Shaftless screw conveyors for bulk solids transport
Sinfimasa specializes in bulk solids conveying. Below you find technical advantages and application examples of shaftless screw conveyors In the transport of bulk materials, the design and configuration of the mechanical conveyor is crucial for the efficiency and economy of the process. One of the most interesting pieces of equipment in this area is the shaftless screw conveyors, also known as Archimedes’ screws without a shaft. Although commonly used in sludge transport, their application goes beyond this. In this article, we will explore when and why a shaftless screw conveyor should be used to transport bulk solids. What is a Shaftless Screw Conveyor? A shaftless screw conveyor is a type of conveyor that, unlike traditional screw conveyors, does not have a central shaft. It consists of a helix that rotates within a tube or trough, moving material along the conveyor. Technical Advantages * Lower Risk of Clogging; With no central shaft, there is less risk of material getting stuck or accumulating around the shaft, which is especially useful for sticky or wet materials. * Better Handling of

Tips for effective screw conveyor maintenance
Proper maintenance of a screw conveyor is essential to ensure its efficient operation, prolong its lifespan, and avoid costly repairs or replacements. How to check and maintain effectively. A screw conveyor, also known as an auger conveyor, is a machine that uses a helical screw to move bulk products from one point to another. Proper maintenance of a screw conveyor is essential to ensure its efficient operation, prolong its lifespan, and avoid costly repairs or replacements. Sensitive points in a screw conveyor # Bearings: These parts allow the screw to rotate without friction. It’s crucial to check them regularly for signs of wear or damage. # Helical Screw: This is the main part of the conveyor. It should be inspected for deformations or excessive wear. # Tube or Trough: This is the container where the screw is located. It should be free of obstructions and damage. # Seals: They prevent material from escaping and protect against the entry of contaminants. They should be checked and replaced if necessary. Parts to replace periodically # Drive Shaft Bearings - Inspection and greasing; Frequency: Every 1000 hours or every three months. Regular

Sinfimasa helps choose optimal vertical conveying for your application
Operating temperature, granularity, and other characteristics determine what the best option is for a bulk solids elevator. This item describes different types of bucket elevators: chain or belt. Chain or Belt Bucket Elevator Typically, in the industry and handling of bulk solid products, belt-anchored bucket elevators are used for vertical material lifting due to their higher performance in terms of load capacity and lifting speed. However, a chain bucket elevator emerges as a robust and reliable solution for lifting materials under certain specific conditions. Comparing them with the former, we observe significant differences that influence the implementation decision according to the needs of each project. Heavy-Duty applications Chain bucket elevators stand out for their ability to handle bulk materials of large size, high density, abrasiveness, and under high-temperature conditions. This type of elevator uses robust chains as a means of support and traction for the buckets, which gives it superior resistance to wear and slippage. This feature makes them ideal for applications where materials such as minerals, coal, and chemicals need to be transported

Preventing wear of conveyors for abrasive bulk goods
Preventing wear of conveyors for abrasive bulk goods
To prevent abrasive wear, it is necessary to use abrasion-resistant industrial coatings with good resistance to the (hardest and sharpest) particles in the bulk material being transported. The simplest solution is to apply a hard coating or lining to the surface of the parts of the conveyor in contact with the product. This protective coating should have a greater hardness than the particles causing the wear. A second possibility is to apply reinforced coatings with a better chemical composition, giving phases greater functionality and more protection. A third possibility is to treat the base metal, making it more resistant. Wear protection for bucket elevators For a bucket elevator, the buckets should be reinforced at the edges with an anti-wear steel plate, as this is the area most affected by wear. Wear protection for screw conveyors In screw conveyors, on the other hand, the entire spiral and shaft should be made of anti-wear steel. For this purpose

Which bulk material conveyor for which situation?
Chain and screw conveyors versus belt conveyors. Sinfimasa manufactures chain and screw conveyors specifically for each customer and project. Which bulk material conveyor for which situation? Chain and screw conveyors versus belt conveyors There are several alternatives for conveying bulk materials. The most important of these are screw conveyors, belt conveyors and chain conveyors. Conveyors for bulk material should always be tailored to the situation: the movement path and the characteristics of the specific bulk material. Which type of conveyor is best for each situation? At Sinfimasa, we always say that the most important factor determining the choice of conveyor type is the product to be transported. Before the engineer defines the system, the properties of the product and conditions must be characterised. To mention are: the bulk density, grain size, abrasiveness, corrosivity, the temperature at which it will be transported, the power required, the degree of clumping, hygroscopicity, etc... Depending on the product and the configuration of the process or plant, one device will be better than

Sinfimasa bucket elevators and screw conveyors for lead oxide  Confined horizontal and vertical transport of lead oxide with a temperature of 110°C, a toxic and polluting material.
Sinfimasa bucket elevators and screw conveyors for lead oxide
Confined horizontal and vertical transport of lead oxide with a temperature of 110°C, a toxic and polluting material. Lead oxide or lead dioxide is an odorless brown powder or crystal. It is used in the electrodes of lead-acid accumulator batteries and in the paint, rubber and ceramics industries. In this success story, our client is a multinational lead-acid battery manufacturer that needed to transport and elevate lead oxide with an average temperature of 110°C for a new manufacturing line. Lead oxide is characterized by a high density and in this case, it is transported with a fine granulometry in powder form. In addition to its toxicity and polluting capacity, it requires that the machinery that transports it has an adequate sealing to avoid material leaks and an adequate dimensioning to ensure its correct operation in case of unexpected stoppages. Lead oxide bucket elevators To meet the requirements of the plant’s engineers, Sinfimasa designed and manufactured a belt bucket elevator taking into account the abrasion, temperature and tension requirements, so a top brand
