Description
The weight belt batcher of continuous operation SWEDA DWL (feeder) is designed for continuous batching with a given capacity of bulk and lumpy materials.
Usability:
– high accuracy (not worse than ± 0.5%);
– the presence of a device for screw and load belt tension;
– device for automatic centering of the belt;
– availability of a device for cleaning the outer and inner surfaces of the belt;
– automatic adjustment of scrapers as they wear out;
– rear drum cleaning device;
– the presence of a casing with a branch pipe for the aspiration system;
– needle gate, allowing complete overlap of material supply;
– loading neck with belt protection against abrasion;
– special jointless belt with the possibility of quick replacement;
– complete set with a vibrating funnel for low-flow materials;
– thermal protection of the engine against overheating;
– belt break sensor;
– detailed documentation for mounting and operation.
Ample opportunities:
– the width of the conveyor belt is from 650 mm to 1400 mm;
– capacity range from 3 to 630 t/h;
– conveyor length from 2,5 to 8 m;
– the possibility of using materials with temperatures up to 200 °С;
– automatic maintenance of the specified capacity of the batcher;
– control of the batcher from a remote display, an external computer of the batching unit;
– diagnostics of failures of batchers elements, indication of the cause of failure on the control panel;
– the presence of a non-volatile log of events and results (hourly, shift, etc.);
– data transmission on RS-485 or RS-232 (ModBus protocol).
High reliability:
– robust construction of the conveyor;
– the use of components and main units (gear motor, frequency converter, electronic components) from leading foreign manufacturers.

Principle of operation:
The material to be batched enters the conveyor belt from the feed hopper through the gate and the feed neck. The neck with an adjusting gate forms the height of the material layer on the belt. The conveyor is driven by a geared motor by using a drive drum.
The weighing instrument converts the load on the belt into a proportional electrical signal. The belt speed sensor is connected to the axis of the driven drum. The signals from the weighing device and the belt speed sensor are fed to the weight processor PW-310, in which the digital transformation and processing of these signals is carried out. According to the processing results, the corresponding output current signal (4-20) mA is generated, which sets the frequency of the private inverter and, therefore, changes the rotation speed of the geared motor so that the batcher capacity is equal to the specified one.
The weight processor can exchange data with additional external devices (personal computer, remote display) on two buses of the standard RS-485 interface.
