What affects feed machinery production and processing?
Feed flow control
In order to make the granulator non-stop balanced full-load work, it is necessary to make the flow of materials into the granulator to meet the needs of granulation, feeding structure to effectively eliminate the phenomenon of intermittent feeding due to agglomeration. SZLH40 granulator, for example, the material flow should not be less than 10T / H, to stabilize the material flow in actual production by adjusting the feeder, it is more reasonable to install a buffer warehouse directly above the granulator, if not set up the buffer warehouse, or buffer warehouse and feeding up a longer connecting pipe (0.5m or more), it is difficult to ensure that the amount of material coming to a stable. Many feed mills in the granulator production efficiency is not normal, just busy in the granulator itself to find the reason, and ignored the incoming factors, in fact, many times the decline in production efficiency is caused by the incoming flow is not stable. Generally speaking, when the granulator is running smoothly and normally, the steam supply is sufficient, the feed gate is all open, the feeder speed is adjusted to the rated value and the main motor work is always less than the rated value of electricity, you can judge the incoming material flow is insufficient, this time should be to find out the reasons for the treatment of the symptoms.
Production operation
Correctly control the gap between the pressure roller and the pressure mold. Roller die gap is too small, the pressure mold and pressure roller easy to wear, and ultra-noise; gap is too large, it affects the material extrusion. Generally controlled at 0.05 ~ 0.30mm. adjustments can be measured with a tape measure, no tape measure can also be visually. To the new mold new roller, for example, visual pressure mold pressure roller seems to rely on non-reliable, but no material when the host rotates the pressure mold can not drive the pressure roller is appropriate, especially stressed that the new mold should be equipped with a new roller, the gap should be smaller. In addition, the pressure roller to add enough grease (usually choose high-temperature lithium grease No. 7), to avoid burning the bearings due to high temperature. At the same time also need to feed scraping to adjust, otherwise it will make the material difficult to enter the pressure roller and die between, part of the material will be from the die cover ship string out, the formation of particles pulverized grain high, adjust the results should be scraped to the upper edge of the curve and the die, die cover gap is basically controlled in the 2 ~ 3mm between, scraping to the front end of the die into the pressure die should not be more than the location of the die inner hole of the sinking cut groove. Pelletizing machine parts adjusted, you can open the granulator. First open granulator, tempering device, feeder, this time the feeder should be in a small feed state. In order to prevent the machine debris into the mold, you should open the operating door on the outside of the machine discharge door, drain the machine mixed with debris material. After the debris is clean, the material can be introduced into the press mold. For caution, the hand should hold the machine outside the discharge door handle, first let part of the material into the die, and then observe whether there are particles smoothly out of the mold, and at the same time pay attention to the current changes. If the pellets can be produced normally, the current is smooth, the fluctuation is not big, and the rated current is not reached, then you can increase the flow of material and increase the amount of steam at the same time.
