2018-12-13· Humic acid. Humic acid is a kind of organic acid containing various functional groups produced by plants in the process of spoilage. It has colloidal properties. The humic acid binder has strong polarity and is easy to bond with the surface molecules or molecules in the micropores, this could lead to a certain strength coal briquette.
2016-10-22· The coal fines with peat are mix and the resulting well mixed mass is then pelletizing by the application of pressure in conventional equipment – stiff extrusion. The coal fines and peat was conditioned at various moisture contents to observe the effects on the finished product. The material then agglomerated into a granular product. The content of the granular product was 2:1, 1:1, 1:2 by ...

a humic acid binder for pelletizing of fine coal 4 main factors that will influence the coal briquette quality Coal fine briquetting conditions include briquette pressure, briquette moisture, binder type and ratio, mixing time and mixing way, material size and composition, curing way and coal briquette drying temperature, etc.
Aug 08, 2013 · The humic substance is preferably a lignite, preferably leonardite, a polyhydroxylated compound rich in humic acid. The resins formed in situ from the resin components are used as a binder in combination with a homogeneous mixture of a foundry aggregate, such as sand, and a humic substance, such as leonardite, to produce foundry products including sand/resin foundry mixes ...
Bentonite is the most widely used binder in iron ore pelletizing industry. The use of bentonite is favorable in terms of physical, mechanical and metallurgical pellet properties, however, because of its acid constituents (SiO 2 (PDF) Influence of a carboxymethyl cellulose (CMC) binder ... The main binding force in wet iron ore green pellets has been found to be the cohesive force of the ...

A humic acid binder for pelletizing of fine coal Using both laboratory and pilot scale models, research work conducted at the Department of Mining Engineering at University of Missouri-Rolla (UMR) on a single-state fine coal dewatering and briquetting technique, has shown the potential of briquetting to enhance the handling, transportation, and...
The humic acid is extracted from oxidized carbonaceous material with a mild aqueous alkali solution of, for instance, ammonia. The particulate material is blended with the extract which serves as the binder for the agglomerates. The water-resistant agglomerates are formed such as by pelletizing, followed by drying to remove moisture and solidify the humic acid binder throughout the agglomerate ...

The black humic acid material (not really an acid because of the base extraction has a pH of 9+), usually a 6% or 12% solution, was most commonly mixed with fertilizers, used in transplant solutions mixed with liquid nitrogen sources or mixed with herbicides. Because of its high pH you had to be careful because it would cause the liquid mix to jell, or precipitate out. Mixing it with ...

2017-01-31· Due to the reducing ability and bonding effect, a humic substance-based binder has been added into iron ore pellets, both as a reductant and a binder. However, humic substance-based binders were not commonly used in pelletization since some pelletizing results indicated they were not as good asbentonite or other binders.
The invention relates to a mixed pellets composed of fine coal powder and limestone powder for producing calcium carbide, which comprises fine coal powder and limestone powder, fine coal powder is mixed with limestone powder according to the weight percentage of 1:2.2 - 2.8, then the mixture is uniformly mixed by a binder with a weight of 4.6 to 5.6% of that of the mixture and 8 to 12% of ...
