Our company has mature integrated production capabilities in casting, precision machining and heat treatment of large heavy castings. We specialize in the research, development and mass production of high end mining machinery wear resistant castings. Our factory can mass produce high manganese steel, high chrome steel, alloy steel, ductile iron and other series of high quality castings. Our products cover complete transmission and wear resistant accessories for ball mills, jaw crusher wear parts, autogenous mill and semi autogenous mill liners, and a full range of mining and heavy industry accessories. They can fully adapt to various domestic and imported large mining, building materials and metallurgical grinding and crushing equipment.

The ball mill girth gear is the most core heavy duty transmission component in ball mills, semi autogenous mills and autogenous mills. It undertakes the task of driving the rotation of the whole mill shell. The equipment has large load, long running time and complex force, so it has extremely high requirements for casting material strength, toughness, wear resistance and overall precision. The girth gear produced by our company adopts dense precision casting technology. The material is uniform, with no porosity, no sand holes and no shrinkage defects. After large scale gear hobbing and gear milling precision machining, the tooth profile is accurate, the tooth surface is smooth and the meshing is uniform. The product has high transmission efficiency, low running noise and strong overload resistance. It is not easy to have problems such as tooth breakage, tooth chipping, excessive wear and transmission vibration. The overall service life is far superior to ordinary cast gear rings. According to customer equipment parameters, drawing dimensions and working conditions, we can produce integral type and split type half structure girth gears, and support custom machining of various non standard specifications.

Ball mill girth gears are widely used in industrial fields such as mining ore dressing, cement and building materials, metallurgy and chemical industry, sand and aggregate production, powder processing and large heavy industry grinding. They are mainly used in various dry and wet ball mills, autogenous mills, semi autogenous mills, rotary kilns and other large heavy load equipment, and serve as the main transmission component to drive the continuous operation of the equipment shell.

The product is suitable for harsh working conditions such as high hardness ore, heavy load impact, continuous operation and much dust. It can output power stably for a long time, with stable transmission and low failure rate. It effectively reduces equipment downtime and maintenance times, reduces enterprise equipment operation and maintenance costs, and is an indispensable core heavy accessory for large grinding production lines.

All girth gear products of our company strictly implement the standardized production process of heavy industrial castings. After the blank casting is completed, professional heat treatment is uniformly adopted. Through multiple processes such as quenching and tempering, quenching and tempering, the internal metallographic structure of the casting is optimized, casting internal stress is effectively eliminated, and the overall strength, tooth surface hardness, impact toughness and fatigue resistance of the gear ring are greatly improved. This fundamentally avoids quality problems such as deformation, cracking, tooth surface spalling and early wear during long term operation of the equipment, and ensures long term stable operation of the equipment.

The company implements a strict quality inspection system throughout the whole process. Each finished girth gear completes a full set of inspection items to fully control product quality. Hardness testing is used to verify tooth surface wear resistance and load bearing performance. 3D full area scanning is used for precision verification of overall dimensions, strictly controlling key precision data such as outer diameter, tooth profile, tooth pitch and end face runout. MT magnetic particle testing is used to check fine casting defects on the tooth surface and surface layer. UT ultrasonic non destructive testing is used to detect hidden problems such as deep cracks and voids inside the casting. Material composition testing is used to strictly control raw material ratio and ensure material standards and stable performance. Precision dimension testing is carried out to strictly control assembly tolerances and ensure accurate on site installation and docking. Metallographic analysis is used to inspect the internal microstructure of the casting and ensure that product mechanical properties fully match heavy industry and heavy load use standards. Strict quality inspection at every level and full process control prevent defective products from leaving the factory.

Our company provides one stop customized and supporting services for large mining castings. We support batch supply of standard specification girth gears and custom machining according to non standard drawings, samples and working conditions. According to customer equipment model, shell parameters, working load and material hardness, we can match the most suitable material and process solution to ensure maximum product adaptability and service life.

Before sales, we provide professional technical consultation, parameter docking, model selection, process solution optimization and other services. The production process is fully traceable, and production progress can be followed at any time. Before delivery, a full set of quality inspection data and test reports can be provided. The factory has sufficient production capacity of large equipment and can undertake single large castings and large batch foreign trade orders, with stable and controllable delivery time. A professional technical after sales team is equipped to provide installation guidance, commissioning suggestions and daily maintenance solutions, timely solve various problems encountered by customers during use, and provide long term stable high quality supply and technical guarantee for domestic and overseas customers.

According to the characteristics of large heavy girth gears, our company adopts high standard protective packaging specially for foreign trade export. The product surface is treated with rust prevention, anti corrosion and dust prevention. Key tooth surfaces are independently wrapped for protection to avoid collision and scratches. Large products are packed with thickened solid wooden boxes and steel frames for reinforcement, combined with buffer protection structures, to prevent deformation, wear, moisture and rust during long distance transportation.

We support multiple logistics transportation methods such as sea transport, land transport and air transport, suitable for foreign trade order delivery in various regions around the world. We have long term cooperation with large regular logistics channels, with stable transportation, stable timeliness and high cargo integrity rate. According to customer foreign trade customs clearance requirements, we can sort out and provide a full set of shipping documents, quality inspection materials and customs clearance documents, support customized packaging and delivery solutions, and fully meet foreign trade export standards.
