摘   要
     型煤加工對于有效地利用粉煤資源和保護環境是十分重要的，在我國的能源構成中，煤炭占有十分重要的地位。據統計，在我國能源生產和消費中，煤炭約占總量的75%左右。但是,隨著采煤機械化程度的不斷的提高，粉煤在原煤中所占的比例也越來越大。粉煤比例的增加不僅降低了散煤的燃燒效率，而且嚴重地污染了環境。發展型煤是提高粉煤利用率和減少環境污染的重要途徑，研究表明，工業鍋爐,窯爐使用型煤后可比燒散煤節煤10%~27%，煙塵排放量可減少50%~60%，添加固硫劑后，二氧化硫的排放量可減少35%~50%。因此，發展型煤對我國具有十分重要的現實意義。
本設計為一種用于煤炭成型加工的高壓對輥成型機，包括有機架，定對輥軸和動對輥軸設置在機架中部，動對輥軸的兩端設置有加壓裝置，通過加壓裝置，動對輥軸能移動一定距離，在定對輥軸的軸端有同步外掛齒輪與聯軸裝置及三級設計減速器相連，在定對輥軸和動對輥軸上方的機架上安置有加料裝置。該機采用強制加料方式，液壓加載和使用安全聯軸器，從而使其型煤產品滿足生產要求。

ABSTRACT
       Coal processing for the effective use of coal resources and environmental protection is very important, Coal occupy a very important position in our energy mix. According to statistics, China's energy production and consumption, coal accounts for about 75% of total. However, as the mining mechanization of a continuous increase in coal pulverized coal as a proportion is also growing. 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, the study shows that industrial boilers, Kiln use briquette after comparable saving coal burning coal powder 10% ~ 27%, soot emissions can be reduced 50% ~ 60%. After the addition of sorbent , and sulfur dioxide emissions can be reduced 35% ~ 50%. Therefore, the development of China's coal is of great practical significance.
The design of the coal used in a high-pressure molding and processing of roll forming machines, including rack, set to roll axis and move on roller shaft installed in the central rack, moving to the ends of roller shaft equipped with pressure device, through compression devices, move to roll axis can move a certain distance. In determining the roll axis of the shaft to keep pace with the pylon gear coupling device design and three-reducer, In determining the roll axis and move right side of the roll axis rack placed on the feeder. The aircraft introducing compulsory feeding, hydraulic loading and the use of safety coupling, thus briquette products meet production requirements.
