Cement Ball Mill Maintenance
Lubrication system is in the key part to reduce mechanical wear and tear, including the ball mill. Generally, you should replace all the old lubricating oil and clean the machine thoroughly after the mill was put into work as long as one month. After that you should change the lubricating oil about every six months for each time.
What Is Autoclaved Aerated Concrete (AAC)
Autoclaved aerated concrete is a lightweight, durable, and energy-efficient building material made from natural raw materials such as sand, cement, lime, gypsum, and water. One of the main advantages of aerated concrete is its lightweight. It weighs about one-fifth of conventional concrete and is easy to handle and transport.
