Screw Conveyor Features. 7 inch diameter screw conveyor capacity 9 ton per hour; 9.5 inch diameter screw conveyor capacity 15 ton per hour
Get PriceThe capacity of a screw conveyor depends on the screw diameter, screw pitch, speed of the screw and the loading efficiency of the cross sectional area of the screw. The capacity of a screw conveyor with a continuous screw: Q= V * ρ. Q = 60 * (π/4) * D2 * S * n * ψ * ρ * C Where, screw conveyor calculations. Q = capacity of a screw conveyor
Get PriceCalculation of Conveyor Speed. Conveyor Speed can be most conveniently calculated, by use of the nomographs supplied on pages. To use this nomograph – first locate the two known values (screw diameter, and required capacity, in cu. ft. per hour), then with a straight edge connect these two points.

Get PriceWhat is screw conveyor? Screw conveyor is a kind of conveying equipment that widely applied in the chemical industry, construction industry, and grain industry for transporting powder, granular and small block materials. Its optimal operating environment temperature is 20~50℃, and the conveying length is generally less than 40m, the longest is not more than 70m,
Get PriceScrew Conveyor Capacity Engineering Guide. A 16inch diameter screw conveyor will convey 2496 cubic feet per hour at the maximum recommended speed of 80rpm The actual screw conveyor speed is calculated by dividing the Selection Capacity by the capacity at 1rpm 1873312 60rpm. More Details >

Get PriceAfter the diameter and RPM of the screw conveyor are known the motor horse power (HP) has to be determined. The HP is the force required to move the product over the length of the conveyor in a given amount of time. Since screw conveyors tend to tumble material, this calculation also has to account for this tumbling of the material while it is moving along the screw conveyor. Most screw
Get PriceBesides conveyor capacity, the size of a screw conveyor also depends on the size and proportion of material lumps to be handled. Material lump size is given by is the maximum dimensions of the material in its transverse cross-section. Accordingly, long dimension or lengths determine the lump size. Considerations are made for the characteristics of the handled material lump. Some materials may

Get PriceThe size of screw conveyor depends on two factors 1. The capacity of the conveyor 2. The lump size of the material to be conveyed (Maximum dimensions of the particle) Usually there are three ranges of lump sizes which are considered for selection of screw size. These are: · A mixture of lumps and fines in which not more than 10% are lumps ranging from maximum size
Get PriceSelect the size for your capacity using the smallest diameter conveyor that is below the maximum recommended speed. After size is determined then exact conveyor speed is determined by dividing the required capacity in cubic feet per hour by cubic feet per hour at 1 revolution per minute. Note: If handling a material with hard lumps [lumps that will not break up in the Screw Conveyor] refer
