Rake for Rake Carrier

Vishal Engi - Chem manufactures complete rake assemblies and replacement rakes according to customer drawings, existing samples, OEM references and site measurements. Each rake can be customized according to carrier width, chain pitch, chain centre distance, rake spacing, mounting arrangement, operating speed and material-handling capacity.

Depending on the equipment design, rakes can be manufactured from heavy-duty steel pipes, square or rectangular hollow sections, channels, angles, formed plates or built-up box-section beams. Scraper plates, rake blades, gussets, mounting brackets, chain attachments and strengthening ribs are accurately fabricated and welded to form a rigid assembly.

Material options include mild steel, structural steel, high-grade carbon steel, alloy steel and stainless steel such as SS 304, depending on the customer specification and the corrosive or abrasive nature of the application. Replaceable wear plates and additional reinforcement can also be provided for high-wear areas.

Our machining facilities support the accurate production of rake-carrier components and mating parts. Capabilities include:

• CNC and VMC machining

• Precision drilling, boring, milling and slotting

• Turning of pins, bushes, sleeves, shafts, hubs and spacers

• Keyway cutting, attachment-slot cutting and template drilling

• Chain-attachment hole machining and matched-hole manufacturing

• Sprocket and associated conveyor-component machining

Special attention is given to mounting-hole pitch, chain centre-to-centre distance, rake length, bracket position and dimensional consistency. Accurate machining helps the rake assembly fit correctly with the carrier chain and maintain uniform movement across the conveyor width.

Vishal Engi - Chem undertakes light, medium and heavy fabrication jobs for sugar mill machinery and industrial material-handling equipment. Our fabrication capability includes CNC profile cutting, CNC plasma cutting, laser cutting, plate shearing, bending, rolling, forming, drilling, structural fit-up, jig fabrication and trial assembly.

Rakes are fabricated using controlled fixtures and templates to maintain straightness, squareness and parallel alignment. Reinforcement plates, stiffeners and gussets are positioned according to load direction and operating duty. Complete rake assemblies can be supplied in painted, semi-finished or ready-to-install condition.

Our welding capabilities include MIG/MAG welding, TIG welding and conventional arc welding for mild steel, carbon steel, alloy steel and stainless-steel components. Proper edge preparation, root-gap control, weld sequencing and inter-stage inspection are followed according to material thickness and joint design.

We undertake welding of rake blades, scraper flights, pipe or box-section cross-members, mounting brackets, chain-attachment plates, gussets and structural supports. Hard-facing, wear-resistant weld deposits and additional strengthening plates can be provided when required for abrasive bagasse or biomass-handling applications.

Each rake for a rake carrier is precision-manufactured and inspected through a multi-stage quality-control process. Inspection parameters include:

• Overall rake length, cross-section and chain centre-to-centre distance

• Mounting-hole pitch, diameter and attachment alignment

• Straightness, parallelism, squareness and scraper-blade position

• Weld size, continuity, appearance and rake profile

• Trial fitting, surface finish and protective coating

Material test certificates, dimensional reports and additional non-destructive weld testing can be arranged when specified by the customer.
