Ball mill end cover

Introduction

Ball mill end cover is one of the key components of the ball mill, whose structure is relatively complex, requiring long manufacturing period and high-precision processing and assembly, so the process technical demands should be fully considered during planning process route.

The end cover is located at both ends of the ball mill cylinder and is supported on the bearing, mainly used to support the material, the cylinder and the medium. The fillet at the root of ball mill trunnion is the stress concentration part.

Single Weight: 1-150T

Applications: Building material industry

Main material: ZG230-450

Customziable: Yes

Advantages

1, high-quality raw materials, mature technology

Use high-quality raw materials and mature technology to guarantee the quality. CHAENG has a wealth of experience in manufacturing ball mill, in the production process, we continue to adopt new technologies and new process to enhance its wear resistance and pressure performance. Our advanced level-2 flaw detection equipment can detect the interior of the end cover accurately to assure the quality.

2. Components are sealed well, no leakage problem

CHAENG feed cover can be produced for a specific device, making adjustments to a certain degree to make end cove joint better with feed components without gaps, to prevent material leakage problem.

3. Stable operation, long service life

CHAENG ball mill end cover adopts high-strength steel, and its structure is optimized by professional engineers according to the operation characteristics of ball mill, to greatly ensure the long-term operation stability and prolong the long service life.

Process flow























 

The first step: Simulation and modeling

Before casting, numerically simulate the casting process by CAE software to analyze the molding process, predict and optimize quality of ball mill end cover.

The second step: pouring and heat treatment

The qualified raw and auxiliary materials shall be put into the arc furnace according to the proportion, and the sampling of hot metal shall be carried out to perform the spectral analysis. After qualification, the pouring shall be carried out according to the principle of "low temperature and quick casting", and the pouring time and temperature shall be recorded.

The third step: Flaw detection, finishing

Finally, cut the pouring riser and burr etc. CHAENG has professional mechanical polishing teams and large-scale blasting apparatus, which can effectively improve the appearance quality of support roller, to meet customer’s requirements on surface finish. Moreover CHAENG take use of advanced detection equipment for non-destructive testing to ensure the internal quality of supporting roller, strictly stop any defective goods from leaving the factory.
