Vertical roller mill innovations of Great Wall Machinery

September 4 to 5, the 11th G20 Summit will be held in Hangzhou, China. The theme of the summit is “build innovative, dynamic, linkage and inclusive world economy” and the summit lists “blueprint of economic growth by innovation” as a key issue for the first time. Chaeng (Great Wall Machinery) constantly extends product and industrial chains with the concept of technology and science first, especially paying attention to the development of high value-added and high-tech products with the feature of energy saving and emission reduction. Our company has won the important results in the fields of vertical roller mill, ball mill, rotary kiln, etc., forming the core competitiveness of company itself, which consolidates the foundation for our company to become the domestic first-class grinding system comprehensive service supplier.

Innovations of Great Wall Machinery

Technologies innovated by Chaeng obtain Utility model patent certificates issued by State Intellectual Property Office

A kind of feeding device applied in vertical roller mill (patent number: ZL 2015 2 0349738.9): effectively reduce the power consumption of belt conveyor transmission and civil engineering cost of system and allow vertical roller mill to run smoothly at the same time.

· A kind of powder selecting device applied in vertical roller mill (patent number: ZL 2015 2 0349704.X): improve more than 15% of efficiency and reduce 5% of power consumption.

· A kind of dismounting device for taper sleeve of grinding roller (patent number: ZL 2015 2 0349716.2): effectively improve the efficiency of dismounting taper sleeve of grinding roller and reduce dismounting cost.

φ4.2×13m double slide ball mill (patent number: ZL 2010 2 0285841.9): fundamentally solve the problem in like products that “cannot operate constantly because of overheat of sliding bearing at the discharge end”.

Innovation for intelligent control device of vertical roller mill

Intelligent control device of vertical roller mill allows the operator to perform statistical data of the equipment and operate at any time according to situations in the field, which is adaptable, easy to operate and reliable to use. It can ensure the smooth running of vertical roller mill. The device supports internet remote operation, human-computer interaction of which is accurate, convenient and reliable.

Design for the belt plate of rotary kiln

By reference to relevant technology and combined with production technology department, Chaeng replaces “floating plate” of rotary kiln by “replaceable plate”, which is convenient for manufacturing process and improving 20% of production efficiency. This design obtains users’ consistent high praise.

Multi-purpose vertical roller mill

Multi-purpose vertical roller mill with high efficiency and energy saving means that only one vertical roller mill can achieve the grinding of various materials (cement clinker, auxiliary material and slag particles admixture, etc.). This kind of vertical roller mill has been used in the yearly output of 1 million tons cement/ 0.6 million tons slag powder production line and operation effect has exceeded exceptions after 100 days’ operation.

In the future, Chaeng will continue to cooperate with design institute of building materials, colleges and universities and well-known building materials machinery experts to enhance the quality of the product through innovation and research and development to provide high value-added equipment for customers and give more value for the investment of customers!
