Drying machine trough, most of the use of iron trough, due to iron chute under the high temperature environment and the material erosion, often corrosion and sealing 
off, not only affect the production and not easy to maintenance, especially using boiling furnace factory is obvious). The Henan Changxing refractories factory is proposed under the trough using refractory brick masonry, and achieved good results, for reference.
off, not only affect the production and not easy to maintenance, especially using boiling furnace factory is obvious). The Henan Changxing refractories factory is proposed under the trough using refractory brick masonry, and achieved good results, for reference.
Masonry materials: there are generally two kinds of refractory brick (T – 3, T – 19 or T – 38).
Masonry method: in the furnace near the dryer section, the center line of the dryer is a center, a small hole, the hole of the width, height and length of the drying machine feeding port size to determine the size of the. As with diameter of 1.5m x 12m drying machine, for example: the machine into feed inlet diameter 1000mm, this hole width desirable 800mm, hole height for into the outlet of 2 / 3 length from the drying head count, brick is the dryer in the rotation can’t touch bricks as the beginning. Hole pier to furnace direction extending about 800~1000mm. It into a small hole, hole at the center of the above built a tilted 45 degrees, 300mm wide groove can be in again. During the production, from the conveyor to the top notch pipe butt on it.
The results show that the use of refractory brick masonry dryer material tank has the
following advantages:
following advantages:
The high temperature, compressive strength, corrosion.
After the II masonry, brick almost to the outer edge of the dryer are all covered, drying head is not easy to burn, deformation, and prolongs the service life of the dryer.
(3) The fire heat and energy concentrated walk toward the middle, eliminate the air leakage and material leakage phenomenon, the flame in the hearth into the drying machine is very far.
Also such masonry method and on into the air without any effect, but without anything blocked, the slot into the fire hole effect is more ideal. The transformation of this groove is less; l ~ 2d can be completed.
