Let $n\geq 3$ be an integer. $n$ balls are arranged in a circle, and are labeled with numbers $1,2,\cdots,n$ by their order. There are $10$ colors, and each ball is colored with one of them. Two adjacent balls are colored with different colors. For balls with each color, the total sum of their labeled numbers is independent of color. Find the minimum possible value of $n$. 
1. **Understanding the Problem:**
   - We have \( n \) balls arranged in a circle, labeled \( 1, 2, \ldots, n \).
   - Each ball is colored with one of 10 colors.
   - Adjacent balls must have different colors.
   - The sum of the labels of balls of each color must be the same for all colors.
   - We need to find the minimum possible value of \( n \).

2. **Conditions and Constraints:**
   - Since adjacent balls must have different colors, each color must appear at least once.
   - Let \( S \) be the sum of the labels of all balls. Then \( S = \frac{n(n+1)}{2} \).
   - Since there are 10 colors and the sum of the labels of balls of each color must be the same, each color must sum to \( \frac{S}{10} \).
   - Therefore, \( 10 \) must divide \( S \), i.e., \( 10 \mid \frac{n(n+1)}{2} \).

3. **Divisibility Condition:**
   - For \( 10 \mid \frac{n(n+1)}{2} \), \( n(n+1) \) must be divisible by 20.
   - Since \( n \) and \( n+1 \) are consecutive integers, one of them must be divisible by 2 and the other by 10, or one must be divisible by 4 and the other by 5.

4. **Finding the Minimum \( n \):**
   - We need to find the smallest \( n \) such that \( n(n+1) \) is divisible by 20.
   - We also need to ensure that \( \frac{n(n+1)}{2} \geq 10n \), which simplifies to \( n(n+1) \geq 20n \), or \( n+1 \geq 20 \), i.e., \( n \geq 19 \).

5. **Checking Values:**
   - For \( n = 19 \):
     \[
     19 \times 20 = 380 \quad \text{(not divisible by 20)}
     \]
   - For \( n = 20 \):
     \[
     20 \times 21 = 420 \quad \text{(divisible by 20)}
     \]
     \[
     \frac{20 \times 21}{2} = 210 \quad \text{(not divisible by 10)}
     \]
   - For \( n = 24 \):
     \[
     24 \times 25 = 600 \quad \text{(divisible by 20)}
     \]
     \[
     \frac{24 \times 25}{2} = 300 \quad \text{(divisible by 10)}
     \]

6. **Verification:**
   - For \( n = 24 \), the sum of the labels is \( \frac{24 \times 25}{2} = 300 \).
   - Each color must sum to \( \frac{300}{10} = 30 \).
   - It is possible to arrange 24 balls in a circle with 10 colors such that adjacent balls have different colors and each color sums to 30.

Conclusion:
The smallest possible value of \( n \) that satisfies all conditions is \( 24 \).

The final answer is \( \boxed{24} \).
