Client Background
A cement production base under a renowned Pakistani building materials group, driven by business expansion needs, sought to optimize the raw material conveying process in its limestone crushing section. With the dual goals of boosting production capacity and achieving environmental compliance, the company urgently required a professional and reliable heavy-duty feeding equipment solution.
Challenges
- Stringent raw material characteristics:They has high requirements on the wear resistance and impact resistance. Limestone stored in the raw material silo has a particle size exceeding 1000mm and a density of 2400kg/m³.
- Harsh operating conditions:Outdoor operations. High-temperature and high-humidity climates. Strong impact from material unloading, which further accelerates equipment wear.
- Bottlenecks of existing equipment:The original vibrating feeder frequently encountered problems. Such as, material jamming and chain plate deformation. Which is requiring up to 8 maintenance shutdowns per month, which severely restricted production capacity release;
- Clear core needs:To achieve efficient and stable raw material feeding while keep production expansion, efficiency improvement and environmental emission reduction.
Solution
After rigorous multi-party inspections and technical comparisons, they selected Yingda Heavy Industry’s WBZ series heavy-duty apron feeder. The key highlights of the solution are as follows:
- Optimized structural design: Adopts 20mm thickened wear-resistant chain plates and a four-point force-bearing design, capable of directly withstanding the strong impact of ore truck unloading and adapting to the conveying of high-density materials;
- Precise regulation capability: Realizes flexible adjustment of feeding capacity from 0 to 800t/h through precision speed control technology, forming seamless linkage with the subsequent jaw crusher;
- Environmentally adaptive design: Fully enclosed structure effectively suppresses dust diffusion, complying with environmental compliance requirements.
Project Outcomes
After project commissioning, the equipment performance exceeded expectations, with significant improvements in key indicators:
- Greatly enhanced stability:The continuous operation failure rate dropped to below 0.3%. The monthly maintenance time was reduced to within 2 hours;
- Remarkable efficiency improvement:Limestone crushing efficiency increased by 30%, helping the enterprise successfully achieve its production expansion goals;
- Compliance with environmental protection and energy conservation standards:Dust emissions were reduced by 90%. Energy consumption was 15% lower than that of traditional models;
- Substantial cost savings:The client saved over 600,000 yuan in production costs annually. Which achieving a win-win situation of economic and environmental benefits.
Client Feedback
The relevant person in charge of the Pakistani building materials group stated: “Yingda Heavy Industry’s WBZ series heavy-duty apron feeder perfectly adapts to our harsh operating conditions and production expansion needs. The stability, efficiency and environmental performance of the equipment exceed expectations. This cooperation not only solved our production bottlenecks but also demonstrated Yingda Heavy Industry’s strong technical strength in the field of heavy-duty conveying equipment. We look forward to more in-depth cooperation in the future.”
