Briefly description of the leca Production Line
LECA consists of small, lightweight, bloated particles of burnt clay. The thousands of small, airfilled cavities give LECA its strength and thermal insulation properties. The base material is plastic clay which is extensively pretreated and then heated and expanded in a rotary kiln. Finally, the product is burned at about 1100°C to form the finished LECA product.
LECA production line is mainly used in oil field and the finished product, building materials , gardening , refractory insulation materials, Chemical and so on. ceramic sand is adopted as oil pressure support agent.
Light expanded clay aggregate is producing in more than 20 countries with different brands name, Some countrieswhich produce aggregate with almost the same industrial way are as:Italy, Denmark, switzerland, Norvey, Germany, Finland, Portugal, U.K, and Iran with brand of Leca.Russia, Poland, Sweden,China, with the brand of Keramzite. South Africa with the brand of Argex. Spain with the brand of liapour.
1. LECA Production Line --granulating machine and main type
Granulating machine is suited for the construction, petroleum, chemical, refractory insulation materials and other industries powdery materials granulation.. Such as it is the essential equipment to product ceramic sand .Following simple introduced a ceramic:Shale ceramic.
1. Coal ash ceramsite
2. Clay ceramsite
3. Shale ceramsite
4. Construction ceramsite
2. LECA Production Line --granulating machine Components:
Granulating disc is primarily composed of disc( including circular weir ,general weir height 0. 1~0.25D) and transmission machine. The dischas a certain angle, usually 45 to 60 degrees, speed 30r/min.
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.
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.
