50,000-600,000(m³/a) Contaminated Soil Leca Equipment LECA
Production Line
Contaminated Soil LECA Production Line Introduction:
Contaminated soil is waste produced in modern industrial
production. Due to unorganized discharge or failure of the
discharge system, it penetrates into the soil layer, causing
changes in the physical, mechanical, and chemical properties of the
soil, directly affecting engineering activities or harmful to
humans. Health, animal reproduction, plant growth, etc. With the
implementation of my country's environmental protection policies,
everyone is exploring how to dispose of contaminated soil in a
harmless, resource-based and stable manner as solid waste.
Through the analysis of contaminated soil and continuous small and
pilot tests, our experimental center has explored a way to use
rotary kilns to bake ceramics, and truly realize the harmlessness,
resource utilization and stability of contaminated soil disposal.
Production capacity: 50,000-600,000 (m³/a)
Calcination temperature: 1100-1200℃
Main equipment: plug-in rotary kiln, single-cylinder cooler, vertical cooler,
roller crusher, twin-shaft mixer, double-roller granulator, stone
removal machine, secondary shaping machine
How to Produce the LECA Ceramisite
Contaminated soil undergoes preliminary stone removal, coarse
crushing, fine crushing, batching, mixing, aging, granulation,
calcination, and cooling to form building ceramsite. Due to the
high temperature stay in the rotary kiln for more than 30 minutes
and the calcination at about 1100°C, some heavy metals in the
contaminated soil are wrapped and oxidized and reduced to form
stable chemical elements, thereby achieving the purpose of
solidification. The produced ceramsite can be used in building
blocks, wall panels, bathroom backfill, garage roof backfill, roof
leveling, square tiles, flower cultivation, etc., while achieving
resource utilization and stabilization, reducing pollution. Soil
disposal points to a path to sustainable development.
Our Advantages:
The main goal is to achieve the reduction, harmlessness and
resource utilization of contaminated soil, sludge or solid waste
disposal
1. Our company combines the secondary combustion chamber technology
of hazardous waste incineration with the smoke chamber at the end
of the ceramsite production kiln, and exchanges the waste heat,
which is then used for drying general solid waste, reducing energy
waste and exploring ways to deal with flue gas.
2. Provide complete industry chain services from overall project
planning to detailed process formulation, process design, equipment
design and manufacturing, engineering installation, commissioning,
etc., with complete solid and hazardous waste treatment system
solutions
3. The company's pilot test line can conduct raw material analysis,
formula design, sample preparation, roasting, small tests, and
pilot tests of various sludge ceramsites.
