If the raw limestone is bigger than the input size of your grinding mill, it should be crushed firstly.

The proposed limestone crusher is Impact Crusher, it can crush the material from 1m to –25 mm size.

The crushed limestone will be sent by a belt conveyor to vibrating screen becoming final products or to grinding mill to fine grind.

If the raw limestone is small enough and can be directly grinded by grinding mill, it can be grinded directly.
