Sand and Gravel Separator Chute Made in China

SINOU is a reliable manufacturer of Sand and Gravel Separator Chute, this type of equipment is also known as flat-ground feeding lift chute, is an indispensable front-end feeding auxiliary device for both Rotary Concrete Reclaimer and Vibratory Concrete Reclaimer.

Different from traditional slope-style feeding trenches that require civil ramp construction, this machine adopts spiral blade and bucket wheel lifting mechanism to realize mixer truck unloading on flat ground directly.

It drastically cuts foundation construction investment, shortens project construction cycles, and boosts the whole feeding efficiency of sand-gravel separation systems for concrete batching plants.

Unique Working Mechanism

1. Flat-ground feeding: Mixer trucks park on level ground to discharge leftover concrete and flushing sewage into the wide receiving tank of the lift chute, no ramp foundation needed.

2. Mechanical spiral lifting: Internal spiral blade assembly lifts mixed aggregate and wastewater steadily to the designated feeding height matched with sand-gravel separators.

3. Homogenized material delivery: Bucket wheel auxiliary structure disperses agglomerated concrete lumps evenly, avoiding localized material piling and uneven feeding to the reclaimer main unit.

4. Synchronized sewage diversion: Integrated water guide channels separate wastewater from aggregates during lifting, guiding sewage to sedimentation facilities for cyclic reuse simultaneously.

5. Auto-cycle operation: Linked with the automatic control cabinet of concrete reclaimers, the lift chute starts and stops synchronously with separation equipment to achieve unattended feeding flow.

Complete Structural & Component Breakdown

1. Heavy-Duty Welded Main Tank Body

The outer shell is built with extra-thick carbon steel through full penetration welding, processed by stress relief to resist long-term impact and deformation from concrete materials. Outer surface undergoes anti-rust primer and topcoat painting, adapting to muddy, high-humidity outdoor mixing station environments. Wide open feed inlet maximizes unloading tolerance for mixer trucks.

2. Spiral Lifting Core Assembly

High-torque spiral shaft paired with thickened wear-resistant spiral blades forms the lifting core. Blades adopt surfacing wear-resistant treatment to withstand continuous friction of sand, stone and cement mortar. Sealed waterproof bearing seats at both shaft ends stop mortar and sewage from corroding transmission parts.

3. Bucket Wheel Auxiliary Disturbance Unit

Matched bucket wheel structure rotates synchronously with the spiral system, breaking up hardened concrete chunks before lifting. It prevents large agglomerates from blocking spiral gaps and ensures uniform material conveying volume to downstream separation equipment.

4. Drive & Automatic Control System

Equipped with 7.5kw stable drive motor, matched with reduction gearbox for steady low-speed high-torque output. Supporting full-auto electric control cabinet realizes interlock start-stop with rotary/vibratory concrete reclaimers; overload, stall and leakage protection functions are embedded to safeguard the whole feeding system.

5. Wear-Resistant & Splash-Proof Accessories

Inner tank wall lined with high-hardness wear-resistant steel plates to extend service life; surrounding heightening anti-splash baffles stop material splashing during truck unloading. Modular design for quick disassembly and replacement of worn liners and blades.

Differentiated Competitive Strengths

1. Zero ramp civil engineering cost:

Enables flat-ground mixer truck parking, eliminating expensive slope foundation excavation and concrete pouring work for mixing stations.

2. Higher feeding efficiency:

Mechanical forced lifting delivers stable 30m³/h conveying capacity, far more consistent than gravity slope feeding prone to material stagnation.

3. Universal matching compatibility:

Perfectly docks with all specifications of SINOU Rotary Concrete Reclaimer and Vibratory Concrete Reclaimer, adaptable to medium and large-scale batching plant layouts.

4. Compact footprint:

Overall dimension 605030002400mm occupies limited ground space, ideal for mixing stations with narrow reserved equipment zones.

5. Low long-term maintenance:

Thickened wear components have long service cycles; open tank design makes residue cleaning and part replacement fast and labor-saving.

6. Stable full-auto linkage:

Sync control with sand-gravel separators cuts manual monitoring labor and avoids empty-load or overload running of separation hosts.

Application Scenarios & Matching Collocation

1. Ideal Application Sites

● Medium & large commercial ready-mix concrete batching plants without pre-built unloading ramps

● Newly built mixing stations aiming to reduce early civil construction budget

● Renovated old mixing plants where ground reconstruction for slopes is unfeasible

● Temporary municipal, bridge and road construction mixing yards requiring fast equipment deployment

2. System Matching Scheme

(1) Standalone collocation: Pair one mechanical lift chute with a single set of rotary or vibratory concrete reclaimer for independent station production lines.

(2) Multi-unit linkage: Deploy multiple lift chutes feeding one large-capacity vibratory concrete reclaimer for super-large centralized mixing bases.

(3) Auxiliary facility matching: Coordinate with sedimentation tanks, HDPE drainage pipelines and aggregate stockpiles to form a closed-loop leftover concrete recycling workflow.

Standard Routine Maintenance Protocol

1. Lubrication & transmission inspection: Fill qualified lubricant into all bearing seats and gear transmission parts regularly; check whether spiral and bucket wheel rotation runs flexible and jitter-free.

2. Fastener tightness check: Inspect all frame, motor and liner fixing bolts weekly, tighten any loose fasteners to prevent structural shaking during operation.

3. Timely residue cleaning: Clear bonded concrete, mortar and aggregate on spiral blades, bucket wheels and tank inner walls after every work shift to avoid solidification blockage.

4. Site drainage upkeep: Manually clear sludge and sediment in surrounding drainage ditches every day to guarantee unobstructed sewage outflow away from the chute base.

5. Quarterly wear inspection: Measure abrasion loss of spiral blades and wear liners; replace severely worn parts in advance to prevent damage to the main tank body.
