SINOU Rotary Concrete Reclaimer is a top-selling rotary drum type sand-gravel separator widely purchased for concrete waste recycling projects. Paired with Vibratory Concrete Reclaimer, this equipment forms a complete concrete recovery solution to handle residual materials from mixer trucks for concrete batching plants.

It adopts mature rotary screening technology, featuring stable operation, flexible installation and cost-effective performance, which is a mainstream choice for medium-scale concrete production facilities worldwide.

1. What is Rotary Concrete Reclaimer?

Rotary Concrete Reclaimer, also known as rotary drum sand-gravel separator, is professional environmental protection equipment dedicated to recycling residual concrete from mixer trucks at concrete batching plants.

Different from Vibratory Concrete Reclaimer that applies vibration screening principles, it takes rotary screening drum and spiral conveying auger as the core working components.

It can automatically separate reusable coarse aggregate, fine sand and cleaning wastewater from waste concrete, building a fully closed-loop resource recycling system.

The compact overall structure supports forward and reverse installation, which adapts to various foundation layouts and limited installation space of on-site mixing stations, effectively reducing raw material waste and meeting international environmental protection discharge standards.

2. Working Principle

How does a standard Rotary Concrete Reclaimer work on site? This equipment operates based on mechanical rotary screening and spiral material conveying.

After residual concrete from mixer trucks flows into the feeding tank, the rotating drum firstly performs primary screening to intercept large-particle coarse aggregate.

The qualified fine sand is continuously lifted and slightly dewatered by the built-in spiral auger, and then delivered to the material storage area for direct reuse. Meanwhile, the separated wastewater is guided to supporting sedimentation tanks for cyclic use in concrete mixing and mixer truck cleaning.

The whole workflow runs continuously and autonomously without frequent manual intervention. When matched with supporting water pipelines and conveying equipment, the rotary concrete reclaimer can work with other auxiliary facilities to build a complete waste concrete treatment production line.

Product Details

1. Main Frame & Overall Structure

The main frame of the rotary concrete reclaimer is fabricated with thickened carbon steel via full welding process. The integral box-type structure features high structural rigidity, strong anti-vibration capability and excellent load-bearing performance, which will not deform or shake during continuous high-load operation. All welding seams are polished and anti-rust treated to adapt to humid and muddy working environments on construction sites.

The whole machine is designed with a compact layout and takes up moderate floor space. It supports forward and reverse two installation modes, so users can flexibly adjust the placement direction of the equipment according to the layout of mixer truck parking areas and plant foundation conditions. Standard safety protective guards are equipped around rotating parts to fully comply with EU mechanical safety standards and avoid operational risks.

2. Rotary Screening Drum Assembly

As the core screening component, the rotary drum adopts reinforced roller design and high-strength wear-resistant screen mesh. The screen holes are scientifically sized to efficiently separate coarse aggregate above 5mm from mixed concrete. The rotating operation mode can automatically shake off adhered concrete residues, effectively solving the common screen blockage problem of traditional separating equipment.

The two ends of the drum are equipped with sealed bearing seats with good dustproof and waterproof effects, which can prevent mortar and sewage from entering and causing component damage. The drum drive unit uses a low-speed high-torque gear motor, enabling the rotary concrete reclaimer to maintain steady rotating speed and stable screening efficiency even when dealing with large lumps of residual concrete.

3. Spiral Conveying & Dewatering Auger

The matched spiral auger is responsible for lifting and dewatering fine sand, which is another key part. The auger shaft is made of solid thickened steel, and the spiral blades are welded with high-hardness wear-resistant steel plates. This design greatly enhances the abrasion resistance of the auger and avoids blade wear, deformation or fracture caused by long-term friction with sand and gravel.

While conveying fine sand upward, the spiral structure can realize natural dewatering. The recycled fine sand processed by the rotary concrete reclaimer has low moisture content and can be directly put into concrete batching without secondary dewatering treatment. The auger drive system runs synchronously with the rotary drum to ensure coordinated operation of the whole equipment.

4. Feeding & Water Circulation Structure

The feeding tank has a large caliber and anti-spattering design, which can smoothly receive residual concrete discharged from mixer trucks and prevent material splashing during feeding. The inner wall of the feeding tank is pasted with wear-resistant lining plates to reduce the impact and abrasion of concrete on the tank body.

The equipment reserves standard interfaces for water pipelines. It can be seamlessly connected with on-site sedimentation tanks and HDPE drainage pipes to collect separated wastewater completely. The recycled water can flow back to the production link for reuse, realizing water resource recycling and zero discharge of sewage. The internal flow channel is optimized to keep the drainage unobstructed and prevent sludge deposition.

5. Electrical Control System

The product is equipped with a fully automatic integrated electric control cabinet, which adopts well-known brand electrical components that meet international electrical standards. The control panel is simple and intuitive, supporting one-click start and stop, automatic operation and emergency stop functions. Operators can master the operation methods quickly without professional training.

The system has built-in overload protection, leakage protection and fault alarm functions. When the equipment is blocked, overloaded or abnormally operated, it will automatically cut off the power and send an alarm signal to protect the motor and core components from damage. The fully automatic operation mode realizes unattended work, effectively reducing manual labor input.

6. Wear-resistant & Auxiliary Components

In view of the harsh working conditions of concrete recycling, all vulnerable parts are made of high-quality wear-resistant materials. In addition to screen mesh and spiral blades, the connecting brackets, support legs and guide chutes are all reinforced and anti-wear treated.
