Proper feed preparation is essential for optimal operation of metal chip briquetting equipment. The following requirements ensure equipment longevity and high-quality briquette production.
Raw Material Purity Requirements
The purity of the feed material is fundamental to ensuring the normal operation of the equipment and the quality of the pressed blocks. During feeding, it is essential to ensure that the metal chips are pure and free of impurities.
Foreign objects that must be removed beforehand include:
- Stones and gravel
- Wood chips and splinters
- Plastics and rubber materials
- Dirt and soil particles
- Other non-metallic contaminants
These impurities not only affect the density and purity of the pressed blocks but may also wear down the pressing chamber, press head, and other core components of the equipment, even causing jamming, malfunctions, and affecting operational efficiency.
Raw Material Moisture Control
The moisture content of the metal chips must be strictly controlled during feeding to prevent damp raw materials from entering the equipment.
- Metal chips with excessive moisture are prone to clumping and sticking together
- Damp materials easily clog the feed inlet during feeding
- Moist materials make it difficult to form during the pressing process
- Results may include loose and cracked blocks
- Moisture content must meet equipment compatibility standards
Damp raw materials may also corrode internal equipment components, shortening the equipment's service life. It is necessary to ensure that the feed moisture content is evenly dried and controlled.
Feed Uniformity
The feeding process must maintain uniformity and stability, avoiding excessive or insufficient feeding.
- Overfeeding can cause blockages in the equipment cavity
- Excessive feeding increases the load on the equipment
- Overloading easily leads to component damage and block deformation
- Underfeeding results in uneven stress on metal shavings
- Insufficient feeding leads to inadequate block density and looseness
Feeding should be synchronized with the equipment's operating rhythm to ensure uniform filling of the cavity and consistent briquette quality.
Raw Material Size Matching
The size of the metal shavings fed must match the equipment specifications to avoid mixing in excessively large or small materials.
- Excessively large metal shavings are difficult to enter the cavity
- Oversized materials easily jam the feeding channel
- Jams affect operational continuity and efficiency
- Excessively small shavings are prone to flying during pressing
- Small particles create gaps affecting block quality
Appropriate processing of the metal shavings is necessary according to equipment requirements to ensure uniform size and compatibility with the equipment's feeding standards.
