The increase of regular maintenance coal grinding powder spraying machine and maintenance work, accumulated 2000 hours running of coal mill proposal after each increase of 1000 hours for a check
To replace the damaged parts or adjust the gap between the grinding roller and the grinding bowl according to the wear condition.
A coal powder machine by feeding part, discharging part, turning part and driving part (reducer, small gear, motor, electric control) and other major department
Component composition. The hollow shaft is made of steel castings, the liner is detachable, rotary gear hobbing with casting, shell lining with wear-resistant, has
Good abrasion resistance. Mill is the coal crushing and grinding coal machine, it is an important auxiliary equipment of pulverized coal furnace. Coal grinding process is coal
The process of crushing and increasing surface area.
Two, coal powder machine consists of a horizontal rotating device, outer gear, two warehouses, lattice type ball mill. Material feeding device
The hollow shaft of the feeding material is uniformly entered into the first bin of the mill, and the bin has a stepped lining board or a corrugated lining board.
Dynamic centrifugal force will be brought to a certain height of the ball after falling, the material to produce a pounding and grinding effect. Materials in the first position to achieve a rough grinding, the
A single layer of the silo is entered into the second bin, which is inlaid with a flat lining board, and a steel ball is in the inner of the bin. Powdered thedischargegratedischarge
, complete the grinding operation.
Energy efficient coal powder spraying machine outer steel shell, the fuel is coal, is a key source of industrial kiln, grinding and centrifugal hammer
Combined mechanical ventilation. Used for crushing coal and will burn the various furnace, boiler, kiln, and pulverized coal is directly injected into the combustion chamber.
The fire (annealing) kiln for factories and mines, enterprises and institutions as various furnaces supporting
Equipment assembly: installed in the concrete foundation should be adjusted to the level of the anchor bolt is strong, the host pulverized coal separator connected with hose and ignition furnace
Connecting and adjusting the installation height, the furnace base should be stable and fixed on the brick concrete structure or the steel structure base.
Ignition furnace chamber at the bottom of the air inlet pipe, ignition furnace and the combustion chamber is connected into combustion chamber into the fire hole, 150-200mm. Combustion chamber and heat source equipment connection
.
Working process: the combustion chamber will be added to the coal into powder and mixed with excess air, sprayed into the combustion chamber is completely suspended combustion, with heat
High efficiency, increase production and energy saving, coal saving 60-70%, drying production units increased by 214%, and the production is not affected by rainy weather, no waste gas discharge,
