PGG1200×1000型四輥破碎機 Four  Roll Crusher

4PGG1200×1000型四輥破碎機主要用于破碎冶金焦煤。也可以通過調整上下輥的間隙，破碎粒度較大的物料，其特點是，機器結構緊湊，占地小，破碎比大（18：1）并且產量較高。

4PGG1200×1000 four roll crushers are mainly used to crush  metallurgy coking coal. They can also crush materials of large particle size by  adjusting the gap between the upper roller and lower roller.
