The Synergistic Logic of Chain Plate Turning, Sealed Fermentation and Wet Granulation

A complete organic fertilizer production line comprises three core process stages: compost turning fermentation, sealed precision fermentation, and wet granule formation. Each stage serves a different process function, and equipment selection and stage integration determine the overall production line efficiency and finished product quality.

Chain Plate Compost Turner performs initial aerobic fermentation. After organic waste (livestock manure, agricultural residues, kitchen waste) enters the fermentation tank, the chain plate turner mixes, loosens, and aerates the material through a continuous turning system, balancing moisture, temperature, and oxygen distribution within the pile. The manganese steel chain plate's high wear resistance and load capacity ensure stable equipment operation under high-density material conditions, with processing capacity reaching 6400m³/H. During the 15-20 day composting cycle, the turning stage creates a stable fermentation environment for aerobic microorganisms, accelerating organic matter decomposition and ensuring compost quality uniformity.

304SS Fermentation Tank performs precision temperature-controlled fermentation. Material from pre-fermentation turning enters the sealed fermentation tank. The 304 stainless steel fully sealed structure eliminates odor leakage, the jacketed cooling system precisely regulates internal temperature, and the automatic aeration system continuously supplies oxygen to maintain aerobic microbial activity. The PLC intelligent control system with touch-screen interface enables automatic monitoring and adjustment of temperature, oxygen, and fermentation time, upgrading fermentation management from experience-driven to data-driven. The 380V/415V dual voltage configuration adapts to different regional grid standards.

Disc Granulator performs granule formation. Fermented powder material enters the disc granulator, where the wet granulation process uses centrifugal force, friction, and spraying liquid to roll and bond powder materials into round granules with uniform size within the inclined rotating disc. Disc angle and rotation speed are adjustable, adapting to different raw material characteristics and capacity requirements. The 4kW/5.5kW motor options cover the capacity gradient from small to medium-large scale.

The synergy efficiency of the three-stage process depends on raw material state consistency between stages. The material uniformity output by the chain plate turner directly affects the sealed fermentation tank's fermentation efficiency — uniform material state enables more balanced temperature and oxygen distribution within the tank, improving PLC temperature control precision. The fermentation quality consistency output by the fermentation tank determines the granulation stage's granule formation rate and particle size distribution — quality-stable fermented material makes material behavior within the granulation disc more predictable, improving finished granule consistency.

Equipment selection for the three-stage process must match capacity tiers. The chain plate turner's 6400m³/H processing capacity suits large-scale commercial composting projects; the sealed fermentation tank volume is customizable to match project throughput; the disc granulator's 4kW/5.5kW motor and customizable disc diameter adapt to different capacity requirements. Capacity matching across all three stages prevents any single stage from becoming a production line bottleneck.
