10-12 Tons/hr Cow Dung Bio-Organic Fertilizer Processing Line

Definition of cow dung biological organic fertilizer production line

The production line of cow dung organic fertilizer is a complete set of equipment which uses cow dung as raw material to process organic fertilizer.Cow manure can fluff soil, improve soil compaction and enhance soil fertility.Crops such as straw, rice bran (containing nitrogen, phosphorus, potassium) can also be used as fillers, and then used as fermentation materials with biological agents.

Raw material

The main raw material of cow manure bio-organic fertilizer is cow dung.

Cow dung can be made into high quality organic fertilizer products after fermentation.Cow dung contains 14.5% organic matter, 0.30 ~ 0.45% nitrogen, 0.15 ~ 0.25% phosphorus and 0.10 ~ 0.15% potassium.Cow dung organic manure is a cold fertilizer, the content of organic matter and nutrient is lower in all kinds of livestock, fine texture, slow decomposition, low heat, is a slow effect fertilizer, suitable for base fertilizer.

Flow Process introduction

Cow dung bio-organic fertilizer production line are cow dung mixed with straw, rice husk and other organic compounds, composting fermentation, drying after pretreatment, again into the processing workshop, through crushing, mixing, pelleting, cooling, packaging process, and made into bio-organic fertilizer. The whole line is 10 to 12 tons per hour of organic fertilizer granules, total power is about 1050 kw, the workshop covers an area of 4000 m2, contains raw material warehouse and finished product warehouse; The design of the whole line is compact, reasonable, meets the requirements of environmental protection, and can be customized according to customer requirements.

Allocated equipment includes: fermentation composer, organic fertilizer grinding machine, drum cleaning screen, drum dryer, blade hammer mill, paddle mixer, ring die pellet mill, swing cooler, package scale and other equipment.

Fermentation and compost process

A aerobic fermentation and a secondary anaerobic fermentation

A good oxygen fermentation, good stir ingredients into 1.5 meters to 2 meters wide, 0.8 meters to 1.2 meters high, length not less than three meters, pay attention to the appropriate fermentation process of oxygen and turns heaps (when temperature reaches 75 ℃ or above should be turned over several times), temperature control within 65 ℃, high temperature have an effect on nutrient.Composting for 2 days temperature raises, 3 days odorless, 7 days loose, 9 days fragrant, 10 days into fertilizer.

Second anti - itch fermentation is called after aging stage, also known as second fermentation.The materials can be decomposed after 7 days and enter the aging stage.Then it enters the pre-treatment and granulation stage in the workshop.

Compost equipment: LYLP-9, power 50.5kw, output 300 m3/h.

Pre-treatment process

That is the organic fertilizer after good fermentation was crushed, screened and dried.

The special chain type grinder for organic manure is widely used in composting of bio-organic fermentation, composting of urban household waste, grass-mud carbon, rural straw waste, industrial organic waste and composting of livestock and poultry waste.The allowable value of water content of organic fertilizer for biological fermentation was 25 to 55%, which solved the problem of high water-containing organics comminution.

The roller cleaning screen can clean the impurities in the raw materials, including big wood blocks, stones, materials, and so on, to prevent the next process of mechanical equipment, transport equipment and other failures or damage.The primary screen is characterized by high output, less power consumption, simple structure, small space, easy maintenance and easy installation.

The roller dryer is used for drying raw materials with excessive moisture, and drying the raw materials with about 20% moisture. The granulating molding of the following sections is done once. The roller dryer adopts cast steel integral structure with high strength and stable operation.The special design and reasonable layout of the feeding plate in the drum can fully mix the materials and hot air.The outer layer of the tube is insulated to prevent heat loss and improve heat utilization.

Drying equipment: LYHG3.0*18, roller diameter 3m, length 18m, power 30kw.

Grinding process

Cow dung bio-organic fertilizer in the grinding process shall deliver the dried materials to the hammer mill through the conveying equipment, which is equipped with iron removing device before the hammer mill.

Mixing and fungus adding process

Through the micro-element adding hopper, the fungus seeds and raw materials can be added to the mixing machine for mixing, after evenly mixed, enters the next section.

Single shaft paddle type mixer is suitable for high mixing uniformity and low residue organic or inorganic compound fertilizer;The mixer can be made of stainless steel, with specially designed sealing and blade arrangement.

Pelleting and bagging process

Cow dung bio-organic fertilizer is fed uniformly by the pellet mill feeding screw in the pelleting process, the pellet mill is fed continuously, the pellet is cooled by the cooler, and the finished pellet is automatically weighed, packed and transported to the warehouse.
