Key points for selecting metal baler models

Key Considerations (Demand Analysis)

1. Raw Material Characteristics

Metal Type: Is it thin, light scrap steel, sheet metal, can bodies (e.g., car shells, corrugated steel sheets), or heavy, heavy scrap steel, structural steel, reinforcing bars, or scrapped car parts? Different materials have vastly different densities and strengths.

Shape and Dimensions: The maximum initial dimensions (length, width, height) and thickness of the raw material; whether it is tangled.

Pre-treatment: Has it been crushed or sheared? This directly affects baling density and efficiency.

2. Output and Efficiency Requirements

Daily/Hourly Processing Capacity (tons): This is a core indicator determining the equipment scale (main cylinder pressure, bale size).

Work Schedule: Single shift, double shift, or continuous production? This affects equipment durability design and hydraulic system cooling capacity.

3. Finished Bale Requirements

Bale Size (Length x Width x Height): Must conform to the standards of downstream steel mills or transportation companies.

Bundle density (tons/cubic meter): High-density bales (typically over 2.2 tons/cubic meter for heavy-duty machines) are easier to transport and smelt, but also command higher prices.

Bundle weight: Ideal weight range for each bale.

4. Power and Supporting Facilities

Available power supply: Three-phase 380V is standard, but higher power models may require higher voltage or a transformer.

Plant conditions: Installation space (length, width, height, especially pit depth), foundation load-bearing capacity, overhead crane lifting capacity.

Hydraulic oil cooling: Water-cooled or air-cooled? Depends on local climate and workload.

Core Component Parameters

Main System Pressure (tons): The most critical parameter determining the final compression force. Higher pressure results in higher packing density.

Gate Size (Internal Cavity Dimensions): Determines the maximum size of raw materials that can be placed inside and the size of the finished bale.

Compression Chamber Dimensions: The actual size of the compressed bale; must be considered in conjunction with the goblet size.

Main Cylinder Diameter and Stroke: Affects compression force and compression speed.

Door Locking Mechanism: Must be robust and reliable to ensure safety under high pressure. Hydraulic locks are more advanced and secure than mechanical locks.

Pressure Head Structure: A separate design for "pre-compression" and "main compression" improves efficiency; volume is compressed first, then high-pressure forming occurs.

Control Method: PLC (Programmable Logic Controller) automatic control is the modern standard, more stable, intelligent, and easier to maintain than relay control.
