100,000 M³/A Leca Lightweight Expanded Clay Aggregate LECA Production Macchine

LECA Ceramsite Production Line Product Description:
Introduction to the production line: Clay ceramsite is an artificial lightweight aggregate made from clay with suitable composition. When the composition is not suitable, some other materials need to be added. It is processed into granules and expanded at high temperature in a rotary kiln. After years of research, Zhengkuang Machinery has developed energy-saving and environmentally friendly equipment suitable for use in ceramsite production lines, opening up a new process route for the construction of new environmentally friendly and energy-saving ceramsite.

• Production capacity: 50,000-600,000 (m³/a)
• Calcination temperature: 1100-1200℃
• Main equipment: plug-in rotary kiln, single-cylinder cooler, vertical cooler, air cooler, roller crusher, twin-shaft mixer, roller granulator, bag dust collector, fan, rotary screen, belt machine

LECA Ceramsite Production Line Working Principle:
The Rotary Kiln is usually working as following : The kiln is a cylindrical vessel, inclined slightly to the horizontal, which is rotated slowly about its axis. The raw material to be processed is fed into the upper end of the cylinder. While the kiln rotates, material gradually goes down towards the lower bottom, and may undergo a certain amount of stirring and mixing. Hot gases pass along the kiln, sometimes in the same direction as the process material (co-current), but usually in the opposite direction (counter-current). The hot gases may be generated in an external furnace, or may be generated by a flame inside the kiln. Such a flame is projected from a burner-pipe (or “firing pipe”) which acts like a large bunsen burner. The fuel for this may be gas, oil or pulverized coal.

LECA Production Line Main Equipment:

LECA Production Line Specifications:

LECA Ceramsite Production Line Product feature:
1. Support device: advanced shaft structure, automatic temperature measuring device and electrical heating.
2. Catch wheel: including two kinds mechanical wheel and hydraulic pressure.
3. Gears: single or double. Control the rotating speed by variable motor, DE machine and frequency variable motor. Be reliable, energy –saving, and efficient.
4. Cylinder tyre bolster: lower bolster has three types: fixed, zoom and floating. The structure is simple, replacement is convenient and won’t hurt cylinder.
5. Sealing equipment: there are many kinds for choice according to kiln models, including air cylinder edge sealing, spring edge sealing, and graphite block sealing and combination for above. The feather is adaptive for cylinder rotating and swing. And sealing effect is very good.
