Customized Ball Mill End Cap

Material: Carbon steel, alloy steel or according to customer's requirements ; Application: Cement/ Mill and Kilns;Mining and Minerals/Rotary Dryers; Certification: ISO 9001
Product Details:

Ball mill is mainly composed of cylinder, feeding end cover and discharging end cover, main bearing, feeding bushing, discharging bushing, power equipment, etc.

Ball mill end cover is one of the key part of ball mill, its structure is relatively complex, long production cycle, high precision of processing and assembling, so when compiling process routes, should fully consider its manufacturability.

Technical requirements:

1. The casting surface should be smooth,flat , the casting rounded corners not indicated are R30 - R50mm, not injection hole and edge chamfer not marked should be  2*45º

2  Artificial aging treatment after rough machining

3. For all processing surface after rough machining, ultrasonic testing inspections before the artificial aging,which should reach GB7233-87  Ⅱ standard

4. All liner plate bolt hole must be from the inside of the cone and  drilled

5. After finishing, magnetic powder flaw detection according to Q/HM6589-2015 and Q/HM6599-2015.

6.Total weight:16800kg
