Description

Annular grinder

The utility model is a kind of improved annular grinder, belongs to multi-layer cylinder shape grinding mill technical field, is particularly useful for the raw material grinding of industries such as mine, metallurgy, chemical industry, building materials, refractory material, production of phosphate fertilizer.

As everyone knows, traditional milling equipments such as the general ball mill in countries in the world, Raymond machine, centrifugal mill, problem such as the ubiquity mill efficiency is low, energy consumption is high, the steel consumption is big.A kind of ring centrifugal grinding mill has appearred in late nineteen eighties, though the advantage of efficient height, energy savings, but exist grinding particle size thick, the defective of replacing consumable accessory inconvenience causes this equipment promotion utilization scope to be very limited, and says nothing of to make it to have maximized.

The purpose of this utility model provides that a kind of properties of powder performace is thinner, efficient is higher, more energy-conservationly easily change consumable accessory again, be easy to safeguard and can be to maximization the annular grinder of super-hugeization development.

Solution of the present utility model is, this improved annular grinder, referring to accompanying drawing, by support (9), the main shaft (10) of vertical axes earthing of frame (9), the stacked Multi-layer rotary top (7) that is coupling on main shaft (10), be sleeved on by pin (6) and grind ring (4.1 on each layer rotating disk (7) periphery, 4.2), liner (5.1,5.2), casing (8), feed hopper (1), discharge nozzle (11) and motor (13) are formed, wherein motor (13) is in transmission connection by driving-belt (12) with main shaft (10), above-mentioned liner (5.1,5.2) respectively and rotating disk (7) with between be separated with a working chamber (3), working chamber (3) top is logical with feed hopper (1) and discharge nozzle (11) pipe successively respectively with the below, improvements are that described casing (8) inner chamber is isolated into the mill chamber and is ground two logical operating rooms of mutual pipe, chamber down by a dividing plate (16) radially with holes, the above-mentioned ring (4.1) that grinds is positioned at the mill chamber, grind ring (4.2) and be positioned at secret room down, have on the casing (8) at least more than one the door chamber and door along on the door (14) of and door chamber size coupling hinged by hinge (15), the described ring (4.1 that grinds, 4.2) respectively by the upper semi-circle step ring body (4.11 that has corresponding step, 4.21) and lower half circle step ring body (4.12,4.22) successively by each self-corresponding on, superimposed being formed by connecting of getting out of a predicament or an embarrassing situation, wherein ring (4.1) axial cross section that grinds that is connected by upper semi-circle step ring body (4.11) and lower half circle step ring body (4.12) is the annulus cylindricality, ring (4.2) axial cross section that grinds that is connected by upper semi-circle step ring body (4.21) and lower half circle step ring body (4.22) is the annulus sphere, and grind outside ring (4.2) upper bottom surface electrical path length less than the outer electrical path length of bottom surface, the above-mentioned ring (4.2) that grinds that is placed on indoor each layer rotating disk (7) on the pin (6) that grinds down is axial two of folding mutually, axial cross section is two of annulus sphere, and to grind ring (4.2) folded mutually with its big outer-diameter ring face correspondence respectively, described liner (5.1,5.2) surface of internal cavity has successively respectively and grind ring (4.1,4.2) coupling mill groove, liner (5.1) groove face that wherein is positioned at the mill chamber is the annulus cylindricality, be positioned at liner (5.2) groove face that grinds the chamber down and be the annulus sphere, and liner (5.1,5.2) be fixed on casing (8) and door (14) surface of internal cavity by the key seat (17) of bolt (19) tape shaped pin hole (18) and the fastener dislocation of nut (20) formation respectively.Adopt door closure open-type housing therefrom,, detachable split liner and combined type grind ring, solve huge and heavy grinding machine and change consumable accessory simplification problem, this machine down mill chamber adopts to have with the liner that grinds the Internal Spherical Surface groove of global coupling and can increase milling area to material, make mill efficiency carry De Genggao, granularity is thinner, and is energy-conservation more.

The operation principle of the design's this improved annular grinder is that this annular grinder is driven by motor (13), transmit moment of torsion by driving-belt (12) and give main shaft (10), main shaft (10) drives rotating disk (7), grind ring (4.1,4.2) together rotation, after material falls to entering working chamber (3) continually by feed hopper (1) simultaneously, material is subjected to the centrifugal action that rotating disk (7) rotation gives and is close to working chamber (3) outer wall and freely falls, grind ring (4.1 simultaneously, 4.2) drive when making circular motion (revolution) owing to powerful centrifugal action is pressed to working chamber (3) outer wall by rotating disk (7), therefore the material in the working chamber (3) is ground ring (4.1,4.2) impact, roll, and pulverized layer by layer, the material after the pulverizing is released by discharge nozzle (11).Because as having at least more than one door (14) on the above-mentioned casing (8), and liner (5.1,5.2) be that a plurality of and casing (8) or door (14) inner cavity surface of split is connected the pad of dying and having excellent sealing and adjustability by the dislocation of bolt and bar shaped pin hole, grind ring (4.1,4.2) also be to be connected with the superimposed bolt of lower half circle step ring body by knock-down upper semi-circle step ring body, so can in casing (8) housing, dismantle the block liner (5.1 of wearing and tearing by opening door (14) by removing bolt, 5.2) and combination grind ring (4.1,4.2), change new liner again and grind ring, totally unnecessary picture is traditional slings and dismantles the replacing that whole grinding mill body is realized consumable accessory, thereby simplified the part replacement program widely, saved energy consumption, improved operating efficiency, alleviate maintenance difficulty, and created condition for the maximization of grinding mill and super-hugeization.
