Product Description

The hollow shaft of the ball mill is the key part of the cement machinery. It is a special type of steel casting. It mainly plays the role of supporting and connecting the cylinder in the whole machine. is the bending force, and the barrel is subjected to the shearing force.The fillet at the root of the end plate of the hollow shaft of the ball mill is the stress concentration part, which is prone to blisters, pores and micro-crack defects during casting.In order to solve the problems that have plagued the company for many years, we have introduced the casting process simulation technology and improved the casting process of the hollow shaft of the ball mill, basically eliminating the defects of sand holes and air holes at the neck of the journal, and bringing the quality of the hollow shaft to a new level. .We can supply various kinds cast iron parts for thermal power plant, turbine hub and housing casting frame, engineering & mining machine parts castings etc. large -scale casting steel parts. The products includes: large wheel bands, grinding plates, gear, wheels, end cover, mid -empty shaft, moving beams, etc.Avicia, fuselage, columns, electrical hammer brackets, etc.; Medium and large metallurgical metallurgical rolling frames, bearing seats, slag tanks, etc.;(Upper seat board, lower seat board)
We have rich experiences in manufacturing large casting iron platform and machine tool chassis or body iron castings with machining process, max single weight we work with is over 50t.
We mainly produce carbon steel castings, low alloy steel castings, gray iron castings, ductile iron castings,etc. Our castings are widely used in the following industries: shipbuildings, construction machinery, wind power, etc.
Heavy Machining and Fabrication
Our company was founded in 1999, our factory currently has more than 1600 employees, covering an area of over 1,00,000 square meters, which has four sections: Equipment Assembly Dept., Metal Fabrication Dept, Precision CNC Machining Dept, Casting and Forging Dept.We provide full service fabricating service , from material supply, cutting and forming, rough machining, finish machining, welding assembly, and surface treatment, to the final packaging and transportation.

We have a complete welding platform, including plasma welding, strip surfacing, argon arc welding, TIG welding, laser welding, hand arc welding, and submerged arc welding equipment clusters.Welding methods include tube-sheet strip surfacing, automatic submerged arc welding, carbon dioxide gas shielded welding, argon tungsten arc welding, electrode arc welding, plasma welding, etc. The materials that can be welded are carbon steel, alloy steel, stainless steel, and non-ferrous metals such as copper, aluminum, and titanium.

To ensure that the quality strictly meets the requirements, we have special quality inspectors to supervise and review the product quality for all projects, and we are equipped with a variety of inspection methods. For welding, we have magnetic particle inspection, X-ray inspection and other methods to inspect the weld quality. For precision machined products, we use advanced three-coordinate testing equipment to check product size, flatness, parallelism, concentricity, etc. For precision machined surfaces, we will also use special testing equipment to check that the surface roughness perfectly meets the acceptance criteria. Moreover, we will custom make inspection methods to serve for their project.

We have rich experience in manufacturing precision metal components in various industries, such as tube sheets, machine bed, power station energy storage finishing tanks, and even CNC parts for medical industry etc.
Industries we served: Construction machinery, printing and dyeing, food machinery, new energy environmental protection, nuclear power equipment, pressure vessel, etc...
Our company has established a sound quality management system, and has passed different kind of welding production certification, such as the following:
