Mining material hoisting gearbox

Innovative design and integration advantage: Based on the MHB standard industrial gearbox platform, it carries out derivative development and skillfully integrates modularization and special design. The modular design ensures the universality and interchangeability of parts, greatly reduces the manufacturing and maintenance costs, and improves the production efficiency.

Advanced gear shape optimization technology: Adopting unique gear shaping technology, the gear profile and tooth direction are corrected accurately. When the gears mesh, it effectively improves the contact state, so that the load is evenly distributed on the tooth surface, which significantly reduces the shock and vibration.

Superior hardened gear quality: The gears are designed with hardened gears and comply with high international standards such as ISO, AGMA and DIN. This high standard design gives the gears excellent strength and wear resistance, enabling them to easily cope with the heavy-duty working conditions in the building materials, cement and mining industries, as well as the long-term stable operation requirements of the grain industry.

Multiple seals for flexible adaption: There are many kinds of seals, which can be flexibly selected according to different application conditions. Whether in a dusty mining environment, a high humidity cement production scenario, or a relatively clean grain processing workshop, it can effectively prevent dust, moisture and other impurities from entering the gearbox, ensure the cleanliness and normal circulation of the internal lubricant, and protect the gears and bearings and other key components from wear and corrosion.

 

Wide torque coverage: The torque range is from 6.6 - 236 (kN.m), a wide torque range that can meet the diverse torque requirements of different equipment from large heavy-duty chain elevators in the building materials and cement industry to light-duty bucket elevators in the grain industry.

Flexible Speed Ratio Adjustment: The range of speed ratios from 25 to 90 can be flexibly adjusted according to the requirements of different elevator heights, conveying speeds and material characteristics.

Various power adaptations: Rated power ranges from 13 to 1,773 (kW), a wide range of power ratings allows it to adapt to a wide range of hoist sizes and operating conditions, from bucket elevators in small grain processing plants to heavy-duty hoisting equipment in large-scale cement mining enterprises.

 

In the building materials and cement industry, it is widely used in a variety of chain and belt elevators, which undertake the important tasks of transporting cement raw materials such as limestone, clay, iron powder, etc. from the ground to the silo at a high place, as well as conveying cement clinker from the production link to the finished product storehouse. In the mining industry, it is used for the lifting and transportation of ore, slag and other materials to ensure the smooth transportation of materials in the process of mining and processing. In the grain industry, to provide power for the bucket elevator, wheat, corn, rice and other grains from the bottom of the warehouse to the bottom of the processing equipment or storage of high, is an indispensable key equipment for grain processing and warehousing links.

 

Before installation, the installation foundation should be accurately measured and evaluated to ensure that its strength, flatness and stability meet the requirements of gearbox installation, to prevent vibration and displacement during operation due to foundation problems, which affects the life of the equipment and operational safety.

Before the first operation, the gear box should be fully cleaned internally, check the installation of gears, bearings, shaft seals and other components and lubrication status, according to the specified oil level and oil requirements for lubricant filling. Check and adjust the chains, belts, couplings and other parts connected to the outside to ensure that they are firmly connected and properly tensioned.

During operation, establish a regular inspection system to check the oil temperature, oil pressure, vibration, noise and other key indicators of the gear box, and observe whether there is any leakage at the sealing place, and the wear and tear of chain, belt and other transmission parts. According to the running time and working conditions of the equipment, rationalize the maintenance cycle, timely replacement of lubricating oil, filters and other wear parts, gears, bearings and other key components of the wear test and precision adjustment.

For the long-term out of service or seasonal out of service equipment, before decommissioning should do a good job of equipment cleaning, anticorrosion, rust treatment, the gear box lubricant discharge clean and properly stored. Before re-activation, the equipment needs to be fully inspected and maintained, and the preparatory work should be carried out in accordance with the requirements before the first operation to ensure that the equipment can be safely and reliably put into operation again.
