Belt conveyor GUF-P 2000 CA, compact belt conveyor without any interfering contours

For most conveying applications, a compact conveyor frame on the belt conveyor is crucial. Obstructing contours, such as the drive, may protrude and be a little larger, and will mostly be outside the relevant area of the machine. If the entire conveyor is to be installed inside a machine, however, it will usually need to have few or no obstructing contours. In such cases, an internal motor is recommended

The GUF-P 2000 belt conveyor, the most versatile belt conveyor series produced by the mk Technology Group, is now available with a compact and powerful 24 V drum motor. Called the GUF-P 2000 CA, it is absolutely ideal for integrating into systems without much installation space. The ø 53 mm drive roller combined with the 50 mm tall conveyor frame profile produces a conveyor that is extremely flat without any obstructing edges. Along with start/stop control, the control module enables you to set multiple speeds and change the conveying direction.

With a permissible total load of up to 15 kg, the GUF-P 2000 CA is ideal for the majority of conveying tasks in the packaging or plastics industry. The 24 V DC drive also allows for a battery power supply. As a result, the conveyor is also perfect for use as driven load handling equipment for automated guided vehicle (AGV) systems. Furthermore, its compactness and lack of interfering contours means it can be installed on tables in workshops, schools, laboratories and elsewhere. In such environments, the GUF-P 2000 CA can also fulfil technical cleanliness requirements thanks to its clean contours.

Ammeraal Beltech is a world leader in providing complex conveying solutions. The history of the company began with the development of a groundbreaking belt for the Bakery Industry. Today, the company’s products are available in over 150 countries around the globe and new launches are scheduled throughout the year. This time, it conquers the market with Duraclean – a synthetic belt perfect for processing sticky foods in the Bakery & Confectionery Industry and not only.

Bakery and Confectionery Industry: major challenges

Some products require specific treatment, and the whole industry poses particular challenges. Energy bars, snacks, and even ready-to-eat meals need delicate handling as the products are prone to damage. The integrity and quality of goods need to be secured.

Baked foodstuffs are often dense or feature ingredients that leave a residue, such as fillings, fruit, and jams, which may lead to stickiness. If a sticky component gets trapped in the production line, extra time is needed to remove it and clean the conveyor. Not to mention the waste of the product itself. The whole production process is thus slowed down, and most manufacturers in this field value efficiency. They need to process large volumes of goods at a fast pace. However, it’s important to balance speed with quality, ensuring size, taste and presentation are uniform across the batch.

Duraclean – a new level in non-stick belting

Ammeraal Beltech understands Bakery and Confectionery pain points and has created a solution to address them all: Duraclean, a synthetic belt for sticky products.

Its thermoplastic compound blended cover ensures excellent mechanical properties and is suitable for use with belt scrapers and knife edge transfer applications.

 Duraclean – major advantages for your business

Duraclean offers a number of improvements for the bakery and confectionery manufacturers. Excellent product release properties, high abrasion resistance, leading to longer service life, wide working temperature range …just to name a few.

The design of the belt grants users longer belt life and improved hygiene standards. The solution significantly reduces the risk of cross-contamination, is easy to sanitise and compliant with EC 1935/2004 and FDA food safety standards.

The effects of exposure to ozone

Ozone occurs naturally in the upper atmosphere. At high altitude, it acts as a protective shield by absorbing harmful ultraviolet rays. However, at low altitude, the ozone itself becomes a pollutant. Exposure to ozone increases the acidity of carbon black surfaces and causes reactions to take place within the molecular structure of the rubber. This has several consequences such as a surface cracking and a decrease in the tensile strength of the rubber. The actual level of ozone concentrations at ground level, and therefore the level of

exposure, can differ greatly from one location to another depending on geographical and climatic conditions. The general concentration of ozone is from 0 to 6 parts per hundred million parts of air. Coastal areas have particularly high levels of ozone pollution. Ozone also occurs in cities and industrialised areas, when it is formed by the photolysis of nitrogen dioxide from automobile exhaust and industrial discharges, where ozone levels can range from 5 to 25 parts per hundred million parts of air.

Environmental and safety concerns 

Belts that do not operate under shelter are especially prone to surface cracking, which can be extremely detrimental in terms of the performance of the belt and its working life.

Even more significant are the environmental and health and safety consequences of the damage caused by ozone exposure because dust particles from the materials being conveyed penetrate the surface cracks and are then discharged (shaken out) on the return (underside) run of the belt.

At first glance, fine cracks in the surface rubber may not seem to be a major problem but over a period the rubber becomes increasingly brittle. Transversal cracks deepen under the repeated stress of passing over the pulleys and drums and, if the conveyor has a relatively short transition distance, longitudinal cracks can also begin to appear.

Again, surface cracking may not initially seem to be a cause of concern but there are often hidden long-term effects.

One of those hidden effects is that moisture and other fluids seep into the cracks and penetrate through the belt covers

down to the carcass of the belt. If the belt is carrying product such as household waste, grain, wood/waste or biomass then the oils and resins that penetrate through to the carcass will cause the belt to swell and distort very badly.

The effects of ultra violet radiation

Ultraviolet radiation causes chemical reactions to take place within rubber and the rapid decline in the ozone layer in the upper atmosphere over the past several decades is allowing an increasing level of UV radiation to reach the earth’s surface. Ultraviolet light from sunlight and fluorescent lighting accelerates deterioration because it produces photochemical reactions that promote the oxidation of the surface of the rubber resulting in a loss in mechanical strength.

EN/ISO 1431 International standards

To scientifically measure resistance to ozone, samples are placed under tension (20% elongation) inside the ozone testing cabinet and exposed to highly concentrated levels of ozone for a period up to 96 hours. At Dunlop the pass criteria is that the rubber sample does not show any signs of cracking after 96 hours (@ 20°C, 50 pphm and 20% strain) inside the ozone cabinet. Every sample is closely examined for evidence of cracking at two-hourly intervals and the results carefully measured and recorded. As a general rule, based on experience, failure to exceed more than 8 hours under test without surface cracking will most certainly mean that the belt will start to deteriorate in less than 2 years. In many cases, particularly in coastal locations, deterioration will begin within a matter of months.

At Dunlop Conveyor Belting we were amongst the very first to introduce mandatory testing to EN/ISO 1431 international standards. As a direct result, special anti-oxidant additives that act as highly efficient anti-ozonants were introduced into all of our rubber compound recipes to provide protection against the damaging effects of ozone and ultra violet.

Always insist that your belt supplier provides written verification that their belts undergo stringent conditional

Seek advice

As often as not, the quality of a belt (including its ability to resist wear) is reflected in its price. It is always worth the effort to check the original manufacturers specifications very carefully and ask for documented evidence of tested performance compared to the relevant international standard before placing your order.
