Description
(1) technical field:
The present invention relates to powder process equipment, is a kind of oblique pendulum waterfall material flour mill specifically.
(2) background technology:
Flour mill is breeze sector application equipment the most widely, and wherein the most representative equipment is raymond mill.
The universal architecture of raymond grinding powder machine host is: hollow central shaft bracket and coaxial bull ring and cover cylinder are housed on main machine base, main frame main shaft is located in central shaft bracket, fixed roll frame (or claiming plum blossom frame) is equipped with in the main frame main shaft upper end of stretching outside central shaft bracket, on fixed roll frame, by the even hanging of hinge device, there are a plurality of and central axes and are the grinding roller assembly of circle distribution, grinding roller assembly is comprised of grinding roller sleeve and grinding roller, in the revolution process of grinding roller assembly, grinding roller assembly makes to keep rolling between each grinding roller and bull ring to contact by centrifugal action, mutually rolling between grinding roller and bull ring reaches crushing material the object of producing powder, this is the Cracking Mechanism place of abrasive dust main frame.
The charging aperture of raymond mill is opened on cover cylinder, the material entering from charging aperture is directly to fall in main machine base bottom from bull ring substantially, it is mainly rely on relieving tool post to drive perching knife rotation and complete that material rolls between grinding roller and bull ring, and described perching knife throws material between the corresponding grinding roller and bull ring arranging.
Because perching knife material casting angle is certain, and material is from fine sand to 4 centimetre piece not etc., light, heavy material movement locus is different, and quite a few aniseed is idle to fly away, and causes feeding not enough, is that raymond mill yield in unit time is not high, the major reason of inefficiency.
(3) summary of the invention:
For this reason, the present invention proposes a kind of oblique pendulum waterfall material flour mill, mainly solve the low problem of traditional raymond mill working (machining) efficiency.

In said structure, material is piled up prior to buildup district, along with material is cumulative and work in the vibrations of abrasive dust main frame, material can be along the landing as the waterfall of taper flour milling, the self-assembling formation between district of milling at grinding roller and bull ring is milled material bed, be accompanied by the continuous feed of perching knife and force to form and mill material bed (perching knife is thrown the material flying and fallen buildup district), the mill increase of district's inventory and material bed thickening, established solid foundation for improving output and efficiency; And taper flour milling has increased the area of milling, the weight fraction masterpiece of grinding roller has increased on bull ring the power of milling, and output and efficiency are further enhanced.
The length of grinding roller sleeve can be made as identically, described grinding roller tiltedly hangs height and becomes individual layer roller in same; Or the length of described grinding roller sleeve is made as difference, grinding roller tiltedly hangs height and becomes two-layer with top roll (comprising two-layer roller) in different.
Conventionally grinding roller sleeve be made as to two kinds of length and form the two-layer roller of upper and lower dislocation.
For further improving the power of milling, between described grinding roller sleeve and relieving tool post, be provided with the thrust mechanism that grinding roller sleeve is produced to thrust, the active force of described thrust mechanism is axial perpendicular to grinding roller sleeve.
Described thrust mechanism is elastic body or is hydraulic mechanism, Huo Wei air pressure mechanism, or be the combining structure of elastic body and hydraulic mechanism or be the combining structure of elastic body and air pressure mechanism.
For making the returning charge after classification be gathered in buildup district, in described cover cylinder, coaxial inner core is set, between cover cylinder and inner core, form the ring cavity of charging and classification returning charge, the graded region corresponding to cover cylinder suitable for reading of described ring cavity, the end opening of described ring cavity is corresponding to buildup district.
Beneficial effect of the present invention:
1, the present invention tiltedly puts waterfall material flour mill buildup district employing waterfall cutting mode is set, and forms two materials of milling of supplying with in conjunction with perching knife feed, realizes the even feed to the district that mills.
2, the present invention, due to even feed, has eliminated the unnecessary consume of empty mill mutually between grinding roller and bull ring.
3,, in the present invention, when grinding roller quality, the radius of gyration, outstanding high, speed of gyration are constant, the grinding roller leaning to can additionally increase the power of milling of material, leans to the angle power of greatly milling and increases; Material extends through taper grinding face drop-out time simultaneously, is conducive to mill.
4, the present invention is owing to there being the effect of milling of nature reinforcement, more favourable to the material that Mohs' hardness is high.
5, the present invention is simple in structure, cost is low, manufacture handling ease, is the preferred unit of flour mill of new generation.
