Buying Metal Chips Briquetting Machine? Watch This First before signing any order
This all-in-one buyer's guide breaks down every non-negotiable factor, common purchasing traps, machine type comparison and supplier screening standards to help you pick the most cost-effective briquetter matching your production scale.
1. Confirm Your Metal Chip Type First
All metal chips briquetting machines are not universal. Compression pressure, mold design and feeding structure must match your raw swarf material, otherwise you will get loose, fragile briquettes or frequent machine jams.
Ferrous Metal Chips (Steel, Iron, Cast Iron)
Hard, dense turnings require high hydraulic pressure ranging from 200T to 1250T. Loose cast iron filings demand a thickened mold liner and reinforced feeding screw to prevent abrasion.
Non-Ferrous Metal Chips (Aluminum, Copper, Brass)
Soft metal swarf only needs 50T–200T pressure. If you mix aluminum and steel chips, choose a multi-purpose briquetting machine with adjustable compression strength.
Special Materials
Stainless steel, titanium alloy, grinding sludge and fine metal powder need customized anti-corrosion hydraulic systems and fine filtration oil recovery modules.
Key reminder: Send your actual metal chip samples to suppliers for briquetting test before payment. Test reports can prove whether the machine fits your waste material perfectly.
2. Calculate Daily Chip Output to Match Machine Capacity
Overbuying high-capacity metal chips briquetting machines wastes capital and power; undercapacity leads to unprocessed stacked chips and production delays. Calculate your average daily scrap volume in kg/h before inquiry:
Small CNC workshop: 50–500kg/h → Vertical compact metal chips briquetting machine
Medium auto parts factory: 500–2000kg/h → Horizontal single-output hydraulic briquetter
Large foundry & recycling yard: Over 2000kg/h → Double-output fully automatic briquetting line with conveyor feeding
Most suppliers mark theoretical maximum output. Ask for real continuous working capacity data instead of nominal parameters.
3. Must-Have Feature: Integrated Cutting Fluid Recovery System
For machining factories using coolants and lubricants, oil recovery is the most profitable function of a metal chips briquetting machine.
Premium models separate 95%–98% oil from metal chips during compression:
Recovered coolant can be reused in CNC machines to cut fluid purchasing costs
Oil-free briquettes sell for 15–30% higher prices to scrap dealers
Comply with local environmental waste discharge regulations
Low-cost cheap briquetters skip built-in oil separators, leaving oily chips that get price deductions and trigger environmental inspection penalties. Never compromise this core module.
4. Horizontal vs Vertical Metal Chips Briquetting Machine: Which Fits Your Shop?
Vertical Metal Chips Briquetting Machine
Pros: Small footprint, low investment, easy to install, suitable for limited-space small workshops
Cons: Lower single-hour output, manual feeding required for large chip batches
Horizontal Hydraulic Metal Chips Briquetting Machine
Pros: High continuous capacity, automatic screw feeding, stable briquette density, convenient maintenance
Cons: Larger floor space, higher upfront cost
For unmanned production lines, pick horizontal double-output metal chips briquetting machines to double processing efficiency without extra labor.
5. Judge Hydraulic System Quality to Reduce Long-Term Failure Rate
The hydraulic station is the core of any metal chips briquetting machine. Low-quality hydraulic parts cause oil leakage, insufficient compression pressure and frequent shutdown maintenance.
