Straw Crushing Production Line

Comprehensive utilization of strawStraw Crushing Production LineThis is the core process for the efficient crushing and processing of straw, aimed at realizing the resource utilization of straw, reducing burning pollution, and enhancing economic value. Below is a detailed introduction to this production line:

I. Production Line Composition

1. Pre-treatment equipment

• Conveyor systemConveyor belts or spiral conveyors evenly deliver straw raw materials into the production line.

• Decontamination equipmentMagnetic separators, vibration screens, etc., to remove metals, stones, and other impurities from straw, protecting subsequent equipment.

• Hammer mill shredderThrough high-speed rotation of the hammer blades, straw is crushed into particles of 1-10mm (adjustable).

• Chop grass machineSuitable for coarse crushing, cutting straw into sections of 3-5cm (commonly used for feedstock or bedding material).

• Dual-shaft shredderProcess high humidity or tough straw, pre-crushing before fine grinding.

• Packaging machineThe shredded straw is compressed into high-density bales for easy transportation and storage.

• Pellet/Compaction MachineFurther processed into biomass fuel pellets or feed pellets.

• Dust Removal SystemTornado separator + bag dust collector, to reduce dust pollution.

• Automated ControlPLC system accomplishes the automation of material feeding, crushing, and discharge operations.

II. Production Process

1. Raw Material Collection
   Straw from the fields is collected by a baling machine and transported to the processing site.

2. Pre-treatment
   Remove impurities with cleaning equipment; for straw with high humidity, it requires drying or drying to achieve moisture content ≤15%.

3. Crushing Processing
   Straw is conveyed into the shredder via a conveyor belt, with the particle size adjusted according to the application (finer for feed, slightly coarser for fuel).

4. Molding and Packaging
   The chopped straw can be directly packed or processed into fuel blocks/pellets through a compactor.

5. Dust Removal and Storage
   The dust collection system gathers dust, with finished products stored in a dry warehouse to prevent dampness.

Section 3: Application Scenarios

1. FeedstockCrushed for cattle and sheep feed, microbial fermentation is required to enhance nutritional value.

2. Fertilizer conversionBlend animal and poultry feces with compost to produce organic fertilizer.

3. Energy chemistryProcessed into biomass fuel for power generation or heating.

4. Base materialUsed as substrate for edible fungi cultivation or seedling propagation.

5. IndustrializedManufactures pulp, boards, straw charcoal, etc.

4. Key Points for Equipment Selection

1. Material characteristicsSelect the appropriate shredder model based on the type of straw (e.g., corn, wheat, rice).

2. Processing capacitySmall-scale production lines (1-3 tons/hour) are suitable for farmers, while large-scale ones (5-10 tons/hour) are ideal for enterprises.

3. Finished Product RequirementsFeed must be finely ground (≤3mm), and fuel pellets must be compressed into shape.

4. Energy consumption and environmental protectionPrefer low-power consumption equipment with a dust removal and noise reduction system.

V. Technical Advantages

• High-efficiency energy-savingAutomated design reduces labor costs, with an approximate electricity consumption of 30-50 degrees per ton.

• AdaptableCapable of handling straw of various humidity and lengths with low failure rate.

• Environmental ComplianceDust emissions ≤ 20 mg/m³, in compliance with national environmental protection standards.

•
