开路自磨流程的特点是什么
1项目：开路自磨-砾磨。
流程结构：配矿-自磨-砾磨-分级-旋流器-入浮选。
适应范围：适于处理有用矿物浸染成粒度较细、自磨介质能力较好、及其坚硬的矿石、磨矿细度、：-325目占55%，如瑞典瓦斯报铅锌矿选矿厂。
特点：自磨-砾磨直连续磨矿，砾石取自原矿破碎系统，金属磨耗低、生产费用较低，电耗较低、
备注：提取砾石较复杂、砾磨产品较粗、需将其中的较粗与较细的翻砂分别返回自磨和砾磨机中，流程复杂化、砾磨机产量较低，需要设备较多。
2项目：开路自磨-砾磨。
流程结构：自磨（带砾石提取器）-圆筒筛-砾磨-分级旋流器。
适应范围：瑞典艾迪科迪克铜矿B选矿厂。
适于中等规模的硫化矿浮选厂，
例如菲尔若黝铜矿选矿厂。
处理细粒不均匀嵌布磁铁矿，硬度f=8-12，磨矿最终产品细度、-200目占80%，例如，我国立柱铁矿阮江选矿厂之试验流程。
特点：自磨-砾磨直连续磨矿，砾石取自首段磨矿回路。
砾石取自粗碎产品、
阶段磨矿阶段流程选别、粗粒抛尾、砾石取自首段开路自磨回路。
备注：提取砾石较复杂、研磨产品较粗、需将其中的较粗与较细的翻砂分别返回自磨和砾磨机中，流程复杂化、砾磨机产量较低、需要设备较多。
通称奥托昆普型碎磨流程，80年代后在北欧推广应用。

What is the characteristic of open circuit self grinding process

1项目：开路自磨-砾磨。

1 item: open circuit self grinding and gravel grinding.

流程结构：配矿-自磨-砾磨-分级-旋流器-入浮选。

Process structure: with the ore - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -.

适应范围：适于处理有用矿物浸染成粒度较细、自磨介质能力较好、及其坚硬的矿石、磨矿细度、：-325目占55%，如瑞典瓦斯报铅锌矿选矿厂。

Adaptation range: suitable for treating the useful minerals disseminated into fine grain size, the ability of self grinding medium, and its hard ore, grinding fineness, -325 accounts for 55%, such as the Swedish gas daily lead zinc ore dressing plant.

特点：自磨-砾磨直连续磨矿，砾石取自原矿破碎系统，金属磨耗低、生产费用较低，电耗较低、

Features: autogenous grinding pebble mill grinding straight continuous grinding, gravel from ore crushing system, low wear of metal, production cost is low, power consumption is low,

备注：提取砾石较复杂、砾磨产品较粗、需将其中的较粗与较细的翻砂分别返回自磨和砾磨机中，流程复杂化、砾磨机产量较低，需要设备较多。

Note: to extract complex gravel and pebble mill grinding product is coarse, will the coarser and finer foundry returns from the mill and pebble mill, the process is complex, pebble mill yield lower and need more equipment.

2项目：开路自磨-砾磨。

2 item: open circuit self grinding and gravel grinding.

流程结构：自磨（带砾石提取器）-圆筒筛-砾磨-分级旋流器。

The process structure: self grinding (with gravel extractor) - Cylinder - Pebble grinding - Classification cyclone.

适应范围：瑞典艾迪科迪克铜矿B选矿厂。

Adaptation range: the Ai Dicko Dick copper mine B concentrator.

适于中等规模的硫化矿浮选厂，

Suitable for medium size sulfide ore flotation plant,

例如菲尔若黝铜矿选矿厂。

For example, if Phil fahlore dressing plant.

处理细粒不均匀嵌布磁铁矿，硬度f=8-12，磨矿最终产品细度、-200目占80%，例如，我国立柱铁矿阮江选矿厂之试验流程。

The processing of fine particles is not uniform. The hardness of f=8-12, the fineness of the final product, the -200 account for 80%, for example, the test procedure of the iron ore dressing plant of the column iron ore in China.

特点：自磨-砾磨直连续磨矿，砾石取自首段磨矿回路。

Features: self - grinding - gravel grinding straight row grinding, gravel from the first section of the grinding circuit.

砾石取自粗碎产品、

Gravel taken from coarse crushing products,

阶段磨矿阶段流程选别、粗粒抛尾、砾石取自首段开路自磨回路。

Stage grinding stage process selection, coarse grain throw tail, gravel taken from the first open circuit self grinding circuit.

备注：提取砾石较复杂、研磨产品较粗、需将其中的较粗与较细的翻砂分别返回自磨和砾磨机中，流程复杂化、砾磨机产量较低、需要设备较多。

Note: to extract more complex gravel, coarse grinding products, will the coarser and finer foundry returns from the mill and pebble mill, the process is complex, pebble mill yield is low and requires more equipment.
