Industrial dryer has become more popular along with the growing needs of
heavy industry. The is one of
the traditional industrial drying equipments, according to the usage, they can
be classified into slurry dryer, coal dryer, shape-coal drying equipment.
Because the equipment is relatively large, it is also known as large-scale
dryer.
Industrial dryer features: dryer processing capacity is large, less
fuel consumption, low-cost drying. The dryer has high temperature
characteristics, and is able to use the high-temperature hot air to dry
materials rapidly. Dryer is scalability, the design allows for the production
margin, even if small output with a small increase, it doesn't need to be
replaced. Equipment adopts special designed structure, and the tugs and rolling
circle matched perfectly, so that it greatly reduces wear and power consumption.
It is anti-overload, and tube body is able to be in smooth operation with high
reliability.
Energy-saving measures for new dryer: (1) Transform the
dryer tail at low temperature drying at about 1/3 of the L-shaped lifting plate.
Generally, L-shaped lifting plate is vertical fixed in 90 °, and the plates
around can be welded in 30 °, 90 °, 120 ° angle respectively; Thus, the
spreading area enlarges by industrial dryer rotating. Consequently, the heat
exchange rate is higher; Be noted that the transformation of the industrial
dryer should consider comprehensively. If the ventilation is good, the exhaust
gas temperature is over 100 ° C, we can add a few X-shaped center sets. On the
contrary, if poor ventilation, the exhaust gas temperature is below 70 ° C, we
need to reduce groups of the X-shaped lifting plate center; It is very important
to control exhaust gas temperature. When temperature is too high, on the one
hand, it will cause high energy consumption, on the other hand it will burn the
dust bag; The other way around, it will cause a bag paste, which affects
ventilation, and makes production decline, severe dust internal component
corrosion and high maintenance costs.
2. Drying material flow speed is too
fast to control, we may add a few sets of X-shaped center lifting plate, but we
must take into account the ventilation and exhaust gas temperature; If the
conditions are not allowed, the retention ring set and location should depend on
the circumstances. However, the disadvantage is that the front part of retention
ring of the cylinder is easy wear, in that case, we can choose wear-resistant
material or thickening in this region of the plate.
Large industrial
dryer is a very important process flow in the ore dressing production line. The
dryer production line operates reliable, flexible, and adaptability with large
processing capacity. It is widely used in the field of metallurgy, building
materials, chemicals, coal washing, fertilizer, ore, sand, clay, kaolin, etc.
