摘   要

     在我國，隨著機械化采煤程度的提高，粉煤在原煤中所占的比例越來越大。粉煤比例的增加不僅降低了散煤的燃燒效率,而且嚴(yán)重地污染了環(huán)境。發(fā)展型煤是提高粉煤利用率和減少環(huán)境污染的重要途徑。
對輥成型機是應(yīng)用最廣泛的型煤成型設(shè)備。針對現(xiàn)有對輥成型機的發(fā)展，目前我國現(xiàn)有的對輥式多為低壓成型設(shè)備。由于成型壓力低,生產(chǎn)型煤所需的粘結(jié)劑用量大,致使型煤生產(chǎn)成本較高,這種狀況也影響了我國型煤工業(yè)的發(fā)展。
本設(shè)計中的對輥成型機，采用螺旋強制加料，提高成球強度；采用液壓加載，平衡成型反作用力，并且當(dāng)有尖硬物料進(jìn)入型輥間隙時，自動退讓，能保證成型機安全運行；采用安全聯(lián)軸器，提供平移退讓和過載保護(hù)，保證成型機安全運行；在輥面設(shè)計中，采用八塊型板拼裝結(jié)構(gòu)，便于安裝和更換。
關(guān)鍵詞：對輥成型機 ；同步齒輪傳動 ；強制加料 ；液壓加載

ABSTRACT
      In China, with the mechanized mining in increasing coal in the coal share of the increase. Coal proportion of the increase not only reduced the casual coal combustion efficiency, but also seriously polluted the environment. Development of coal briquette is to improve utilization and reduce environmental pollution in important ways. 
Right roll forming machine is the most widely used Briquette Production equipment. Roll against the existing molding machine development, China's existing right to roll over low pressure molding equipment. Due to the low pressure molding, briquette production of large amount of binder, resulting in higher coal production costs, This situation also affected the coal industry in China's development.
The design of the roll forming machine, used spiral compulsory feeding, raising the ball into strength; Used hydraulic loading, balancing forming reaction force, and when there are sharp or hard-roll materials into space, automatic concession, which would ensure the safe operation of forming machine; safe coupling, provide translation and Overload Protection concession to ensure the safe operation of forming machine; the roller surface design, using eight plate assembly structure, easy installation and replacement.
