fertilizer screening machine - Model 86-371-6894-4555 - fertilizer screening machine

Fertilizer screening machine is an important processing part of NPK fertilizer production line. It has simple structure, convenient use and maintenance, convenient replacement of screen drum, small dust and long service life. Pay attention to operation specifications when using screening machine.
 
1.Operation of rotary drum screener.
Before starting the screen, check whether the spindle of the screen is flexible, whether the lubrication is good, and whether the connecting parts such as bolts are firm. If there is a dust removal device in the screening machine, the dust removal device should be activated first, and then the screening machine should be started. Only when the operation is normal, can uniform feeding be allowed to the screen surface. The sequence of screening machine shutdown is the opposite.
 
2.Maintain of rotary drum screener.
During the operation of the screen, the wear condition should be checked regularly to see whether there is leakage due to the local wear of the screen surface, and whether there is excessive wear or deformation of the screen hole on the screen surface, which will affect the classification accuracy and screening efficiency of the material. In case of the above situation, the machine should be stopped to repair and replace the parts with excessive wear and tear. When the screen is running, the bearing of the screen must keep good lubrication. Under normal conditions, butter can be injected with an oil gun every week or so. Every two months or so, the bearing cover should be removed to clean the bearings and re-inject clean butter. We should pay close attention to the temperature of bearings. Generally, the temperature of bearings should not exceed 40 ℃ and the maximum should not exceed 60 ℃. To pay attention to the screening machine whether there is strong noise, screen box vibration is stable, if the screen box shaking phenomenon, should check whether the support or suspension spring is broken.
3.Overhaul of fertilizer screening machine. 
Of all the parts of the screen, the screen surface is the most vulnerable to wear, followed by the transmission belt, springs and bearings, which must be regularly repaired and replaced. It is strictly forbidden to knock with a big hammer when the screen and transmission are dismantled to prevent parts from being damaged. Parts should be kept clean before assembly. The repairing of parts and components of screening machine is different according to its structure and working conditions. Generally, no overhaul is carried out within two years, only worn parts are replaced.
 
Screening machine has a lot of functions in fertilizer processing. It can be used directly after the composted organic fertilizer is treated by the windrow turner. Rotary screening machine is also used for the finishing of fertilizer particles.

Flat die pellet mill is a kind of fertilizer granulator commonly used in organic fertilizer plant. Organic fertilizer usually needs to be granulated. This is because the compost after fermentation is mostly in the form of coarse powder or irregular small pieces, with certain moisture content and impurities, which is inconvenient to use, inconvenient to transport, and easy to cause dust pollution in the production and transportation process.
 
Raw materials for organic fertilizer production
The raw materials of organic fertilizer come from a wide range of sources: livestock manure, crop straw, rice husk, mushroom residue, furfural, distiller's grains, sugar residue, weathered coal, seaweed, sludge, biogas, peat, silkworm sand, etc. But most of the organic fertilizer plants use livestock manure and crop straw as the main raw materials. In the production of organic fertilizer granulation, the flat mold pellet mill has a good effect on straw granulation.
 
Working principle of flat die pellet mill
The main motor of the flat die pelleting machine transmits the power to the horizontal shaft through the reducer, and the power is transmitted to the vertical shaft through the bevel gear mesh, which drives the flat die or the press roll to rotate, so that the press roll and the ring die rotate relatively. The press roll of pelletizer can be used as power input, and it can rotate around the self axis, which is conducive to extruding the powder into the flat die. The cutter under the flat die rotates at a low speed to cut the cylindrical strip into the required particle length.
Function of flat die pellet mill
The flat mold pelleting machine is beneficial to the granulation of crude fiber in the production of organic fertilizer, such as sawdust, rice husk, weeds, etc. Because the flat die pellet mill is granulated at room temperature, the drying and cooling system can also be omitted in the organic fertilizer production equipment, and the energy consumption of organic fertilizer production by this process is low. In the process of pelletizing, the pelletizer has a good effect on the preservation of various nutrients and microorganisms in the raw materials, so it can also be used for low-temperature pelletizing of biological bacterial fertilizer, organic fertilizer, compound fertilizer, etc. Because the granules processed by the flat die pelleting machine are cylindrical, a ball shaping machine is also equipped in the flat die pellet organic fertilizer production line to grind irregular particles into a spherical shape for easy storage.
