How the Large Wheel Compost Turner Works

In scenarios involving large-scale organic fertilizer production and livestock manure treatment, the large wheel compost turner has emerged as a pivotal piece of equipment for facilitating the maturation and fermentation of organic waste, thanks to its advantages of wide span and high efficiency. Through scientific structural design and precise operational logic, it automates and scales up the traditionally laborious task of manual windrow turning—thereby simultaneously boosting efficiency and guaranteeing fermentation quality. The working principles underpinning this machine are a testament to sophisticated technical ingenuity.

The operation of the large wheel compost turner relies on the synergistic interplay of its core components, which primarily consist of the turning disc, transmission system, locomotion mechanism, and control system. The turning disc—the machine's central component—is fitted with multiple layers of radially arranged blades or paddles. Driven by an electric motor coupled with a speed reducer, it is capable of high-speed rotation ranging from 200 to 400 revolutions per minute, serving as the dynamic core of the turning operation. The locomotion mechanism, available in either rail-mounted or crawler-track configurations, enables the equipment to move agilely and cover the entire fermentation area. Finally, the control system facilitates both manual and automated operation, allowing for the precise adjustment of the disc's rotational speed, turning depth, and travel speed.

The operational process is clear, orderly, and can be broken down into three key stages. The first is the preparation phase, during which the operator utilizes the control system to configure the turning parameters, adjusting the depth and frequency based on the specific characteristics of the material and the ambient temperature—for instance, increasing the turning frequency during cold seasons or scheduling operations for early morning and late evening during hot seasons. Next comes the core turning phase: once the equipment is activated, the turning disc slowly descends into the material pile. The rapidly rotating blades rake up and pulverize the material at the base of the pile; subsequently, centrifugal force hurls the material into the air, ensuring a thorough mixing of the deep-layer material with the surface-layer material while simultaneously driving air deep into the pile's interior to provide ample oxygen for microbial fermentation.

The final stage involves continuous operation and adjustment. The locomotion mechanism propels the equipment forward at a steady pace while the turning disc continues its work, ensuring the uniform turning and aeration of material across the entire area. Concurrently, this process shifts the position of the windrow, thereby clearing space for the addition of fresh material. Throughout the operation, sensors continuously monitor the pile's internal temperature and moisture levels; the control system automatically adjusts the height and rotational speed of the turning disc to prevent excessive heat from killing beneficial microorganisms, thereby ensuring a stable and highly efficient fermentation process. 

This mode of operation not only significantly boosts operational efficiency—with a single unit capable of processing hundreds of cubic meters of material per hour—but also shortens the fermentation cycle, reducing a process that originally took 25 days to approximately 18 days. By transforming organic waste—such as livestock and poultry manure and crop straw—into high-quality organic fertilizer, it simultaneously resolves environmental pollution issues and facilitates resource recycling, thereby becoming an indispensable "powerful assistant" in the fields of modern ecological agriculture and the environmental protection industry.

Cake and meal materials are a type of nutrient rich organic fertilizer granulation raw material

图片
  Cake and meal materials are a type of nutrient rich organic fertilizer granulation raw material that plays an important role in improving the quality of organic fertilizers. Bean cake is one of the most common raw materials for cake and meal. The soybean cake left after pressing and extracting oil contains a large amount of protein, amino acids, as well as nutrients such as nitrogen, phosphorus, and potassium. These rich nutrients make soybean cake a high-quality raw material for organic fertilizers. After fermentation treatment, the high molecular weight organic matter in soybean cake is decomposed into small molecules, which are more easily absorbed and utilized by crops. Using an  organic fertilizer granulator  to turn fermented soybean cake into granular fertilizer can accurately control the nutrient content and release rate of the fertilizer, providing comprehensive and lasting nutritional support for crop growth. Rapeseed cake also has high nutritional value. It c...

How to use a disc granulator to process fertilizers in a fertilizer production line

图片
  In the fertilizer production line, the   disc granulator   is like a skilled "shaper", endowing fertilizers with ideal shapes. After various fertilizer ingredients are mixed according to precise formulas, they enter the  disc granulator . The machine starts and the disc begins to slowly rotate. Under the clever action of centrifugal force, frictional force, and gravity, materials gradually gather at the edge of the disc. At first, these materials were just a loose collection, but as the disk continued to rotate, the materials kept rolling, and newly added materials continued to adhere to existing small particles, like rolling snowballs, gradually growing and forming. The fertilizer particles produced by the  disc granulator  have regular shapes, mostly round spherical shapes. This perfect spherical particle has obvious advantages in the fertilization process, as it can be more evenly dispersed in the soil, ensuring a more balanced absorption of nutrients ...

Specific processing flow of fermentation equipment in organic fertilizer production line

图片
  With the continuous development of China's economy, organic fertilizers have gradually become popular among farmers and are an indispensable part of the development of the organic green industry. Of course, they are also more in line with the current national policy guidance. Therefore, the quality of   organic fertilizer production equipment   is also the top priority of development needs. It not only allows organic fertilizer processing enterprises to make better profits, but also brings more practical and efficient commodity organic fertilizers to farmers. Chicken manure is a very good raw material for organic fertilizers. The production of organic fertilizers using chicken manure is mainly divided into two parts: pre fermentation and post processing. The pre fermentation part is a necessary processing step for any form of organic fertilizer, and a fermentation tipping machine is needed to assist in the processing process. The later processing process mainly selects ...
