Gravimetric systems

have specialised knowledge in the design of sophisticated integrated gravimetric batching systems for the continuous batching of materials in any amounts from micro - batches to large quantities.
Gravimetric batching systems are used in all processes where precise and consistent feeding of the production plant is required in order to obtain high quality products.
Integration with control systems permits, through precise and costant control of flow rates, production optimisation by improving the dispersion and homogenisation of the products and eliminating waste and down - time.

batching machines are used in various fields of application each with its own specific requirements, and particularly in the plastic, metal, food and pharmaceutical industries.
AUTOMATION AND PROCESS REGULATION
The system allows a constant flow rate to be maintained and number of products to be mixed by way of regulated batching.
Recipes with their respective control parameters can be called up, edited and put into production from a series of screen pages. The productivity of the system is constantly monitored.
Printouts are provided of any anomalous events and alarm conditions that may arise.

SYSTEM START - UP
Production can be started with the call up of recipe parameters stored in memory or with the entering of a new recipe in "automatic start"," immediate start"or"manual" mode.
MODIFYING SETTINGS
From the settings page the operator can assign values to the variables (voltages) for dosing units which are not included in the recipes.
BATCHING
The system features independent loading of material into the hopper.

MODIFICATIONS DURING OPERATION:
1) Modification of global flow rate parameters in the process control page with proportional adjustment of individual flow rates. Modification of the flow rate percentages of the individual components with automatic adjustment of the absolute value.
2) Batch programming. From this page the operator can vary all the modifiable parameters. The parameters assume the new values permanently with immediate effect, even during operation.
3) Manual control page. In manual mode the operator can give pushbutton commands to start or stop all the batching units, modify variable settings and open valves.
OPERATIONS
The following operations can be performed: calibration, date and time setting (for recording events), modification of parameters relative to the acquisition of production data, system configuration and various utility functions.
STOP COMMAND
From the control page the operator can set machine shut - down to "end of process" or "temporary stop" modes. An alarm condition, such as the tripping of a thermal cutout, a blocked valve, lack of material in the hopper, flow rate out of tolerance range, etc..., causes the machine to stop automatically in "temporary stop" condition.
PRODUCTION REPORT
For each production cycle, report sheets are draw up for test at normal operating speed and transitory phases, and the number of rejects as a percentage of total production.
