With the in-depth promotion of green environmental protection concepts in the agricultural field and the increasingly prominent problem of agricultural waste treatment, organic composting equipment, as an effective way of waste treatment and resource utilization, has gradually become an important fertilizer equipment in agricultural production.       How to get high quality organic fertilizer To obtain high-quality organic fertilizer, composting equipment plays an important role in organic fertilizer production. Choose appropriate raw materials : High-quality organic fertilizer raw materials are a mixture of various organic wastes, such as kitchen waste, agricultural waste, poultry and livestock manure, etc. Diversified raw materials help to provide fertilizers with rich nutrients and microbial communities, and promote the fermentation process of composting. Maintain appropriate humidity and aeration : During the composting process, maintaining appropriate humidity and aeration is essential for the decomposition of organic matter and microbial activity. Reasonably control the moisture content of the pile and ensure that the pile has sufficient oxygen supply through the ventilation system in the composting equipment. Control the temperature of the pile : Monitoring and controlling the temperature of the pile through composting equipment is one of the key factors in producing high-quality organic fertilizer. During the composting process, as the microorganisms decompose, the pile will generate heat, and it is necessary to turn the pile and ventilate in time to ensure that the temperature of the pile remains within a suitable range, generally between 50℃-65℃. Turn the pile at the right time : Regular turning of the pile is an effective way to promote compost fermentation. This process can be completed more efficiently through fertilizer composting equipment. Turning the compost helps accelerate the decomposition of organic matter and improve the maturity and nutrient content of organic fertilizer. Control the fermentation time : The quality of organic fertilizer is closely related to the fermentation time. Generally speaking, fully fermented organic fertilizer is more stable and richer in nutrients. Through fertilizer composting equipment, the efficiency of fermentation can be improved, and the fermentation time can be controlled to ensure the production of high-quality organic fertilizer. Through scientific management and reasonable operation of fertilizer composting equipment, high-quality organic fertilizer products can be obtained, which can provide nutrients for crops, promote soil improvement, and achieve the goal of ecological recycling.       Commercial compost turner Commercial composter is a kind of equipment specially used for converting organic waste into organic fertilizer. Common composting equipments are: Crawler compost turner : can be flexibly driven to the composting area. Wheel compost turner : a large compost turning equipment. Horizontal fermentation tank : harmless treatment can be completed in 10 hours.   For more composting equipment models, you are welcome to contact us!    

With the arrival of winter, the problem of road icing is becoming increasingly apparent. In order to ensure driving safety, deicing agents are widely used. Then, how to save time and effort to produce high-quality deicing agent particles has become a widely concerned issue.       Snow melting agent granulator The deicing agent granulator, also known as the roller extrusion granulator, adopts a dry granulation process. The extrusion force between the rollers is used to press the raw materials into particles to form a granular product of the desired shape and size. Industrial salt has been widely used in deicing agents, and its effectiveness and environmental protection have been recognized by everyone. However, when traditional industrial salt is spread on the road, there are problems such as uneven particle size and fast weathering speed, which limits the snow melting effect. With the introduction of the roller extrusion granulator, these problems have been effectively solved. The industrial salt deicing agent granulator can accurately extrude and granulate it to make it a uniform and stable granular deicing agent. After this granular deicing agent is spread on the road, it can cover the surface of ice and snow more evenly, improve the speed and effect of snow melting, and ensure the safety and smoothness of road traffic. In addition, the industrial salt deicing agent granulator also has the advantages of high production efficiency and easy operation. Its environmentally friendly and energy-saving granulation process also meets the sustainable development requirements of modern industry.       Snow melting agent granulator working process The snow-melting agent roller extrusion granulator usually consists of a feeding device and two parallel and relatively rotating rollers. The powder is continuously and evenly added from the hopper to the top of the two rollers. Under the action of the continuous rotation of the extrusion rollers, the powder is squeezed into granular sheets. Then it falls to the bottom of the granulator and is broken into separate granular materials by the shaping wheel with teeth and claws, and discharged from the discharge port.   The shape and size of the snow-melting agent particles can be changed by adjusting the granulator parameters and replacing the rollers.

Screening machine is one of the important equipment to improve the quality of fertilizers. It is mainly used for screening of raw materials and screening and separation of finished products.   Screening and processing of raw materials Before the raw materials enter the granulation system, the particle size varies greatly, which will have a great impact on the ball formation rate and homogenization degree. In order to ensure that the nutrients of the finished fertilizer are uniform, the particle size is appropriate, and the formation rate is high, the raw materials will be crushed and crushed during the production process. Usually, mixed fertilizer particles require that all raw materials are less than 0.55mm. Bulk blended fertilizer plants require fertilizer particle sizes to vary greatly, generally between 1 and 3.35mm depending on different situations. The production of encapsulated fertilizers requires that instant granular fertilizers (such as urea, ammonium nitrate, potash fertilizers, etc.) are uniform particles, and the particle size of various raw materials used in the encapsulation layer is less than 0.18mm. The processing methods are also different for different fertilizer materials.     Before sieving VS After sieving     Screening and separation of finished products After granulation, drying, and cooling, semi-finished compound fertilizers cannot be packaged directly. First, the particle size caused by different granulation equipment is different. Second, the granulated products will be damaged to varying degrees during the drying and cooling process. Therefore, the particle size of semi-finished compound fertilizers is very uneven and does not meet the requirements of 1~4.75mm particle size of finished fertilizers. With the changes in the market, people have also put forward higher requirements for the uniformity of finished product particles. Through the screening machine, fertilizer particle size 2~3mm and 3~4.5mm screening can be achieved.     Application of screening machine in production line   Types of screening equipment In fertilizer production, commonly used screening machines mainly include two types: drum screening machines and vibrating screening machines. Drum screening machine: A drum screening machine is a kind of working principle that adopts rotary screening. Through the rotating motion of the drum, the raw materials are screened and graded on the screen. Larger particles are discharged from the screen holes under the action of centrifugal force, and fine particles enter the aggregate port below through the screen. The drum screening machine is suitable for various granular materials and has the characteristics of high screening efficiency, simple operation and easy maintenance. Vibrating screening machine: The vibrating screening machine uses the raw materials of vibration screening to perform multi-layer screening of materials. The vibration motor generates vibration force, so that the screen body moves under the action of vibration, thereby realizing the screening and grading of raw materials. It has the advantages of high efficiency, less blockage of screen holes, large processing capacity and low noise.     Drum Screening Machine   Vibrating screening machine

Water-soluble fertilizer is a fertilizer that can be quickly dissolved in water and can provide essential nutrients for plants. Its raw materials mainly include various nutrient elements such as nitrogen, phosphorus, potassium, and trace elements. As a new type of fertilizer, water-soluble fertilizer usually uses granulators and water-soluble fertilizer production lines to achieve production and manufacturing during the production process.   Double Roll Extrusion Granulator​ Considering the characteristics of water-soluble fertilizer being easily soluble in water, we recommend using a dry granulation process to produce water-soluble fertilizer granules. Double-roll extrusion granulator is a common granulation equipment, suitable for granulation processing of various powdered or block raw materials, including water-soluble fertilizer granule production.   The production process of making water-soluble fertilizer granules 1. Raw material preparation: Use a weighing batching machine to mix the water-soluble fertilizer raw materials and auxiliary materials in a certain proportion to ensure that the content of various elements meets the requirements. 2. Pretreatment: The well-proportioned raw materials are reprocessed by a crusher or mixer to make the particles more delicate and uniform, which is conducive to the subsequent granulation work. 3. Granulation: The processed raw materials are granulated by a roller extrusion granulator, and the ball formation rate is as high as 95%. 4. Screening and packaging: The granulated water-soluble fertilizer particles are screened to remove unqualified particles, and then packaged and stored. It should be noted that the particle size of the water-soluble fertilizer can be adjusted according to the parameters of the roller extrusion granulator to achieve the ideal particle quality.   As a highly efficient and environmentally friendly form of fertilizer, water-soluble fertilizer plays an important role in agricultural production. It can help farmers and producers increase yields, improve quality, and achieve the goals of sustainable development and green agricultural production.

Organic compound fertilizer granulation is an important process in the dry powder granulation process. Bulk fertilizer raw materials can be made into granules, making the fertilizer easy to apply, transport, and store, thereby improving fertilizer utilization and fertilizer quality. In addition to producing organic fertilizer, compound fertilizer, and inorganic fertilizer, fertilizer granulators can also be used to produce controlled-release fertilizer and slow-release fertilizer granules. Provide convenient, efficient, and environmentally friendly fertilizer processing solutions for agriculture.   Equipment Structure Disc granulator: The disc granulator is composed of a main machine, a turntable, a rotating seat, and other components. The material enters through the feed port, and then the rotating turntable scatters the material on the turntable. During the process, the turntable forms particles of the material through centrifugal force and friction. Rotary drum granulator: The main component of the rotary drum granulator is the drum. The material enters the drum through the feed port and gradually forms fertilizer particles while rolling and throwing inside the drum.   Granulation Principle Disc granulator: A disc granulator is a granulator that installs a disc obliquely on the central axis located in the center of the disc, and the central axis is supported on the bearing of the frame and is driven to rotate by a transmission device. The gravity and centrifugal force generated by the disc during rotation cause the small particle group to roll toward the lower edge of the disc and continuously adhere to the powder, gradually forming a spherical particle material. After multiple cycles, the particles are from large to small, and the particles that reach the finished particle size overflow from the edge of the disc. Rotary Drum granulator: The drum granulator adopts steam heating, and has a special rubber lining inside, which has good anti-sticking properties. The material enters the drum through the feed port and gradually forms round fertilizer particles while rolling and throwing inside the drum. The formed granules are discharged from the discharge port to complete the granulation process. The finished particles need to be further dried to increase the hardness of the fertilizer granules.   There are some differences and characteristics between disc granulators and rotary drum granulators in working principle, granulation effect, application scope, and equipment structure. You can choose the appropriate granulation equipment according to factors such as raw material moisture content, production capacity, cost budget, etc.
