Demolition Robot Application in Ball Mills of Cement Industry Ball mill is a key equipment for grinding materials in the cement, silicate product, new building material, refractory, fertilizer, black and non-ferrous metal ore beneficiation and glass ceramic production industries. In construction and mining industries, the ball mill consists of main parts: feeding part, discharging part, turning part and driving part. The turning part which is the core part of the ball mill mostly consists of metallic alloy metal liners and lifters with their sizes and shapes designed especially for grinding applications together with plates and bars made of high chromium alloys or manganese series steels as per international specifications. These parts rotate together with the drum body and are responsible for raising the materials and providing good grinding results. The main technical specifications of the ball mill include processing capacity, mill diameter, length and power of the lab ball mill machine. As the first choice of many cement enterprises for the pre-grinding of raw materials and the grinding of clinker, the cement ball mill has many significant differences from other ball mills in terms of structure and performance. The cement ball mill has a small diameter and a large length barrel relative to its diameter. There are various types of balls with different diameters inside the mill. On the inner wall of the barrel, there are lining plates with different shapes. These complex structures help to improve the grinding effect. The operating principle of the ball mill is relatively simple while its performance is very complicated. The factors that influence the operating efficiency mainly include the filling ratio of steel balls, the size of balls, the ratio of large, medium and small balls, the speed of the mill, the viscosity of the material, the temperature of the material, the particle size of the feed, the intensity of the material and so on. The grinding effect of the ball mill depends on the friction and impact of the steel balls or ore particles in the mill, that is, the energy transfer generated when the particles collide with each other. Therefore, the ball mill can not only grind materials well, but also homogenize and blend them. Ball mill is one of the key equipment in cement industry for crushing and milling cement raw materials.

The working arm consists of three parts, providing an unprecedented range of motion, allowing rock drilling, prying, rock crushing and installation of anchor rods in any direction. In addition, the equipment uses a hydraulic system and does not require compressed air, which can maximize the reduction of facilities required at the working face. Electric drive ensures zero carbon emissions from these robots during operation. The same demolition robot can perform multiple tasks such as stripping, rock drilling, prying, mine tunnel maintenance, drilling, etc. It can not only improve the production efficiency of mines, but also improve the safety and sustainability of mining operations. Application 1: Crushing Large Blocks One demolition robot can be placed on a fixed grid or in a blast chamber to crush large blocks without the use of explosives or any unnecessary material handling. We now provide specifications ranging from 0.7 tons to 12 tons. The power-to-weight ratio of each specification is 2 to 3 times that of conventional excavators. Application 2: Ultra-deep Thin Vein Mining Deep vein mining requires equipment with high maneuverability and durability. Although robots can now be selected for large-scale mixed mining, these equipment are not suitable for ultra-deep thin veins. The demolition robot has other advantages such as high safety and high productivity of remote operation, high flexibility, high precision, etc. Some gold mines have achieved the above purpose by increasing the demolition robot in their deep vein mining. The demolition robot stitches its excellent power-to-weight ratio, which is usually equivalent to machines twice as large as existing equipment, and its efficiency is far greater than the most advanced pneumatic leg drill.
