The advantages of roll extrusion granulator in the production of organic fertilizer equipment

To roll extrusion granulator by low energy consumption, high energy saving, low investment and control the emissions pollution-free characteristics such as short, equipment, set of roll extrusion pelleting machine need for debugging, debugging to take accurate method, first of all, the roller spacing between should not be too small or too large, will within the prescribed scope of mediation, secondly, lateral pressure bearing cover to avoid too loose or too tight, Will cause the shaft roll deviation, the following for you to hold a detailed introduction.

First, the role of press pellet machine

1. Low energy consumption and energy saving roller extrusion granulation is a material granulation at room temperature. Compared with other methods, it does not need fuel, gas and other drying measures.

2. Steam granulation is a commonly used compound fertilizer production method in China without adhesive. After intermolecular condensation and crystallization, steam plays the role of adhesive in the middle of the production process. But during the drying process, the water inside and on the surface of the particles must be expelled, otherwise the fertilizer will be stuck and caked in the middle of the storage process. Dry granulator machine does not need another promoter, only the intermolecular force of the raw material itself is used, thus simplifying the process and lowering the energy consumption.

3. Low investment is due to the saving of drying process, low rate of return (about 15% of the total feed amount of the extruder), short process and less investment.

4. The successful use of extrusion granulation materials have more than 20 kinds of ammonium nitrate, urea, ammonium chloride, calcium nitrate, potassium chloride, potassium sulfate and so on, and extrusion granulation process can achieve the substitution of product formula in a very short time innocously, a set of equipment can produce more than 30 kinds of formula products.

5. Roller press granulator's elimination capacity is only power, environmental protection, no waste discharge, in line with the national environmental protection policy, but also in line with the enterprise environmental protection development strategy.

The design of roller press granulator

Two, the debugging method of roller extrusion granulator

 

 1. Pressure roller clearance adjustment: in production, occasionally need to improve the output or bite Angle, at this time can approximately improve the partition between the two compression shaft, improve the spacing between the active shaft and the passive shaft.  The steps are as follows: stop the machine, remove the upper rack of the two bearing seats, adjust the adjustment plate between the two bearing seats to the required thickness, the two rollers can not be enough to make the roller collision, should be combined between 0.3-1mm.

 

 2. Ball and socket counterpoint.  The ball and socket are formed by matching the pits on the surface of the main roller, so there are problems of axial and circumferential alignment:

 

 1) The axial alignment has been adjusted when installed. Generally speaking, the adjustment is not about much. When the adjustment is needed, the gland on both sides of the passive bearing seat is tightened or loosened, so as to promote the eccentric sleeve displacement corresponding to the active shaft roller.

 

 2) Circumferential alignment: the steps of circumferential alignment are: loosen the six connecting bolts between the passive gear and the conditioning sleeve, so that the adjusting device and the passive gear are slightly separated.  Since the amount of ball seat adjustment is considered in the decision and two adjustment bolts are installed, it is possible to adjust the dislocation approximately no matter how many.
