Iimbonakalo:
1. Uluhlu olubanzi lokusetyenziswa, i-sieved sieved size size particle size kunye nokuchaneka okuphezulu kwe-sieving.
2. Ubuninzi beeleya zesikrini bunokumiselwa ngokweemfuno ezahlukeneyo.
3. Ukugcinwa lula kunye namathuba okugcinwa okuphantsi.
4. Ukusebenzisa i-excitors ye-vibration nge-angle ehlengahlengiswayo, isikrini sicocekile;uyilo lwe-multi-layer lungasetyenziswa, imveliso inkulu;uxinzelelo olubi lunokukhutshwa, kwaye okusingqongileyo kulungile.
