Coal crushing from 50 mm to 5 mm

DVZ crushers are roller-toothed crushers for primary crushing of slag with a maximum input material size of up to 25-60 mm. DVR crushers are equipped with smooth or grooved rollers for crushing final product of up to 5 mm in size. They can also be used for economical crushing of coal, burnt lime, artificial fertilizers, and de-icing salts

    Feb 02, 2019 In the preparation of the samples, the waste rocks needed to be crushed to 30 mm down: manual hammer-crushing produced a 50 mm down grading before crushing to 30 mm down. Thereafter, square aperture screens (5 mm, 10 mm, 15 mm, 20 mm, 25 mm, and 30 mm) were used to grade samples (Fig. 2). For the crushed waste rocks, each group of samples was
