No you can't because blockchain.info don't share private key of your bitcoin address with you, you should had move those bitcoin from blockchain wallet to paper wallet or bittrex before 1st august.
However if you are holding those bitcoin in your imported bitcoin address in blockchain.info wallet than you should import private key of that address in Bitcoincash supporting wallet.
This is not true /or not entirely true/.
If you have an OLD Blockchain Wallet, you could expert your Private Key in a seconds. Just test it.
Setting > Addresses > More Options > Private Key.
But I don't know is it valid for new wallets.
