Xa i-jaw ruser iyasebenza, i-rava esundul 'ihlasekile iphindaphindwe ngokuchasene neplate ye-daw, ngamanye amaxesha isondela ukuya kwaye ngamanye amaxesha sihambe. Xa esondela, izixhobo zityunyuzwa ngokuqina, zihluma, kwaye zinefuthe phakathi kwemihlathi emibini; Xa ukuhamba, izinto ezityumkileyo zikhutshiwe kwi-port ekhuphayo ngumxhuzulane.
Kwinkqubo yokutyumza amatye amakhulu kumatye amancinci, umngxunya wokuqala uhlala u "brisher" ophambili. Eyona inde kakhulu kwaye inomsindo onamandla ngumhlathi womhlathi. Xa esondla i-jaw crusher, izinto ezibonakalayo zithululelwa kwigumbi lokutyumza elinamazinyo angaphandle, kwaye amazinyo okuhlathi atyhalela umxholo ophambili kwaye aphule kumatye amancinci. Ukuxhasa ukuhamba kwamazinyo okuhlathi ngumthunzi we-eccentric, ongena kwisakhelo se-fussege. Isindululo se-eccentric sihlala siveliswa ziiflowhechels ezilungiselelwe kuzo zombini iziphelo zeshafti. I-Spherical Rolling Bralys zihlala zisetyenziselwa i-flywheel kunye nenkxaso ye-eccentric. Iibheringi kufuneka zikwazi ukuzimela imithwalo enkulu yefuthe, i-abrasive lage kunye namaqondo obushushu aphezulu.
