摘 要
我國(guó)目前原煤的破碎一般采用錘式破碎機(jī)或齒輥式破碎機(jī)。錘式破碎機(jī)是以高速運(yùn)動(dòng)的錘頭打擊物料，在破碎腔內(nèi)受到相互破碎沖擊和剪切，可控性很差，容易產(chǎn)生過(guò)粉碎，而且對(duì)入料度有限制，不適合煤炭的粗、中碎作業(yè)。而齒輥式破碎機(jī)是在齒的作用下對(duì)物料進(jìn)行劈碎，破碎后的物料直接排出，因此破碎粒度比較均勻。目前的雙齒輥破碎機(jī)由于整體結(jié)構(gòu)的不合理和破碎齒磨損快不能修復(fù)等原因，使用效果大大降低甚至很差。2PGC—450×500新型雙齒輥破碎機(jī)是在吸取國(guó)內(nèi)外先進(jìn)技術(shù)的基礎(chǔ)上研制和設(shè)計(jì)出來(lái)的高強(qiáng)力破碎機(jī)，很有發(fā)展前景和市場(chǎng)前景。

Abstract
My current coal was broken generally using hammer-Breakers or teeth roller-Breakers. Hammer-Breakers is the dead against high velocity materials in the shattered debris impact and sheared by mutual broken, controllability poor had to smash easily, but there are restrictions on the Liaodu not suitable for coal rough, Chinese broken operations. And teeth roller-Breakers teeth in the role of materials returned broken, the broken material directly emit, broken granularity more evenly. The current two-tooth roller Breakers and the overall structure of the irrational can not repair broken teeth wear faster reasons, the use of significantly reduced or even poor. 2PGC-450 x 500-double teeth roller Breakers in lessons and on the basis of advanced technology and designed to develop high-strong Breakers, a development prospects and market prospects.
