Description

Composite channel pendulum-type grinding machine and superfine powder system of processing thereof
(1) technical field:
The utility model relates to the breeze disintegrating apparatus, is a kind of composite channel pendulum-type grinding machine and the superfine powder system of processing of using this grinding machine thereof specifically.
(2) background technology:
China is used for the equipment of breeze ultra-fine grinding traditionally, and what comparatively popularize is airflow milling, ring-roller mill, ring roller mill and impact grinding machine, and wherein the airflow milling energy consumption is high; Impact that grinding machine and ring roller mill impact element are wear-resisting to require high factor affecting, on range of application, be restricted, and ring-roller mill is to use thick bed pulverization principle; Adopt and to rub, to shear, roll and carry out the powder fragmentation; Have the crush efficiency height, characteristics such as the crushing energy utilization rate is big, application is expanded year by year.
It is the pendulum type ring roll pulverizer of various models that said ring-roller mill is used the widest representative; Its Cracking Mechanism is that the breeze material is rolled into powder by relatively rotating between grinding roller and the bull ring; Traditional pendulum type ring roll pulverizer is restricted by factors such as its structure and grinding system configuration, and the particle size range of processing is in 0.125~0.044 millimeter.
Tradition pendulum-type scratch system main frame mainly is made up of structures such as base, center pedestal, bull ring, plum blossom frame assembly, grinding roller assembly, central shaft, relieving tool post, shovel seat assembly, steam return box, cover tubes.The workpiece bull ring, grinding roller that roll abrasive dust adopt high-abrasive material to form through casting, and the contact-making surface of itself and material all passes through Wear-resistant Treatment.Treat the particle of the material of grinding through crusher in crushing one-tenth<20mm, deliver to storage bin hopper through elevator, material particles is transported in the main frame chamber through cover tube feeding mouth from storage bin hopper through the belt feeder or the vibrations batcher of adjustable speed.Under the driving of transmission device; Central shaft is driving plum blossom frame assembly, grinding roller assembly, relieving tool post, shovel seat assembly and is rotating together; The grinding roller assembly is installed on the balance staff; Rotation produces huge centrifugal force is close together grinding roller and bull ring, and material is constantly delivered to the material shovel between bull ring and grinding roller under the effect of shovel seat assembly; Bull ring and the grinding roller linear velocity with 8 meter per seconds in relative rotary motion constantly rolls, pushes and shear material under action of centrifugal force, and material is carried out dispersion and fining.Powder after the pulverizing rises to stepped zone under the drive of air-flow; Carrying out the gas grain by turbine classifier separates; Collected by rotoclone collector or pulsating collection device through the powder inlet pipe road through the isolated qualified powder of turbine classifier, main frame falls back in underproof powder, and is rolled fragmentation once more; Classification is collected once more, until qualified.
The broken degree of powder depends on the energy that acts on the powder; The broken energy of pendulum type ring roll pulverizer is mainly derived from the centrifugal force that its grinding roller system rotation produces; And traditional pendulum type ring roll pulverizer is because of its structural limitations, and the centrifugal force of its working speed and generation is not high, and causing grinding pressure, not enough (updating apparatus of pendulum type ring roll pulverizer is a pitch formula flour mill; Burnisher apparatus laterally throws away when rolling; Compare with traditional pendulum type ring roll pulverizer, it is nearly 35% that the centrifugal force of Burnisher apparatus increases, thereby aggravated the broken energy of rolling of powder); Simultaneously pendulum type ring roll pulverizer (comprising pitch formula flour mill) main frame internal gas flow speed is higher, causes more defective fine powder to be in suspended state in main frame inside, influence powder repeat roll.
Traditional pendulum type ring roll pulverizer adds man-hour carrying out fine powder, because the minimizing of inlet amount, the attenuation of the main frame bed of material causes rolling layers too thin, makes that the equipment vibrations are big, and then very easily causes the fatigue damage of other parts, increases maintenance cost, influences the service life of equipment.
Have, the hierarchy system of traditional pendulum type ring roll pulverizer is too coarse again, and effectiveness of classification and classification efficiency are on the low side, is difficult to carry out the superfine powder classification.
For various reasons, above-mentioned traditional pendulum type ring roll pulverizer equipment can't satisfy the production requirement of high order fineness, high efficiency powder body material, therefore is necessary to design and make the higher breeze disintegrating apparatus of mechanical efficiency, to meet the needs of production.
