HIGH-TECH MICROSPHERE PRODUCTION

About company

GRANULITE

Introducing energy-efficient lightweight aggregates – mineral microspheres, with a closed spherical shell and zero water absorption. They are used as components and additives in the production of goods and materials with light weight and resistance to high temperatures and high pressures. Microsphere-based products are used in the “Green Building” industry, in the production of composite materials with unique insulating properties.

Our company supplies microspheres with more than 10 years of proven experience of successful application in industry – since 2010 GRANULITE microspheres have been accredited by producers of insulating, refractory materials and leading global energy service companies.

Each stage of raw materials processing and final product production complies with the quality control system (ISO 9001:2015)

Technological microspheres

PRODUCTS

Our products are hollow mineral microspheres:

GRANULITE™ are cenospheres obtained after processing and stabilization from renewable mineral resources of the electric power industry.
GRANSPHERE™ — ceramic spheres from a composition of available natural raw materials and environmentally friendly volcanic glass. To date, the products are produced according to the developed technology for preparing raw materials based on natural volcanic glass and the improved technological process of its spherolization.

BENEFITS

Hollow spherolized mineral microspheres with a closed porosity provide:

Homogeneous material with specified parameters
Optimal strength-to-density ratio
“Zero" water absorption and high adhesion to binders and structural materials
High thermal insulation and fire resistance

energy saving products

Fine free flowing powder, consisting of homogeneous high-strength hollow spherical aluminosilicate particles. The production of stabilized cenospheres always requires careful selection, multi-stage processing of the original mineral raw materials.

The patented Granulite production technology allows to obtain a pure product without impurities, with excellent insulating characteristics – aluminosilicate hollow microspheres “Granulite ™” with a high content of Al₂O₃, high heat resistance and an excellent strength-to-density ratio.

Granulite™ cenospheres are used in aggressive and challenging thermobaric conditions, as a component of lightweight refractory and fire-retardant materials, energy efficient insulating building materials, with zero water absorption and low thermal conductivity.

PRODUCTION

The main sources of “white cenosphere” pure raw material of Aksu HPP and all processing from harvesting to the production of a full cycle of microspheres are carried out by TOO Kazcenospheres, Republic of Kazakhstan, Pavlodar region.

TOO Kazcenospheres executes a full cycle production of “Granulite” microspheres from selection and procurement of raw material, its stabilization, to final processing, followed by the release of a wide rangeof high-quality lightening microspherical additives.

Natural ingredients

ECOLOGY AND EFFICIENCY

The production is based on the use of available pure natural mineral raw materials, as well as the waste-free use of renewable mineral resources.

Transfer of energy in the processes of heat treatment with IR radiation (without heat loss)

Environmentally friendly technologies for processing mineral raw materials. Closed production cycle

Technological processes run by electricity

Complete absence of exhaust flue gases, low noise and dust levels

With integrated raw material sourcing, production processes and logistics, the highest quality standards are ensured throughout the entire supply chain.

Advantages of choice

Efficiency of microspheres application

Economic effect

Reduce the consumption rate of expensive binders and components in the compositions.
Spherical shape

Spherical shape of the microspheres helps to reduce the viscosity of the resulting composites, improves the fluidity of materials, provides better distribution and efficient filling of particles, as well as reduced shrinkage.
Refractoriness

The high melting point of microspheres makes them highly sought after by manufacturers of refractory materials, as it increases the thermal stability of materials to which microspheres are added, with relatively small linear changes.
Strength

The unique combination of "superlightness" and "strength" of microspheres allows the production of lightweight cements with a density of up to 1200 kg/m³ with stable and controllable parameters.

Due to their compressive strength, microsphere particles withstand high pressure conditions without loss of cement density and have higher strength compared to similar and more expensive industrial glass microspheres, providing approximately 25% weight loss compared to traditional mineral fillers.
Heat and sound insulation

Due to their low sound and heat conductivity, microspheres can be used as excellent insulating materials.
Resistance to aggressive environment

Can be used in a number of materials providing high resistance to acids and alkalis.

Cenospheres and ceramospheres

APPLICATION

Our lightweight additives meet the requirements for the development of new composite materials designed for long-term operation in challenging conditions at high temperatures, heavy and varied mechanical loads. Any technical problem that requires weight reduction with low thermal conductivity, high strength, smaller volume, increased resistance to erosion and aggressive environments can be solved using cenospheres and ceramospheres.

Our microspheres are in high demand among manufacturers of refractories and flame retardants, polyurethane, polyester, epoxy resins, PVC, construction, paints, abrasives, mortars, automotive, mastic and flotation products.
