The most intuitive change the drum dryer brings is a smaller footprint, but more productive. The new three-cylinder dryer reduces the overall size, reduces the heat dissipation area of the cylinder, and maximizes the utilization rate of heat energy. All these are important improvements that are very helpful to enterprises. Of course, for the drum dryer, the biggest improvement should be the capacity, how to improve the capacity of the drum dryer? Today we will talk about four effective ways to improve the capacity of the drum dryer.
1. Add feed device inside the drum dryer, to increase the material with high-temperature heat exposure, The feed process cannot too frequent, otherwise, small grain material will be the wind erosion. Attention should be paid to control the working frequency of the hoisting device, to control the drying speed of the material to be dried, which not only improves the drying efficiency but also makes the drying effect more thorough.
2. The drum dryer wants to be efficient, first of all, it is necessary to ensure the particle size of the feed. After crushing and grinding, if the particle size of the material is not up to the standard, it will increase the difficulty of drying, and large pieces of material in the feed process is not easy to fully be lifted up, affect the feed speed, so before feeding, particle size must be small, in accord with particle size range, the decrease of the particle size as far as possible, and ensure uniform particle size.
3. Before entering the rotary drum dryer, water control should be strict. After strict water control work, the water that could be filtered could not be put into the drum dryer. The waste of heat not only delayed the drying time of materials but also seriously affected the production cost and reduced the economic benefits.
4. Increase the speed of flue gas temperature and convection, a common way to get water to evaporate faster is to raise the temperature, but the temperature of the smoke must be operated within a certain range, because the drum dryer itself and the material has high-temperature resistance, this point should be firmly controlled, can not damage the material or the dryer by drying in a hurry.
