Coal slime has many shortcomings such as high moisture, high viscosity, large water holding capacity, and low calorific value, which makes it difficult to achieve industrial application. It has been rejected by the power industry for a long time. If the coal slime can be dried in the coal slime dryer to produce industrial coal, it can not only save energy, improve efficiency, but also reduce the environmental pollution of the mining area, and the maintenance of the coal slime dryer is particularly important, then How to maintain the high-efficiency and energy-saving coal slime dryer daily?
1. Daily maintenance of coal slime dryer
Each shift (calculated as 8 hours) must clean the front and rear dust nets at least twice to maintain good ventilation performance.Dust adhering to the surface of the machine must be cleaned once a day. Prevent the accumulation of hair dust and spontaneous combustion at high temperatures.Open the valve of the steam cooling system after get off work every day to prevent the accumulation of condensed water and affect the use effect and service life.
2 weekly maintenance of coal slime dryer
Check the transmission system once a week: whether the V-belt is too loose, if it is too loose, tighten it properly, and replace it if it is excessively worn. Check whether the connecting bolts are loose and tighten them in time.
3. Monthly maintenance of coal slime dryer
Lubricate the rolling bearings of the primary and secondary shafts once a month.Clean the steam cooling system once a month to remove dust deposits and ensure a good steam cooling effect. Check and maintain main motor, blower motor and exhaust fan motor monthly. Check and clean the appliances in the control box once a month.
The maintenance of the high-efficiency and energy-saving coal slime dryer requires careful attention on weekdays. Before use, the operator must read the operation manual of the equipment in detail. Before the material is dried, the pumice debris in the goods should be cleaned up, and then put into the drum. So as not to wear and block the drum and affect the service life of the high-efficiency and energy-saving coal slime dryer.
