Jiangxi Mingxin's CRT mechanical cutting machine demonstrates significant technological advantages in the crushing and recycling of waste TVs, first and foremost in its efficient automated processing capability. The equipment adopts a design featuring a rotating table and multiple sets of limit adjustment devices, which can be compatible with CRT picture tubes of different specifications. It achieves precise cutting through a servo motor-driven ball screw transmission system, and when combined with the continuous operation mode of the electric cutting machine, it can process over 220 waste CRT monitors per day (8 hours) — far exceeding the efficiency of traditional manual disassembly. Compared with the high cost of laser cutting equipment and the high wear issue of diamond cutting, this machine achieves a breakthrough in "low-cost large-scale operation" through mechanical structure optimization. Meanwhile, it avoids the drawbacks of the electric heating wire splitting method, such as uneven cutting edges that require secondary processing, greatly reducing the need for manual intervention and saving a large amount of labor costs for recycling enterprises.
In terms of environmental protection and safety performance, the equipment has built a full-process pollution prevention and control system. During the cutting process, it is equipped with a circulating water tank and a synchronous water spray device. Water nozzles are used for real-time dust reduction and capture of cutting debris. Wastewater is introduced into a separate water tank through a chute, and after sedimentation and filtration, it is recycled — minimizing the risk of dust pollution and leaded glass debris diffusion from the source. This physical cutting process completely avoids the wastewater treatment problems caused by solutions such as nitric acid and hydrofluoric acid in chemical disassembly methods, and also prevents the damage to glass components caused by thermal deformation methods. It ensures the safe separation of leaded cone glass and lead-free screen glass, strictly complying with the requirements for heavy metal pollution control specified in the Regulations on the Recycling and Management of Waste Electrical and Electronic Products.
The equipment's role in enhancing the recycling value of resources is particularly prominent. Through precise cutting positioning and stable mechanical operation, it can completely separate leaded glass, ordinary glass, and metal components in CRTs, solving the problem of difficult recycling and reuse caused by mixed materials in traditional methods. Compared with the high investment required for laser cutting equipment, it adopts an economical blade design and a modular structure, which reduces equipment investment and operation and maintenance costs while ensuring neat cutting surfaces. This efficient separation technology increases the recovery rate of tube screen glass to over 90%, and leaded cone glass can be safely sent to professional institutions for treatment. This significantly improves the purity and market value of recycled materials, helping recycling enterprises increase profit margins in an industry environment with tightening policies and promoting the transformation of electronic waste recycling from "environmental compliance" to "economic benefits".
