While as we all know that, the papers for different uses have different characteristics, the quality of paper briquette machines in the market are not the same and that can be told by the density of the paper briquette product produced and the service life of the machine.
Normally, the briquette density is one key figure of the briquette quality, briquette with higher density is going to burn longer and the takes less space in transportation and the storage, but sometimes the density might cause the problem of low combination effect, it can be fixed with the help of binder, if binder is not one allowed, then the raw material choosing has to be very careful, the paper with high lignin content is also able to achieve a perfect combination effect. As to the briquette maker, you should check how much pressure can it provide, although you might not need the largest pressure it provides, but it can reflect the quality of the machine. Compared with other paper type, the junk mail paper is easier to be processed.
