Guilin Hongcheng Mining Equipment Co., Ltd. has made breakthroughs in the research and development of large-scale grinding process technology and equipment. The process technology and equipment are mainly used for the grinding system of cement raw materials, coal grinding, and cement preparation, as well as material crushing in chemical and metallurgical industries. The process features are: integrated crushing, sorting, drying, and powder collection, with less equipment, simple grinding equipment, low energy consumption, stable operation, small footprint, and low maintenance costs. Compared with the traditional ball mill, the power consumption per unit of grinding can be greatly reduced, and the output can be increased by more than 40% compared with similar equipment. In this project, several technologies such as vertical roll mills and new technology plum racks have obtained national utility model patents and are at the leading level in China.
Guilin Hongcheng Machinery is a professional production company specializing in the development, design and production of honing, crushing and ultrafine grinding equipment and mineral processing equipment. It has been repeatedly rated as one of China's top ten milling machinery manufacturers and China's leader in milling machinery. In the early 1990s, the company took the lead in introducing advanced technologies and processes from the United States, Germany, Japan, Australia, and other countries, established an internationally advanced production line and a first-class modern testing base, and established a milling machine research center to develop and process 1200. The grader of the fine degree of fineness, the current annual production capacity of the milling machine has reached more than 400 sets, has a number of awards such as "excellent technological innovation project" and "Chinese mill name brand" product titles, and has become the Guangxi industrial machinery Backbone companies.
For example, in the cement grinding system, the ball mill grinding system has always occupied a dominant position. However, the problem of high power consumption and low efficiency of the ball mill grinding system has not been effectively solved. To this end, Guilin Hong Cheng Machinery developed a large grinding process technology and equipment (which has obtained national patents), successfully and effectively reduced the power consumption of the system grinding unit, improved the grinding efficiency and equipment operation rate and wearing parts The service life, and greatly reduces the system maintenance costs. The process flow is: the material is broken into materials less than 20mm by a jaw crusher, lifted by a bucket elevator to a storage hopper, and then sent to the host cavity by electromagnetic vibrating feeder for grinding, the host cavity is supported in the plum rack The four roller devices rotate on the central axis, and the roller swings outward under the effect of centrifugal force, so that the roller presses the grinding ring and the roller rotates around the roller shaft at the same time. The material raised by the rotating blade is thrown between the grinding roller and the grinding ring, and the grinding and grinding effect is achieved due to the rolling of the grinding roller. The pulverized powder is blown by the air flow of the blower to the analyzer above the main machine for sub-screening. If the fineness is too coarse, it will still fall into the host machine. The fineness and conformity to the specifications will follow the wind and flow into the large cyclone collector. After collection, the powder will be discharged. The tube discharge is the finished product (the finished product particle size can be as high as 325 meshes). The purified air flows into the blower through the pipe at the upper end of the large cyclone collector. The air path is circulated. Except for the positive pressure from the blower to the grinding chamber, the airflow in other pipelines is All flow under negative pressure, indoor sanitary conditions are better. Since the moisture content of the material evaporates into gas when it is ground, the gas leaked into the air duct at the joints of the flanges, feed inlets, etc. in the pipeline causes the air volume in the circulating air path to increase. These increase the air volume through the blower and the host. The remaining air duct leads to a simple dust collector, and the powder that was carried along with the wind is collected and discharged. The energy-saving effect of equipment is obvious.
In addition, the large-scale grinding machine as a large-scale grinding system has significant technical advantages. The first is a new grinding system: 1. The new technology adopts a brand-new vertical roller grinding device. The grinding roller and the grinding ring are always in balance during the grinding process, forming a uniform line contact grinding zone. The height of the grinding roller and grinding ring increased from the original 230mm to 250mm, which increased the grinding contact area to a greater extent. 2. The classifier adopts a forced turbine classifier to extend the granularity of the finished product from the original 80-325 mesh range to the 80-800 mesh range. 3. The wind transport and finished product collection system was upgraded to a negative pressure, secondary dust collection and high efficiency dust collector, so that the finished product can be collected more thoroughly. The second is reliable performance: new technology (plum racks and vertical roll device), advanced and reasonable structure. The machine vibration is very small, the noise is low, the mechanical operation is stable, and the performance is reliable. The third is high-efficiency energy-saving: the material has greater processing capacity and higher efficiency in the grinding time of the unit. In comparison with the R-type pendulum mill, the total power remains unchanged, the output increases by more than 40% year-on-year, and the unit power consumption cost is saved by more than 30%. It is a truly energy-efficient mill product.
