Material Features of Coal Powder Briquette Machine

Coal briquetting machine is mainly used for pressing materials with low water content such as all kinds of coal briquette, ore powder and refractory. The finished coal briquette can be used in power generation, blast furnace calcination, civil and other fields. Specifically, the characteristics of the coal powder briquette press machine (http://www.foteinfo.com/coal-briquetting-machine-58.html) material can be from three aspects:

1. Pulverized coal forming, especially without binder molding process, associated with the composition and properties of coal, including the closest relations with the elasticity and plasticity of coal. Coal flexibility, refers to the coal grain of compressive deformation in under the action of external force, when the external force to cancel after the nature of the coal particles can restore the original state. Coal plastic, refers to the coal under the action of external force can be molded into any shape, when the external force revocation, can keep the shape of nature.

2. In general, the use of plastic good, elastic small coal molding effect is good, and conversely molding effect is poor. Peat, lignite, rich asphaltine and humic acid, can be said to be its own binder, with good plastic condition, the forming effect is good. As the deepen degree of coal metamorphism, the aromatic substances increase in coal, neat rows, coal hardness and high elasticity, plasticity, the shaping effect is poor. Therefore, bituminous coal and anthracite using binder molding process.

3. Forming properties of the coal to the coal and rock components. Although it is generally believed: dull coal with high hardness, pyrolytic will form a lot of tar, conducive to forming, bright coal and vitrain plasticity is good, good for molding, the minerals composition and properties in coal, the larger influence on formability, fusain crisp, without the plastic, molding performance is poor, petrographic composition is not ideal, generally contain clay minerals...
