Abstract

A working head of porous coal rod forming machine is composed of a casing with locating cover and material compressing tray and a sealing ring. Said material compressing tray has the slot-type discharging regions which are uniformly distributed along a ring and have discharging holes. A rod sleeve passes through said discharging hole. The discharging holes are distributed on the peripheral circumference of said casing.

Description

technical field [0001] The invention relates to an accessory of a coal rod machine, in particular to a machine head of a porous coal rod forming machine used in the nitrogen fertilizer industry for extruding pulverized coal into round rods. Background technique [0002] The head of the existing coal rod forming machine generally has an integral structure with the shell, the shrinking tray and the rod sleeve, and the discharge holes are arranged on the same circumference in a single way. The head has a simple structure and a single function. The amount and operating current are much lower than the rated value. During use, the discharge hole is easily blocked, the operation of the equipment is unbalanced, the coal rod is uneven and fragile, the electric sand is high, the rod sleeve is seriously worn, the maintenance cycle of the machine head is short, the labor intensity of the operator is high, and the cost is high. Contents of the invention [0003] The object of the pres...
