摘   要

      工业型煤是一种清洁、高效的新型燃料,广泛应用于电力、冶金、铸造、化肥等工业领域。目前我国工业型煤的生产工艺主要采用粉煤添加粘结剂和一些辅料低压成型,以往的研究主要集中在成型工艺和粘结剂方面,对成型机械的研究开发甚少。事实上,成型机械是型煤生产的关键设备,
本文描述的是一种中高压对辊成型设备的设计与实现。
成型力是由液压系统提供，可以产生很高的成型压力。而且有液压的防止过载功能。提高了型煤的质量还能有效保护机器，不受意外伤害。
煤要成型就要有准确的对中性，该传动系统采用同步齿轮箱，而且采用帐套连接技术可以进行少量的无级调节，保证有良好的同步对中性，提高了机器的运转精度和型煤率。
采用变频调速螺旋加料装置。使送料连续，还有一定的预压力。变频调速可以根据产量,可以灵活地调整加料螺旋的旋转速度,以满足对辊成型机对加料速度、加料压力及物料密度的匹配要求,提高了工业型煤的成球强度
机架采用螺栓拉紧，不但使得制作简便、拆装方便,而且机架的承载能力也强,满足对辊成型机的工作要求。

ABSTRACT

 Industrial briquette is a clean, efficient new fuel, widely used in the electricity, metallurgy, casting, chemical fertilizers and other industrial fields. At present, China's industrial briquette production techniques used mainly coal binder and add some excipients low pressure molding, Previous studies focused mainly on forming processes and binder, the right molding machinery little research and development. In fact, molding machinery is briquette production of key equipment.
 This paper describes a high-pressure China to roll molding equipment design and implementation
 Forming power of hydraulic systems can produce high pressure molding. But also to prevent the hydraulic overload functions. Improve the quality of coal can effectively protect machines from accidents.
 Coal will be forming an accurate pair of neutral, the use of synchronous transmission gearbox, Zhang Tao and using technology for linking a small number of no-regulation, to ensure a good synchronization of the neutral, improve the functioning of the machine precision and briquette rate.
 Using variable frequency spiral feeder. Feeding enable continuous, there will be some pressure on the advance. VVVF can output and the flexibility to adjust the feed screw rotation speed, to meet the roll forming machine for the feeding rate, feed pressure and density of materials matching requirements, enhance industrial briquette ball into strength
 Rack with bolt taut, not only makes the production of simple and easily reassembled, and the rack-bearing capacity, meet the roll forming machine and job requirements.
