As a Baiye assistant, polyacrylamide plays an important role in many industries
Today, Hongchang chemical will analyze the situation of flocculant polyacrylamide used in coal washing plant
What is the dosage ratio of polyacrylamide used in coal washing?
When using polyacrylamide in sewage treatment of coal washing plant, we should mainly determine the dosage and analyze the observation effect in the process of use
The specific gravity of coal is smaller than that of water
The buoyancy of water is used to separate coal and coal gangue
This process is called coal washing
Coal washing is an industrial process to eliminate impurities in raw coal or classify high-quality coal and low-quality coal

Detailed rules for consumption of polyacrylamide for sewage treatment of coal washing plant:
1
Polyacrylamide for slime water treatment is specially configured according to the water quality and coal quality of coal washing plant
Before use, the proportion of products shall be determined according to the test results of slime water

2
The applicable occasions are all tailings sedimentation tanks of coal preparation plants requiring rapid settlement

3
The proportion of the product is three thousandths
3000 grams of polyacrylamide is added to each ton of clean water, fully stirred and dissolved, and then added to the tailings water at the proportion of three thousandths

4
The actual amount of polyacrylamide for slime water treatment depends on the coal quality, the concentration of slime in tailings, the residence time of slime water in sedimentation tank and other factors

Precautions for the use of polyacrylamide for sewage treatment in coal washing plant: polyacrylamide first needs to be fully hydrolyzed, which takes a long time
If the hydrolysis is not sufficient, the effect is not good
The hydrolysis process can not be strongly stirred, but can only be slightly stirred, otherwise the molecular chain will be interrupted and the use effect will be affected
The hydrolysis is generally configured to a concentration of 1ppm, and the proportion of 1G dry powder per cubic meter of slime water is generally used, There should be sufficient contact time for adding slime water, which can be considered to be added at the tail ore tank of flotation machine

Select appropriate polyacrylamide products
During the use of polyacrylamide solution for sewage treatment in coal washing plant, pay attention to the full dispersion of the solution in peat water
On the one hand, do not stir too fast to avoid damage to flocs; On the other hand, pay attention to the mixing uniformity of polyacrylamide solution and slime water, so that the surface of slime water can be in full contact with polyacrylamide solution, so as to make its charge matching better, which is conducive to flocculation and separation

The selection of appropriate coal washing flocculant can get twice the result with half the effort
A small test should be carried out according to the coal quality of coal washing to solve the problem of type selection
The use requirements of polyacrylamide for coal washing are also very strict
