Roll crusher selection example
The roller crusher is suitable for the crushing of brittle materials below medium hardness such as sinter, coal , coke , shale, etc. due to its simple structure, reliable operation, low cost, especially excessive pulverization, but due to its low processing capacity, generally It is only used for medium and small crushing operations in small and medium-sized factories and mines.
At present, China mainly produces double-light rolls, double-tooth rolls, four-beam rolls and four-tooth roll crushers, with a total of only 10 specifications.
Model representation: double (four) light roller is represented as 2 (4) PG or 2 (4) PGG, double (four) tooth roller is expressed as 2 (4) PGC; specifications are generally used roller diameter × length (mm × mm) Indicated, or expressed by the diameter of the roller (mm). Comparison of specifications, specific model specifications are expressed in heavy weight, such as roller diameter 1200mm, length 1000mm, hydraulic adjustment (spring adjustment) coal (sinter) dual-roller crusher expressed as 2PGG-M (S) Y(T)1210, which is not indicated for coal (M) or sintered ore (S), is universal.
The following describes the roller crushers produced by major domestic manufacturers.
