Simple Turning Machine

Maintenance and Care Methods

1. Per-Shift Maintenance:

Check fasteners and bearing clearances.

Add grease to bearing housings and check the gearbox oil level.

Clean up any residual material from the machine and work area.

2. Weekly Maintenance and Periodic Inspection:

Check the contactors in the electrical control cabinet for damage.

Check the motor and gearbox for overheating and abnormal noises; replace severely worn bearings promptly.

3. Oiling Standards:

The cycloidal pinwheel gearbox must have its oil changed after the first 200 hours of operation, and thereafter every six months or one year (using No. 50 machine oil or hypoid gear oil).

Common Equipment Problems and Solutions

Based on experience with common equipment malfunctions and troubleshooting, the main problems are as follows:

Application of Equipment in Organic Fertilizer Production Lines

The trough-type compost turner is the only core equipment in the fermentation section of an organic fertilizer production line. The entire organic fertilizer production line is divided into a raw material pretreatment section, a trough-type aerobic fermentation section, and a post-treatment granulation section. The compost turner connects these stages:

1. Upstream Support: After crushing and mixing with a batching mixer to adjust the carbon-nitrogen ratio and moisture content, the raw materials are transported to the fermentation tank, where the compost turner completes the composting process in about 20 days.

2. Core Fermentation Section: The compost turner repeatedly turns and tosses the compost, completing the harmless treatment and stabilization of the organic materials, and killing insect eggs, pathogens, and weed seeds inside the compost pile.

3. Downstream Support: The fully composted organic raw materials are transported to a crusher and a drum screener. After screening, they are divided into powdered organic fertilizer products for direct packaging. If granulated organic fertilizer is required, the material is sent to the granulation section for further processing.

Fermentation Process of the Equipment

The trough-type compost turner serves the trough-type aerobic composting fermentation process.

1. Aerobic Fermentation Principle

Trough composting is a composting process in which materials are placed in a fermentation trough, and then turned, stirred, and crushed by a trough-type compost turner, allowing the materials to ferment, mature, and degrade. When the turner's drum rotates at high speed, the blades crush and mix the materials, while simultaneously turning and loosening them by the drum.

2. Fermentation Tank Structure

A fermentation trough is formed by building two walls on flat ground, creating one or more fermentation troughs. The trough-type compost turner moves along a track on the fermentation trough. The turner is moved from one fermentation trough to another using a transfer vehicle.

3. Feeding and Discharging Methods

Batch Feeding: A batch of material is fed into the fermentation tank at one end, and then moved to the other end through turning and tossing. Feeding is then repeated at the beginning, continuing until the fermentation cycle ends, at which point the finished product is discharged from the other end.

Bulk Feeding: The entire fermentation tank is filled with material at once, and discharged all at once at the end of the fermentation cycle.

4. Core Functions of Fermentation Process

Stirring and Conditioning: Adjusts the carbon-nitrogen ratio, pH, and moisture content of the raw materials.

Temperature Control: Creates alternating medium and high temperatures to promote the growth of beneficial microorganisms.

Improved Permeability: Transforms viscous, dense materials into loose clumps.

Moisture Adjustment: Forces moisture evaporation, reducing the moisture content from approximately 55% initially to below 20% in the finished product.

5. Fermentation Cycle

The fermentation cycle of the trough-type compost turner is typically around 15 days. Utilizing special aerobic fermentation technology, organic waste can be rapidly decomposed, dehydrated, sterilized, and deodorized, achieving the goals of harmlessness, resource recovery, and volume reduction.

6. Fermentation effect: Compared with static composting, the fermentation tank mode is easier to obtain stable product properties, has a better odor control effect, a higher degree of overall automation, and saves space.

Safety Operating Procedures

1. Operators must not operate the compost turner after consuming alcohol, or when feeling unwell or unwell.

2. For safety, all tracks of the compost turner must be grounded.

3. Power must be disconnected before replacing cable trays or cables.

4. No one may pass in front of or behind the compost turner during production.

5. No maintenance or lubrication is permitted during production.

6. The turner must be operated at the specified speed; exceeding the speed limit is prohibited.

7. Unauthorized personnel are prohibited from operating the machine.

8. When raising or lowering the winch, prevent the drum from being lowered too low and damaging the blades, and prevent over-extension, which could damage the winch shaft and bearing housing.

9. Replace the winch wire rope immediately if it has fuzz or more than 7 broken strands.

The trough type compost turner has the characteristics of high efficiency, smooth operation, durability and uniform turning. Its control cabinet can realize manual or automatic control and adapt to the needs of different automation levels. For users who want to achieve industrialized harmless treatment and improve the quality of organic fertilizer, it is currently a mainstream and cost-effective choice.
