Materials is sent into stock bin by belt conveyor or bucket elevator, then conveyed from material silo to belt conveyor by disk feeder, belt conveyor carry materials into feed pipe. The gradient of newest energy-saving feed pipe must be larger than materials’ angle of crater in order that materials flow into dryer successfully. The drum of dryer is a rotary drum which is slightly at an angle with the horizontal line. Materials get in dryer from one side, heat carrier follows at the same time. Through the inner cylinder, middle cylinder, outer cylinder, arrive at discharging port, finally get into discharging silo. After heat carrier goes through dryer, materials carried in heat need cyclone dust collector to capture down. If a need to further reduce the dust content, it should go through bag filter or wet dust collector before discharging. Finally linear vibrating screen separates the qualified finished products from the dried materials.
Wet sand convey:Wet sand enter into wet sand hopper,through belt feeder and wet sand belt, convey wet sand to sand dryer.
Sand drying: After the wet sand enters the dryer, it rolls inside the dryer and comes in contact with hot air to fully dry it and turn it into dry sand.
Dust removal: When dry sand comes out of the dryer, a lot of dust will be formed, and the dust collector is a device that separates the dust from the flue gas.
Dry sand screening: Customize different screens according to customer requirements to screen the sand types required by customers.
Triple Pass Rotary Dryer has 3 drying zones in the 3 cylinders (internal, middle and external) which construct the rotating body. Heat processing of a product with high moisture content is done efficiently in those 3 drying zones. The product is put in from the inlet of the hopper, sent to the internal cylinder where heating of the product is made, then moves to the middle cylinder where evaporation of moisture is promoted further. The solid constituent of the product is gradually broken into pieces and discharged from the outlet via the third final drying zone. The hot air produced in the furnace is sent to the internal cylinder, passes through the middle and external cylinders. The hot air is then sent to the cyclone where dust is removed.
