A sifter can help purify material prior to briquetting

Why is a sifter necessary for briquetting and for a briquette plant?



Screening of feed is essential for materials like sawdust which may contain many wooden cut pieces before being processed in the briquette plant. These screens are standard items and available in many types and sizes. These should be of enclosed type to eliminate dust problems and preferably with a self cleaning arrangement having elastic balls. Various mesh sizes of screens can be used depending upon the type of material. For sawdust a screen of 10mm may be used. For coffee husk, rice husk and groundnut shells, screens may be employed to avoid contamination by extraneous materials like stones and steel pieces, etc. And the screen mesh should be based on the largest size of the feed. Another advantage of using a vibratory screen is that it can also act as a control gravity feeder either to a hammer mill or a flash drier. For capacities greater than five tonnes/hour, rotating screens known as trommels may be employed.

It is commonly seen that an overwhelming majority of clients will take sawdust, or saw shavings or even wood chips to produce briquettes or pellets. But Prior to drying or briquetting or pelletizing for a briquette plant or a pellet plant, purification of raw material cannot be omitted. Otherwise, machines like crusher or hammer mill, or even briquette machines and pellet presses will be damaged out of use. Thus, when you take into account moisture content of material, size of feedstock, you are supposed to pay some attention to purification of raw material.
