Water Cooling Jacketed Screw Conveyor for Slurry and Sand

Product Description

Screw conveyor with jacketed troughs and hollow auger used for drying slurries biomass

Our heating and cooling screw conveyors indirectly transfer heat to or from the product by introducing a heat transfer medium such as cool water, hot oil or steam through a special trough jacket and/or the pipe and hollow flights of the screw conveyor. Achieving the specified exit temperature of the product is accomplished by calculating the surface area of the auger and designing the system flow to match the heat load requirements of the application. A properly designed system will be very cost-effective when compared to other heating and cooling screw conveyors. Ever Lucky Machinery  designs and manufactures heating and cooling auger conveyors to meet the needs of many industries, such as Chemical, Minerals Processing, Food, Power and Wastewater Treatment. Heat Transfer Screw Conveyors are referred to by many different names Ash Coolers Fly Ash Screw Conveyors Thermal Screw Conveyors Screw Conveyor Cooler Screw Heat Exchangers Cooling Screw Conveyors Hollow Flight Screws Heating Augers Cooling Augers

 

 

Screw conveyor classification:
According to screw conveyor drive classification
1. If the length of U-shaped screw conveyor is less than 35m, it is a single-axis driving screw.
2. If the length of U-shaped screw conveyor is greater than 35m, it is a two-axis driving screw.
According to the screw conveyor middle hanger bearing type

1. M1- is a rolling bearing, adopts type 80000 sealed bearing, and the shaft cap has a dust-proof sealing structure. It is commonly used in areas where it is difficult to refuel, no refueling, or oil contaminates the material. The sealing effect is good, and the hanging shaft has a long service life. Temperature of conveying material ≤ 80°C.

2. M2- is a sliding bearing, equipped with a dustproof sealing device, a cast copper tile, an alloy wear-resistant cast iron tile, and a copper-based graphite less oil-lubricated tile. Commonly used in the transmission of material temperature is relatively high (t ≥ 80 °C) or transport water containing larger materials.
According to screw conveyor material classification
1. Ordinary carbon steel U-shaped screw conveyors - Mainly used in industries where cement, coal, stone, etc. wear out, and there are no special requirements for materials.
2, stainless steel U-shaped screw conveyor - mainly applicable to food, chemical, food and other industries that have requirements for the delivery environment, cleanliness, and will not produce pollution on the material, the use of a long time, but the relatively high cost.
 
Equipment Features:
U-shaped screw conveyor is a kind of screw conveyor, which is suitable for small-scale operation, stable transmission, and can play a good role in the limited conditions of the transmission site. The sealing performance is good, and it has great advantages for occasions where the dust is large and where there are requirements for the environment, which can prevent the generation of dust in the conveying process. However, the U-shaped screw conveyor is not suitable for long-distance transportation. The manufacturing cost is larger than that of the belt conveyor, and it is easy for the fragile materials to be destructed.
