Save time and money with IPP’s ready-to-ship kilns designed for continuous and batch thermal processing

Used kilns are high-temperature process units used for chemical and physical transformations in solid materials. These systems provide controlled heat treatment environments for applications like calcining powders, firing ceramics, or thermally decomposing compounds. With more than 47 years of industry leadership, IPP supplies used, secondhand and surplus kilns from 20 global plant sites and maintains a massive inventory of 15,000+ ready-to-ship systems.

IPP offers rotary kilns, tunnel kilns, shaft kilns and lab-scale units from trusted OEMs including Harper, Metso, FLSmidth, Carbolite, and Nutec Bickley.

Primary uses across industries

• In ceramics and refractories, for firing clay-based materials into hardened forms
• In chemical and metallurgical operations, for calcining, thermal decomposition or roasting ores and salts
• In cement and lime production, for thermal processing of limestone, dolomite and other minerals
• In battery, catalyst and advanced material manufacturing, for sintering powders and activating materials under precise conditions

Types of materials processed

• Oxides, carbonates, sulfates and other mineral-based powders
• Ceramic components and refractories
• Specialty chemicals and advanced materials
• Metal-containing solids and intermediates

Common materials of construction

Kilns are engineered for high heat, abrasion resistance and chemical durability:

• Carbon steel or stainless steel shells for structural strength
• Refractory brick or ceramic linings for thermal insulation and protection
• Special alloy internals for handling corrosive or reactive compounds

Key features of industrial kilns

• Direct-fired or indirect-fired heating systems
• Zoned temperature control for precision processing
• Gas, electric or fuel oil-powered designs
• Continuous (rotary or tunnel) or batch configurations
• Customizable residence time, atmosphere and temperature profile
