Ceramsite(LECA) Production Line

LECA (Light Weight Expanded Clay Aggregate) is an aggregate made of expanded clay at average 1200 in rotary kiln, the Yielding gases are expanded by thousands of small bubbles as long as this temperature and porosity will appear by many voids and honeycombs at these round shape aggregates when melted materials become cold. LECA is a manufactured aggregate which has many advantages compare with natural lightweight aggregate and since 1917 has used under different brand name in USA and Europe countries. skype: gary102884

Our company (dajia mining ) can help you design, produce and install the LECA Production Line with capacity 30000-80 0000t/y).

LECA broken equipment:
Our shale crusher equipment include jaw crusher, cone crusher, impact crusher, mobile crushing machine.
leca milling equipment:
Screening to achieve a certain granularity, raw materials are sent into the ball mill grinding chamber. The ball mill cavity equipped with 90 tons of steel balls, can grind shale powder to 10 mesh. Continuous impact force act on a mixture of shale and clay to reduce water content low to 10%.   skype: gary102884

LECA(ceramsite) production process:
Shale production process is as follows: mining - primary broken - second crushing - screening - temporary storage- Feeding - sintering - finished grading screening - piled up - transportation (bagging).
