How do i combine/aggregate 2 uplinks into 1 and load balance in EX4200 Juniper Switch?

Hi,

So i have 2 uplinks provided by my hosting, both are 1gbps and connecte to 46 & 47 port.

I was wondering how i can combine them into 1 connection and split the traffic between both?

My servers are connected from 0 till 16 ports (All even are public and all odd are private network).
