Project Description:
To address the pain points of traditional sand and gravel plants, such as long construction cycles and heavy environmental burdens, this 2,500-ton-per-hour sand and gravel production line adopts a prefabricated modular construction model—all steel structures are prefabricated in the company's workshop and then assembled on-site, reducing on-site construction time by 60%. The production line is equipped with an intelligent central control system that monitors the real-time operating status of core equipment such as the hammer crusher and dual-rotor sand making machine. In terms of environmental protection, a combination of fully enclosed operation and pulse dust collectors achieves near-zero dust leakage, with a fine sand recovery rate exceeding 95%.

The core of the production line is a five-stage closed-loop process: crushing, shaping, screening, sand making, and washing. A heavy hammer crusher efficiently processes raw materials, while a hammer mill optimizes particle angles. A dual-rotor sand making machine deeply shapes the particles, and a powder classifier precisely controls the stone powder content. An innovative "spiral + wheel" dual-stage sand washing system, combined with an integrated fine sand recovery machine, results in a finished sand with low mud content. The entire production line utilizes recycled water resources, and a baghouse dust collection system ensures clean production and efficient resource utilization.

Project Features：
The 2,500-ton-per-hour sand and gravel production line of Tianli Building Materials in Xinxiang City, Henan Province, was designed and constructed by Zhongyu Dingli. It adopts the processing method of heavy hammer crusher and shaping crusher, with strong crushing capacity, one-stage crushing and snail shell design, which enhances the impact resistance of the inside and outside, and ensures that the machine shell is strong and does not deform. Through movable liner, it realizes impact crushing and impact shaping, reducing the proportion of needle and flaky material and stone powder rate of finished material.
