An auger conveyor - or screw conveyor - is a mechanical conveying solution that uses a rotating screw to move bulk materials in a continuous, controlled and safe manner. Its mechanical simplicity contrasts with its great versatility: it is capable of conveying cereals, flours, minerals, biomass, sludge, waste and many other materials, regardless of the distance or orientation required for transport.

DAC Industrial Screw Conveyor Models

At DAC Industrial we manufacture a wide range of screw conveyors, each designed to meet the specific needs of each industry and application:

• SSC - Troughed Conveyor: The most versatile solution for horizontal or slightly inclined conveying of powdered or granular materials.
• SCT - Tubular Conveyor: ideal when the conveyed material must be protected from the outside environment or when space is limited.
• SLC - Screw conveyor with casing: Especially recommended for materials that can be trapped in the central core, such as fibrous or pasty products.
• SLD - Desander Conveyor: Designed to separate and remove suspended solids from liquid streams, widely used in wastewater treatment plants and waste treatment plants.
• SLE - Extractor Conveyor: Designed for the controlled extraction of material from hoppers or tanks, ensuring a stable and adjustable flow.
• SLF - Conveyor with filter: a specific solution for applications where it is necessary to filter and dewater the material during the conveying process.
• SLP - Pressing conveyor: incorporates a progressive compression system that allows to reduce the volume of the conveyed material, which makes it very useful for waste or biomass.
• SLI - Injector conveyor: Designed to introduce materials in a controlled way in specific industrial processes.

For this reason, we would like to share the conclusions of the III Report on the Analysis of University Engineering Studies, presented by INGITE at the beginning of the year, which paints a worrying picture for the future of the profession and, in turn, for the entire Spanish industrial fabric.

The strategic role of engineering

INGITE is the body that brings together the professional associations of the ten branches of engineering in Spain and represents more than 350,000 professionals. Its aim is to promote engineering as a fundamental tool for tackling social, economic and industrial challenges.

From this perspective, the report highlights a profound mismatch between the academic offer and the real needs of the labor market, with direct implications for strategic sectors such as industry.

A drastic decline in engineering vocations

One of the most striking findings of the study is the sustained loss of interest in engineering studies. The number of students enrolled has fallen by 33 % since the 2002-2003 academic year. Whereas in 2002 engineering accounted for 24 % of university enrollments, in the 2024-2025 academic year this figure stands at 16.98 %.

This decline jeopardizes generational succession at a time when industry needs more technical profiles than ever.

Few graduates to meet the challenges of the future

The situation is even more critical if we look at the number of graduates. Only 7.54 % of all university graduates have an engineering degree. In 2006, this proportion was close to 20 %.

According to INGITE, this volume is clearly insufficient to meet the challenges of energy transition, digitalization and industrial transformation, processes that require a high level of technical competence.

A very high dropout rate

In addition to the lack of vocations, there is another worrying factor: around 50 % of students who start an engineering degree do not complete it.

This dropout rate further aggravates the shortage of qualified professionals and highlights the need to review both academic approaches and the orientation of studies.

The explosion of non-qualifying degrees

Currently, 53% of undergraduate engineering degrees do not allow the practice of the regulated profession. In the last decade, this type of degree has grown by 59.4 %.

This means that many graduates cannot assume professional responsibilities, such as approving projects or supervising construction work, without completing additional training.

This pattern has direct consequences for people:

• There are more than 200 000 people affected -between graduates and students- who have completed non-enabling degrees.
• Many are forced to invest more time and financial resources in enabling master's degrees in order to be able to practice fully, which delays their entry into the labor market.

According to INGITE, this situation generates frustration and discourages new vocations.

The positive aspect: greater female presence

The report also includes some positive indicators:

• The presence of women in engineering studies has increased by 36.6 % in the last ten years.
• They now represent 23% of the student body.
• They also have a higher graduation rate (46.9 %) than men (39.4 %).

Nevertheless, significant regional imbalances persist. While some communities are increasing enrollments -often driven by non-accredited degrees- others with a long industrial tradition, such as Asturias, Castilla y León or Extremadura, are seeing enrollments in accredited degrees fall significantly.

A structural solution: an Engineering Law

As a strategic conclusion, INGITE calls for the urgent need for an Engineering Law that:

• Unifies the professional framework.
• Protect the name of engineering by demanding compliance with European standards.
• Eliminate the current confusion between academic qualifications and professional attributions.

According to the organization, this is an essential condition to guarantee the future of the profession and ensure that the industry has the necessary technical talent.

At DAC Industrial, we share this concern. The development of our own efficient and sustainable industrial solutions is only possible with personnel who have the appropriate training, aligned with the real needs of the sector.

We believe that strengthening the link between the company, training and industrial reality is key to ensure a competitive future.

See the main findings of the study

This study offers a fairly clear view of how the metallurgical sector business community perceives its activity in terms of turnover, employment, exports and operating expenses. A summary is given below:

1. Turnover growth above expectations

The metal’s sector is forecasting a 61.4% increase in turnover despite external pressures. This forecast, according to the Industry Talks portal, shows that companies maintain a high level of confidence in demand and in the sector's production capacity.

2. Positive employment trend

Metalworking companies continue to show a favourable outlook for employment. The sector expects to maintain and even improve employment levels in 2026, despite economic uncertainty and rising logistics, energy and raw material costs.

This resilience of the labour market confirms the strategic importance of the metallurgical sector within industrial activity.

3. Weakness of the foreign sector and fall in exports

One of the weaknesses highlighted by the report is the performance of the foreign sector. Exports closed 2025 declining, with an index of 43.1 points. Although a slight improvement is expected (to 46.1 points), the trend will remain negative during the first months of the year.

These figures confirm that lower international demand and global competition continue to limit the export capacity of companies in the sector.

4. Rising costs: the most immediate challenge

Despite the expected growth in turnover, metallurgical companies continue to face a significant increase in costs, as CONFEMETAL points out in its report.

According to sources consulted by the entity (under whose umbrella are grouped up to 78 associations representing more than 220,000 companies), the most significant increases affect energy, transport, raw materials and the general logistics of the production process.

This pressure is one of the factors most affecting profitability and could limit growth margins in 2026.

A combination of cautiousness and cautious optimism

All these indicators paint a picture in which optimism, in terms of turnover and employment, is mixed with caution in the face of falling exports and rising costs.

All this indicates that the sector remains resilient, but must focus on achieving greater efficiency, digitizing and adopting competitive strategies to maintain its pace of growth in an uncertain global context.

If you are considering incorporating new equipment for your plant, this article will serve as a starting point to make informed decisions and avoid mistakes that you may regret later.

1. Define your real needs

Before thinking about specific brands or models, it is essential that you are clear about what need you are looking to solve. Do you want to increase production capacity? Reduce downtime? Automate manual processes?

At the same time, you must always keep in mind your activity, what components you manufacture or process, what quality standards you must meet, the budget and/or the space you have available?

The more precise you are in defining your requirements, the easier it will be to find a solution that fits them perfectly.

At DAC Industrial we help you to analyse your current situation and define an improvement plan. Discover our work methodology.

2. Evaluate the working environment

The machinery must adapt to the physical and operating environment in which it will operate. Factors such as temperature, humidity, type of materials to be processed or available space can influence the choice.

In addition, it is important to consider compatibility with other existing equipment.

3. Consider maintenance

An efficient machine is not only one that produces more, but also one that is easily maintained. Preventive maintenance is key to avoid breakdowns and prolong the life of the equipment.

Make sure that the chosen machinery has good access to spare parts, technical support and ease of maintenance.

At DAC Industrial we have an expert team to perform maintenance and repair tasks for our industrial solutions.

4. Value the total cost, not just the purchase price.

The initial price is only part of the cost. You must also consider energy consumption, maintenance costs, personnel training and long-term amortization.

A more expensive machine may be more cost-effective if it offers higher efficiency and less downtime.
