原料通過(guò)空心軸頸給入空心圓筒進(jìn)行磨碎，圓筒內(nèi)裝有各種直徑的磨礦介質(zhì)(鋼球、鋼棒或礫石等)。當(dāng)圓筒繞水平軸線以一定的轉(zhuǎn)速回轉(zhuǎn)時(shí)，裝在筒內(nèi)的介質(zhì)和原料在離心力和摩擦力的作用下，隨著筒體達(dá)到一定的高度，新鄉(xiāng)球磨機(jī)哪個(gè)牌子好，當(dāng)自身的重力大于離心力時(shí)，新鄉(xiāng)球磨機(jī)進(jìn)口品牌，便脫離筒體內(nèi)壁拋射下落或滾下，由于沖擊力而擊碎礦石。同時(shí)在磨機(jī)轉(zhuǎn)動(dòng)過(guò)程中，新鄉(xiāng)球磨機(jī)廠家報(bào)價(jià)，磨礦介質(zhì)相互間的滑動(dòng)運(yùn)動(dòng)對(duì)原料也產(chǎn)生研磨作用。磨碎后的物料通過(guò)空心軸頸排出。the fritsch vibratory micro mill pulverisette 0 grinds your sample through impact&friction by which the mortar vibrates electro-ically&the grinding material transfers the vibrations to the grinding ball. at the beginning of the grinding， the comminution of the coarse particles is achieved by the impact effect of the grinding ball. next， the fine particles are comminuted through friction by the tumbling motion of the grinding ball as the vibrations subside. the impact energy of the grinding ball is freely adjustable thus， allowing it to be precisely adapted to the sample being ground.
(2)增加充填率和轉(zhuǎn)速率
球磨機(jī)的處理能力隨鋼球的充填率增加而增加，提高充填率增加了鋼球碎磨礦石的幾率和礦石自磨作用。鋼球充填率在45%時(shí)球磨機(jī)負(fù)荷為大，球磨機(jī)，超過(guò)45%時(shí)隨充填率的增加其負(fù)荷大幅度下降。這主要是因?yàn)殡S著充填率的增加，鋼球起拋點(diǎn)被抬高，鋼球落下的沖砸合力作用點(diǎn)加速向回轉(zhuǎn)中心靠近和超過(guò)，其合力矩大大縮短而變?yōu)閛到負(fù)值，其鋼球(含礦)砸落下的沖擊合力矩所需負(fù)荷由大變?yōu)?，直到變?yōu)橥苿?dòng)筒體轉(zhuǎn)動(dòng)的動(dòng)力(即合力作用點(diǎn)超過(guò)中心，合力矩為負(fù)值)。

球磨機(jī)(ball grinding mill)
球磨機(jī)是物料被破碎之后，再進(jìn)行粉碎的關(guān)鍵設(shè)備。
球磨機(jī)是工業(yè)生產(chǎn)中廣泛使用的高細(xì)磨機(jī)械之一，其種類有很多，
