Abstract
A vertical spiral agitator ore mill includes a cylindrical drum having a rotatable spiral agitator mounted therein and a coarse separator mounted on an agitator shaft. The spiral stirrer adopts an assembly structure, the material is cast by wear-resistant cast iron through a special process, and the lower end of the spiral stirrer is an inverted cone. The equipment can be used for fine grinding or superfine grinding of materials in industries such as metal, nonmetal, chemical industry, building materials, light industry and the like. It has the advantages of easy start, strong levigating ability, low steel power consumption, small vibration, low noise, small floor area, simple equipment structure, low capital investment, etc.
Description
The utility model is to be applied to the fine grinding of material in the industries such as metal, nonmetal, chemical industry, building materials and light industry or the vertical spiral agitating mill of ultra-fine mill.
The existing vertical agitating mill that is used for material fine grinding or ultra-fine mill is owing to adopt the integral solder spiral on the structure, spiral lower end is a disc, and the subject matter of existence is: the spiral agitator wearing and tearing are big, the starting under load difficulty.For the dry-type spiral agitating mill, it is big also to exist the loss of grinding machine inner high voltage, needs to increase the power of blower fan, shortcomings such as supplementary classification system complex.(seeing United States Patent (USP) 4660776, China's " comminution engineering " 1988 1 phases).
The purpose of this utility model provides a kind of spiral agitator long service life, can starting under load installs, easy to operate vertical spiral agitating mill.
For achieving the above object, main technical schemes of the present utility model is: the spiral agitator of vertical hanging is to be assembled into one by a plurality of helical blades and shaft in cylindrical tube.Helical blade forms through the special process casting with wear resistant cast iron, upper and lower can the exchange, thereby prolong service life more than 10 times.The spiral agitator lower end is a cone, and having solved in the past, the lower end is that disc card ball causes the startup difficulty.On shaft top a width of cloth is installed and is penetrated the foliaceous coarse separator, rotate synchronously with shaft, thereby can obtain fine product, make compact conformation through one section open-circuit grinding.In order to reduce the loss of grinding machine inner high voltage, keep certain air velocity in the grinding machine, at the cylindrical shell middle part waist air port is set, reduced the power of blower fan.
Accompanying drawing is the utility model structural representation.
The drawing label is: 1---motor; 2---cycloidal planetary gear speed reducer; 3---bearing block; 4---coarse separator; 5---shell liner; 6---cylindrical shell; 7---spiral agitator; 8---supporting leg; 9---under casing; 10---the reductor bearing; 11---air outlet; 12---the waist air port; 13---feed port; 14---products export.
Description of drawings:
One, standing part: cylindrical tube (6) is divided into three joints, be installed on three supporting legs (8) with Bolt Connection, cylindrical shell (6) upper end installation shaft bearing (3) and reductor bearing (10) are used for supporting agitator (7), reductor (2) and motor (1).Cylindrical shell (6) cylindrical has air outlet (11), waist air port (12), feed port (13), products export (14).Abrasion-proof backing block (5) is housed in the cylindrical shell (6), and under casing (9) is equipped with in its lower end.
Two, motion parts: spiral agitator (7) is by telegraph key helical mixing blade to be assembled on the axle of agitator, is hung vertically in the cylindrical shell (6).Motor (1), cycloidal planetary gear speed reducer (2), coarse separator (4) and spiral agitator (7) are formed one, spiral agitator (7) rotation under motor (1) drives.
Major advantage of the present utility model is: can starting under load freely, levigate ability is strong, steel power consumption consumption is low, vibrate for a short time, noise is low, floor space is little, simple in equipment, capital expenditure are less etc.
Use step of the present utility model is: motor (1) rotates by the spiral agitator (7) that cycloidal planetary gear speed reducer (2) drives on the helical axis.Be full of certain steel ball b in the cylindrical tube (6), steel ball b makes complicated multi-dimensional movement in cylindrical shell.Material feeds from feed port a, material between the steel ball, between steel ball and the spiral, ground between steel ball and the barrel and pulverized.Air by air blast by be installed in the cylindrical shell, the waist airduct (12) and the end airduct of bottom blast grinding machine, rise in machine with the material gas mixture of mixing of materials, coarse granule falls back to regrinding through penetrating foliaceous coarse separator (4) detention with the width of cloth of the synchronous rotation of spiral agitator (7).Levigate material is discharged from grinding machine products export d through coarse separator.
This machine is used for certain calcium carbonate factory powdered whiting fine grinding, 3～0 millimeters of feed preparation unit sizes, product granularity-325 order accounts for more than 80%, device start freely, spiral weares and teares very little through 700 hours running backs.
