Dolomite crushing and sand making equipment programme needs to be combined with the process flow, equipment selection and production demand for comprehensive design. The following is the summary of key points:

Dolomite crushing and sand making Core equipment selection

Coarse crushing stage

Jaw Crusher

Jaw Crusher: suitable for primary crushing of large dolomite, with deep V-shaped crushing chamber and high crushing ratio.

Medium Crushing Stage

Impact Crusher

Impact Crusher: Optimise the particle size of the material, suitable for the medium crushing of medium hardness dolomite.

Fine Crushing and Sand Making Stage

Roller Sand Maker

Roller Sand Maker: Precise control of particle size (e.g. 1-5mm) through double-roll extrusion and hydraulic system, suitable for high precision requirements.

Auxiliary Equipment

Vibrating Screen: Grading and screening of aggregates with different particle sizes.
Sand washing machine: improve the cleanliness of the finished products, in line with the requirements of environmental protection.

Process Flow Design

Basic Flow

Raw material → Jaw Crusher coarse crushing → Impact Crusher medium crushing → Roller Sand Making Machine fine crushing → Vibrating Screen → Sand Washing → Finished product storage.

Dolomite Crushing and Sand Making Equipment Selection Key Factors

Output Requirements

50-100 tonnes per hour: roll sand making machine solution is more flexible.

Finished Product Quality Requirements

Construction Aggregate: need to match with sand washing machine to improve the cleanliness.
1-5mm high-precision sand: Roller sand making machine is preferred.
