Clay raw materials
In the mining equipment industry, we often hear complaints from customers about general-purpose equipment. When processing materials change from hard, brittle quartz to soft, cohesive clay and silica sand, standard equipment often reveals numerous problems: screen clogging, crushing chamber adhesion, incomplete washing, and abnormally accelerated wear. This not only leads to a sharp decline in production efficiency but also results in high maintenance costs and significant downtime.
As a deep participant in the industry, we understand that there is no one-size-fits-all equipment, only precise solutions. Today, we will delve into the key technological breakthroughs achieved by crushing, screening, and washing machines specifically designed for materials such as clay and silica sand.
I. Three Major Challenges of Clay and Silica Sand to Traditional Equipment
1. Adhesion and Clogging: Clay exhibits strong plasticity in high-humidity environments, easily forming a stubborn adhesion layer on the jaw plates and impact plates of the crusher. This not only reduces the effective volume but also alters the flow field in the crushing chamber, leading to a sharp drop in efficiency.
2. Differences in Abrasion Characteristics: Quartz stone abrasion is primarily impact and cutting, while the quartz sand particles in clay create a unique micro-abrasive effect on metal surfaces. Simultaneously, the corrosive components of the clay itself accelerate equipment rusting. This combined effect of abrasion and corrosion is fatal to ordinary materials.
3. Washing Efficiency Challenges: Simple rinsing cannot effectively remove the bond between clay and silica sand. Insufficient water flow results in incomplete cleaning, leading to a high mud content in the finished product and affecting quality; excessive water flow causes significant loss of fine sand, reducing recovery rates and causing environmental pollution.
II. How Our Customized Integrated Solution Precisely Addresses These Challenges
Faced with these challenges, our engineers abandoned the approach of standard design with minor adjustments and instead undertook a comprehensive redesign starting from the underlying logic.
Ball Mill for Caly
1. Crushing Module: From Hard-on-Hard to Soft-on-Soft
• Core Innovation: Clog-free design + self-cleaning function. We use a special roller or spiral crushing structure to replace the traditional jaw or cone crusher. Its working mechanism is not compression crushing, but rather decomposition of clay lumps through shearing and grinding. Simultaneously, the equipment is designed with adjustable scrapers or chains to clean the inner wall of any adhering material in real time, ensuring continuous unobstructed flow in the crushing chamber.
• Material Upgrade: Key components are made of high-chromium cast iron or composite ceramic materials, whose extremely high wear resistance and corrosion resistance are specifically designed to meet the abrasive challenges of clay materials, extending the life of vulnerable parts several times over.

2. Screening Module: From Static Waiting to Dynamic Vibration
• Core Innovation: High-frequency dewatering screen and tension screen technology. Addressing the core pain point of screen clogging, we apply a high-frequency dewatering screen. Through high-frequency, low-amplitude vibration, it powerfully dewaters the material while simultaneously causing the material to vigorously agitate on the screen surface, effectively preventing the adhesion of fine clay particles. For extremely fine materials, the polyurethane screen plates of the tension screen undergo tension and relaxation motion, causing the screen openings to constantly change, creating a breathing effect and fundamentally preventing clogging.
• Optimized Configuration: Utilizing a multi-layer screen design and a modular structure for easy and quick replacement, it can be flexibly adjusted according to raw material conditions and finished product particle size requirements, achieving multi-purpose functionality.
Spiral Sand Washer
3. Washing and Screening Module: From Flooding to Precision Guidance
• Core Innovation: Spiral Sand Washer Combined with Hydrocyclone. The core of our washing and screening system is the high-efficiency spiral sand washer. During the sand lifting process, the spiral blades, through continuous mutual friction and agitation, thoroughly break down and separate clay clumps. Wastewater then enters the hydrocyclone assembly, where centrifugal force recovers useful fine sand, significantly improving the yield rate while simultaneously achieving water recycling, meeting environmental protection requirements.
• Water Conservation and Environmental Protection: Equipped with a fine sand recovery device and a sludge sedimentation tank system, forming a closed-loop circulation, minimizing water consumption and sludge discharge, and supporting customers' green production.
