Monga zida zazikulu zopangira phula, malo osakaniza a asphalt adzagwiritsidwa ntchito pama projekiti ambiri omanga uinjiniya. Ngakhale pakhala kusintha kochuluka kwa magwiridwe antchito ndi mtundu wa zida, vuto lake loyipitsidwa likadali lalikulu kwambiri. Mwachiwonekere, izi sizikugwirizana ndi chitetezo chathu cha chilengedwe ndi zofunikira zopulumutsa mphamvu. Ndikudabwa ngati pali chomera chapadera chosakanikirana ndi phula la phula?

Zachidziwikire, ngakhale mtengo wamitengo yosakanikirana ndi phula losakanikira zachilengedwe udzakhala wapamwamba chifukwa cha masanjidwe ambiri, amakondedwabe ndi makasitomala chifukwa amazindikira kuti makina opanga uinjiniya akupanganso njira yopulumutsira mphamvu komanso kuteteza chilengedwe. Choyamba, tiyeni tione kamangidwe ka zipangizo zoteteza chilengedwe. Kuvuta kwake ndi chifukwa cha kuchuluka kwa zigawo zikuluzikulu, kuphatikizapo batching makina, chosakanizira, silo, screw conveyor mpope, masekeli dongosolo, pakompyuta ulamuliro dongosolo, magetsi, control room, fumbi wotolera, etc.
Zigawozi zimaphatikizidwa kukhala dongosolo losindikizidwa bwino, lomwe lingachepetse kuipitsidwa kwa fumbi ndi kutulutsa phokoso. Dongosolo latsopanoli lingathe kuonetsetsa kuti phulalo likusakanikirana mofanana, zomwe mwachibadwa zimakhala zothandiza kuti zigwiritsidwe ntchito.
