這裡介紹一篇蘇聯科學院院士波察尼科夫對於浮選機的空氣導入速度的論述,在這裡,他雖沒有指出來一個優良浮選機所應具備的具體規範,和操作條件,但在理論上,原則上,却給予我們很大的啟示,告訴我們什麼是一個優良的浮選機,它受那些條件的支配,我们應該怎樣尋求這些條件,以增進我們浮選的操作,這對於在我們缺乏技術的今天,是很值得重视的。他在文中指出: 1.浮選機的評價是在於能否提高空氣導入速度和散入1M~3空氣所消耗的電能此; 2.增加空氣導入速度,必須提高葉輸的迥轉數,空氣導入速度是與葉輪迥轉速度的二次以上的方次成比例的; 3.葉輪的形狀,位置,大小,是影響於空氣導入速度的因素, 4.鑛液的濃度,給鑛方法,鑛液高低位置,都有關於空氣導入速度, 5.空氣導入速度的加大,可使尾鑛含有金屬降低,使精鑛品位提高。爲了使讀者更易於瞭解,原文個別的地方,略有删改,但絕大部份是按原文譯出的。我們現在各地選鑛場已逐漸開始注意磨鑛作業,給鑛作業,加藥作業並已鑊得初步成績,但對於浮選機機械性能方面,特別是對於空氣導入速率方面的研究和改進,則表現極爲不够,望能從此篇論文裡面吸取經驗,以改進我們在這方面的工作。——編者
Here is an account of Soviet Academy of Sciences Pozhanyhkov on the flotation machine air introduction speed, where he did not point out an excellent flotation machine should have the specific norms, and operating conditions, but in theory , In principle, gave us a great inspiration to tell us what is an excellent flotation machine, which is subject to those conditions, how we should seek these conditions to enhance our flotation operations, which is for us The lack of technology today, is very worthy of attention. In his article, he pointed out: 1. The evaluation of the flotation machine lies in whether it can increase the speed of air introduction and dissipate the electric energy consumed by the air of 1M to 3. 2. To increase the speed of air introduction, it is necessary to increase the amount of air transport Import speed is proportional to the impeller rotation speed more than twice; 3. The shape, position and size of the impeller are the factors affecting the air introduction speed. 4. The concentration of ore liquid, Fluid level position, there are air introduction speed, 5. Air import speed increases, the tailings can contain metal to reduce, so concentrate grade. In order to make readers easier to understand, the original text of a few places, a slight deletion, but the vast majority are translated according to the original. Now we have gradually began to pay attention to the ore dressing field, to ore operations, dosing operations and has won preliminary results, but for mechanical properties of flotation machines, especially for the air introduction rate of research and improvement, then The performance is extremely inadequate, hoping to draw lessons from this essay to improve our work in this area. --editor
