OUTPUT

OUR ADVANTAGE

1. Energy-saving environment friendly

Advanced production process and large capacity for single production line with low heat loss. The advanced bag type dust collector, which is equipped in LECA equipment, keeps exhaust gas below 30mg/Nm3.

2. High degree of automation

Leca production line is fitted with temperature and pressure monitoring instrumentation, operating parameters of the computer display, and is capable of using advanced computer control to achieve automatic operation of the entire system.

3. Lost investment

Based on the features of Light Expanded Clay Aggregate (LECA), double-cylinder insert type rotary kiln controls the preheating and calcination process. The energy-saving vertical preheater is equipped in LECA production line with advanced process, and reasonable design and high level technology.

PROCESS

Henan Zhengzhou Mining Machinery Co.,Ltd has started the Light Expanded Clay Aggregate (LECA) equipment manufacturing since company foundation. We always trance the new technology developing on the LECA equipment manufacturing and have cooperate with the college and R&D institute to improve the equipment performance and function. Our LECA equipment have been widely used in Chinese LECA manufactures and won the good reputation from customers. We have begun the exported business since 2010 and create the good economic benefit. We adopt the energy saved technology and get the good efficiency.
