Kev sib hloov ceev npaum li cas rotary koov-breaker tshuab cuam tshuam rau kev ua kom tawg?
Kev sib hloov ceev ntawm lub teb chaws chan-breaker tshuab yog nonlinarly ntsig txog kev ua txhaum-kev ua txhaum cai. Muaj ib qho tseem ceeb ntawm qhov tseem ceeb thiab kev ua tau zoo tshaj plaws, uas yuav tsum tau tswj kom ncaj raws li cov khoom siv khoom.
Thaum lub nrawm nrawm (feem ntau<15rpm), the shear force and impact force generated by the cutter are insufficient, and the material can only be slightly displaced by surface friction, which makes it difficult to break the cohesion and adhesion of the material. For example, when dealing with cement lumps with a repose angle of 45°, the arch breaking time is as long as 25 minutes at a speed of 10rpm, which can only loosen the surface material, and the deep arch structure remains intact.
Thaum lub nrawm yog nce rau qhov tseem ceeb tshaj plaws ({15-30 rpm), τsh rpm (τ) Nyob rau lub sijhawm no, lub zog centrifugal tsim los ntawm kev sib hloov cuam cov khoom rau lub phab ntsa silo, rhuav tshem adhesion koov; Cov neeg sib txuam sib txuas mus txuas ntxiv mus rau shear thiab tsoo lub agglomerates rau hauv cov dej ntws. Kev ntsuas ntsuas tiag tiag tau qhia tau tias ntawm kev nrawm ntawm 25RPM, kev ua cov hmoov nplej ua kom muaj zog ntawm 15RPM, thiab lub sijhawm ua tau ua tiav rau 6 feeb.
However, too high a speed (>35RPM) yuav ua rau poob peev txheej. Kev kub ceev ua rau muaj kev tawg rog muaj zog, uas ua rau muaj kev sib txhuam thiab cov cua, ua rau saum npoo ntawm cov khoom nplaum kom tawv. Nyob rau tib lub sijhawm, cov kev co lub zog ntawm cov khoom siv ntau tshaj qhov txwv, thiab cov kev sib tw cenindal ntau dua cov kabmob thauj khoom tsawg dua, ua rau cov cuab yeej tsis txaus ntseeg thiab kev hnav tsis meej. Piv txwv li, thaum ua cov kua qab zib, txawm hais tias qhov ceev ntawm 40RPM nce ceev ceev ceev hauv lub sijhawm luv luv, kev ua haujlwm ua haujlwm los ntawm 30% tom qab 30 feeb vim yog adhesion thiab tawv tawv.
Cov khoom txawv txawv cov yam ntxwv txiav txim siab qhov kev ceev ceev: Cov ntaub ntawv viscosity high-viscosity yuav tsum tau qis dua rau kev txiav txim siab lub sijhawm; Cov ntaub ntawv plua plav yuav tsum tau tswj cov kab nrawm (tsawg dua lossis sib npaug nrog 5m \/ s) kom tsis txhob muaj hmoov av diffusion. Qhov nrawm tuaj yeem sib phim los ntawm cov kev cai ceev sib txawv los ntawm kev ua kom zoo dua ntawm kev ua kom zoo los ntawm 30%}}
