BULK AND LIQUID PRODUCT DOSING AND PACKAGING EQUIPMENT

We produce and install bagging of bulk materials in bags of 50–60 kg equipment with a capacity up to 10 t/ h, made of stainless steel or black steel sheet.

Dosing-bagging equipment in sacks from 5 to 60 kg

 1. Characteristics of the mechanism:

  • especially fast dosage,
  • doses the products of various fraction: flour, fertilizer, grains, granules,
  • a product is not mechanically damaged during dosage;
  • change of the mechanism’s parameters according to the user’s need;
  • the possibility to reduce the dosage error to a minimum value;
  • setting of the dispenser in Lithuanian,
  • the possibility to program the mechanism for 10 different products.

2. The bagging equipment consists of:

  • dispensing high speed grab controlled by the controller,
  • stationary automatic sack sewing machine or manual sewing machine.

3. Other necessary accessories:

  • The packaging apparatus requires: 220 V, 2 kW, compressed air 3-6 bars, 100 l/min.
  • Stationary sewing machine – 400 V; 1.1 kW.
  • Belt conveyor for sacks 400V; 1.1 kW.
  • Manual sewing machine 220 V, 0.75 kW.
  • The dosing device screwed with a flange of Ø 250 mm to the container of raw material at a height of 2 m (if a belt conveyor for sacks is not used, the suspension height can be reduced to 1.7 m).

4. Control menu

Control and configuration of the apparatus is performed directly by touching the active sectors on the touch screen.

 

Big bag dosing equipment

The dispenser is designed for weighing-packing of bulk products in big bags from 200 kg to 1000 kg.

1. Characteristics of the mechanism:

  • especially fast dosage,
  • doses the products of various fraction: flour, fertilizer, grains, granules,
  • change of the mechanism’s parameters according to the user’s needs;
  • the possibility to reduce the dosage error to a minimum value;
  • setting of the dispenser in Lithuanian.

2. The mechanism consists of

  • microprocessor bunker scales with control unit;
  • dosing bulk product transporter with loading hopper;
  • big bag inflation system;
  • transporter with big bags filled (contains 4 big bags).

The weighing device, according to its construction, is installed under the product container or the raw material transportation system (transporter, shovel elevator, and etc.). In order to maintain a constant product flow, and at the same time to ensure the mechanism’s stable performance, it is recommended to mount the device under the intermediate container, which is equipped with level sensors ensuring a smooth flow of the product.

The automation and control cabinet is mounted at a distance of extended arm from the operator’s workstation, and the connecting cables are laid in a surface assembly.

3. Three-phase electric power supply is necessary for operation, and if the flow is dosed by a pneumatic valve – compressed air.

Weighing-dosing range: 200–1500 kg.

Accuracy: <0.2% *

Quick-acting: 12-18 s *

Power supply voltage: 380-415 VAC

Network frequency: 50 Hz

Pressure in air inlet: 4-6 bars

* These parameters are variable and directly dependent on the task and product selected by user, and inseparable from qualification of the service personnel. In case of bulk and a smaller fraction product, a precision error can be reduced to ± 100 g for any weighted quantity and product.

Micro additive dosing equipment

 DESCRIPTION OF TECHNOLOGICAL PROCESS

The bulk product dispenser is intended for dosing-mixing of individual components into a common environment or basic product. The weighing and dosing process is controlled by a programmable logic controller. The latter device ensures precise weighing and even distribution of the components to be inserted into the product.

The dispenser can simultaneously dose-weigh up to x separate components. For continuous work, each product’s container holds up to x kg of the product. Dosage is performed according to the chosen algorithm. Each product is selected on demand; its output is controlled by the controller.

The main options of the dispenser’s operation:

  • the dose (output) of each component is regulated;
  • the succession of each component is selected;
  • adjustable feed rate of the inserted product;
  • indication of the amount of raw material;
  • indication of malfunctions;
  • the ability to connect the dispenser to the overall production management process.

A dispenser containing, for instance, 4 different raw material containers enables insertion of four different components into the main product. Each container is numbered and is intended to contain a separate component.

The principles of the dispenser’s operation:

  • When raw material containers are filled, the controller’s display shows the actual amount of raw material contained in a specific container.
  • With the help of the buttons on the screen it is available to select which components will be inserted. In this case, this is possible, regardless of the succession. (i. e. only components 1 and 4 can be inserted.) Select the desired combination.
  • After determining the components’ composition (selecting the required components), the controller automatically selects the weighing speed. The controller performs this action by evaluating the outlet of the components inserted into the total mass. This is especially important, thus such combination is chosen by which the mixing sequence is chosen, that the components are blended as follows: by the forthcoming components’ yield, their insertion speed is automatically selected, which means that all selected components will be mixed into a common environment over the same time period.
    Here, after evaluations of doses, a smaller dose is inserted into a larger dose, and the total insertion rate is insertion rate of the largest dose. A component of smaller amount is inserted into a larger amount of component, what is necessary for achievement of a good, even distribution and mixing.Taking into account that the larger quantity is a priority quantity, all other components are inserted so that their insertion time does not exceed one single insertion time of the larger dose of the same component. The dispenser can be connected to a common system with production management processes. Default connection ETHERNET and MODBUS protocols are provided for this purpose. On the controller’s screen, the amount of components’ residue is continuously displayed, and in the case of incompleteness of the next load, the controller shows the shortcoming and stops the process. The display shows which component is missing.
