Product Specifications

Technical details and manufacturing context for Collection Chute/Hopper

Definition

The Collection Chute/Hopper is a component used in waste removal systems as the primary collection point for waste materials. Its funnel-shaped design gathers waste from multiple sources and channels it into the main waste stream for processing or disposal. This component ensures controlled material flow, prevents spillage, and maintains system efficiency by providing a smooth transition from collection to transport. The hopper is typically made of stainless steel, with options for carbon steel as indicated by material grades Q235B/304. It is available in capacities ranging from 0.5 to 2.0 m³, with inlet diameters from 300 to 800 mm and outlet diameters from 150 to 400 mm. Wall thickness varies from 3 to 10 mm, depending on material and abrasiveness. Operating temperature ranges from -20 to 80°C for standard carbon steel, with higher temperatures possible with special alloys. Surface treatment includes epoxy coating with a thickness of 80 to 120 μm for corrosion protection, with food-grade options available. The weight of the component ranges from 50 to 500 kg, depending on size and material. General machining tolerance is ±2 mm per ISO 2768-m, and surface roughness is Ra 3.2 to 6.3 μm for smooth material flow. These values are typical reference ranges and must be verified for the specific model and application. The component is designed to interface with upstream equipment outlets and downstream conveyors or valves, and its dimensions should match those interfaces. For procurement, it is essential to confirm the exact specifications with the manufacturer or supplier, as the listed standards and parameters are for reference only.

Working Principle

Waste materials enter the wide opening of the hopper/chute and are guided by gravity and the angled walls toward the narrower discharge opening. The sloped design ensures continuous flow without clogging, while the controlled geometry prevents material bridging or hang-up. The component may include features like vibration systems, liners, or flow aids to maintain optimal material movement. The design relies on gravity and the angle of repose of the material to ensure smooth flow. The hopper's geometry is critical to prevent blockages and ensure consistent discharge. In some configurations, additional aids such as vibrators or air cannons may be used to facilitate flow, but these are not standard features and must be specified separately.

Frequently Asked Questions

What materials are available for the Collection Chute/Hopper?

The standard material on file is stainless steel, with material grade options including Q235B (carbon steel) and 304 (stainless steel) as per GB/T 700 and GB/T 3280. The choice depends on the application and required corrosion resistance.

What are the typical capacity and dimensions?

Typical hopper volume ranges from 0.5 to 2.0 m³. Inlet diameter is 300–800 mm, outlet diameter is 150–400 mm, and wall thickness is 3–10 mm. These are reference ranges; exact values must be confirmed for the specific model.

What is the operating temperature range?

For standard carbon steel, the operating temperature is -20 to 80°C. Higher temperatures may be possible with special alloys, but this must be verified with the manufacturer.

What surface treatments are available?

The standard surface treatment is epoxy coating with a thickness of 80–120 μm for corrosion protection. Food-grade options may be available, but this should be confirmed with the supplier.
