Abstract

Disclosed is a vertical counter-striking roller-swinging suspension mill for breaking and milling medium hard materials. A motor drives a rotor fixed on a main shaft to strike and counter strike the materials, and the materials which drop onto a pressing strip after striking and contrary striking at high frequency form a stacked cushion layer. The materials flow and abrade with each other as the stack of the materials is added. Finer materials and smoother materials are stricken and counter stricken again after dropping and then are milled again, sliding into a guide conic plate and the roller-swinging suspension mill to be extruded, cut and milled. With simple structure and low metal consumption, the utility model can simplify working processes and crush materials whose water content is greater than 1-1.5%.

Description

Vertical striked-swing roll suspension mill

The utility model relates to a kind of size reduction machinery, a kind of vertical impact of more specifically saying so--and the pendulum roller suspends and grinds, and is applicable to medium-hard material is carried out fragmentation, grinding.

At present, generally adopt operations such as fragmentation, grinding to finish, generally adopt secondary or more multiple stage crushing, milling equipment, water content is surpassed 1～1.5% material, also need set up one drying plant the mechanical crushing of material.The impact breaker that uses is to utilize the beater plate that is fixed on the high speed rotor rotated that the material that enters crusher chamber is hit now, make it obtain certain energy and fly to counterpunch board, and rebounded on the beater plate by counterpunch board, the plate that catches a packet once more hits, circulation several times, after making material reach certain fineness, be discharged from cavity.It is very few that this disintegrating machine makes material overwhelm, strike back number of times in crusher chamber, can not realize under low-power, the slow-speed of revolution situation the material fragmentation, and ultra-fine when broken energy consumption big.

The operation principle of the pendulum roller mill that uses now is: can active rotation abrasive body--pendulum is close to the static housing inwall, material is squeezed betwixt, shears and by grinding, the total capacity usage ratio of this milling equipment is low, and with vibration.

The purpose of this utility model is to have designed a kind of vertical impact in order to overcome above-mentioned the deficiencies in the prior art part--the pendulum roller suspends and grinds, make broken integratedly, and when pulverizing water content and surpass 1～1.5% material, have drying function concurrently with grinding, particle size after cracking is thin, and is low in energy consumption.

The purpose of this utility model can realize in the following manner: a kind of vertical impact--the pendulum roller suspends to grind and includes upper shell and lower shell, the centre fuses both with adpting flange, also be fixed with base on the lower shell, be fixed with loam cake on the upper shell, the main shaft two ends be placed in respectively base and on cover, the top of main shaft is equipped with rotor on the position corresponding with upper shell, be fixed with beater plate on the rotor, be fixed with press strip and counterpunch board on the inboard of upper shell, inboard at adpting flange is fixed with burden-guiding cone, on the main shaft of rotor downside pendulum hookup is installed, large end face at adpting flange is fixed with the buoyancy tank adjusting device, it is hanging the buoyancy tank supporting arrangement with chain down, floating box device is installed on the buoyancy tank supporting arrangement, inboard, middle part at lower shell is fixed with the air intake guide plate, blast pipe is fixed on the lower shell bottom, discharge pipe is fixed on and covers, on cover and also be fixed with feed hopper, discharge bucket is fixed on the downside of base, and motor drives main axis rotation by V belt and the belt pulley that is fixed on the main shaft.

The utlity model has following advantage, make broken and grinding integrated, and have oven dry concurrently above 1～1.5% material for water content.This apparatus structure is simple, and efficient height, working service are very convenient, is difficult for sizing during grinding, is a kind of desirable breaker.
