摘 要
顎式破碎機(jī)經(jīng)過(guò)100多年的實(shí)踐和不斷改進(jìn)，其結(jié)構(gòu)已日益完善。它具有構(gòu)造簡(jiǎn)單、工作可靠、制造容易、維修方便等特點(diǎn)。所以，至今任然是粗碎和中碎作業(yè)中最重要和使用最廣泛的一種破碎機(jī)械。它不但在建材工業(yè)，也在冶金、煤炭、化工等工礦企業(yè)中被廣泛地采用著。顎式破碎機(jī)主要用來(lái)破碎應(yīng)力不超過(guò)200Mpa的脆性物料。如鐵礦石、金礦石、鉬礦石、銅礦石、石灰石和白云石等。在建材工業(yè)中它主要用來(lái)破碎石灰石、水泥熟料、石膏、砂巖等。
近年來(lái)，隨著露天開(kāi)采比重的增加和大型挖掘機(jī)、大型自卸汽車(chē)的采用，露天礦運(yùn)往破碎車(chē)間的礦石粒度達(dá)1.5～2m。同時(shí)被采礦石的品位日益降低，要保持原有生產(chǎn)量就必須大大增加開(kāi)采量和破碎量。因而就使破碎機(jī)朝著大型、高生產(chǎn)率的方向發(fā)展。目前，國(guó)外生產(chǎn)的簡(jiǎn)擺顎式破碎機(jī)的最大規(guī)格是2100mm×3000mm，復(fù)擺顎式破碎機(jī)的最大規(guī)格是1500mm×2000mm。

關(guān)鍵詞：粉碎，顎式破碎機(jī)，破碎。









Abstract
The structure of jaw type crusher has been being perfected though unceasing improvement and the practice of process with more than 100 years. It is characteristic with simple structure, working reliablly, producing easily，maintenance conveniently and so on. Therefore, so far it still is a kind of the most important and extensivily used crusher weapons ，which work in crushing for rough powder and medium-sized powder .It is extensively used not only in building material industry , also in the metallurgical industry ，in coal industry ，in chemical industry and other industrial and mining enterprises. Jaw type crusher is mainly used in crushing the brittleness material which stress does not exceed 200 Mpa. As Iron ore, golden ore, molybdenum ore, copper ore, limestone，and so on. In building material industry, it is mainly used in crushing limestone and cement , plaster ,sandstone etc..
In recent years, along with the increase of the proportion of opencast working , adopting of large scale exavator and large scale dump truck, the ore transported from open-cast to broken workshop which size reach 1.5 ～ 2 m. At the same time, the grade of mining stone is reduced increasingly, we must increase mine quantity and broken quantity greatly in order to maintain original production. Thus the crusher is developing towards large-scale, the high productivity direction. Now, Abroad, the biggest specifications of letter pendulum jaw type crusher of production is 2100 mm×3000mm and the jaw type crusher of compound pendulum is 1500 mm×2000mm.

Key word: Crush , the jaw type breaker , broken.
