Mesin Roll Forming Silo Keluli Bijirin

What does a steel silo roll forming machine make?

It makes corrugated, curved wall panels for bolted grain silos, plus the stiffener posts that hold the shell together. One line uncoils the steel, levels it, punches bolt holes, forms the corrugation, curves the panel to the silo radius and cuts it to length.

What coil thickness and width can the line run?

1.0 to 2.0 mm thick and 800 to 1,250 mm wide. The gantry pre-cutting device handles up to 1,250 mm by 2.0 mm, and the feeding guide adjusts across the full 800 to 1,250 mm range.

How many forming stations does a silo panel line need?

18 to 20 roll stations for a standard corrugated silo wall panel. Rollers are GCR15 with a chrome plated surface at 58 to 62 HRC, on 100 mm 40CR quenched shafts, driven by a 45 kW main motor through a gear box.

How is the flat corrugated panel curved to the silo diameter?

A four roller online curving device bends the panel after the mill. The minimum radius is 0.95 m and the radius is set through the PLC with a 2.2 kW servo drive. A separate curving unit is an option when the budget is tight.

What length tolerance can a buyer expect?

Plus or minus 1.5 mm per finished panel. An Omron encoder measures length, and the hydraulic cut fires in sync with the first punch position so every hole lands in the same place.

What decoiler capacity does a grain silo line need?

A 15 tonne double bevel hydraulic uncoiler. It takes coils with a 508 to 610 mm inside diameter up to 1,500 mm outside diameter, with a hydraulic coil car and a 5.5 kW uncoiling drive.

Can punching, forming and curving run in one pass?

Yes. The standard flow is uncoiling, feeding and levelling, gantry pre-cut, hydraulic punching, roll forming, online curving, hydraulic cut-off and collection. Two hydraulic punching units run from one tank, with SKH51 or DC53 dies at 58 to 62 HRC.

Which standards should the panel drawing follow?

Buyers usually specify galvanized coil to ASTM A653 or EN 10346 and design the silo shell to EN 1993-4-1. The roll tooling is cut from the panel drawing those documents produce, so send the drawing before tooling starts.

What decides the price of a grain silo roll forming line?

Coil width and thickness come first, then station count, then the punching dies and whether curving is inline or separate. An automatic stacker and a second punching unit add to the total.

What should I send to get a firm quote?

Send the panel profile drawing, steel grade and thickness, target silo diameter, required output, the hole punching drawing and your plant voltage. Those six items let the roll tooling be designed once instead of twice.
