Lime and Gypsum

Lime, limestone and gypsum powders are key ingredients in products such as plasterboard, mortars, fillers and soil conditioners, but their abrasive and dusty nature demands carefully engineered handling systems. Rospen designs and supplies conveying, weighing and dosing solutions that move these materials safely and efficiently from intake and storage through to mixers, kilns and board or product lines.

Moving Lime and Gypsum Reliably

Mineral plants often need to transfer high throughputs of lime, limestone and gypsum over significant distances between unloading points, silos and processing equipment. Rospen’s experience in construction materials handling supports robust, dust‑tight transfer of these abrasive powders.

• Pneumatic conveying systems configured for lime and gypsum powders, with line routing and velocities selected to limit wear and blockage.
• Options for low‑velocity or dense‑phase style conveying when product quality or pipework life are critical considerations.
• Heavy‑duty components and layouts that integrate with existing construction materials handling infrastructure.

Consistent Dosing for Mineral‑Based Products

Plasterboard, mortars and other gypsum‑ and lime‑based products require controlled addition of base powders and minor additives for consistent performance. Rospen provides weighing and metering equipment designed to handle these materials accurately in demanding environments.

• Volumetric and gravimetric feeders for limestone, gypsum and additives feeding into mixers, kilns and board production lines.
• Loss‑in‑weight and screw feeders specified with suitable wear‑resistant materials and seals to cope with continuous operation on abrasive powders.
• Integration with plant control systems for automated batching, feed‑rate control and traceable production data.

Managing Dust from Lime and Gypsum

Fine mineral powders can pose challenges for housekeeping, environmental control and equipment reliability if not properly contained. Rospen’s systems are configured to limit dust emissions and support safe, dependable operation.

• Enclosed transfer points, hoppers and discharge arrangements to reduce fugitive dust during conveying and dosing of lime and gypsum.
• Interfaces for dust extraction and filtration at unloading, silo filling and key transfer locations.
• Designs that account for pressure, venting and other safety requirements associated with pneumatic conveying and storage of mineral powders.

Complete Lime and Gypsum Handling Systems

Rospen already supports leading construction materials companies with systems for gypsum plants and complex dosing of minor and micro‑additives. That expertise extends naturally to broader lime and gypsum handling projects in the minerals and building products sectors.

• System design and equipment selection for new or upgraded lime and gypsum intake, conveying, storage and dosing installations.
• Mechanical, electrical and control integration so conveying, weighing and downstream process equipment operate as a coordinated system.
• Ongoing technical support and service to maintain performance and availability in harsh mineral processing environments.
