At present, the main organic fertilizer equipment turning are trough turners and self-propelled turners. The trough turner needs to build a fermentation tank and put the turning frame on the trough to work. The difference between the two is that the self-propelled pile turner relies on tires to walk and work. The trough turner is widely used, with low price and stable operation. The disadvantage is that it is limited by the groove type of the site. The width, depth and length of the trough must be determined in the early construction. The self-propelled stacker is not limited by the site, can walk at will, and is easy to use, but the price is slightly higher.

The trough type organic fertilizer turner is a widely used type of pile turner, including simple compost turning machine, hydraulic compost turning machine, chain plate trough type compost turners, etc. The working part of the turner adopts the motor reducer to drive the rotation of the tine of the rotary tiller, and the circular telemotion of the tine of the rotary tiller drives the material to be thrown up and down, so as to achieve the effect of turning the pile, so as to meet the requirements of the material’s moisture content and good quality. The demand of oxygen fermentation, the power used is small, the production cost is reduced, the energy is saved, the whole machine has good rigidity, balanced force, concise, strong, performance, easy to control, strong usability of the storage site, easy to use and maintain, and low price, which makes the investment The threshold is lowered.

Self-propelled dumpers such as windrow compost turning machine are mainly used for fermentation and dumping of organic wastes such as livestock and poultry manure, sludge waste, sugar mill filter mud, slag cake and straw sawdust. They are widely used in Fermentation and decomposing and water removal operations in sludge waste plants, compound fertilizer plants, organic fertilizer plants, horticultural fields, and Agaricus bisporus planting plants. It is suitable for aerobic fermentation, with high efficiency, stable operation, firmness and durability, and even turning. This type of equipment has the advantages of low investment, low consumption, fast fertilizer production, large output, no site restrictions, flexibility and freedom, and is a common equipment for converting livestock and poultry manure and organic domestic waste into high-quality bio-organic fertilizer.

Process flow and advantages of horizontal mixer for organic fertilizer ingredient processing

Organic fertilizer ingredient processing horizontal mixer is suitable for continuous mixing of mixed fertilizer powder, usually after automatic ingredient equipment. Its working principle is that the material enters the mixing tank and is evenly stirred through a set of spiral blades in the form of double spiral belts, before entering the next granulation and other processes.

Organic fertilizer ingredient processing horizontal mixer product structure composition: The single shaft continuous mixer is mainly composed of mixing shaft, mixing page, mixing chamber, motor, and reducer. 3、 Product working principle: The horizontal mixer utilizes a shaft with spiral blades installed on the root to rotate, and while conveying powder materials such as dry ash, water is added to stir. The dry ash powder materials are evenly humidified, achieving the goal of not emitting dry ash and not leaking water droplets from the humidified materials.

The advantages of a single axis continuous mixer for organic fertilizer ingredient processing and mixing equipment are:

1. It has high mixing efficiency and a small footprint. The spiral blades are made of high wear-resistant special alloys.

2. The horizontal mixer adopts a reducer transmission, which rotates smoothly and has low noise.

3. The horizontal mixer has a reasonable structure for feeding from the top and discharging from the bottom.4. The sealing between each joint surface is tight and operates smoothly.

What issues do disc granulators need to consider when granulating?

Many granulation processes begin with the pretreatment of fines with moisture. The material is first pretreated and then fed into a disc granulator, where it is collected by the rotation of the disc. Centrifugal force and gravity allow particles of different sizes to be sorted on the disc. Small particles form on one side of the disc, and as their size increases, they work towards the discharge side of the other side of the disc. Moisture and feed ingredients are added, combined with rotating discs, shocks and dense loose seeds to help them grow into smooth round pellets. Once the particles have reached the desired size, they are discharged from the disc and dried in a rotary dryer.

In the production process of organic fertilizer equipment granulation, the raw materials are required to have a certain viscosity. Some raw materials are relatively loose after fermentation and are not easy to be granulated. It is necessary to add a certain amount of water or binder to increase the viscosity of the material. The granulation method adopted by the organic fertilizer equipment disc granulator and raw meal granulator, water or binder is added during the granulation process to ensure the smooth granulation of the material.

Disc granulator operation is often considered an art that goes beyond raw material viscosity and combines many mechanical and process variables to achieve desired granule properties. The variables that must be considered during operation of the pan granulator are outlined below:

Mechanical variables:

Translation angle, translation speed, nozzles (including nozzle number, location, type, etc.)

Process variable:

Raw material characteristics (fine/coarse; sticky/non-sticky), ratio of dry to wet product, binder type, required size of finished product, raw material moisture, feed rate, binder rate, etc.

Configuration and price of organic fertilizer equipment for livestock and poultry manure

The organic fertilizer equipment for livestock and poultry manure mainly consists of a drying system, a fermentation system, a crushing system, a deodorization and dust removal system, a granulation system, a batching system, a screening system, a mixing system, and a finished product packaging system. Livestock and poultry manure must undergo decomposition with a decomposition agent before application. Parasites and their eggs, as well as infectious bacteria, present in livestock and poultry manure, are inactivated and deodorized through the process of decomposition.

The construction scale of animal manure organic fertilizer equipment configuration is generally 30-100000 tons per year. We need to comprehensively consider local resources, market capacity, and market coverage. The investment scale and product plan design need to be formulated based on the following conditions: characteristics of raw material resources, local soil conditions, local planting structure and main crop varieties, factory site conditions, production automation level, etc.

When purchasing equipment for animal manure organic fertilizer production lines, customers usually care about the price of the equipment, understand the process flow, and then determine what equipment should be equipped with their organic fertilizer production line equipment, such as a disc granulator and a wet stirring tooth granulator. The round disc granulator is cheap, and the water content after granulation is relatively high, usually around 40%, requiring a dryer for drying, And the particles produced by the stirring tooth granulator, if the scale is relatively small, can be naturally dried. Customers typically purchase 3-5 tons of small organic fertilizer production line equipment. Some farm owners consider the price and, based on their own factory’s economic strength, typically purchase around 10000 tons of small organic fertilizer production line equipment.

The organic fertilizer granulator for sludge pond sludge is designed and manufactured using a new wet continuous push rod granulation process. This machine can not only granulate various organic substances, especially coarse fiber materials that are difficult to granulate using conventional equipment, such as crop straw, wine residue, bacterial residue, pharmaceutical residue, animal manure, etc., after fermentation, they can be granulated, but also achieve good granulation effects for raw materials such as humic acid and urban sludge.

Characteristics and advantages of granulation machines for organic fertilizer production equipment in sludge ponds:

The sludge pond organic fertilizer granulator consists of a body part, a granulator rotor part, and a transmission part. The working principle is that materials enter the machine from one end of the feeding port, and are continuously pushed through the granulation rotor and mechanically moved with the machine casing to achieve the purpose of granulation. The finished particles are pushed out of the machine at the other end of the machine. The rotor is driven by the motor and reducer of the transmission device, and the transmission and body parts are mostly fixed on the same frame. This not only has a sturdy structure, smooth operation, but also is very convenient to install. It is a new era of environmentally friendly fertilizer production equipment.
