Let $\mu$ be a positive Borel measure on the interval $[0,1)$. The Hankelmatrix $\mathcal{H}_\mu=(\mu_{n+k})_{n,k\geq 0}$ with entries$\mu_{n,k}=\mu_{n+k}$ induces the operator $$\mathcal{H}_\mu(f)(z)=\sum^\infty_{n=0}\left(\sum^\infty_{k=0}\mu_{n,k}a_k\right)z^n$$ on the space of all analytic functions $f(z)=\sum^\infty_{n=0}a_nz^n$ in theunit disk $\mathbb{D}$. In this paper, we characterize the boundedness andcompactness of $\mathcal{H}_\mu$ from Bloch type spaces to the BMOA and theBloch space. Moreover we obtain the essential norm of $\mathcal{H}_\mu$ from$\alpha$ Bloch type spaces to Bloch space and BMOA.
