Basing the use on the cement product line, the roll squeezer has some main merits:

1 Improves output: The roll squeezer in grinding system transforms the high pressure to material layer by its two rollers. The huge power is used to press, grind, tear the raw material so that it improves the grinding mills’ potential capacity by 50% to 100% and saves 20% to 30% energy. The productivity of whole system is improved by so.

Saving electricity energy: The granularity of raw material would be decreased sharply and the band work index also decreases observably, after squeezed by roll squeezer. So, the milling efficiency is improved and the energy of the whole system would be saved add the saved lot. Comparing with traditional process, it may save 25% to 50% of energy and the annual economic earning is substantial.

Save investment: Comparing with the tube mill at the same output capacity, the roll squeezer is simple, small, light and cheap in civil engineering cost. It is also easy to be added into the original grinding system. Besides, its operation and maintenance are also easy.

Improvement in work environment: The raw material is squeezing in the shell so that the fly ash is not suffused easily. At the same time, there is almost no crush so that the noise is lighter than tube mill.

Big size: Because of the conditions of machinery, transport and thermal treatment, the upsizing of tube mill is limited. However, the squeezer system solved these problems and the upsizing is realizable.
