<p>The plant, operated by a card control system, consists of a central frame with dispensers (R1, R2) for gravel, sand and cement from three separate storage zones (Z2, Z3, Z4), and a mixer (M) with an output system which sends the mixed materials to different zones (T1, T2, T3) for bulk loading, packaging in sacks or supple 'big bag' containers. A water tank adjacent to the mixer supplies water to it as required.</p> |
