What is the dry granulation craft of double roller pelletizer?

Dry rolling granulation mainly relies on external pressure to force the material to pass through the gap between two relatively rotating rollers and forcibly compress it into pieces. During the rolling process, the actual density of the material can be increased by 1.5 to 3 times. So as to meet the specified particle strength requirements. The dry rolling granulator can compress the powdery materials with moisture content ≤5% into flakes or blocks, and then through the process of crushing, granulating and sieving, the flake materials can be turned into granular materials that meet the requirements of use.   Under normal circumstances, the subsequent drying and cooling steps can be eliminated.

The raw materials are evenly fed into the feeding hopper through a quantitative feeder. The dry extrusion type of granules making facility uses a pair of rollers with holes, leaving a gap between them, and the two rotate in opposite directions at the same speed.

One set of roll chocks does not move in the rack, while the other set of roll chocks moves upstream on the rack guide rail, and presses against each other by hydraulic cylinders.

Many holes of the same shape and size are regularly arranged on the surface of the roll, and the troughs are aligned with the troughs. At this time, the dry powder material enters the double roller granulator of extrusion craft continuously and uniformly from the top of the two rolls by its own weight and forced feeding. The material flows freely first, and then is gradually bitten into the trough by the rolls after entering the biting area.

With the continuous rotation of the roll, the space occupied by the material gradually decreases and is gradually compressed, and reaches the molding pressure value.

Then the pressure is gradually reduced, and the pressed blocks fall off the holes due to elastic recovery and their own weight, and enter the crushing and sieving device. The finished product is a granular qualified product and is weighed and packaged.

The fine powder and unqualified particles from the powder feed port are re-entered into the feed port of the hoist by the return auger and mixed with fresh materials into the pre-feeding hopper to enter the next round of the process flow.

What is the instllation and debugging method of double roller granulator?

The dry roll granulator is called dry granulator because it can directly compress and granulate fermented powdery materials with a moisture content of ≤5% during the granulation process. Products can be packaged directly through organic fertilizer packaging machine equipment. It eliminates the need for drying and cooling after granulation in the traditional organic fertilizer production process. So, how to install and debug the newly purchased dry roll granulator?

The working principle of the double rolling  extursion pelletizer is to rely on external pressure to force the material to pass through the gap between two relatively rotating rollers, and forcibly compress it into a block. During the rolling process, the actual density of the material can increase by 1.5~ 3 times, so as to meet the specified particle strength requirement

Installation and debugging method of dry rolling granulator equipment

Installation: After the newly-purchased organic fertilizer dry-method roller granulator arrives at the factory, the granulator will be used as the main machine. It depends on the number of units and is installed in conjunction with the process flow chart. Find out the elevation and horizontal placement, and the machine frame There are ground corner holes, which can be installed on concrete (the amount of solid vibration is not large, and the concrete foundation is not required to be very firm).

  1. Axial alignment: It has been adjusted during installation. Generally speaking, the possibility of adjustment is unlikely. When adjustment is required, tighten or loosen the glands on both sides of the passive bearing seat, thereby pushing the displacement of the eccentric sleeve and the active shaft roller Corresponding.
  2. Press roll gap adjustment: Sometimes it is necessary to increase the output or increase the bite angle during production. At this time, the distance between the two press shafts can be increased, and the distance between the driving shaft roller and the driven shaft can be increased. The steps are as follows : Stop, remove the upper frame of the two bearing seats, adjust the adjustment plate between the two bearing seats to the required thickness. The two rollers cannot collide between the rollers, and the minimum should be kept between 0.3-1mm.
  3. Alignment adjustment of the ball socket: The ball socket of the organic fertilizer dry roll granulator is formed by the concave socket on the main roller surface, so there are problems of axial alignment and circumferential alignment.
  4. Axial alignment steps: loosen the 6 connecting bolts of the driven gear and the adjusting sleeve, so that the adjusting sleeve and the driven gear are slightly disengaged, because the design has considered a ball and socket adjustment, and is equipped with two adjustments Bolt, so the dislocation can be adjusted regardless of the dislocation. Because the ball socket is too small, a carton board is placed between the two rollers during adjustment. After rolling, it can be seen whether the adjustment has achieved the purpose. After alignment, 8 connecting bolts can be tightened.
