The shredder+crusher can recycling production line enables the purity of recycled aluminum to reach 99%+and reduces costs by 45%

1、 Customer background

Customer Name: Recycle Co., Ltd

Industry field: Recycling of waste cans (aluminum, steel), processing of recycled metals, core supply to downstream aluminum profile factories and can making factories

Collaboration time: April 2024

Core requirement: After recycling, the cans contain a lot of impurities (label paper, residual beverages, plastic caps) and have a loose volume, resulting in high transportation costs. The original manual sorting+simple crushing mode has low efficiency and insufficient purity. A set of "capacity reduction crushing impurity removal" integrated production line is needed to achieve efficient resource recycling of cans.

2、 Customer core pain points

High impurity rate and low selling price: The label paper on the surface of the can, the built-in plastic cover, and the metal adhesion make manual sorting incomplete. The original crushed material has a impurity rate of 12%, and the purity of recycled aluminum is only 88%. Downstream manufacturers are cutting prices by 18%, and the profit margin is narrow.

High transportation costs: Untreated cans have a void ratio of 85%, and each vehicle can only load 2-3 tons. The unit cost of transporting from the recycling point to the processing plant is 65 baht/kg, accounting for 30% of the total cost.

Low efficiency and manual dependence: manual sorting and simple crushers require 6 workers to work in shifts, with a single ton processing time of 1.5 hours and a daily production capacity of only 12 tons, which cannot digest the daily recycling volume of 20 tons, resulting in a large amount of raw material accumulation.

Environmental risk: Leakage of residual beverages and dust generated by broken label paper, which does not comply with the local Industrial Waste Management Law, and faces a warning for rectification.

3、 Solution: Gangzheng can recycling production line

In response to the characteristics of "lightweight, diverse impurities, and the need for efficient capacity reduction and impurity removal" of cans, we have customized a "dual axis shredder+efficient crusher" linkage production line, equipped with intelligent impurity removal and environmental protection systems:

1. Core equipment configuration

GZ-1400 Double Axis Shredder: Equipped with 75kW dual motors and high-strength alloy steel disc, the feeding port can directly process the entire package of cans (without unpacking), and achieve capacity reduction through shear crushing. The discharge particle size is 20-30cm, the porosity is reduced to 40%, and the label paper is preliminarily peeled off.

GZ-250 high-efficiency crusher: equipped with a 250kW motor and wear-resistant alloy hammer head, the crushing chamber is optimized for the shredded cans. Through high-speed impact, "fine crushing+impurity separation" is achieved, with a discharge particle size of 3-5cm. The built-in strong magnetic separation device separates steel cans fragments, and the air separation system removes lightweight label paper and plastic caps.

2. Upgrade the supporting system

Automatic feeding+conveying linkage: The belt conveyor connects the shredder and the crusher, achieving seamless connection of "capacity reduction crushing impurity removal" without the need for manual transportation;

Environmental protection treatment module: closed dust collection device+liquid recovery tank, dust emission concentration ≤ 8mg/m ³, centralized recycling and treatment of residual beverages, no leakage pollution;

Simple control system: one click start stop+overload protection, low operating threshold, supports automatic fault alarm.

3. Service guarantee

Cross border installation team: A team of 3 engineers will travel to Thailand and complete the construction, debugging, and environmental inspection of the production line within 7 days;

Multi language support: Provide Thai and English operation manuals, on-site practical training, covering equipment operation and maintenance points;

After sales support: 1-year full machine warranty+6-month warranty for core vulnerable parts (cutterhead, hammer head), Southeast Asian spare parts warehouse, response time ≤ 48 hours.

4、 Implementation effect (data-driven presentation)

Double increase in purity and selling price: The purity of recycled aluminum/steel has been increased from 88% to over 99%, the impurity rate has been reduced to less than 1%, and the downstream purchase price has been increased by 15%. We have successfully connected with Thailand's TOP3 aluminum profile factories and obtained long-term supply orders.
Significant reduction in overall costs:

Labor cost: Only one operator and one inspector are needed per shift, saving 83% of labor costs and reducing expenses by approximately 120000 Thai baht per month;

Transportation cost: After crushing and reducing capacity, the loading capacity of each vehicle increases to 8-10 tons, and the unit transportation cost is reduced to 30 Thai baht/kg, saving about 80000 Thai baht in transportation costs per month;

Environmental cost: Eliminating rectification risks without the need for additional sewage treatment equipment, saving about 30000 Thai baht in monthly environmental related expenses.

Significant increase in revenue: Monthly net profit increased by approximately 280000 Thai baht, with an investment return period of only 9 months, making it a benchmark enterprise for efficient recycling of cans in the Bangkok area.

5、 Customer feedback

Mr. Su, General Manager of Recycle Co., Ltd.: "Gangzheng's production line has completely changed our recycling model! Previously, handling cans was labor-intensive and dirty, and the purity was not up to standard. Now, with full automation from feeding to producing clean metal fragments, 99% purity has allowed us to sell at a higher price. Half of the transportation costs have been saved, and environmental issues have been completely resolved. The equipment has been running without any malfunctions for 6 months, and the technical support from the after-sales team is very timely. We have planned to purchase another production line to cover the cans recycling business in two surrounding provinces
