Independent developed " Cost-Effective Substitution" Intelligent Force Exciter Will Realize Cost Reduction & Efficiency Increase



1


In the past, high-end mining & processing equipment, core spare parts and components, and many cutting-edge technology fields were heavily dependent on the supply of internationally renowned brands; facing the problem of technology monopoly.


While, in recent years, technological monopolies are being broken one by one with the rapid advancement of Chinese technology, and domestic technological innovations are gradually "taking place of foreign monopoly" by the high cost-effective products.


The National Energy Group Shendong Coal Group Company is a pioneer and model of cost-effective alternatives. Many years ago, Shendong Group realized that relying on imported equipment and core components brought great uncertainty (import cycle) to production stability and increased procurement costs. In order to solve this issue, Shendong actively promoted the program of domestic manufacturing in high-end equipment and made positive contributions to the transformation and upgrading of the national coal industry.


At the end of 2015, Shendong has developed and promoted 218 sets of mining equipment, with a total original value of 11.29 billion yuan, 3.38 billion yuan was saved compared with imported procurement; 43870 kinds of spare parts have been developed and 2.275 million pieces have been applied in total, saving about 1.08 billion yuan compared with imported procurement, which effectively reduces procurement costs and ensuring safe production.


According to incomplete statistics, the company consumes 521,700 imported spare parts every year. There are 80 categories and 19,585 items suitable for high-end spare parts development, mainly covering electrical, mechanical, hydraulic, washing, and other business fields.


During the 30 years from 1987 to 2018, the domestic manufacturing has grown into an important vein of mining industry, such as the technologies of 8.8 meters ultra-large mining height, roof-cutting and pressure relief mining without coal pillars, intelligent mines, "Internet + coal", and “Industry 4.0”, etc. The pattern of technological innovation in Shendong has undergone historic changes. More advanced science and technology independently developed by Shendong have broken the long-standing monopoly of foreign equipment and software in the coal industry and filled the domestic gap.


HOT has been learning from Shendong. In recent years, HOT has experienced the exploration and practice process from the development of spare parts to core equipment, and some of its products have filled the gaps in the field of domestic mining and processing equipment.


longwall mining technology of soft rock to a hard rock project in Mexico

2


  • In 2017, HOT successfully applied the longwall mining technology of soft rock to a hard rock project in Mexico (underground copper-cobalt mine). HOT is the second company in the world to apply longwall mining technology to hard rock mining. (The first one is CAT who used an improved longwall mining system in a platinum mine in South Africa in 2016);

Some of our Force Exciters

  • In 2020, HOT develops Intelligent force exciter that can be substituted for most brands...
HOT has always insisted on R&D investment, followed up the world's leading mining and processing technology, and successfully developed equipment one after another with independent intellectual property rights and developed equipment suitable for high-yield and efficient mining technology.

Chengdu Alpha Industrial Intelligence Co., Ltd. (ALPHA) has developed intelligent force exciter with the function of predictive maintenance technology for vibration screen fault, which will effectively improve the service life of exciter, realize in advanced warning of failure, and guarantee the production continuity of vibrating screen.

Similarly, the IoT sensor monitoring technology is used to upload the data to the AIPLA Cloud through a unified receiving device for data analysis. According to the current fault models of all kinds of vibrating screens owned by ALPHA, the fault pre-diagnosis is carried out for the operation of the vibrating screen. The frame diagram is as follows:

A wireless vibration temperature sensor is used to measure vibration temperature data of force exciter. The sensor is installed at the end of bearing in force exciter, and it supports two ways of temperature measurement, and one of the temperature probes is external for measuring the temperature of lubricating oil. Then, two high-precision acceleration angle sensors will measure the vibration intensity and vibration angle at the same time, which are respectively installed at the inlet and outlet of the vibrating screen, on each side, to monitor the vibration intensity of the equipment during operation and the vibration balance of the screen body.

Through monitoring, it can make a prediction before the vibration screen failure, arrange the maintenance plan in advance, avoid the risk of the shutdown caused by sudden failure, and maintain the equipment when necessary, so as to ensure the continuous and stable operation of the vibrating screen and reduce the maintenance cost!
