How to choose the correct drying equipment, first of all to want to choose according to the properties of material itself, the dryer is used to dry fly ash mineral powder such as sand material, if you know about their material is not enough, the material can be sent to any of the dryer manufacturers, factory technical department will according to the properties of material you tested and the reasonable matching, the next step is the key to this according to make reasonable supporting the rationality of the material.
Some customers have a mixture of materials, this needs to fully understand the material, analyzes all kinds of material at the same time, to form a complete set will need to adapt to the characteristics of two kinds of material, so as to ensure the hybrid material fully dry, and ensure the material loss, not excessive drying, as much as possible to reduce the loss of material in the drying process and clean.Because most of the fly ash dryer dry fuel is coal, coal combustion can evaporate out large amounts of sulfur and ash content, they drift as air current, while some particles fly to smoke dust removal system, but if the dust removal equipment, improper will cause a large particle materials into the material into the dry ingredients, pollution materials, the person that weigh material cannot be used. Drying up and down the material drying process sequence process, in the proposed above drying equipment to dry conditions on the critical moisture content and drying curve, equilibrium moisture content, including heat heat sensitive, some material will change color after heat and decompose the metamorphism, in addition, the drying process of material shrinkage makes the molding products cracking or deformation, thus reduce the product quality or destroyed; Material combined with water screeve, it determines the dry ease, energy consumption level and the dryer is within the required time, which have greatly relations with the selection; for materials difficult to dry, for example, mainly is to give longer retention time, rather than strengthen dry outside the premise; Materials in a variety of physical properties: including density, bulk density, particle size distribution, the heat capacity and material adhesion function, such as high and low adhesion function, to front-rear and some form of dryer work has a great influence, adhesion drying process can't be serious, avoid by all means, form a complete set of dryer heating furnace is too large, it will cause material burning, although there are explosion-proof material mouth under fire tube, but if too much fire and wind enough of dust removal system, material of fly ash can cause a complete set of production line quickly drying and burning fire, ventilation rate it will cause the risk of explosion, so a substandard fly ash dryer manufacturers said nothing about safety, muddle through.
