摘 要
國(guó)內(nèi)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。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。
我所設(shè)計(jì)的新型雙齒輥破碎機(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)的破碎機(jī)，很有發(fā)展前景和市場(chǎng)前景。通過(guò)資料收集、整理和設(shè)計(jì)，我設(shè)計(jì)的雙齒輥破碎機(jī)完成了。通過(guò)對(duì)資料的搜集、查找，我找到了很多對(duì)設(shè)計(jì)有用的參考資料，從而保證了設(shè)計(jì)的順利進(jìn)行。這次設(shè)計(jì)是對(duì)我大學(xué)四年所學(xué)知識(shí)的一次綜合檢驗(yàn)和全面總結(jié)。在這個(gè)過(guò)程中我學(xué)會(huì)了獨(dú)立思考、在實(shí)踐中找答案、在前人的基礎(chǔ)上求創(chuàng)新。
關(guān)鍵詞:雙齒輥破碎機(jī) 破碎 設(shè)計(jì) Abstract
Domestic current coal is broken generally using hammer breakers or toothed roll breakers. Hammer breakers is based on the high speed movement of the hammer and blow materials which is broken by impact and shear in crushing cavity.Toothed roll breakers chop materials by teeth action,then immediatly output.So its particle is well-distributed.Current toothed roll breakers is very bad in using effects because the whole structure is unreasonable and teeth is wearing out very fast.
New double toothed roll breakers which is designed by me absorb developed technology which is developed and designed as breakers.It has a bright vista in development and maket.Double toothed roll breaker which I designed is complete by collect and tidy data.I found many useful information through find and collect and guarantee the developing of design.This design is a composite test for my university knowledge.I learnt think by myself found answer in practice and created something new based on former.
Key words:double toothed breaker crush design
