80-120 mm Calcium Carbide Stone – 300 L/KG, Big Lumps for Big Jobs

You don’t see 80-120 mm every day. Most suppliers sell medium sizes because they’re easier to screen and pack. But some processes actually need big chunks – slow, steady gas release, fewer fines, and less dust in the generator.

That’s where our calcium carbide stone comes in. We crush and screen it specifically for customers who want large lumps. Gas yield: 300 L/KG. That’s as high as it gets.

Where This Big Calcium Carbide Stone Comes From

Our factory is in Inner Mongolia. We’ve been making calcium carbide for years, with an annual output of 36,000 tons. Not the biggest in China, but big enough to give you consistent quality and flexible packing.

The calcium carbide stone you see here comes straight from our furnaces. We cool it, crush it, and screen it to 80-120 mm. No shortcuts. No mixing in broken pieces.

Why 80-120 mm? And Why 300 L/KG?

Big lumps react slower than small granules. That’s not a flaw – it’s a feature. Some acetylene generators are designed for a long, steady gas flow. Some steel desulfurization processes don’t want a violent reaction. Large calcium carbide stone gives you control.

The 300 L/KG yield is real. We test every batch. You’ll get a certificate with each shipment showing the actual number.

Where Do People Use This Size?

We export to over 50 countries. Our 80-120 mm calcium carbide stone is popular for:

• Large acetylene generators – the kind that feed continuously for days.

• Steel desulfurization – some lances work better with bigger lumps that sink slowly into molten metal.

• Chemical plants that need a controlled reaction rate.

• Calcium cyanamide production – the big pieces hold up better in rotary kilns.

If you’re not sure whether 80-120 mm fits your process, ask us. We’ve seen enough applications to give you an honest answer.

Packaging – 50 kg or 100 kg Drums, Your Choice

We pack our calcium carbide stone in steel drums. You pick the weight:

• 50 kg drums – easier for manual handling. A 20' container holds 450 drums (22.5 tons).

• 100 kg drums – fewer drums, less steel. A 20' container holds 225 drums (22.5 tons).

Which one gives you a better cost? That depends on your warehouse setup. We offer both. No pressure.

Custom Drum Colors – Pick Any Shade

Grey drums are boring. Tell us a color. We have 11 RAL shades in stock, or we can match your custom code. For example:

• 80-120 mm → Dark grey drums

• 50-80 mm → Black drums

• 25-50 mm → Red drums

Your forklift driver sees dark grey – he knows it’s the big calcium carbide stone for the main generator. No label reading.

Your Markings (唛头) – Painted, Not Stickered

Stickers fall off in heat or rain. We paint your markings directly on the drum. Send a PDF or AI file. We’ll print:

• Your company logo

• “Calcium Carbide Stone – 80-120 mm – 300 L/KG”

• Net weight (50 kg or 100 kg)

• Batch number and production date

• “DANGER: Reacts with water. Flammable gas.”

• UN1402 / Class 4.3

• Destination port or consignee details

We’ve done markings in Thai, Arabic, Spanish, French, Vietnamese, Indonesian. No extra charge for standard text.

Mix Different Sizes in One Container

You don’t have to buy a full container of only 80-120 mm. Tell us what else you need. For example:

• 10 tons of 80-120 mm (dark grey drums)

• 6 tons of 25-50 mm (red drums)

• 4 tons of 7-15 mm (blue drums)

All in one 20' container. One freight bill. One customs clearance. That’s how a flexible calcium carbide supplier works.

Loading and Shipping – Tianjin Port, Two Weeks

Our warehouse is in Tianjin, less than 5 km from the port. That means we load fast. From deposit to shipment, count on two weeks lead time.

We’ve shipped to over 50 countries – Vietnam, Indonesia, Thailand, Philippines, Nigeria, Egypt, Brazil, Argentina, Poland, Turkey, South Africa, and many more. We know the documents each port asks for.

Certificates We Provide

We don’t have REACH. If your destination needs it, please check locally. But we do have:

• ISO 9001

• SGS inspection reports (pre-shipment or upon arrival)

• BV (Bureau Veritas)

• Full SDS in English, French, Spanish, Arabic

• GHS-compliant drum labels

• Origin certificate, commercial invoice, packing list, bill of lading

For most buyers in Asia, Africa, South America, and the Middle East, this is enough.

Storage – Up to 2 Years in a Dry Place

Big calcium carbide stone lasts longer than small granules because less surface area touches moisture. Still, you need to follow the rules:

• Store drums off concrete floors (use pallets).

• Keep temperature below 40°C, humidity under 50%.

• Away from water pipes, sprinklers, or leaky roofs.

• Always reseal drums after opening.

In a dry warehouse, our calcium carbide stone stays good for 2 years. In humid coastal areas, use within 18 months.

Safety – Short and Direct

Water + calcium carbide stone = acetylene gas. Acetylene + spark = explosion. Never open a drum in wet weather. Never use water on a spill – use dry sand. If a drum gets wet by accident, evacuate. Do not move it.

We put warnings on every drum. Train your people.

Payment Terms – Flexible

We offer:

• L/C at sight

• T/T (30% deposit, balance against copy of bill of lading)

• Negotiable for regular customers
