Precise and Fast Bagging of Dusty Materials?

Type MP-ZBSZK-20. gross bagging scale. The equipment has a two-stage belt feeder, approx. Pneumatically operated gross bagging scale equipped with a 2 m3 receiving hopper, with a measuring cell and a digital instrument. with a compressor equipped with a pressure switch.

Usage of the scale

• the bagging scale is suitable for dosing soil-moist non-adherent compost and sludge in a coarse-to-fine grade, as well as for their accurate measurement and filling into bags.
• the scale is used for measuring and the amount of weight to be measured (10-20 kg) and the dosing parameters can be freely programmed on the control instrument’s keyboard.
• The scale has a complete structure, according to which it includes the crop receiving hopper (approx. 2m3), the dosing belt, the scale with bag gripper, and the system holding the entire system scaffolding.
• the bagging scale has a bag counter and weight summing function and the so-called it ensures accurate measurements by operating a self-learning program.
• The sludge to be filled must not stick to the feeding belt or the hopper, because this problem affects performance and accuracy.

• Specific weight: ……………………….
• Consistency: similar to potting soil
• Sample: not available

Installation:

• The attached drawing contains the dimensions required for installation. For the continuous and accurate operation of the equipment, the crop must be stored in the receiving hopper of the scale, so that there are always at least 5 bags of crop in the tank.
• A place must be provided for the installation of the scale, where there is no vibration, and it must be fixed in such a way that it does not pick up the vibrations from other moving equipment and structures.
• The installation height of the scale must be chosen such that at least the empty space is the length of the bag must remain + the height of the conveyor belt.

Mode of operation, service

• The bagging machine is in semi-automatic gross operation.
• In the case of gross measurement, the sludge goes directly into the bag and the measurement takes place here after the bag has been placed.
• After switching on the machine, the only task of the operator is to place the empty bags on the filling pipe. The portions are measured and the bags are dropped after filling. The dropped bag is placed on the bag conveyor belt placed under the scale, which continuously transports the bag to the bag seamer or welder, or to the shoulder belt, for palletizing.
• Filled bags can be sealed with a sewing machine or welder, which is usually performed by a second operator.

Weighing technical service:

After putting the scale into operation, it performs the following tasks with the software of the measuring electronics:

• Controls the operation of the coarse-fine belt feeders, the back-fall arc lock and the bag gripper
• The self-learning program of the weighing instrument compares the set and loaded weight values, and then ensures reliable and accurate dosing in case of deviations measurements.
• The electronic scale also displays error messages on its display (e.g. the material does not arrive). All text displays are in Hungarian.

The scale’s measuring and control electronics display the following technical display:

• Measures the current bag weight
• Current bag weight, number of filled bags display
• Performance display (t/h)
• Limit value management (e.g. 150 bag)
