Tailings Crushing Solutions

In brick production, raw material crushing is the primary factor determining brick quality and production costs. The crushing effect of materials such as coal gangue, shale, clay, and slag directly affects the compactness of the green brick and the strength of the finished product. However, when processing these materials, traditional crushing equipment commonly faces three major challenges: easy clogging, rapid wear, and uneven particle size, which seriously affect brick quality and production efficiency.

With over 20 years of experience in the R&D and manufacturing of roll crushers, Huashengming Heavy Industry has launched the double roll crusher specifically tailored for brick plant raw material processing. It has been successfully applied in hundreds of brick plants worldwide, helping customers achieve significant production capacity improvements.

I. Solution Overview

The double roll crusher is widely used in brick plants, mainly for crushing coal gangue, shale, clay, and other brick-making materials. Its working principle involves two counter-rotating rolls squeezing and shearing the material to achieve medium and fine crushing. The equipment features a simple structure, stable operation, low energy consumption, and easy maintenance. The discharge particle size is uniform, effectively meeting the particle size requirements for green brick forming.

Huashengming double roll crushers feature an adjustable double-roll gap design, with precise and controllable discharge size (typically 1–5mm) to meet the particle size requirements of different brick types. The equipment has a compact structure with a small footprint, making it suitable for upgrading small and medium-sized brick plants. Its low-speed operation significantly reduces dust generation, improving the workshop environment.

Core advantages include:

1. No need for frequent wear parts replacement — average roll shell service life of over 2 years

2. Well-shaped sand particles — reasonable gradation, low over-crushing rate, high output

3. Discharge size adjustable from 1–3mm — meeting different brick type requirements

4. Capable of crushing both dry and wet materials — no clogging, no sticking

5. High-chromium manganese steel wear-resistant roll shells — alloyed with rare metals, patented technology

6. Stable operation with low noise and low dust — meeting environmental production standards

II. Practical Application Case

In the South African market, brick-making raw material prices are relatively high. A local brick plant had long faced operational pressure from high raw material costs. After extensive evaluation, the customer chose Huashengming’s 800×600 hydraulic double roll crusher.

The equipment is powered by dual 30kW motors with Jiangsu Guomao reducers, providing ample power and stable operation. Through its double-roll squeezing crushing technology, the equipment processes materials such as mine waste rock and tailings—which would otherwise be difficult to utilize—into fine aggregates that meet brick production requirements, effectively expanding the brick plant’s raw material sources and reducing dependence on high-cost materials.

After commissioning, through precise crushing and optimized resource utilization, the equipment not only improved the overall operational efficiency of the brick production line but also gave the customer a cost advantage in the fiercely competitive market. This case confirms the reliable product performance and highly customized service capabilities of Huashengming crushers on a global scale.
