Limestone is important buiding materials, and raw materials for cement production. We must crush limestone into suitable size through crushing process in limestone processing plant.
Limestone crushing and screening system usually include jaw crusher, cone crusher, impact crusher, vibrating screen, mobile crusher etc. These machines are used to crush limestones into smaller particles. According to the different products, we choose the different crushing process. Usually limestone crushing and screening plant includes primary crushing process and secondary crushing process. For the Limestone crushing and screening production lines: 30-50tph, 50-80tph, 80-120tph, 120-200tph, 200-300tph, 300-400tph, and 400-500tph, we here recommend three proposals:
- vibrating feeder + primary Jaw crusher + impact crusher + Vibrating screen + belt conveying system + control system
- vibrating feeder + primary Jaw crusher + fineness Jaw crusher + impact crusher (optional) + vibrating screen + belt conveying system + control system
- vibrating feeder +primary Jaw crusher + cone crusher + impact crusher (optional) + vibrating screen +belt conveying system + control system
In the above proposals, the main difference is the secondary crusher: using impact crusher (hammer crushing principle), or using fineness Jaw crusher (plate pressing principle), or Compound cone crusher (plate pressing principle).
Spodumene: According to the hard rock crushing process, the crushed product is generally 5-40mm, combined with different design requirements of customers, two-end or three-stage crushing, high-grade crushed products (above 4-5%) can be directly used in the metallurgical process to produce lithium carbonate Or lithium hydroxide, the particle size of the finished product is generally around 20-40mm; low-grade generally requires ball mill grinding and separation, and the particle size of the finished product is generally around 5-20mm;
