How to make coal briquette machine with highest balling rate and capacity?

Coal briquette machine consist of feeding part, driving part and forming part three parts: feeding part main relize quantitative feeding to make sure material uniform feeding between the two rollers; driving part, main driving system: motor---V-belt---reductor---open type gear---roller; forming part main refer to main machine part, the core part is the roller. Then how to make the machine working with highest balling rate and production capacity? The followings are the details:

1.Coal briquette machine forming pressure: briquetting machine forming pressure is the key determine coal powder pressing and forming, while forming pressure also determine coal material filling on the roller ball nest degree. The more the coal material filling in the ball nest, the higher the coal material in the ball nest surfered pressure, the denser of the output briquettes. Thus, forming pressure has relative on coal material features, roller diameter and width, the two rollers distance, roller speed and ball nest shape and size, etc.
2.Coal briquette machine roller skin also have influence. Thus, you should select good quality roller skin materials, at precent, general roller skin casted by 9Cr2Mo,  with highest wear-resistance ability, improved briquette machine service life greatly.
3.The machine structure assembly also very important, each part with suit install of course can exert the best effect, if some parts with unsuit install, then will effect coal briquetting equipment forming rate.
4.Coal briquette machine roller skin ball nest size with close relative on forming effect. Briquetting forming change along with roller working speed, isn't static.
