Problems that need notice in slime dryer drying process
In the process of selecting slime dryer equipment, we can depend on the model
and material scope to choose specific options, it can be said, the material
properties play a very important role in the process of drying
equipment selection; regardless of mixing the dried material to slime dryer
even use slime dryer as the household dryer for drying things at home, they are
bad to materials, does not say causing material damage, but also often reach the
drying requirements! Material issues that need attention in the drying
process:
1, requirements on recoveries of drying materials; drying method of
drying materials or related equipment; drying material value of the goods and
the influence of the drying effect: equipment moisture, pollution, temperature,
abrasion, chalking, crushing, rehydration influence on the value of the goods;
drying process for drying materials in the upper and lower sequencing technology
and the nesting ground state.
2. The material morphology: large molding wood,
ceramics, and flaky, fibrous, granular, fine powder until the paste and liquid
materials are industrial materials need to be dried; dryer is chosen first based
materials morphology;
3, material characteristic during the drying process:
in the drying conditions, drying curve, the critical moisture content,
equilibrium moisture content, including heat-sensitive, some materials after
heating can be discolored and decomposition deteriorated; in addition, in the
drying process, the contraction of the material will make molded articles crack
or deformation, so that the product quality is reduced or even scrapped.
4,
the ground state of the materials and moisture-binding: it determines dryly
degree of difficulty, the level of energy consumption, and places of residence
time required in the dryer, this close to selection greatly.
5, a variety of
physical properties: density, bulk density, particle size distribution, heat
capacity, and material adhesion functions; the level of adhesion function
greatly impact feeding and discharging, if severe adhesion, drying process can
not be carried out;
6, geographic characteristics of drying materials: the
drying material morphology, water content, water content nature, crystal water,
particle size, bulk density, viscosity, heat-sensitive, softening point, the
phase transition point, thixotropic, toxic, corrosive, odor, combustible,
explosive static, breathable, reunion, crystal etc. Overall, select slime drying
machine according to the respective local energy and its own characteristics
and advantages so that create the largest value.
