W przypadku mizdry garbarskiej o frakcji równej 15 mm i mniejszej niż 15 mm i podwyższonej wilgotności, zastosowano domieszki suche. Po rozdziale frakcji mizdry garbarskiej na wytrząsarce sitowej (1) dodaje się mizdrę ze zbiornika mizdry (2) oraz z rozdrabniacza (6) słomy rozdrobnioną słomę do kosza wsadowego (3), a w tulei (5) grzewczej ślimaka tłoczącego następuje brykietowanie mizdry. W przypadku mizdry większej niż 15 mm zastosowano suszenie konwekcyjne, po przesianiu na wytrząsarce (1) sitowej i rozdziale frakcji mizdry następuje suszenie konwekcyjne, a następnie dodaje się z dozownika dodatków płynnych w postaci oleju do mizdry. W tulei (5) grzewczej ślimaka tłoczącego następuje brykietowanie mizdry. Tuleja grzewcza ma każdorazowo temperaturę od 105°C do 220°C. Sposób brykietowania prowadzony jest każdorazowo w temperaturze otoczenia w granicach od +5°C do +30°C.
