Gypsum briquette machine – how to set up a gypsum briquette plant
Gypsum briquette machine is used to briquette gypsum to make it with shapes like ball, pillow. etc. Most of the gypsum used are the desulfurization gypsum, so it is always called as desulfurization gypsum briquette machine for this wide usage. Besides, another common gypsum for briquetting is phosphogypsum from the fertilizer plant.
The desulfurization gypsum
Desulfurization gypsum has another name as FGD gypsum (flue gas desulfurization gypsum), most of which comes from the power station as a byproduct. It’s chemically nearly identical to natural gypsum from the mine, but with higher purity and fineness. Also with higher moisture (12-17%). It will show different colors from the fuel we used and the dust collect affection we get.
Why make gypsum briquette
These desulfurization gypsums, with powdery status, is hard for transportation and storage. Dust pollution is also caused by it. Making briquette from this raw material will help to solve these problems.
Those briquettes, after carefully dealt with, can be used to make a lot of product.
Here are some of the examples:
- used to produce cement retarder;
- make gypsum;
- produce gypsum board;
- used to make building plaster;
Turn these waste gypsum to valuable sources create a way for recycling and make value for us.
The gypsum briquette plant process
Gypsum briquette making follows a very efficient way on briquetting as no binder is needed for this process.
Normally the following equipments are needed to set up the plant.
The whole process normally follows this way:
Raw Gypsum ⇒ Feeding ⇒ Drying ⇒ Compacting ⇒ Briquetting ⇒ Drying ⇒ Final Product
The raw gypsum first fed in the line with a feeder, then it comes to a dryer(normally we choose rotary dryer) to reduce the moisture, the dried gypsum powder then come to the compacting machine(s) for getting a better standard by output the air between the raw material, these gypsums then is suitable for briquetting and briquette by a gypsum briquette machine, the output briquette then put in a dryer to reduce its moisture for our standard for storage or selling or something we want to.
The main machines’ function and instruction in the line
Dryer (first section for raw material)
Rotary dryer with special designed structure will afford this work. Though the raw moisture is higher for briquetting, the good news is it’s only a little high, for a common capacity gypsum briquette line, a small rotary dryer will be enough for us to make this work done.
Gypsum is a kind of material which is hard to be directly briquette. Lots of the air/gap between the raw material particles makes them hard to form together, by using a compacting machine (density adding machine), most of the air/gap will be brought away by this preliminary briquetting process and make it easy for briquetting. Set up compacting machine for more than 1 set will help to improve the performance on the final briquetting process. This type of machine is key for the binder free way of gypsum briquetter.
Roller briquette press machine is used to make gypsum briquette, those gypsum roller presses are with special design for getting a better performance and longer service life. The gypsum fed by a conveyor to the hopper of the briquette machine and comes out with ball size larger than 10mm as the gypsum briquette. Use the gypsum type roller briquette press help to increase the forming rate and with make the briquette with proper strength.
Dryer (last section for briquettes)
The briquette output from the briquette making machine, and comes through a dryer for a quick drying (1-2 hours), optional dryers are available. Like vertical dryer, belt dryer. This quick drying process makes the briquette useful in a short time. Or you may set up a drying house for other drying ways.
Gypsum briquette machine for sale
The waste gypsum is a source where you can find extra value with the proper process to deal with. It not only helps to make a profit from it but also makes an environment protection by reducing the cost on natural gypsum. For the manufacturers like cement plant who buy these waste gypsum briquettes, it also helps them to reduce their running cost. It’s really a good industry to involve in.
