The invention is a vertical milling machine grinding grain stone rural Nianzishan inspired by. Modern vertical milling machine is developed from l906 onwards, it has been continually improved over the past century, experienced a roller by centrifugal force to put pressure on the spring-loaded, and now pressurized hydraulic pneumatic spring system. Is the softest material from the grinding of coal to medium hardness and brittle cement raw materials to cement clinker and slag.
LM Vertical Grinding Mill achieves lower energy consumption, stronger drying capacity, as well as lower abrasion and easier checks of core parts, saving operating costs greatly.
Materials linger in the grinding mill for a short time, which can reduce repeated grinding and is easy to detect and control the grain size and chemical component of the product.
The system is sealed in an integral manner and works under negative pressure, so that there is no dust spilling and the environment can keep clean.
