High Performance Concrete Reclaimer Manufacturer

SINOU’s  Concrete Reclaimer, also named sand-gravel separator, falls into two core series: Rotary Concrete Reclaimer and Vibratory Concrete Reclaimer. It recycles leftover concrete from mixer trucks, separating reusable stone, sand and wastewater for cyclic batching plant production, cutting raw material costs and reducing pollution discharge.

Basic Introduction & Two Main Product Types

SINOU Concrete Reclaimer, also universally known as sand-gravel separator, is core recycling equipment specially developed for concrete batching plants to treat residual concrete leftover inside mixer trucks. It realizes full separation of reusable coarse aggregate, fine sand and washing wastewater, supporting cyclic reuse of raw materials and water resources while cutting solid waste discharge.

The product line is categorized into two mature structural series: Rotary Concrete Reclaimer and Vibratory Concrete Reclaimer, engineered to match different daily processing loads and site layout demands of mixing stations.

1. Rotary Concrete Reclaimer

Its core assembly consists of a rotary stone separation drum and spiral sand conveying auger. The layout supports both forward and reverse installation modes, adaptable to single or dual mixer truck parking stations, enabling flexible layout adjustment according to the actual foundation space of the batching plant. It adopts steady rotary screening mechanics for continuous medium-volume residual concrete recovery.

2. Vibratory Concrete Reclaimer

This configuration combines linear vibrating screening units with a matched spiral sand auger. Driven by dual vibration motors, it delivers high-intensity linear screening motion to break apart agglomerated residual concrete. Designed for high-throughput scenarios, it processes larger volumes of waste mixer truck concrete with cleaner aggregate separation effect compared to rotary structures.

Both series deploy integrated automatic electrical control systems, realizing unattended continuous operation for the full material separation and recovery workflow.

Working Principle

1. Rotary Concrete Reclaimer Principle

● Waste concrete from mixer trucks flows into the equipment’s feed tank; the rotary stone drum first screens out coarse aggregate (stone >5mm).

● Fine sand is conveyed upward via the spiral auger for recycling; screened wastewater flows into sedimentation tanks for water reuse in mixing production.

● The whole process runs continuously with low water content in recovered sand and stable material separation efficiency.

2. Vibratory Concrete Reclaimer Principle

● Vibration motors generate high-frequency linear vibration, tossing mixed concrete materials onto the polyurethane screen deck for layered screening.

● Oversize stone (>5mm) is discharged separately, fine sand is lifted by auger for reuse; wastewater is fully collected for cyclic utilization.

● Linear vibration delivers higher screening intensity, ideal for sites with large daily volumes of residual mixer truck concrete.

Core Product Features

1. Rotary Concrete Reclaimer

● Low upfront investment cost with outstanding water circulation utilization rate, effectively reducing aggregate and freshwater consumption of concrete mixing stations.

● Optimized rotary screening frame structure greatly mitigates sieve aperture blockage issues, maintaining stable separation performance under long-term heavy-duty running conditions.

● Equipped with integrated automatic control system, operation procedures are simplified; flexible forward/reverse assembly structure adapts to compact or irregular plant foundation layouts.

● Recovered sand features low residual water content, which can be directly applied to concrete batching production without extra dewatering treatment.

2. Vibratory Concrete Reclaimer

● Adopts advanced linear vibration screening principle, achieving cleaner and faster separation of stone and sand compared to rotary type.

● Fitted with wear-resistant polyurethane screen panels that deliver extended service life, anti-clogging property and easy internal bin cleaning.

● Guided chute feeding structure ensures uniform material distribution across the screen surface for stable high-capacity processing. Open frame door design facilitates rapid inspection, disassembly and daily component maintenance.

● Low power consumption design matches high output capacity; automatic discharge structure supports continuous unattended operation for large-volume residual concrete disposal.

Shared Advantages for Both Types

● Complete closed-loop recovery workflow for aggregate and wastewater, complying with environmental protection emission standards.

● Robust welded main body structure with wear-resistant lining and auger blades to extend overall equipment service lifespan.

Product Type Classification

1. Rotary Concrete Reclaimer

It adopts rotary drum screening architecture with moderate overall footprint. Oriented for medium-scale concrete mixing stations with regular daily residual concrete treatment volume. The flexible mounting mode fits standard parking bay layouts, delivering stable continuous separation for medium workload scenarios.

2. Vibratory Concrete Reclaimer

Equipped with linear vibration screening structure for large-capacity processing. Suited for large commercial mixing plants that generate massive volumes of leftover mixer truck concrete every day. It provides higher hourly handling capacity and superior separation cleanliness to satisfy high-yield production recycling demands.

FAQ

Q: What’s the key difference between rotary and vibratory concrete reclaimers?

A: Rotary models rely on rotary drum screening with lower initial cost, suited for medium workloads. Vibratory units use high-intensity linear vibration for cleaner separation and larger hourly throughput for high-volume plants.

Q: What particle sizes of aggregate can be recycled?

A: Recovered stone ≥5mm, recyclable fine sand 0–5mm; separated clean aggregates can be directly reused in concrete batching formulas.

Q: Is full automatic operation available?

A: All SINOU Concrete Reclaimer models are equipped with auto electric control systems, no constant manual monitoring required during running.

Q: Can wastewater from separation be reused directly?

A: Yes. Separated water flows to sedimentation pools, and clarified water circulates for mixer washing and concrete mixing to save tap water resources.
