Coke cutting machine

First, an overview

Coke cutting machine is mainly used for coke (coke, improved coke, tamping coke, coke crushing and other brittle materials). The company developed a series of CQJ is a double axis cutting coke machine and CQD gear ring type coke cutting machine, due to its breaking coke particle size uniform, a powder rate is low, easy to maintain, and unique design of tooth profile, the toothed roller service life than similar products more than twice the characteristics, has been many coking, iron and steel, casting, and other enterprises to adopt.

Cutting coke machine is mainly characterized in that the physical structure of the coke, highlighting a "cut" word, rather than double teeth roll crusher extrusion and impact, it cleverly use alternating with low axe shaped roller, high differential operation, slow speed and tooth is lifts, the fast speed of the roller is like shear to the coke was broken.

With the popularization and application of pulverized coal injection technology, coke in the blast furnace support framework becomes more important, coke need more high strength, uniform size and thermal strength. 85mm above the size of the coke structure loose, more original cracks, in charge of furnace and decline must be produced in the course of the crushed coke, directly affect the blast furnace column permeability. Coke sizing process of wear failure process completed before entering the furnace, not only significantly improves the uniformity of particle size, but also in a certain degree to improve the mechanical strength of coke (M40) and thermal strength (reaction reactivity and strength after), thus becoming the blast yield, high production of important measures.

Two, as the principle and unique performance

Coke by feeding device is uniform and continuous feeding cutting machine coke tooth roller gap, to enhance the coke crushing bite force, two teeth and for differential relative rotation, ax shaped crushing teeth points length of tooth space arranged on the toothed plate or ring gear, the coke cut and split broken. The rotation speed, the clearance and the length of the broken teeth are the main factors to determine the yield, the grain size and the rate of the powder. With ordinary double tooth roller crusher (Langya broken) crushing than CQJ/CQD series coke cutting machine has good crushing effect;

Advantages 1:

Coke broken granularity: 25-80mm size of coke accounted for more than 80%, more than 20 percent higher than the spike breaking, crushing coke strength will be improved.

Advantages 2:

The amount of coke is low: coke <15mm breaking low over 10 percentage points higher than Langya, significantly improves the utilization rate of coke.
