Cold-Process Lead Granulator: Fume-Free, Efficient Production
Introducing the RTM ColdCut 2.5T, the revolutionary machine that transforms lead ingots into uniform lead granules without melting. By eliminating furnace heating, it slashes energy costs, prevents toxic lead fumes, and dramatically increases operator safety.
- 100% cold mechanical cutting eliminates harmful lead fumes and smoke emissions.
- High hourly capacity of 2.5–2.75 T/h directly feeds large ball mill operations.
- Energy consumption is reduced by up to 70% compared to traditional melting furnaces.
A Revolution in Lead Processing
The RTM ColdCut 2.5T directly addresses the biggest challenges of traditional lead granule production: pollution, energy waste, and safety risks.
- Zero Lead Fumes & Emissions
A purely mechanical process that generates no smoke, odor, or toxic lead emissions, creating a safer, compliant working environment.
- Massive Energy Savings
Avoid the high electricity or gas bills of running large melting furnaces. The ColdCut uses only a fraction of traditional energy.
- High, Continuous Output
Delivers a stable 2.5 to 2.75 tons per hour of uniform lead granules, perfectly matching the feed requirements of industrial ball mills.
- Maximum Operator Safety
Completely eliminates the burn risks, molten metal splashing, and hazardous heat exposure associated with traditional foundries.
- Uniform Granule Quality
Cold extrusion and precision cutting produce consistently sized granules (75–100g) ideal for lead oxide ball milling.
- Fully Automated Production
An advanced PLC system controls the entire sequence from ingot infeed to granule discharge, minimizing manual handling.
The Cold Granulation Process
A streamlined, automated workflow that transforms solid ingots into uniform granules.
-
Step 1Ingot Feeding
Standard 45 kg lead ingots are automatically loaded and conveyed into the high-tonnage hydraulic processing unit.
-
Step 2Cold Extrusion
The hydraulic ram powerfully compresses the solid ingot through an extrusion die, forming dense continuous lead strips.
-
Step 3Granule Cutting
Synchronized heavy-duty rotary shear blades cut the extruded lead strips into precisely measured, uniform granules.
-
Step 4Automated Output
The finished lead granules discharge via an integrated scraper conveyor, ready for ball milling or storage bins.

Watch the clean, safe, and efficient cold process of turning solid lead ingots into uniform granules.
The cold cutting process eliminates the most hazardous and costly part of traditional lead granulation: melting. This provides three major advantages: 1) Zero Lead Fumes: protects workers and the environment from toxic lead vapor; 2) Massive Energy Savings: avoids continuous furnace heating; 3) Enhanced Safety: removes risks associated with handling and splashing molten lead.
A single RTM ColdCut 2.5T unit has a production capacity of 2.5 to 2.75 tons per hour. This is specifically calibrated to match the continuous feed requirements of one large 24T ball mill machine or two standard 14T ball mill machines in lead-acid battery manufacturing lines.
Routine maintenance primarily involves monitoring the hydraulic system oil levels and filter status (using L-HM46 anti-wear oil), inspecting the cutting shear blades and extrusion die for wear, and ensuring conveyor pathways remain clear. A full preventive maintenance schedule is included with each machine.
