Abstract
The utility model relates to a dry ball grinding mill which is composed of a motor (1), a speed reducer (2), a pinion gear (3), a bull gear (4), a machine seat (7) and a tube body (10). The dry ball grinding mill is characterized in that both ends of the tube body (10) are fixed and connected with a feeding tube (11) via an end cover (12), a 300 mm to 600 mm grid cavity (15) is formed through grid plates (14) at the middle position of the tube body (10), a tube body rotating screen (5) is fixed on the periphery of the grid cavity (15), and a feeding opening (16) is connected with the lower end of the tube body rotating screen (5), therefore, the ore grinding fineness can reach the effect of a wet ball grinding mill, the grading is simple, convenient and easy, the production efficiency is high, and the dry ball grinding mill is especially suitable in areas lacking water resources.
Description
Technical field:
The utility model relates to a kind of ball mill, particularly a kind of dry ball.
Background technology:
Ball mill has the branch of dry type and wet type, generally is used for metals such as gold, silver, copper, iron, plumbous zinc, and in the grinding flowsheet of nonmetallic ore such as fluorite, potassic feldspar.Along with the enhancing day by day of scarcity and people's environmental consciousness of water resource, the advantage of dry ball highlights gradually, not only saves water resource, and does not have sewage discharge.The dry ball ends that adopt enter the ore deposit more at present, and an end ore discharge is established 2----3 chamber and carried out stage grinding in the cylindrical shell, and production capacity Xiao ， Mo ore particle degree is big, and the rate of recovery is low.
Summary of the invention:
The purpose of this utility model will provide a kind of mog to reach the wet ball mill effect exactly, and classification is easy easily, and the production efficiency height is applicable to the dry ball of dry dirty environment.
The purpose of this utility model is achieved in that a kind of dry ball, form by motor (1), reductor (2), pinion (3), gear wheel (4), support (7) and cylindrical shell (10), it is characterized in that described cylindrical shell (10) two ends are by the fixedly connected feed pipe of end cap (12) (11), cylindrical shell (10) centre position forms the grid chamber (15) of 300-600MM by grate (14), the peripheral fixedly connected cylindrical shell in grid chamber (15) changes sieve (5), and cylindrical shell changes sieve (5) lower end and connects discharging opening (16).
An optimum implementation of the present utility model is: there is screw thread feed pipe (11) inside, and cylindrical shell changes sieve (5) and is fixedly connected on the cylindrical shell (10), and there is fixing seal cover (13) outside, and end cap (12) is connected on the support (7) by bearing block (6).
The utility model compared with prior art has the following advantages: owing to adopted cylindrical shell (10) two ends by the fixedly connected feed pipe of end cap (12) (11), cylindrical shell (10) centre position forms the grid chamber (15) of 300-600MM by grate (14), the peripheral fixedly connected cylindrical shell in grid chamber (15) changes sieve (5), cylindrical shell changes the version that sieve (5) lower end connects discharging opening (16), thereby, mog reaches the wet ball mill effect, classification is easy easily, the production efficiency height is applicable to dry dirty environment.
Description of drawings:
Fig. 1: be the structural representation of the utility model " two endfeeds "
Fig. 2: be concrete structure schematic diagram of the present utility model
Fig. 3: be the structural representation of the utility model " cylindrical shell changes sieve "
1, motor 2, reductor 3, pinion 4, gear wheel 5, cylindrical shell change sieve 6, bearing block 7, support 8, high speed shaft coupling 9, low-speed shaft coupler 10, cylindrical shell 11, feed pipe 12, end cap 13, fixing seal cover 14, grate 15, grid chamber 16, discharging opening
The specific embodiment:
Motor (1) is connected with reductor (2) by high speed shaft coupling (8), reductor (2) is connected with pinion (3) by low-speed shaft coupler (9), pinion (3) and gear wheel (4) engagement, gear wheel (4) is connected on the cylindrical shell (10) with bolting, cylindrical shell (10) two ends are by the fixedly connected feed pipe of end cap (12) (11), cylindrical shell (10) centre position forms the grid chamber (15) of 300-600MM by grate (14), the peripheral fixedly connected cylindrical shell in grid chamber (15) changes sieve (5), cylindrical shell changes sieve (5) lower end and connects discharging opening (16), cylindrical shell changes sieve (5) and is fixedly connected on the cylindrical shell (10), there is fixing seal cover (13) outside, and end cap (12) is connected on the support (7) by bearing block (6).
During use, material enters feed pipe (11) by the charging aperture at two ends, the inboard manufacturing of feed pipe (11) has screw thread, screw thread promotes material and enters in the cylindrical shell (10), cylindrical shell is equipped with a certain amount of steel ball in (10), cylindrical shell (10) is pressed certain speed and is rotated, material is ground, levigate material changes sieve (5) discharge through being positioned at the middle cylindrical shell of cylindrical shell (10), because cylindrical shell (10) quick rotation, the bulk materials on sieve nest top is not necessarily discharged immediately, can can constantly shake simultaneously with cylindrical shell (10) revolution, knock sieve nest and make it to be difficult for stopping up, thin material falls into the fines conveyer belt and transports after the sieve nest screening, coarse fodder is returned through chute inflow coarse fodder conveyer belt by sieve nest top and regrinds.
Claims (4)
1, a kind of dry ball, form by motor (1), reductor (2), pinion (3), gear wheel (4), support (7) and cylindrical shell (10), it is characterized in that described cylindrical shell (10) two ends are by the fixedly connected feed pipe of end cap (12) (11), cylindrical shell (10) centre position forms the grid chamber (15) of 300-600MM by grate (14), the peripheral fixedly connected cylindrical shell in grid chamber (15) changes sieve (5), and cylindrical shell changes sieve (5) lower end and connects discharging opening (16).
2, a kind of dry ball according to claim 1 is characterized in that there is screw thread described feed pipe (11) inside.
3, according to claim 1 dry ball, it is characterized in that described cylindrical shell changes sieve (5) and is fixedly connected on the cylindrical shell (10), there is fixing seal cover (13) outside.
