Appliance Counterweight Precast Concrete Batching Plant Commissioned in Hefei, China

Project Location: Hefei, Anhui, China
Application: Appliance Cement Counterweight Production
Main Mixer: CO-NELE CMP750 Planetary Concrete Mixer
Plant Type: Customized Precast Concrete Batching Plant
Status: Successfully Commissioned in 2026

Precast Concrete Batching Plant for Counterweight Project Overview

In 2026, CO-NELE successfully commissioned a customized precast concrete batching plant for appliance counterweight production in Hefei, Anhui, China.

The project was developed for the production of cement counterweights used in washing machines, refrigerators, air conditioners, and other home appliances.

Appliance counterweights require stable material proportions, high concrete density, consistent weight, and reliable production efficiency. Based on these requirements, CO-NELE designed an integrated batching and mixing solution combining automatic aggregate batching, hopper feeding, and a CMP750 planetary concrete mixer.

Customized Batching Plant for Appliance Counterweights

The complete production line includes:

CMP750 Planetary Concrete Mixer

The CO-NELE CMP750 planetary concrete mixer provides intensive forced mixing through planetary movement of the mixing system.

Its mixing trajectory covers the mixing area effectively, helping achieve a homogeneous and dense concrete mixture. This makes the CMP750 particularly suitable for precast concrete applications where mixing uniformity and product consistency are critical.

The CMP750 has a 750 L output capacity and can handle approximately 1,800 kg of material per batch under the listed specifications.

3-Bin Automatic Batching Machine

The three-bin automatic batching system provides controlled aggregate feeding and accurate proportioning.

For appliance counterweight production, stable batching is essential for maintaining consistent concrete quality and minimizing variation between production batches.

Hopper Lift Feeding System

The hopper lift system provides reliable vertical material transfer from the batching section to the mixer.

Its compact configuration helps optimize the overall plant layout while supporting continuous and efficient production.

Why a Planetary Mixer for Appliance Counterweights?

Cement counterweights are typically manufactured as precast concrete products and require a mixture with good uniformity, density, and dimensional consistency.

The planetary mixing principle combines rotation and revolution of the mixing tools, creating intensive material movement throughout the mixing chamber. CO-NELE's planetary mixers are designed for precast concrete and other demanding mixing applications.

For this Hefei project, the CMP750 was selected to provide:

• High mixing uniformity
• Dense and consistent concrete
• Stable batch-to-batch quality
• Reliable operation for repetitive production
• Efficient integration with an automatic batching system

Production Solution

The production process can be summarized as:

Aggregate Batching → Automatic Weighing → Hopper Feeding → CMP750 Planetary Mixing → Concrete Discharge → Counterweight Molding

By integrating batching, feeding, and mixing into one customized production system, the plant provides a more consistent production workflow for appliance cement counterweights.

Project Results

After commissioning, the customized batching plant provides the customer with a dedicated solution for high-consistency appliance counterweight concrete production.

The system is designed to help manufacturers improve:

Material Consistency | Concrete Density | Product Weight Stability | Production Efficiency | Process Reliability

The project demonstrates CO-NELE's ability to customize precast concrete batching plants and planetary mixing systems according to specific product and production requirements.
