Description
Technical field
The utility model relates generally to a kind of grinding production technology of building material industry, especially the roller press grinding system of cement grinding production technology mesohigh window screening plant.
Background technology
Mainly there are following two kinds of forms in the cement grinding process of China: the Joint grinding system of ball mill joined by ball mill grinding system and roll squeezer.Wherein, the process-technology-evolutions comparatively morning of the whole grinding of ball mill, it has the advantage of the simple small investment of technique, but efficiency low energy consumption is high, belongs to relatively backward technique, is just eliminated fast.The combination grinding recent years development that ball mill joined by roll squeezer is very fast, and mill efficiency is high, energy consumption is low feature that it has, become the prevailing technology of Chinese cement grinding, the production line overwhelming majority newly-built after 2000 adopts this technique.
Roll squeezer applying high voltage bed of material pulverization principle, brittle material reduces rapidly through high-pressure extrusion granularity, and has a large amount of micro-crack in all materials through extruding, and improves the grindability of material, make material in next operation during grinding, required energy consumption significantly reduces.Use the extruding grinding system of the pre-grinding of roll squeezer can increase production 50 ~ 200% than former traditional pure ball mill grinding system, per unit area yield power consumption can reduce by 20 ~ 40%, has saved the energy, has reduced manufacture of cement electricity consumption, thus realized sustainable development.
Along with the requirement that country is higher to energy-saving and cost-reducing proposition, how to improve roll squeezer mill efficiency further, the energy consumption reducing grinding system becomes the hot subject of research.
Utility model content
The purpose of this utility model is to provide a kind of roller press grinding system of high efficient, high pressure band screening plant, the winnowing type hierarchical approaches discarded tradition is used mechanical type sieve classification instead and is reduced system energy consumption, fine powder output is increased by roll squeezer high pressure operation, material control realization ball mill is leaked to the adaptability of material after mechanical grading by roll squeezer edge, can system throughput be increased on the whole, reduce system energy consumption.
The technical solution of the utility model is as follows:
The roller press grinding system of high efficient, high pressure band screening plant, comprise roll squeezer and ball mill, weighing cabin is provided with above roll squeezer, the hydraulic system pressure of roll squeezer carries out extruding pulverizing to being fed to material, the fine powder that roll squeezer discharging opening is discharged sends into mechanical sifter by elevator, the particle being less than mechanical sifter mesh size is sent to ball mill, finished product is obtained through fine grinding shaping after entering ball mill, the discharging opening of ball mill is connected has dust-precipitator to collect dust, and the particles circulating being greater than mechanical sifter mesh size turns back in weighing cabin.
Described roll squeezer is provided with side abrasionproof stop gauge, and striker plate partly or entirely rides on roll surface, and by regulating the striker plate control roll press edge of abrasionproof stop gauge to leak doses, leaking doses ratio need lower than 5% of roll squeezer throughput.
Described roll squeezer adopts high-pressure state to run, and the operating pressure of its hydraulic system is at least higher by 15% than adopting the system of selection by winnowing classification.
The utility model mechanical sifter is classifying equipoment, and is equipped with the auxiliary equipment such as elevator, dust-precipitator.Pending fragility raw material carries out extruding by roll squeezer and pulverizes, and by mechanical sifter by the material scattering classification after extruding, carries out fine grinding shaping by ball mill.First fresh material is fed to the weighing cabin of roll squeezer, material (comprising the material that systemic circulation returns) in weighing cabin is fed to roll squeezer and carries out extruding pulverizing, roll squeezer takes high-pressure state to run, its hydraulic system pressure is higher by more than 15% than the system of traditional employing selection by winnowing classification, to improve crush efficiency, produce more fine powder.Roll squeezer need adopt the side abrasionproof stop gauge described in patent 201420162621.5 simultaneously, and its striker plate partly or entirely rides on roll surface, leaks material with the edge reducing roll squeezer, makes the material ratio of not fully extruding lower than 5% of roll squeezer throughput.
Material forms material cake after roll squeezer extruding, wherein contain the granule of a large amount of fine powders and discrepitate, send into through elevator that mechanical sifter carries out breaing up, classification, the particle being wherein greater than mesh size returns roll squeezer weighing cabin, enter roll squeezer to extrude again together with fresh supplied materials, be less than the particle feeding ball mill of mesh size.
The material of feeding ball mill be mainly fine powder, without the small powder cake fully broken up and after extruding the granule of discrepitate, therefore, although its entirety is comparatively thick, there is good grindability, material to enter after ball mill through fine grinding shaping, goes out grind materials and is finished product.
The utility model technological process is unique, not only significantly reduces system energy consumption, also can give full play to roll squeezer crush efficiency, really accomplish the effect that Increasing Production and Energy Saving lowers consumption.
