Product Description

LECA, which stands for the lightweight expanded clay aggregate, is an important construction materials that widely used in gardening, concrete aggregate, box filling, hydroculture, and so on, and the LECA production plant is similar as the oil proppant production plant, as both of them needs to be calcined the green pebbles at high temperature, and the main difference between the two plant is that it is not necessary to crush and grind the raw materials for the LECA production plant, just needs to mix the clay thoroughly before granulating, while it needs to crush and grind the raw materials for oil proppant production plant before granulation. and the general flowchart of the LECA production plant is: materials feeding----mixing----granulation---shaping----rotary kiln---screening---packing, usually the rotary kiln for the two plant is also different, the rotary kiln for the leca production plant is variable rotary kiln, which means the diameter of the rotary kiln is different. Yet the rotary kiln for oil proppant production plant is cylinder rotary the main equipment for the LECA production plant includes feeding machine,mixing machine,granulator,shaping machine,rotary kiln,rotary cooler,screening machine,packing and belt conveyor.

Usage of LECA:

Common uses are in concrete blocks, concrete slabs, geotechnical fillings, lightweight concrete, water treatment, hydroponics, aquaponics and hydroculture.

LECA is a versatile material, and is utilized in an increasing number of applications. In the construction industry, it is used extensively in the production of lightweight concrete, blocks and precast or incast structural elements (panels, partitions, bricks and light tiles). LECA used in structural backfill against foundations, retaining walls, bridge abutments etc., in addition it can reduce earth pressure by 75% compared with conventional materials, and also increases ground stability while reducing settlement and land deformation. LECA can drainage the surface water and groundwater to control ground water pressure. LECA grout can be used for flooring (finishing) and roofing with thermal and sound insulation.

LECA is also used in water treatment facilities for the filtration and purification of municipal wastewater and drinking water as well as in other filtering processes, including those for dealing with industrial wastewater and fish farms. LECA has uses in agriculture and landscapes, it is used as a growing medium in hydroponics systems, and blended with other growing mediums such as soil and peat to improve drainage, retain water during periods of drought, insulate roots during frost and provide roots with increased oxygen levels promoting very vigorous growth. LECA can be mixed with heavy soil in order to reduce the weight of plants and landscapes soils.

lECA Production Plant introduction:

Lightweight expanded clay aggregate (LECA Production line) or expanded clay (exclay) is a light weight aggregate made by heating clay to around 1,200 °C (2,190 °F) in a rotary kiln. The yielding gases expand the clay by thousands of small bubbles forming during heating producing a honeycomb structure. LECA has an approximately round or potato shape due to circular movement in the kiln, and is available in different sizes and densities. LECA is used to make lightweight concrete products and other uses.

ECA is usually produced in different sizes and densities from 0.1 millimetres (0.0039 in) up to 25 millimetres (0.98 in),commonly 0-4 mm, 4-10 mm, 10-25 mm and densities of 250, 280, 330, and 510 kg/m3. LECA boulder is the biggest size of LECA with 100–500 mm size and 500 kg/m3 density.

Some characteristics of LECA(LECA production line) are: lightness, thermal insulation by low conductivity coefficient (as low as 0.097 W/mK[1]), soundproofing by high acoustic resistance, moisture impermeable, incompressible under permanent pressure and gravity loads, non–decomposition against severe condition, fire resistant, Ph of nearly 7, freezing and melting resistance, easy movement and transportation, lightweight backfill and finishing, reduction of construction dead load and earthquake lateral load, perfect sweet soil for plants, material for drainage and filtration.
