fertilizer granulator Jan 4, 2023

Compost turning machine is a necessary equipment in the production process of organic fertilizer. Its main function is to automatically turning the raw materials in the fermentation, so that the materials can better contact with the air, so as to improve the speed of material fermentation. On the other hand, it also plays a role in controlling the composting temperature.

The main purpose of turning over fermented compost is to evaporate excess water, so that the fertilizer and air are fully mixed, and the air is wrapped in the gaps of the compost. The decomposed fertilizer is suitable for the deep processing of fertilizer granulator. The smooth realization of composting fermentation depends on the distance the fertilizer travels in the air after being thrown. To analyze the effect of fertilizer throwing, the following assumptions are made for the thrown fertilizer particles:

1) When the fertilizer particles are thrown away from the Throwing Knife, the initial velocity of their motion is equal to the absolute velocity of the throwing knife speed and the involved velocity of the tipper

2) The movement of fertilizer particles has no influence on the movement of adjacent fertilizer particles

3) The trajectory of fertilizer particles is a continuous curve.

There are many types of organic fertilizer turning and throwing equipment on the market, and the actual use functions are also very different. The main selection factors are determined according to the customer’s terrain conditions, fertilizer production line technology, investment scale and other aspects. One of the most commonly used and lowest cost compost turning equipment is the trough turning machine. The smallest size is two meters in width. Of course, the large trough turning machine can reach more than 10 meters, and the price is more than 20,000 US dollars.

In addition to the above-mentioned trough turning and polishing machines, there are many types of organic fertilizer fermentation equipment, which are divided into two categories, trough turning and turning machines and walking turning and turning machines. The walking type turning machine is divided into crawler type and wheel type.

Composting Solution of Organic Fertilizer Crusher

fertilizer granulator Dec 29, 2022

In recent two years, with the rapid development of social economy, we believe that people are more and more familiar with the organic fertilizer grinder, but we often encounter the problem of organic fertilizer composting. So how do we control these steps in this process? Now let’s see.

Water conditioning, water is necessary for microbial growth. During composting, 50-60% water (by weight) is conducive to microbial synthesis. The water content of livestock manure is 75-80%, and straw with low water content is usually used for conditioning.

The control of fermentation temperature is one of the important conditions for the normal fermentation of organic materials. In cold climate areas, heating and heat preservation measures should be taken to ensure the normal stop of fermentation process. At present, the economic and feasible method is to use solar energy to heat and heat materials. The greenhouse principle can be applied to the design of fermentation equipment. The fermentation equipment shall be made of PVC or glass fiber reinforced plastic roof materials and wall materials with good light transmission performance and durability. The fermentation equipment should be well sealed and well insulated in winter; At the same time, it shall be convenient for ventilation and provide oxygen for material fermentation.

Regulate carbon nitrogen ratio

Generally speaking, the C/N ratio of livestock manure is lower than 20:1, while that of straw is higher than 50:1. If the C/N ratio of the fermentation material is adjusted to 25-35:1, on the one hand, a part of straw can be added to livestock manure to adjust the C/N ratio, and on the other hand, the moisture content of straw is low.

Pile up

Aeration is an important factor affecting composting temperature and fermentation effect. The purpose of turning the pile is to improve the ventilation condition in the pile, distribute water, promote the propagation of high-temperature beneficial microorganisms, make the pile temperature reach 60~70 ℃, accelerate the transformation of fermentation materials, so as to achieve the purpose of average mixing, heating and decomposition. The materials can be turned over manually, or by wheeled dumpers, loaders, deep groove aerobic dumpers and other machines. In the process of fermentation, it is suitable to turn it for 1-2 times a day.

screening

In order to improve the commercial value of organic fertilizer products and facilitate packaging and storage, the screening process is usually used to separate large materials. There are many kinds of screening equipment, such as cylinder screen, vibrating screen, etc. In order to reduce investment, manual screening can also be used. The materials above the screen can be landfilled or reused as fermentation auxiliary materials, and the materials below the screen can be used as organic fertilizer products.

Aerobic dynamic composting core equipment Organic fertilizer composter

fertilizer granulator Dec 29, 2022

Organic fertilizer composter is the core equipment of aerobic dynamic composting. As a new type of machinery, it is unknown in the national product catalog, but it has rapidly multiplied in the fertilizer machinery and equipment family, becoming a tool to replace manual and forklift dumping, and is the mainstream product that affects the development trend of the composting industry. The importance of organic fertilizer composter stems from its role in composting production:

Mixing effect in raw material conditioning

In order to adjust the carbon nitrogen ratio, pH and water content of raw materials, some auxiliary materials must be added to the compost. The main raw materials and various auxiliary materials are roughly stacked together in proportion, which can be evenly mixed by the dumper to achieve the purpose of tempering.

Adjust the temperature of the raw material pile

During the operation of the stacker, the raw material particles fully contact and mix with the air, so that a large amount of fresh air can be stored in the material stack, which is conducive to the active production of fermentation heat by aerobic microorganisms and the improvement of the stack temperature; When the temperature is high, adding fresh air can reduce the chimney temperature. The state of medium temperature high temperature medium temperature high temperature alternation is formed, and various beneficial microorganisms are rapidly growing and reproducing in the temperature range suitable for beneficial microorganisms.

Improve the permeability of raw material pile

The turnover system can process the materials into small pieces, making the thick and dense raw material pile fluffy and elastic, forming appropriate pores.

Adjust the water content of the raw material pile

The suitable water content of raw material fermentation is above 55%, and the water content of finished organic fertilizer is below 20%. In the process of fermentation, new water will be produced by biochemical reaction, and the consumption of raw materials by microorganisms will cause the water to lose its carrier and become free. Therefore, the water content will decrease in time with the fertilizer making process. In addition to the evaporation caused by heat conduction, the turning of raw materials by the organic fertilizer composter will also cause forced water vapor emission.

Special requirements for composting process

For example, crushing raw materials, giving a certain shape to the raw material pile or realizing quantitative replacement of raw materials.

fertilizer granulator Dec 29, 2022

In the production of livestock manure fertilizer production line, the key equipment is the organic fertilizer turning machine. The materials and the composition of the main parts have a very important impact on the processing of livestock manure. Here is a brief introduction to the compost fermentation program of the organic fertilizer turning machine.

Fermentation scheme of organic fertilizer compost turning machine:

1. First, pile chicken manure or other animal manure, domestic waste and other fertilizer base materials on a flat ground in strips: the width of pile is equal to the width of equipment, the height is as high as possible, and the length is as long as possible, such as 100m, 50m, etc. if the site is feasible; the ground should be flat, cement, brick, and land can be used (as long as it is flat and has a certain hardness). The production of 10000 tons of fertilizer is required The area is 5-6 mu.

2. Add the piled chicken manure (other livestock manure or domestic garbage) to the biological starter (strain), 1 kg of starter (strain) per ton of fertilizer base material.

3. Use a compost turning machine to ferment straw and chicken manure (pig, cattle, sheep and other livestock manure, filter mud, sludge, domestic garbage, and other agricultural and animal husbandry organic solid waste, the water content should be 50%-70%), and fermentation Mix and stir evenly. It can be deodorized in 3-5 hours, and the temperature is increased to 50 degrees in 16 hours, and when the temperature reaches 60-65 degrees, it will be turned over again to increase oxygen. In the future, whenever the temperature in the pile reaches 60℃-65℃, the pile will be turned over to achieve the effect of uniform fermentation, aeration, and cooling, and repeat the last process until it is ripe.

4. If the water content of chicken manure is too high, you can use the method of reflux to put the last dry fertilizer on the bottom to form a strip, put the chicken manure in the middle, so that the water on the top is soaked to the bottom, and then turn.

5. Generally, it takes 7-10 days to fertilize. The decomposed compost is processed again by granulator. The fertilizer granulator machine price is low, and the machine is stable and durable.

Bucket elevator is used as the conveying equipment of organic fertilizer production line and npk blended fertilizer. How to deal with failures in the application process?

1. Aiming at the chain hook fracture problem of bucket elevator, the staff should lengthen the distance of the chain hook wire during maintenance, and add a reinforced base plate at the fixed part of the chain hook when installing the hopper, and weld the two parts together, so as to form a relatively complete chain link. This can not only reduce the occurrence of the chain hook fracture to a great extent, but also improve the safety One step to ensure the strength of the chain hook.

2. In view of the situation of the upper sprocket slipping, before NPK production line work, the relevant staff must check the situation of the sprocket of the elevator, and try to use the anti-skid sprocket as far as possible. The upper sprocket can be processed to form a chain nest shape, which can greatly reduce the occurrence of the sprocket slipping, and the transmission efficiency of the bucket elevator can also be effectively improved .

3. The bucket elevator transports the granules formed by the fertilizer granulator. In view of the situation that the materials stick to the wall in the bucket elevator shell, the shell situation must be fully considered when selecting the conveyor.

How to select appropriate equipment manufacturers for NPK fertilizer production line

fertilizer granulator Dec 29, 2022

With the development of chemical fertilizer industry, NPK fertilizer equipment industry has developed rapidly in recent years, which has driven the development of the industry to a certain extent. NPK production line has been developing steadily. At present, the technological level of the world is to promote the development of numerical control technology by production as the mainstream, and the future development will be the same.

On the basis of further improving precision, efficiency, automation, intelligence and networking, our factory has gradually transformed fertilizer equipment into processing unit and cutting-edge flexible manufacturing system. At present, the fertilizer production equipment industry has entered the stage of scientific development and technology first, China’s international influence continues to heat up, and the industrial technology level is further improved. As our products are closely linked with strategic new industries, with the advantages of high efficiency, energy saving and high cost performance, our exports to developed countries are mainly at the middle and low end, and this part of consumer demand is rigid. Therefore, there is still a large market space for the development of fertilizer equipment industry.

Facing the huge demand of agricultural development, fertilizer granulator equipment manufacturers have the responsibility to continuously develop products with better quality, lower price and more suitable for recycling. If we want to process fertilizer into high quality commercial fertilizer, we must carry out granulation.

Our granulation equipment includes disc granulator, rotary drum granulator and roller extrusion granulator. Because different organic fertilizer components are different, the organic fertilizer particles produced are different, and different soil requires different fertilizer particle size. Granulator solves this problem, and can produce organic fertilizer with different particle size and shape according to different needs.

Model Selection of Organic Fertilizer Granulator

fertilizer granulator Dec 29, 2022

The difference in the selection of organic fertilizer granulator models lies in the selection of appropriate granulation methods according to the use requirements of materials. This is just a big general term. There are subdivisions and branches under it. It is mainly divided into dry method and wet method:

Dry process mainly refers to products with relatively low water content. Generally, water content below 10% is a zero limit. (There are also few materials that can reach 16%, for example, some materials only carry crystal water.) Most of the particles produced by dry granulation are irregular particles (for example, ordinary granular potassium fertilizer) or the more common shape is similar to small gravel. With the current industrial upgrading and increasingly strict environmental protection requirements in China, many chemicals and building materials need granulation.

The main index of wet granulation is the material with a water content of more than 20%. There are various equipment and methods for wet granulation. For example, disc granulation, drum granulation and spiral granulation have been carried forward many years ago, and have been greatly improved by increasing the use environment and processing requirements of different materials. For example, the particle size of relatively popular organic fertilizers over the years ranges from 1mm to 6mm. These methods were adopted.

Compared with wet granulation, dry granulation in organic fertilizer granulator consumes less energy, is more environmentally friendly, does not require drying, does not add water and binder, and does not change the properties of materials; Compared with wet granulation, these are also several advantages of dry granulation. It is more suitable for industrial production.

In another case, some materials require relatively small particle sizes. Products between dozens of meshes and 100 meshes can also be reduced by airflow, spray and rapid drying.
