Description
Technical field
This utility model relates to the lifting wall device at the end wall place of a kind of tumbling mill.This utility model further relates to a kind of sections promoting wall device and a kind of tumbling mill including promoting wall device.
Background technology
In rotary drum-type grinding machine, the material of breaking ores form is fed into one end (input end wall) of grinding machine, and the Ore through milling is extracted by material output tap (tap) being centered about at the second end (output end wall) place of grinding machine.In materiel machining, grinder is under crystallite dimension level, by wearing away and the machine of compression stress reduction granularity.Typical refiner is tumbling mill.At period supply water of milling so that the fine ore particles divided and water form slurry (pulp) or mud (slurry).Tumbling mill generally includes shell, this hull shape become between input end wall and output end wall big, be mainly cylindrical compartment.This compartment is commonly called grinding chamber.It is connected with output end wall, promotes wall device and be set to discharge slurry from grinding chamber.Promoting wall device and include multiple pulp lifter, wherein each pulp lifter generally includes: inwall, towards grinding chamber；And relative outer wall, towards output end wall.Pulp lifter is radially arranged about rotation axis, and rotates together with grinding machine.Promote wall device and can include inner radial pulp lifter and radially outer pulp lifter.Multiple limiting walls being radially arranged or carrier are arranged on inwall or outer wall, are evenly distributed around rotation axis.Described carrier limits multiple compartment together with inner and outer wall, and these compartments are referred to as pulp lifter room.Pulp lifter room generally becomes more and more narrow along the direction towards center of rotation, and at center of rotation place, slurry is drawn towards center discharge cone.Discharge cone extends into output tap.The inwall of pulp lifter generally includes screening opening (sievingopening), slurry or mud and enters pulp lifter room through this screening opening.During the rotation of grinding machine, when pulp lifter is positioned in the lower position of rotation, the slurry in grinding chamber is thus directed over screening opening and enters pulp lifter room.When pulp lifter has arrived at the upper position of rotation, slurry falls to discharge cone and therefore drops to output tap.Pulp lifter room thus form multiple discharge-channel, the task of these passages be grinding machine rotate during, be guided out the slurry containing ore deposit from the grinding chamber of grinding machine.As used herein, term " slurry " also includes mud and other material being ground.
The current common issue promoting wall device is the installation of independent assembly and removes.The outer wall of each pulp lifter is generally firstly provided at correct position, and by bolt output end wall from grinding machine internal attachment to grinding machine.Inwall is then act through stay bolt and is attached to outer wall, and this stay bolt extends past inner and outer wall.This program is burdensome and consuming time.Should also be noted that stay bolt is heavier and improper is handled during assembly and disassembly operation by operator.Such as, document WO2011/095692A1 discloses the pulp lifter assembly of a kind of rotary grinder, and wherein grid (grate) is attached to each pulp lifter by securing member.
Document US3799458A discloses a kind of tube mill material lifting wall, it includes two dishes (disc), each dish is made up of single sections, wherein relative sections engages at their outer end place and has lifting blade between their outer end, and this lifting blade is suitable for when it rotates being lifted in cylinder the material of process.Relative sections is attached in couples by connecting web, and this connection web adheres to the shell of tube mill to form the component with U-shaped cross section.Therefore sections is welded to their connection web so that they form rigid element.Web is swirled to tube mill shell.Sections is also engaged regularly by spacer element.This is the structure of a kind of complexity, and this structure can cause promoting the installation of the parts of wall and keeping in repair consuming time and inconvenient.
Although there is the lifting wall device of various structure, but need nonetheless remain for developing a kind of lifting wall device, this lifting wall device reduces the time installing/remove various assembly, and optimizes the weight promoting wall device.
