The 2-channel weighing electronic from Hense Wägetechnik multiplies the net weight inside the screw conveyor with the rotation speed of the screw. The flow rate and the cumulative total amount of the conveyed product are visualized on a color graphic display.
Capacity is defined as the weight or volume per hour of a bulk material that can be safely and feasibly conveyed using a screw conveyor. Screw conveyor diameter is determined by multiple factors including capacity.
The calculated torque is less than the maximum allowable torque 15435 lbs.35mm Torque calculation: Torque acting on the screw conveyor is given by the relation = 63025 * motor horse power / N (rpm of the screw) = 63025* 3 / 54 = 3501.0310in =0.54 T = 395.

Screw conveyors are most often integrated in automatic Gain in Weight or Loss in Weight systems. When running Loss of Weight, the screw feeder can be operated either in volumetric mode or on automatic gravimetric mode.
The loss-in-weight system is normally supplied with a standard Rospen metering screw feeder either single or twin screw from 12mm to 250mm dia and output range from 1.0kg/hr to, in excess of 100,000kg/hr.

Loss-In-Weight (LIW) Helix Flexible Screw Conveyors are fully automated dosing systems that allow for batching material. The Integral load cells indicate when volume is within 5 lbs of set maximum by slowing flow. The conveyor will shut down within +/- 1 lb of the maximum volume set point.
The accuracy of a weighing screw conveyor depends on many factors. Firstly, the weight of the product in the screw must be in a sensible ratio to the weight of the screw conveyor itself.
As the conveyor unloads material at maximum feed rate, the load cells transmit loss-of-weight information to the controller which reduces the feed rate to dribble immediately prior to stopping the flexible screw conveyor or rotary airlock valve once the target batch weight has been discharged.

The rotating spiral vane conveys the material while being conveyed, so that the force that the material does not rotate with the screw conveyor blade is the weight of the material itself and the friction resistance of the screw conveyor housing to the material.
Our conveyor scales integrate into any industrial process that needs to weigh items as they pass through. They are ideally suited to checkweighing, straight weighing and weight accumulation operations.
A weigh belt conveyor is generally a slow speed conveyor installed with a single or two idler belt weigher. Weigh Belt Conveyors provide continuous weighing with better accuracy than a belt weigher.
CAPACITY of a screw conveyor is determined volumetrically. If a given weight of product is to be conveyed in a specified time, the loose bulk density of the product must be known to determine the

Flexible screw conveyors, or auger conveyors, are often the lowest cost means of transferring dry bulk solids from one point to another. Gentle Product Handling The rotating flexible screw conveyor spiral, centralized within the conveying tube, gently moves material without degrading it.
The flexible screw conveyor carries the material to an elevated point at the required flow rate. Once the load cells indicate the flow volume is within 2.27 kg (5 lbs.) of set maximum the conveyor is automatically slowed to dribble mode.
