how to calculate submerged drag chain conveyor. Dragon-Flite Drag Conveyor Horsepower Calculation . Eng. Guide Index The Dragon-Flite conveyor is an efficient, high performance alternative to conventional means of material handling. Because the material is moved En-Masse, horsepower requirements can be as much as half of that of alternative ...

The SSC is a heavy duty dual drag flight chain conveyor. The conveyor is submerged in a water trough below the furnace which quenches hot bottom ash as it falls from the combustion chamber. The bottom ash is then dewatered as it travels up the inclined section before it discharges. Double roll crushers can be used for

Chain Conveyors Practical Calculations (Metric and US Systems) Jurandir Primo, PE ... Calculate the driving power of a Drag Roller Chain Conveyor, commonly used in Sugar Plants considering the following sketch below: ... Calculate the driving chain conveyor …

Chain calculations Conveyor chain calculations Capacity in kg per hour (Q) Q = A x v x 3600 sec. Q = capacity in m3 per hour A = trough width x layer height in m2 v = chain speed in m per sec Conveyor chain calculations Material weight on the chain in kg (mass1) tons per hour x distance in meters v x 3,6

DRAG CONVEYORS Riley builds drag conveyors for performance and endurance under the roughest conditions. Engineered for efficiency and reliability, our conveyors offer key features that extend life and increase productivity.

Submerged chain conveyors are an ideal solution for pulp and paper mills, waste to energy facilities or coal fired electric power plants. They are able to move 2.4 m to 3.7 m (8 to 12 feet) on up to a 35 degree incline to dewater material efficiently.

ProcessBarron bottom ash submerged drag conveyors feature special water-tight bearings and heavy duty welded chains that reduce stretching common with dual strand submerged conveyors. The submerged ash conveyor systems provide an air tight seal while still allowing ash and other materials to be removed from the boiler or furnace system.

May 06, 2013· Calculating Required Horsepower For a Horizontal Drag Conveyor (En-Masse Conveyor): There are several ways to calculate horsepower for a drag chain conveyor in a grain handling application, however, I have found this shortcut for figuring horsepower for a horizontal drag conveyor to be one of the easiest to use.

Chain conveyors can be configured to meet your process specifications. They are engineered to keep your capital costs low and operating and maintenance expenses to a minimum. 's chain conveyors offering consists of two different types of equipment, drag chain conveyors and submerged chain conveyors. Both chain conveyor types are commonly ...

Move material efficiently with Hapman drag conveyors and the industry's most durable chain. Hapman drag conveyors move material over distances ranging from 20 to 200 feet or more. These conveying systems are equipped with the industry's most durable chain, built with an exclusive drop-forged, case-hardened formula that produces a hard exterior coupled with a …

The Horsepower (HP) requirements of a Dragon-Flite conveyor can be calculated as the sum of the three contributing factors to the HP requirements. The total HP requirement is the sum of the HP to move the chain/flights and sprockets called the "Empty HP" + the HP to move the material in the conveyor called the "Live HP" + the HP to lift the ...

As a specialist in the field of conveyor technology, Bechtel can also help you with design questions of chain conveyors. Download PDF chain calculations We provide you with the basic calculations for the determination of chain speed, capacity per hour, weight of the material to be conveyed, as well as the calculation of the required power.

Jun 12, 2012· Example: Driving a chain conveyor with a gear motor and VFD ... For example, simply calculating the total resistance that the motor has to overcome involves the weight and friction of the conveyor itself carrying the load, additional friction when a box hits the stop, plus the efficiency of the gear unit itself attached to the motor. ...

CALCULATION Required data for chain calculation Required operation data Please add a sketch of the conveyor layout. Please describe operation conditions (e.g.abrasive conditions,environmental conditions,special operation requirements) in detail. Please describe product features in detail,add drawings/sketches. Replacement of chain/belts

Remove chain lengths as required to maintain proper chain sag. If the sag is too long, shut off your conveyor, and follow Lockout-Tagout (LOTO) procedures. Remove the pin from one chain link near the drive sprocket so the chain can be supported. Pull the overlapping ends of the chain hand-tight to determine how many lengths can be removed.

Technical Page 2 HORSEPOWER CALCULATIONS The Basic Principles "Horsepower" is a measure devised by 19th century manufacturers of steam engines (literally "engineers") to compare the work performed by their machines with the amount more traditionally achieved using horses and pit ponies.

Drag Chain Conveyor Systems. ProcessBarron's inclined drag conveyors are ideal conveying mechanisms when a change in elevation is required. Available with single or multiple chain strands, drag chain conveyors are designed to pull materials like coal, wood, TDF, lime and other materials vertically while still working to maintain particle integrity.
