PCC Equipment

Handan Metallurgical Engineering & Research Co., Ltd. is one of the most reliable manufacturers and suppliers of pcc equipment in China. With a professional production team, we are able to meet the needs of the majority of our customers. Welcome to buy high quality pcc equipment made in China here from our factory.

The PCC process production is from the chemical point of view , apparently extremely simple.

Capacity: 30,000-300,000TPA

The production process begins with the limestone decarbonation (CaCO3) in a kiln, from which it's obtained lime (CaO) and gases (CO2).

The lime is slaked with an exothermic process, in a slacker obtaining slurry of lime hydroxide in water excess ( Ca(OH)2 + nH2O ) that is purified from the heavier impurities.

The slurry produced in this way is put in close contact with gases rich of CO2 coming from the kiln, realising the re-carbonation that bring again to the formation of a slurry of CaCO3 that will be used as such, for example in paper industry, or dehydrated and dried to obtain a powder finely dispersed.

Acting on the combination of some variable of process as:

river depuration / lime milk

lime reactivity

slacking temperature

slurry concentration

CO2 concentration

Process water additive

insemination

it's possible to determine the future composition of carbonate crystals (calcite - aragonite) obtaining the control of the three first parameters distinguishing the PCC specific surface, granulometry and white grade.

MER after many years of technologies development concerning lime production and its under products, using the specific technologic support of two PCC specialists at worldwide level, has begun to deal in the engineering and construction of plants for PCC production.

PCC equipment adopts advanced thermal and stress analysis soft parts scientific design, and special refractory materials to ensure high efficiency, energy saving and stable production, the quality of the products are welcomed by the world.

PCC equipment is the core production equipment of calcium hydroxide from quicklime. The structure consists of shell, mixing shaft, transmission system, spray system and control system.

Merxh-c digester is a new production equipment developed on the basis of absorbing foreign advanced technology, and its technical performance is synchronized with the world's advanced level. This type of digester consists of a three-stage digester and a dust collector. Unit, the true middle primary digester is double shaft type, the shaft speed is adjustable, the secondary digester is single shaft, the tertiary digester is single shaft. The unit strengthens the mixture of material and water, enhances the aging energy of the digester, so that the carboniferous can be digested to the maximum extent, and the product quality can be improved to the maximum extent.
