Finance a ball mill for mineral processing grinding circuits. $50k minimum, application-only to ~$400k, full underwrite for larger units. New and used mills financed.
Grinding is where mineral processing becomes expensive, and ball mills carry a significant share of that cost in every conventional grinding circuit. They consume more power per ton than almost any other unit operation in the plant, and their availability directly constrains the downstream flotation or leaching recovery that the whole project exists to achieve. Buying, replacing, or adding a ball mill is among the largest single equipment decisions a processing operation makes. We finance ball mills for gold, copper, zinc, silver, and iron ore concentrators, for industrial mineral processors, and for operations adding secondary or regrind capacity to existing plants.
Our minimum transaction is $50,000, and ball mill deals in practice range from $100,000 for smaller pilot or secondary regrind units to several million dollars for large production mills. Application-only approvals up to approximately $400,000 return a decision in 48 to 72 hours in most cases. Full underwriting for larger transactions closes in about one to two weeks, requiring three months of bank statements and operational documentation that establishes the processing context the mill will serve.
Ball Mill Specifications and What They Mean for Financing
Ball mills are defined by their shell diameter and shell length, which together determine the grinding volume and installed power. Small secondary or regrind mills might run two to three meters in diameter; large primary ball mills in high-throughput concentrators can reach five to six meters in diameter with proportional length, installed on drives exceeding several megawatts. The mill charge, the steel balls that do the grinding work, is a consumable and its cost is part of the operating expense rather than the capital acquisition, but the liner system, the bearings, and the drive are long-life components whose condition governs residual value.
For used ball mills, the key inspection points are the shell condition (checking for cracks, weld repairs, and shell deformation), the trunnion bearing condition, the ring gear and pinion wear, and the liner attachment system. A mill that has run for a decade in a hard-ore application with documented liner replacement cycles is a different proposition than one with the same hours and no service history. We assess used mills based on available documentation and request an independent inspection for transactions where condition records are incomplete.
Manufacturers commonly financed includeMetso Outotec, FLSmidth, Outotec (legacy), and regional fabricators for smaller custom mills. For gold and base metal processing, Metso and FLSmidth mills are the dominant installed base and carry the best market comparables for residual value assessment.
New Mills Versus Refurbished Units
New ball mills from major manufacturers carry lead times that can run six to eighteen months depending on the shell diameter, the drive configuration, and the manufacturer's production schedule. For operations with a defined commissioning date, that lead time has to be built into the capital timeline, and financing can be structured to close at delivery rather than requiring the borrower to carry interest on an idle loan during fabrication.
Used and refurbished ball mills are an active market. Mills that have been removed from decommissioned concentrators, refurbished through an OEM program, or sold through equipment dealers offer substantially lower acquisition costs than new units. A well-maintained mill with a documented rebuild history, including new liners, rebuilt trunnions, and a reconditioned drive, can provide many additional years of service at a fraction of the new-unit cost. We finance refurbished mills when the refurbishment pedigree and scope are clearly documented.
Pilot-scale and laboratory-scale mills used in metallurgical testing programs are at the smaller end of what we finance. These units, typically under one meter in diameter and used for comminution testing and process development, can sometimes qualify under our application-only program when the transaction falls within the approximately $400,000 threshold.
Loan and Lease Terms for Ball Mills
Ball mill financing terms typically run 36 to 84 months depending on the mill's age, size, condition, and the borrower's credit profile. Larger new mills from established manufacturers with documented production histories can support longer terms because the asset's expected service life, measured in decades at a well-maintained operation, comfortably exceeds even an 84-month loan. Older mills or units with limited documentation are typically financed at shorter terms with higher down payment requirements to keep the loan-to-value ratio appropriate to the uncertain remaining life.
Structure options include secured loans, capital leases with dollar-buyout provisions, and fair-market-value leases. Operations that want to preserve off-balance-sheet treatment may prefer the lease structure; operations that want to capture depreciation benefits underbonus depreciationorSection 179provisions should discuss the ownership structure with their tax advisor and then tell us which structure fits. We can accommodate either approach.
Sale-leaseback against owned ball mills is also available for operations that need liquidity. A mill that has been amortized on the books but still carries significant market value can be sold to a lender and leased back, generating cash at closing while operational continuity is maintained. We assess value based on current condition and comparable market transactions rather than accounting book value.
