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 an alloyed, hardened and tempered anti-wear steel is used , which is characterised by its resistance to abrasion and impact, as well as its high mechanical strength, good formability and weldability.

Wear protection for chain conveyors

In the case of chain conveyors, the three main points of wear are: 1) the carriers, 2) the central chain or chains that drag the blades, and 3) the structure or body of the conveyor itself, mainly the areas where the chain drags, as well as the bottom where the material is dragged and the sliding parts of the material at the inlet(s) and outlet(s).

Sinfimasa
Experience and Commitment The main business of Sinfines y Maquinaria S.A. (Sinfimasa) is to understand the customer and design and manufacture conveyors according to project requirements and the specifications of the solid material to be handled. At our facilities in Guissona (Spain), we have our own engineering department with over 35 years’ experience, where we design machines that meet our customers’ technical specifications and make our commitment to their engineering project. We offer solutions for conveying and lifting bulk solids with uncompromising quality and precision, and we ensure equipment reliability in every situation in the processing plant. Safe, Robust, Reliable In our production plant we manufacture products with all types of finishes as required: pickled and passivated, electro-polished, lacquered, sandblasted and food-grade, etc. We work with different materials such as carbon steel, stainless steel and anti-wear steel. We use high quality and universally available components such as SEW gearmotors or SKF bearings. Our suppliers are also key to our success and we make a commitment to them. We have a test bench where, based on product samples from our customers, we research the best solution for the requirements of each project. We are committed to our customers and engineering companies to offer machines with guaranteed reliability. Sinfimasa has welding procedures and welders approved according to ASME Section IX (QW-484). We use an automated welding system to ensure that the entire length of the conveyors are welded evenly and are free from voids. At Sinfimasa we are rigorous and demanding, with numerous references in several countries on all five continents as our guarantee. Please ask us for more information as you require. Consult us about your project on no obligation. We will make you a reliable technical proposal that is 100% adapted to your requirements.

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

Chain conveyors for transport and elevation of Solid Recovered Fuel
Sinfimasa designed three chain conveyors for the transport of SRF. Sectorization of two fire zones was important, so one of the conveyors was equipped with firewall slide gates. Solid Recovered Fuel (SRF) is a fuel prepared from non-hazardous waste, and used for energy recovery in incineration and co-incineration plants. It consists of small fractions of waste with a high calorific value. This makes it also suitable for use in cement kiln installations. Our client is a non-hazardous waste valorisation plant, and needed to build a conveying line to deliver different types of SRF into storage boxes after shredding, separation and classification process. The required output was 150 m3/h. Transport in 3 steps To solve this need, Sinfimasa designed three chain conveyors; the first one would transport the SRF at a horizontal distance of about 10m and would elevate it to a height of 8m. The second conveyor is positioned horizontally over a distance of 4,7 m. An important function of this conveyor is to ensure the sectorization of two fire zones, so it was equipped with firewall slide gates. A third conveyor was designed and manufactured

Sinfimasa supplies several screws for sugar in ATEX design
Sinfimasa supplies several screws for sugar in ATEX design
A major manufacturer of soft drinks, both sweetened and light and zero, required several screw conveyors for conveying sugar. The challenge in this case was that the screws would be located in an ATEX 22 (3D) zone and had to have a food-grade finish according to FDA regulations. The project also included several extraction screws for unloading silos and big-bags, and conveyor screws for transport with throughputs ranging from 9 to 36 tons per hour. Some of these screw conveyors would be mounted under inclinations of up to 35º. The design of the screws therefore had to take into account the function of each conveyor. The pitch, power and speed of the drives were calculated specifically for each screw. Since the sugar was very fine, a mechanical air sealing system was chosen to close and seal the conveyors. In addition, hygienic production criteria were considered in the design to reduce or eliminate the risk of the screw conveyor being a source of contamination
