花岗岩圆锥破选型指南 · 500 t/h
Granite Cone Crusher Selection Guide

花岗岩(Granite)——抗压强度约 150 MPa,普氏硬度 f=12-14,磨蚀性高(high)。 给料 undefined mm → 成品 31.5 mm,目标产能 500 t/h。

物料特性 / Material characteristics

花岗岩是粗粒结构、磨蚀性强。它是全球用量最大的硬岩骨料,所以花岗岩线通常按大产能配,筛分面积要给足。

Granite is coarse-grained and abrasive. It is the highest-volume hard-rock aggregate worldwide, which is why a granite line is usually specified at high capacity with generous screening area.

选型要点 / Selection notes for Granite

1. Size the screen properly

花岗岩线的瓶颈常在筛分而不是破碎。筛分面积不足会让循环负荷飙升。

2. Watch the flake content

花岗岩节理发育,针片状含量偏高时考虑整形段或调整腔型。

3. Plan for liner rotation

花岗岩磨损均匀性较好,衬板可以翻转使用延长寿命。

常见问题 / FAQ

What cone crusher for a 500 t/h granite plant?

For hard, abrasive granite a single-cylinder hydraulic cone crusher in the MC cavity is the usual answer. The plugin computed NH700 MC at CSS 15.8 mm, 2 units, for 500 t/h — but you must confirm against MACKORN's cavity x CSS table before ordering.

Why two stages and not three for granite?

Total reduction ratio decides the stage count: granite from 600 mm to 31.5 mm is about 19:1, which two stages handle. Iron ore or copper ore at 40-60:1 needs three.

What cavity and CSS does the plugin recommend for granite?

NH700 MC 腔 @ CSS 15.8 mm,277-395 t/h,630 kW,2 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.

What is the total reduction ratio for 500 t/h of granite?

Feed undefined mm to product 31.5 mm gives a total ratio of 19.05, which the plugin resolves into 2 stages.
