The rock is then crushed into smaller pieces and sent to the homogeniser, which allows for any variances in the gypsum size to be reduced, ensuring consistency in each bag of plaster. Calcination makes for perfect plaster . The rock from the homogeniser is ground down even further before it goes through what’s called the calcination process. Here, any water from the rock is removed in a low temperatureОнлайн-запрос
