AI Technical Summary
The transmission system of existing cement ball mills has problems of high power consumption and high cost, especially the cost and power consumption of large gears.
The 4-cm thick steel plate is welded into a steel frame flange, and the casting of high manganese steel parts is designed to design non-standard large gears and pinions, and the φ4.2m ball mill is transmitted through the steel frame conveying system to reduce the transmission pressure and power consumption.
Through this design, 3200KW of power is saved per hour, reducing the power consumption and cost of the transmission system, while improving the efficiency of the system.

Abstract
Description
Technical Field
[0001] It is a ball mill for producing cement Background Art
[0002] The national standard large gear has a maximum diameter of 5.3m, the transmission is 3.8m, the ball mill transmission pressure is 6.3 times, and the cost is very high. The φ4.2m center shaft transmission ball mill used by Shiyang Haoyu Cement Plant has a radius of 2.1 meters and a torque of 3550kw per hour. Summary of the invention
[0003] The present invention uses 4 cm thick steel plates to make inner and outer flanges, which are screwed and welded into a steel frame, and is cast with high manganese steel parts. The non-standard large gear has 480 teeth and Φ8.4m, a tooth pitch of 5.5 cm, and a transmission pressure of 2.1 meters (21 times). It is matched with a non-standard small gear with 55 teeth and Φ92 cm, and a steel frame non-standard large gear to transmit a Φ4.2m ball mill, saving 3200KW of electricity per hour.
[0004] Use a 9-die 200-teeth φ1.818m reduction gear, a 9-die 38-teeth φ36cm reduction pinion, a non-standard 55-teeth φ92cm transmission mill pinion, and a transmission mill pressure of 21 times. Specific implementation plan
[0005] Use 4 cm thick steel plates to weld into steel frame flanges with inner diameters of 4.2m to 4.6m for the inner flange and 6m to 6.4m for the outer flange. The flange width is 20 cm. First, cut the bevel and use carbon dioxide shielded welding to form the flange. Use 16mm steel plates to press into 52 cm wide and 15 cm high channels. 28 pieces of steel form a steel seat. Use 2 cm thick steel plates as the seat surface of the steel seat. The steel seat is 60 cm wide and 1.2m high. The steel seat is φ6.6m. Use 28 square steels to form a non-standard large gear bracket. Use screws to connect high manganese steel parts to form non-standard large teeth to form a φ8.4m non-standard large gear.
[0006] The central axis of the reduction gear is connected to the non-standard small gear, and the non-standard large gear of the combined mill transmits the φ4.2m ball mill at 14.8 revolutions per minute.
[0007] Steel frame and steel seat non-standard large gear 480 teeth φ8.4m, non-standard small gear 55 teeth φ92cm, 9-mode reduction large gear 200 teeth φ1.818m. Equipped with 9-mode reduction small gear 38 teeth φ36cm, 380VYR rotor winding 10-level motor 350Kw, 680 revolutions per minute.
[0008] Mill speed calculation: motor 680 rpm x 38 teeth of small reduction gear ÷ 200 teeth of large reduction gear x 55 teeth of non-standard small gear of mill ÷ 480 teeth of non-standard large gear of mill. Calculation formula: 680x38=25840÷200=129.2x55=7106÷480=14.8 BRIEF DESCRIPTION OF THE DRAWINGS Figure 1 : Schematic diagram of the steel frame and steel seat non-standard large gear transmission energy-saving ball mill, Figure 2 : Front view of energy-saving ball mill with steel frame, steel seat and non-standard large gear transmission.
