The area for composting can be calculated by the formula: composting area= hourly output* working hours*fermentation period/the density of materials/height of compost pile or depth of stacked manure. If you just want to make horse manure compost, works will be over here. In terms of commercial horse manure fertilizer production, you should make a workshop nearby fermentation area to place horse manure treatment machines.You can make horse manure fertilizer powder and pellets production line or both of them. Details are as follows.

Procedures to compost horse waste

Composting is the first and most important step during making horse manure fertilizer production. For quality and successful compost, you should do:

1.Preparation materials

For fresh horse manure, you need to adjust its moisture to 50% to 60% by solid liquid manure separator. In addition, you can add some auxiliary materials for adjust moisture, C/N ratio and improve ventilation of compost pile, such as bedding, straw powder, sawdust, rice hull powder and so on.

2.Pile horse manure up in proper size

After preparing materials, you need to mix them evenly and pile them up in long rows or place them in fermentation grooves. The former method needs large space and flat ground. And the latter needs you to build fermentation grooves, which consists of three walls.

3.Regularly turn the materials

Composting is a biological decomposition process. Microorganisms will convert organic matters into nutrients by assuming oxygen and moisture. At the same time, large amount of heat will produce, which may inhibit microorganism activity and even kill useful bacteria. The regular turning of compost pile can provide enough oxygen for fermentation, adjust temperature and blend materials in all parts evenly. That is to say, the turning of compost pile will provide favorable conditions for fermentation, so as to accelerate composting period and improve compost quality. When the composting finishes, the volume of compost pile will reduce, original odor will disappear and the horse manure will become loose and black. Then, you can use it as soil amendment and fertilizer for plants.

When the fermentation finishes, you can get quality horse manure compost from the discharge port. After several days’ stabilization, you can use it directly to soil and plants or for commercial organic fertilizer production.

How to make compost fertilizer production from horse manure?

Horse manure compost fertilizer production is an easy way to make commercial organic fertilizer. In terms of low cost and easy operation, compost fertilizer production line is a popular choice for small horse farm or small organic fertilizer factory. The detailed steps and necessary machines include:

1.Crushing horse manure compost with new type vertical crusher: Crushing process is used for deal with caking or bulks in horse manure compost, so as to guarantee uniformity of fertilizer. SEEC vertical crusher adopts blades and chains to crush caking into small particles.

2.Screening compost with rotary screen machine: Screening process is used for further making uniform compost powder. Rotary screen machine can be designed with two or more screening levels, which can make more uniform and pure fertilizer compost.

3.Making bagged compost fertilizer with powdery fertilizer packing machine: It can automatically finish feeding, filling and sewing, so as to save time and workforce.

Procedures and machines for making commercial horse manure fertilizer pellets

In addition to horse manure fertilizer powder, you can also produce horse manure fertilizer pellets. Since the fertilizer pellets are convenient for transportation, storage and application, its production process is more complex and stricter.

Multiple fertilizer pellets making machines for you to choose

We will introduce all machines that may be adopted here, and you can choose and combine different machines for production. All of these machines play different roles in the fertilizer pellets production. And they are suitable for dealing with other manures, such as chicken manure fertilizer making, goat manure compost fertilizer production and so on.

Compost crusher and screening machine

After long-term stack, there must be bulk or caking in the compost pile. Compost crusher is designed for eliminating caking and produce fine and uniform compost. The crushing device inside the compost crusher can well crushed horse manure compost into small particles. There is new type vertical crusher, semi-wet material crusher and hammer crusher (for large scale production) for you to choose. Because granulating process has higher requirements on the uniformity of compost, you had better adopt screening machine to select out smaller or larger compost particles. SEEC rotary screen machine have two or more screening levels, which can meet your different requirements on size of compost powder. In addition, screening machine can also be used after granulating, which can select out unqualified fertilizer pellets.

SEEC advice for you to make own organic fertilizer plant from horse manure

If you want to build a horse manure fertilizer plant on your farm, or you just a beginner in organic fertilizer industry, we can give you some professional instruction and advice on building organic fertilizer plant. And we will analyze this problem from the following two aspects.

What should you prepare before making fertilizer plant?

  • Raw material: It is the first factor that needs your special attention. If you breed horse, you can collect horse manure from your own farm. By building a horse manure fertilizer plant, you not only find a good way to deal with horse manure and barn bedding, but also get extra income. If you do not have direct raw material source, you should collect it from nearby places to save cost.
  • Site for building fertilizer plant: For house farm, you can build the fermentation site and production line on the farm. Or you should build a plant that close to raw materials source. In addition, the ground for building fertilizer plant should be flat and concrete.
  • Selection of fertilizer making machines according to requirements on final fertilizer product: The final product and its output decide the selection and preparation of fertilizer production equipment.

Note: If you do not know how to calculate the area of fertilizer plant and the preparation of fertilizer making equipment, you can tell us your conditions and requirements to us. And our engineer will provide you a detailed production design.

Starting an organic fertilizer plant from small scale manure fertilizer production line

For horse farm and beginner, we recommend small scale compost fertilizer production line. On the one hand, the circle of production is short and efficient (composting—crushing—screening —packing), and it occupy less space. On the other hand, the investment of small-scale production line is low and the application is wide. You can produce commercial fertilizer from all decomposed organic waste available in short time with low cost. Finally, you can directly sell them in nearby places, which is convenient for transportation and application. In a word, small scale compost fertilizer production will be your first choice to start organic fertilizer plant. This method is also suitable for fertilizer production from other organic wastes.
