③ Positive and negative pressure combination

④ Dense phase pneumatic conveying

Dense phase pneumatic conveying

① Dense phase conveying is also called sending tank or warehouse pump conveying

② There are two ways of sending tank transportation: 

     sending tank (storage pump) positive pressure honey phase transportation,
