How to select a crusher for granite sand making?When using granite to make sand, the first consideration should be the high hardness, high wear resistance, and high compressive strength of granite. This will affect the selection of granite sand making equipment, and it is necessary to consider crushers with strong wear resistance.
Usually requires multi-stage crushing, coarse crushing, medium crushing, and sand making. Jaw crushers are commonly used for coarse crushing, cone crushers may be used for medium crushing, and roller crushers are used for sand making
Recommended combination of granite sand core crushing equipment
1. Granite sand making Rough crushing stage
Selection: Jaw crusher
reason:
Processing 800-1500mm large raw materials with a compressive strength of 320MPa
Hydraulic adjustment discharge port (150-350mm), crushing ratio 5-8
2. Granite sand making Intermediate crushing stage
Selection: Cone Crusher
reason:
Principle of laminated crushing, granite finished product needle shaped ≤ 10%
Intelligent hydraulic system overload protection, sealed dust-proof structure extends bearing life
3.Granite sand making Sand making stage
Selection: Roll sand making machine
reason:
Mainly using extrusion crushing, with high energy utilization rate, suitable for large-scale production.
By adjusting the roller spacing, the discharge size can be flexibly controlled to reduce over crushing and achieve high particle uniformity
