The liquid dosing system mainly consists of a storage system in accordance with MIE APQ (0 to 10) depending on the product. This storage is equipped with a filling system from the product container (from IBC, tank, etc.), a measurement system (cells, radar, maximum levels), and, if necessary, may have an agitation, heating, or cooling system.

Subsequently, a process delivery system is available. Depending on the required precision, the system will have a pumping system which may be controlled by measurement in the storage tank (by discount), online flow meter, or reception hopper with precision weighing.

The type of pumping system will depend on the product to be dosed, as well as the materials and treatments for the system piping.

Liquid storage and dosing systems enable greater management of raw materials, as well as greater automation of the production process. One of the main advantages of additive dosing systems is the ability to ensure uniform volume of work for dosing, reduction of errors in the process, and improvement in purchasing management due to its automation.

At GMdix Process Engineering, we offer solutions for both volumetric and gravimetric dosing by weight loss or gain, for both principal or secondary products, continuous or discrete (in batches).

We have a wide variety of hoppers, through screws, rotary valves, belts, vibrating channels, accessories, and control systems to adapt to the needs of our clients. We cover a wide variety of grain or powder materials, as well as low and high dosing rates.

As manufacturers of this industrial equipment, we are able to adapt to the requirements of our clients.

Types of dosing systems:

Volumetric dosing:

The flow of material is regulated according to the speed of the dosing element, usually by a screw, which must be suitably selected to provide the required flow rate with the required dosing precision.

Gravimetric dosing:

Material flow is continuously regulated based on weight, thus variations in apparent density, or grain size, do not affect the accuracy of the process.

All the components of our equipment are selected based on the characteristics of the products to be dosed, while always complying with dosing precision, ease of use, and longevity parameters.

All our gravimetric feeders are supplied with state-of-the-art microprocessors touch controls with easy-to-use operator interfaces.

Construction materials may be very different depending on requirements. These may be carbon steel, stainless steel, etc. Different non-stick surface finishes and abrasion resistant coatings are also available.

Depending on the products to be handled, we offer equipment with internal agitators for materials with poor fluidity.

We also offer solutions for easy disassembly and cleaning, which enable quick product changes.

The maximum allowable temperature for this equipment is 80ºC-250ºC. For higher temperatures it is necessary to consult GMdix.

Options: These may be configured with multiple options: bag feed hopper, Big-Bag loading, quick-close valves at the outlet, etc. Also available for installations in classified areas (ATEX areas).

We have a testing laboratory to analyse the client’s product so as to select the best design and suggest handling and transport conditions that enable process optimisation.

The hopper is a container similar to a large funnel into which the product is loaded from the top. It has capacity to store a sufficient quantity to carry out uniform and efficient channelling thanks to the deep slope which allows complete emptying of the product while preventing loss. All types of sensors to monitor its operation are common additions for precise control over its usefulness.

There are infinite variations given that our industrial equipment is adapted to each client’s needs. Hoppers of all types of capacities and sizes may be manufactured, both in carbon steel and stainless steel, with specific finishes and surface treatments for these materials. Likewise, pressure, jacketed, and heat-insulated hoppers are also available; all of them may be combined.

This technology is a system that enables powder materials to be conveyed suspended on an air bed.

Air enters the airslide through threaded sleeves and is distributed over the entire surface. Once sufficient internal pressure is achieved, the air exits through the porous fabric, starting the process of fluidising the material. Fluidisation allows particles to be separated by surrounding them with air bubbles and keeping them loose.

Finally, the material is conveyed due to the slope of the airslide between 4º and 10º.

Multi-way diverters consist of a board with different reception and conveying channels to the appropriate destination through an elbow-shaped fitting.

Melters are mainly comprised of a storage container, which may have either a cylindrical or square geometry and may be constructed of different materials, primarily stainless or carbon steel.

These have a work area in the upper part, which is used as a support for the product to be subsequently poured onto a grate located in the upper part and heated by hot water or steam. This grate is the element that melts the product by conduction, which then precipitates through the grate into the container.

In order to preserve the product state, the container is equipped with a water or steam heating jacket, keeping the melted product in a liquid state until incorporation.

Finally, this industrial equipment incorporates an agitation system to prevent phase separation while enhancing homogenisation of product temperatures.

Melters enable melting of raw materials prior to incorporation into the process, making it possible to not only reduce the time spent on process mixtures but also to improve them as well. Additionally, melters are widely used in surplus recovery processes (products to be reprocessed).

Tanks receive the product through one or more inlets to be stored. The product will then be conveyed to its next destination. The objective of this application is to maintain the product with the required characteristics. Therefore, element properties such as temperature, pressure, homogeneity (in the case of a mixture of immiscible products) are often taken into account. In order to ensure that these objectives are met, tanks are equipped with all types of sensors to monitor their ideal operation.

There are infinite variations given that our equipment is adapted to each client’s needs. Tanks with a capacity of 5 litres or more may be manufactured, both in carbon steel and stainless steel, with specific finishes and surface treatments for these materials. Likewise, pressure, jacketed, and heat-insulated tanks are also available, with agitators or recirculation; all of them may be combined.

The operation of a conveyor belt consists of the continuous movement of a belt mounted on platforms with variable dimensions and which may have different types of accessories (side guards, stops, diverters, railings, wheels, and other types of pneumatic or mechanical accessories). Speed and load capacity will depend both on the characteristics of the material to be conveyed (dust, fine grain, packages, etc.) and the type of conveyor belt.

Operation using a Y to which two valves are mounted to select the desired path by opening one valve and closing the other. It is comprised of a Y-shaped pipe and 2 sleeve or ball valves.

There are different formats of diverter valves. These may be constructed in-house or commercially available; the latter may use rotary drums to eliminate the valves. Measurements vary according to the pipe to be used and if they are treated. They may be coated internally with anti-wear materials to minimise abrasion.
