A thermally efficient process for the expansion of perlite ore is described. The inlet port and burner of a perlite expansion chamber (preferably a vertical expander) are enclosed such that no ambient air can enter the chamber. Air and fuel are metered to the burner with the amount of air being controlled such that the fuel/air premix contains at least enough air to start and maintain minimum ...
Perlite is an igneous mineral composed by silicon, aluminum, oxygen and water. It can be expanded by heating it up at temperatures above 870 °C, then it becomes plastic, and the steam formed inside pressures out of the mineral. Maximum expansion is possible if the particles are heated up quickly, since the expansion degree strongly depends on the remaining water in the particles at the time ...

When the perlite expansion process is considered as a system, the components of this system are the combustor, the heating zone, the chimney, the cyclones and the filter group. The heating zone and the chimney are chosen as the control volume because the perlite expansion process occurs within these parts.
Development of perlite expansion process by using microwave technology. UPVLC, responsible for this task, worked on the development of a proper reactor for perlite expansion by microwave technology. A Microwave-assisted Fluidized Bed Reactor (MFBR) was designed and a continuous pilot-scale prototype was constructed and tested.
Microwave Energy for Expanding Perlite Ore. ... Perlite is extracted from the mines and crushed down to particles, which are fed in rotary kilns for carrying out the expansion process, then particles become less dense and often change their color from green, pale gray or even black, to white after expansion. ... in large amounts is less ...

Thus, perlite seems to be a very important material. In this paper, thermodynamics analysis of a perlite expansion furnace was performed. Both energy and exergy relations were derived for the considered system. Some parameters, such as losses, irreversibility and design etc., were used for determining the energy and exergy efficiencies.
US4347155A Energy efficient perlite expansion process. A thermally efficient process for the expansion of perlite ore is described. The inlet port and burner of a perlite expansion chamber (preferably a vertical expander) are enclosed such that no ambient air can enter the chamber.
A computational code has been developed based on a Eulerian–Lagrangian approach in order to model the combustion and the motion of perlite particles in a vertical expansion furnace. The expansion of a single particle, which takes place during its motion in the furnace, has been modeled by taking into account the perlite chemical composition and the gradual variation of the temperature ...

The production process of expanded perlite includes two key processes of preheating and expansion. (1) Preheating: According to the difference of origin and grain size, after the pearlite ore is preheated for 2-8 minutes at a temperature of 650-800 °C, the water content will reach the expansion requirement.
