under the effect of guide vane 21 and rotor 14, enters aggregate pipe 12 by the aggregate bin 18 that is positioned at powder concentrator lower house 17 and falls again and continue grinding on the mill.The fine powder that meets the demands that particle is little is discharged from powder concentrator discharging opening 20 with compressed air, carries out gas solid separation by dust-precipitator, reclaims product.Powder concentrator when work, take reductor 2 16 to by motor 2 15 and make and be installed on the rotor of powder separator 14 that subtracts on the machine output shaft and do gyration, be installed on the guide vane adjustable angle in the powder concentrator upper shell 19.By regulating the angle of compressed-air actuated pressure and guide vane, can obtain varigrained product.
Big grinding roller 23 and little grinding roller 22 are taper and inner small and outside big, and big grinding roller 23 and little grinding roller 22 are installed in pairs at interval.
Roller mill structure of the present utility model: mill 6 surfaces are a plane, processing is simple, simultaneously, mill 6 surfaces particularly grinding zone wear-resisting can adopt card install cheap and complex abrasion-proof steel plate that anti-wear performance is superior as liner plate, mill of the present utility model gets final product as the mill material with spheroidal graphite cast-iron even casting pig.
Grinding roller of the present utility model is the taper grinding roller, is conducive to nipping of lump material, can not go out the phenomenon of the such lump material pressure of phenomenon pot mill roller.
The spaced apart structure of size grinding roller: the spaced apart structure of big or small grinding roller of uniqueness of the present utility model has improved mill efficiency greatly with grinding process refinement more.The utility model separately carries out in small, broken bits, compacting, grinding and the process of grinding process under the prerequisite of conscientiously studying grinding process, and 22 pairs of block bed of materials of little grinding roller carry out in small, broken bits and compacting, and in small, broken bits and material compacting of 23 pairs of big grinding rollers carries out grinding.Traditional vertical roll grinder grinding roller all is big rollers of the same size, that each grinding roller is being born is in small, broken bits, the function of compacting and grinding, because grinding roller roller footpath is bigger, spherical grinding roller rolls when loose lump material, the bigger material piece in upper strata the village can occur and turn over the phenomenon of leaving the grinding zone, grinding roller only carries out in small, broken bits, compacting and grinding to the less material of low layer, so mill efficiency is low.
Practical application proves, the spaced apart innovation structure of big or small grinding roller of the present utility model is under the situation identical at the mill diameter, that grinding roller quantity is identical, than the vertical roll grinder output raising 15-20% of traditional whole big roll structures.
The utility model is combined into a module to hydraulic pressure (pneumatic) spring 4 of passive column 3, the gyroaxis 8 that plays connection power transmission effect, the little grinding roller 22 that plays the grinding effect, big grinding roller 23, a grinding pressurization.Can utilize module combinations of the present utility model to become the vertical roll grinder of different sizes such as 2 rollers, 3 rollers, 4 rollers, 5 rollers, 6 rollers, different output as required, realize modularized design, manufacturing, and install simple.
Utilize the vertical roll grinder of module combinations of the present utility model, when maximizing, only need increase the diameter of mill 6, and increase module, do not need to increase the grinding roller diameter, also do not need to increase height and the intensity of mill platform.Increase output than traditional vertical roller mill by amplifying the grinding roller diameter like this, the increase of grinding machine weight is much smaller, therefore can save wide variety of materials and manufacturing expense.Simultaneously, modular design, manufacturing technology can make cost significantly reduce, and also can make to install to simplify.
