Debugging method of low-energy-consumption and high-yield double-roller squeezing fertilizer granulator

2021/03/26
The granulation production process of the double roller granulator is short, energy consumption is low, and the output is large. The direct granulation of dry powder does not require the subsequent drying process, which is more conducive to the connection and transformation of the existing organic fertilizer equipment production process. The granule strength is high and the bulk density is high. Larger than other granulation methods, it is especially suitable for increasing the accumulation ratio of products, with large operating flexibility, wide application range, and adjustable extrusion pressure.
The double roller granulator has the characteristics of low energy consumption, high energy saving, low investment, simple operation, and pollution-free equipment emissions. The installation of the roll extrusion granulator needs to be debugged, and the correct method should be adopted when debugging. First, the spacing between the press rolls should not be too small or too large, and should be adjusted within the specified range, and secondly, the bearing seat side To avoid too loose or too tight the pressure cover, it will cause the shaft roller to deviate. The following is a detailed introduction for you.
Debugging method of low-energy-consumption and high-yield double-roller squeezing fertilizer granulator
The debugging method of the double roller extrusion granulator:

1. Press roller gap adjustment: In production, sometimes it is necessary to increase the output or bite angle. At this time, the distance between the two compression shafts and the distance between the driving shaft and the driven shaft can be increased. The steps are as follows: stop fertilizer granulation machine, disassemble the upper racks of the two bearing seats, adjust the adjustment plate between the two bearing seats to the required thickness, and the rollers cannot collide between the two rollers, and the minimum should be kept between 0.3-1mm. can.

2. The alignment adjustment of the ball socket. The ball socket is formed by the indentation of the concave sockets on the surface of the main roller, so there are problems of axial alignment and circumferential alignment:
1) The axial alignment has been adjusted during installation. Generally speaking, the possibility of adjustment is not great. When adjustment is required, tighten or loosen the glands on both sides of the passive bearing seat to push the displacement of the eccentric sleeve and the active shaft roller. correspond.
2) Circumferential alignment: The steps of circumferential alignment are: loosen the six connecting bolts between the driven gear and the adjusting sleeve, so that the adjusting device and the driven gear are slightly separated. Since the ball seat adjustment amount is considered in the design, and two adjustment bolts are installed, the dislocation can be adjusted regardless of the dislocation.
