During operation, the new type two in one organic fertilizer granulator is prone to issues such as material accumulation within the drum, clogging at the machine head, material adhesion to the granulation disc, and blockages at the discharge port. These situations should be addressed using a systematic approach: first stop the machine, then diagnose the problem, and finally make the necessary adjustments.
First, if clogging is detected, immediately stop the machine and cut off the power supply. It is strictly forbidden to attempt to force the machine to run while it is still loaded, as this risks burning out the motor, fracturing the main shaft, or damaging the gears and liner plates. Open the inspection door and manually clear away any caked-on material, wall adhesions, or jammed blockages. Thoroughly clean out all residual material from the interior to ensure that the rotary cutters, inner liner, and screen perforations are completely unobstructed.
Second, adjust the moisture content and physical properties of the raw materials. In "two-in-one" granulation, excessive moisture is the most common cause of material adhesion to the machine, material accumulation, and screen clogging. For organic fertilizer raw materials, the moisture content should generally be controlled within the range of 25% to 35%. If the moisture level is too high, dry powder, recycled fines, or mature compost powder should be added to reduce the moisture. If the raw material contains excessively long fibers or high levels of impurities, it must be crushed and screened beforehand to prevent fibers from entangling the cutters or blocking the discharge port.
Third, inspect the operational status of the fertilizer making machine. Check the scraper blades, rounding paddles, and inner liner for signs of wear; if the scraper blades are worn smooth, they will fail to effectively scrape the material, leading to adhesion and accumulation, so they must be replaced promptly. Verify that the main shaft speed and the material feed rate are properly synchronized; feeding material too quickly can overwhelm the machine and cause blockages, so the feed rate should be appropriately reduced to ensure a steady, uniform supply. Adjust the clearance of the rotary cutters and the angle of the granulation disc to prevent the material from clumping together and failing to discharge properly.
Fourth, adhere to standardized operating procedures and perform routine maintenance. When starting the machine, allow it to run empty for a short period before gradually introducing a small amount of material. During production, avoid sudden, massive surges in the feed rate or the introduction of hard, solid lumps into the mixture. Periodically flush and clean the inner walls of the drum to maintain a smooth surface, thereby minimizing material accumulation and preventing arching (bridging) within the chamber. Maintain a low humidity level in the workshop environment to prevent the processed materials from reabsorbing moisture and adhering to the machine components.
Finally, optimize the overall process flow. Establish an appropriate ratio for incorporating recycled fines back into the mixture; adding a sufficient quantity of qualified fine powder improves material fluidity. This not only helps prevent clogging but also enhances the granulation rate and the uniformity of the resulting pellets, ensuring a continuous, stable, energy-efficient, and high-yield granulation process.
