Building Gypsum Production Line and Factory Setup

A building gypsum (plaster) production line is a complete industrial system designed to crush, calcine, grind and pack gypsum plaster under controlled process conditions. The line produces construction gypsum for plastering and related applications.

From an industrial perspective, gypsum manufacturing is important because it combines accurate crushing and screening, controlled calcination, efficient grinding and reliable packaging to achieve consistent setting time, strength and fineness. The process relies on a defined sequence of unit operations that must be correctly engineered, sized and integrated.

Primary materials typically include gypsum rock and packaging materials. The core machinery set consists of impact crushers, screens, calcining kilns (Löwern or high-burn type), mills, bag filters and packaging machines.

The Industrial Department supports investors who want to establish a new gypsum plant as well as existing operators who need repair, overhaul, capacity expansion or automation of their current lines. Projects can start from an empty site or from an operating facility that requires technical upgrading.

Whether the goal is a green-field turnkey gypsum plant in Iraq, Kurdistan Region, Afghanistan or other regional markets, or the modernization of an existing line in Iran, engineering, machinery supply or manufacturing, installation, commissioning and ongoing technical support can be provided under defined contractual scopes.

Production Line Overview

The building gypsum line is engineered as an integrated process system covering rock crushing, screening, calcination, grinding, dust collection and packaging. Design capacity is determined during the engineering phase and can typically range from 50 to 200 tonnes per day.

Main machinery groups include crushers, screens, calcining kilns, mills, bag filters and packaging machines. Supporting infrastructure covers electrical power, gas and process water.

Manpower requirements depend on the degree of automation. Quality control covers fineness, setting time and strength.

Manufacturing Process

1. Crushing – Gypsum rock is crushed in an impact crusher.
2. Screening – Material is sized and stored.
3. Calcination – Gypsum is calcined in a kiln.
4. Dust Collection and Grinding – Product is ground and dust is collected in bag filters.
5. Screening and Packaging – Finished gypsum is screened and packed.

Machinery & Equipment

• Impact Crusher and Screen – Prepare the rock. Position: first stages. Importance: particle size for calcination. Quality impact: incorrect size affects calcination efficiency. Maintenance: hammers, screens and drives. Sahi Rasa support covers design, installation, repair and spare parts.
• Calcining Kiln – Converts gypsum to plaster. Position: core stage. Importance: degree of calcination and capacity. Quality impact: over- or under-calcination affects setting time. Maintenance: refractories, burners and controls.
• Mill and Bag Filter – Grind and de-dust the product. Position: after calcination. Importance: fineness and environmental control. Quality impact: incomplete grinding affects workability. Maintenance: media, liners and filter bags.
• Packaging Machine – Packs the finished gypsum. Position: end of line. Importance: logistics and presentation. Quality impact: incomplete filling causes losses. Maintenance: valves and bag handling systems.

Factory Layout & Building Requirements

Typical areas include rock storage, crushing and screening, calcination, grinding, packaging, quality control, utilities and staff facilities. Exact area is determined during engineering.

Utilities

• Electricity: 380 V three-phase, 50–100 kW
• Gas: 100–300 m³/h
• Water: 5–10 m³/day

Turnkey Factory Setup

An investor can start from an empty site. The project can be accompanied through feasibility, engineering, design, machinery, installation, commissioning, training and commercial production.

EPC & PMC

Projects can be executed under EPC or PMC approaches within defined contracts.

Machinery Repair

Existing gypsum lines can request inspection, repair and spare-parts support for crushers, kilns, mills and packaging machines.

Machinery Overhaul & Refurbishment

Older equipment can be overhauled and control systems upgraded.

Capacity Expansion

Capacity can be increased by upgrading kilns or grinding capacity.

Industrial Automation

PLC control of temperature, flow and packaging is typical.

Supply Chain

The Supply Chain Department supports packaging and additive supply.

Packaging

Bags and secondary packaging are integrated according to market requirements.

Branding & Product Development

Support for product development and technical documentation is available when required.

Market & Country Sections

Services are available in Iran, Iraq, Kurdistan Region, Afghanistan and other listed regional markets.
