Roller Conveyor Shot Blast Line
Inline pass-through blast machine with roller conveyor — purpose-built for continuous descaling of steel plates, beams and structural sections. MUSI Technology, based in Changzhou, China, designs and manufactures this equipment in-house and has delivered 800+ coating lines to 36 countries, with on-site installation and operator training included.
Continuous production for steel plates, H-beams and structural shapes with high uptime.
Roller conveyor shot blasting machine for steel plate and structure
A roller conveyor shot blasting machine passes steel plate, profiles, pipe and PEB structure through blast wheels on a roller table. It is the steel pretreatment line before painting for structural steel, shipbuilding and container plants, replacing chemical pretreatment for heavy sections. Roller width, section height and wheel count set the model.

Frequently Asked Questions
QQuestions buyers ask before ordering
quotation · price · lead time · installation · warranty
What information do you need to prepare a quotation?
Send part drawings or photos, the largest part size and weight, the material, the required output per shift, the paint or powder type and number of colours, and the available floor space, ceiling height and power or gas supply. MUSI engineers reply within 24 hours; a recommended configuration and quotation follow once your part data is complete.
How much does this equipment cost?
Budget depends on part size, throughput and the level of automation. Indicative ex-works ranges are published in our sandblasting and shot peening cost guide; a configured quotation is prepared from your part data.
What is the lead time?
Standard configurations ship in 30–60 days from contract signing and down payment; custom configurations take longer. The delivery date is fixed in the contract.
Do you install and train operators overseas?
Yes. MUSI engineers carry out on-site installation and commissioning and give 3–5 days of operator and maintenance training. MUSI has delivered 800+ coating lines to customers in 36 countries.
What warranty and after-sales support are included?
12 months full-machine warranty, 36 months on critical components and up to 60 months on structural parts. International customers get 24-hour phone response and 72-hour on-site arrival; spare parts ship from the Changzhou headquarters.
Can the environmental equipment be supplied with the line?
Yes. VOC treatment (RTO, RCO, activated carbon, zeolite rotor), dust collection and paint wastewater treatment are supplied with the coating line under one contract; MUSI has equipped 50+ coating facilities whose projects all passed local environmental compliance reviews.
