玄武岩是细粒火山岩。抗压强度高 + 磨蚀性强,这两点共同决定衬板寿命——在这种料上,锰钢牌号和腔型比标称产能更重要。
Basalt is fine-grained volcanic rock. Its high compressive strength combined with high abrasiveness is what wears a cone liner out — manganese grade and cavity profile matter more here than headline capacity.

## 破碎筛分生产线配置 · 300 t/h
- 给料 500 mm → 产品 31.5 mm,总破碎比 **15.87**
- 推荐段数:**2 段**(两段:粗碎 + 中细碎)
### 分段计划
| 段 | 工序 | 给料 mm | 产品 mm | 破碎比 | 职责 |
|:---|:---|:---|:---|:---|:---|
| 1 | 粗碎 | 500 | 125.5 | 3.98 | 粗碎:颚式/旋回破碎机 |
| 2 | 中碎 | 125.5 | 31.5 | 3.98 | 细碎:液压圆锥破(本品为美矿主营段) |
### 液压圆锥破选型
- 中碎段首选:**NH700 MC 腔 @ CSS 15.8 mm,277-395 t/h,630 kW,1 台**(单台需求 300 t/h;依据:系列区间近似)

### 筛分与输送
- 筛分处理量 375 t/h;建议筛分面积 **12.5 - 31.2 m²**(效率 0.85-0.92)
- 输送设计能力 345 t/h;建议带宽 **1600 mm**,最大倾角 18-20°

S1 厂商腔型×CSS 详表(硬数据)还是系列区间近似(须 MACKORN 技术复核)。
给料粒度超过约 350 mm 时圆锥破无法直接吃料——插件会拒绝并提示前段预筛分或改用粗碎设备,这是正确行为。
偏高硬度 + 高磨蚀 → 选腔型池的偏粗端(EC/MC),避免细腔导致衬板局部过度磨损。
CSS 压得越小,单位能耗和衬板磨损上升越快。先用"能做出目标粒形的最大 CSS",再按实际产品曲线微调。
玄武岩建议用加厚型衬板或提高锰含量,牺牲一点腔容换寿命。
Yes — a single-cylinder hydraulic cone crusher is the standard choice for basalt in the secondary and tertiary stages. Basalt is hard and abrasive, so cavity selection and liner grade drive the economics more than nominal capacity.
No. A cone crusher is a secondary/tertiary machine. The plugin rejects feed above roughly 350 mm and tells you to pre-screen or add a primary crusher — that is the expected answer, not an error.
NH700 MC 腔 @ CSS 15.8 mm,277-395 t/h,630 kW,1 台. Treat it as a starting point: the plugin marks whether the basis is MACKORN's cavity x CSS hard data or a series-interval approximation that needs technical review.
Feed undefined mm to product 31.5 mm gives a total ratio of 15.87, which the plugin resolves into 2 stages.
