6, automaticity is high: feed arrangement is delivered directly to material in w type blade drying equipment loading hopper, by worm drive agitating device, make material carry out fully carrying and stirring, in effective improving material rate of drying and quality, front charging or rear discharging are all that machine automatization gasifying device is without human assistance, and other drying equipment all needs manual operation, labor intensity of operating staff is large.
7, environmental protection: electromagnetism blade drying equipment heating source is that electric energy is converted into heat energy, heat utilization rate 98% is absorbed transpiring moisture by material, heat-energy losses is few, operating ambient temperature is low, and the dry run of material all completes in closed container, can not cause material dust to fly upward, can not affect the healthy of operating personnel because of operating ambient temperature and airborne dust pollution.No matter coal directly heats or converts steam to, and because equipment and this body structure of facility exist inevitable technical problem, heat utilization rate is low, and heat-energy losses is large, and operating ambient temperature is high, and on-the-spot dust pollution is large, and discharge coal smoke has a strong impact on environment.
8, operating cost is low: no matter to metal, smelting, coloured industry, low-temperature bake, environmental protection industry (epi), chemical industry.With hundred tons of meterings, adopt many warm areas electromagnetism blade drying equipment, the drying mode that production technology and traditional abc directly burn with coal, and de be take the economic performance comparison that steam is drying mode:
Following table is without under drying mode, the economic performance comparison sheet that the same material of take is raw material:
| Drying device | The direct burnup of coal | Boiler forms steam | Many warm areas electromagnetism blade drying equipment |
| Device type | abc | de | Electromagnetism blade is dry |
