Produttore e fornitore di catene raschianti

Scraper Conveyor Chains Manufacturer

La catena di trasporto a raschiatori, componente fondamentale per la trazione continua di materiali sfusi, offre prestazioni eccezionali in quattro ambiti: affidabilità, adattabilità, durata e intelligenza. La combinazione di catene e raschiatori consente il trasporto continuo dei materiali all'interno di un involucro chiuso o semi-chiuso, permettendo di spingerli orizzontalmente, inclinati o verticali. Questa soluzione è ampiamente utilizzata in settori industriali gravosi come miniere sotterranee, cementifici, impianti di lavaggio del carbone e metallurgia. Come elemento chiave nel trasporto dei materiali, le nostre catene di trasporto a raschiatori garantiscono stabilità operativa, elevata resistenza e durata, contribuendo a migliorare l'efficienza produttiva e la stabilità delle apparecchiature.

Panoramica sulle catene di trasporto raschianti

High load capacity and stable transportation

Grazie al collegamento rigido tra le catene e il raschiatore, è possibile ottenere un trasporto stabile e ad alta capacità di vari materiali sfusi, come carbone, scorie, cemento e cereali, ecc. Le catene raschianti sono adatte per applicazioni gravose, a bassa velocità e in funzionamento continuo.

Strong structure, suitable for harsh working conditions

With high-strength alloy steel (such as 20CrMnTi), the hardness can reach HRC45-60 after heat treatment. Its wear and impact resistances adapt to harsh environments of coal mines, power plant slag, and metallurgical high temperatures etc.

Elevata affidabilità e bassi costi di manutenzione.

By precisely customizing chains pitch, selecting appropriate materials, and strict heat treatment technology, ensure high tensile strength of chains, and effectively reduce the broken risk of chains, and there is no significant shaking during operation, reducing the wear of chains, guide rail and sprockets, lower the noise during operation, and reduce the long-term maintenance cost.

Flexible arrangement, multi-directional conveying capability

Non solo supporta il trasporto orizzontale, ma può anche essere progettato per il trasporto inclinato o persino verticale in base a esigenze specifiche (come la catena utilizzata nel trasportatore a raschiatore interrato di tipo MC), adattandosi così a terreni complessi e a vincoli di spazio.

Application Scenarios

Coal Industry

Durante l'estrazione del carbone in sotterraneo, le catene raschianti possono trasportare carbone grezzo e vari materiali misti. Grazie alla collaborazione con macchine minerarie e supporti idraulici, è possibile realizzare una meccanizzazione completa dell'attività estrattiva.

Chemical Industry

Per quanto riguarda i materiali in polvere o granulari nell'industria chimica, come pellet di plastica, polveri di resina, fertilizzanti, pesticidi ecc., le nostre catene raschianti possono essere adattate a nastri trasportatori completamente chiusi, risolvendo efficacemente i problemi di fuoriuscita di polvere, umidità del materiale e contaminazione incrociata.

Building Materials Industry

By using alloy steel with deep-layer heat treatment, our scraper chains have high surface hardness and thick layer of wear-resistance, which can transport high dust and abrasive materials(such as cement, lime, sand and gravel, fly ash, slag, quartz sand, etc.), while keep long service life under high-speed running.

Industria dei cereali e dei mangimi

Our scraper chains are uitable to transport agricultural products (such as corn, soybeans, wheat, soybean meal, grain hulls, bran, starch, etc.), free from material jamming, breakage, residue during transportation, meet food grade hygiene requirements, and significantly improve work efficiency and reducing labor intensity for workers.

Metallurgia e attività minerarie

By choosing heat-resistant alloy steel, our chains can withstand stable tensile strength during high temperature, without softening or deformation. Coordinating with reinforced scraper, it can ensure reliable and smooth transportation of high-temperature or abrasive materials (such as ash, slag, slag, coke powder, metal ores, phosphate ore powder, and chromium ore powder etc).

Ports and Logistics

At bulk cargo terminals and storage transfer stations, our scraper chains can achieve continous and large-capacity loading, unloading, and transportation of coal, grain, fertilizers, and other materials, which significantly reduce the turnaround time of vessels/vehicles in port.

Quality Inspection Equipment

With advanced and comprehensive quality inspection equipments, MATECH ensures that scraper chains have qualified dimensions, chemical composition, mechanical properties, wear resistance, etc. For example, use hardness tester to check the surface and core hardness of chain links and pins; Use spectrometer to quickly and accurately analyze the chemical composition of materials; Simulate operating conditions through chain pre-tension testing machine, to test tension, noise, and stability; Use tensile testing machine to determine the maximum breaking load of the chains, ensuring its safety and reliability in industrial applications.

Frequently Asked Questions

Can you custom make scraper chains according to my design or prototype samples?

Yes. We can newly customize the chains according to your own design. If you don't have technical drawings, we can also reproduce it according to your original samples if you have.

Could you please quote sea freight on CFR delivery term?

Sure. Please let us know which destination port is nearest to you, and we will check economical sea freight with our forwarders, based on estimated packing data. So that you can better evaluate the comprehensive costs.

Qual è il periodo di garanzia per le catene raschianti?

Please note we will produce the chains according to the hardness in the drawings. About the lifetime, it's hard to supply an accurate reply to you, mainly because we don't know the use environment and use frequency. But we will supply QA report to you when delivery. Only qualified parts could be shipped to you for use. Normally customized scraper chains are not suitable for warranty.

Can you supply the Certificate of Origin of chains?

Yes. We can supply the Certificate of Origin of chains when delivery, and the extra certificate cost will be quoted when you require.

For scraper chains, what material of scraper you can do?

Possiamo fornire diversi materiali per i raschiatori, principalmente a seconda dell'ambiente di utilizzo e delle condizioni di lavoro delle catene. I materiali che utilizziamo di solito includono acciaio al carbonio, acciaio antiusura, acciaio inossidabile, gomma, nylon e polietilene, ecc.

Do you have tensile testing machine in house?

Yes. For each shipment, our QA team will check the maximum breaking load of scraper chains through the tensile testing machine, and prepare relevant inspection report, to ensure its safety and reliability during your use.
