3. high ball strength
4. easy to control water in ball
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 mix with normal sweet soil in order to reduce the weight of plants and landscapes soils.

Cost Reduction of Maintenance
Thanks to durability and lacking of destructive effect on building components, specially on installation system. Leca plays a good role to lower maintenance cost moreover in case of masonry or repairment , destruction of components goes to minimum.
Prevention of Wasting Space
Raising walls with Leca blocks prevent wasting of interior space in building. However, other constructional materials may lessen the interior space.
Accelerating Implementation Process
Having various shapes and longer dimentions, Leca light weight blocks accelerate the implementation procces. Lower the labor energy cost and turn over also goes higher.
Coast Reduction of Transportation
Since the Leca aggregate which used to produce light weight concrete and precast panels is too light, transportation cost decrease and its lightness facilities the moving of Leca concrete components.
Our LECA productions are broadly used in as follows:
A: Garden plants growth,
B: Oil and gas proppant material,
C: Foundry and Cast sand and grits,
D: Water and sewage filtration,
E: Building materials,
F: Road and highway materials.

3. LECA manufacturing technique
No matter which kind of raw material adopts, the general process are: homogenization of raw materials, granulation, sniter and cooling. According to the classification of raw material, the LECA produce process can be divided into: 3.1. Plastic method: which is suitable for clay and clay raw material, and its process is as follows: clay -plasticizing, homogenizing - granulating - roasting - cooling - finished products. 3.2. Balling method: which is suitable for fly ash or other pulverized raw materials, and its process is as follows: fly ash- homogenizing, balling, granulating - roasting - cooling - finished products. 3.3. Grinding powder into ball method: which is suitable for raw materials of shale, clay shale and coal gangue, and here is the process: drying- grinding - prewetting - granulating - roasting - cooling - finished products, additive. 3.4. Crushing (dry) process: which is suitable for raw materials of shale, and the process is as follows: shale - crashed and classified - roasting - cooling - finished products. 3.5. Fuel: according to the situation of local fuel supply, use bituminous coal, heavy oil or gas.
4. The Capacity of LECA production line
Depends on local LECA requirements and capital available, the LECA production line capacity could be 20,000~30,000 m³ per year, 50,000m³per year, 100,000m³ per year.
