Wet Ball Mill
Introduction
In small and medium-sized mineral processing plants and multi-mineral processing projects, selecting a grinding equipment with matching processing capacity, stable performance, and wide applicability is crucial. As a manufacturer of mobile crushing equipment for mines, we understand the synergistic benefits of the system collaboration between primary crushing and subsequent grinding. This article will focus on a highly efficient piece of equipment widely used in wet grinding applications for gold, copper, lead-zinc, and graphite mines – the 200 tpd capacity, 1830×3600 model wet ball mill – and explain why it is an ideal core component for small and medium-sized mineral processing plants.
Equipment Overview: 1830×3600 Wet Ball Mill
The 1830×3600 wet ball mill is a medium-sized wet grinding equipment with a mature structural design and reliable performance. The model name "1830×3600" typically refers to a cylinder diameter of approximately 1.83 meters (1830 mm) and a length of approximately 3.6 meters (3600 mm). This size of ball mill is designed to have a processing capacity of approximately 200 tons per day (tpd), with the specific output adjustable within a certain range depending on the ore hardness, feed size, and product fineness. It is particularly suitable for processing various non-ferrous and ferrous metal ores as well as non-metallic minerals, and is a core piece of equipment for achieving mineral liberation and providing qualified materials for flotation or leaching operations.

Core Advantages: Why is it a Universal Choice?
The reason this 1830×3600 wet ball mill is the choice for many types of minerals stems from its comprehensive advantages:
Excellent Adaptability and Versatility
This model is a typical "all-rounder." By adjusting its internal liner material, grinding media (steel ball) material and grading, rotation speed, and grinding concentration, it can effectively handle minerals of different hardness and properties. Whether it's relatively soft graphite, easily muddy lead-zinc oxide ore, or medium-hard copper sulfide ore and gold ore, it can achieve efficient grinding through parameter optimization, demonstrating strong adaptability.
Balancing Investment and Operation
For projects with a daily processing capacity of around 200 tpd, the 1830×3600 wet ball mill achieves a good balance between equipment investment, footprint, power consumption, and operating and maintenance costs. Compared to smaller equipment, it generally offers better energy efficiency per ton; compared to larger equipment, it has lower initial investment, simpler installation and foundation construction, making it ideal for small and medium-sized mines, pilot plants, or independent production lines in large mines.
Mature and Reliable, Easy Maintenance
This size is a classic model among wet ball mills, with mature technology and a complete supply chain. Spare parts (such as liners, grinding balls, gears, etc.) are readily available. The structural design facilitates daily inspection, maintenance, and replacement of wear parts, maximizing equipment uptime and reducing long-term operating risks.
Application Case Studies: Successful Practices in Multiple Mineral Types
Gold Mine Project: Processing gold-bearing quartz vein ore, the raw ore is crushed in two stages by jaw crusher and cone crusher to -15mm, then fed into a 1830×3600 wet ball mill, forming a closed-circuit grinding system with a hydrocyclone. The grinding fineness reaches 85% at -200 mesh, providing ideal mineral liberation for the subsequent cyanide leaching process, resulting in a gold leaching rate of over 92%.
Graphite Mine Project: Processing flake graphite, the goal is to protect large flakes and improve purity. A 1830×3600 wet ball mill is used for multi-stage regrinding. By controlling a lower grinding concentration and optimizing the grinding media system, the integrity of the graphite flakes is protected to the greatest extent while effectively stripping the gangue, providing a key guarantee for the production of large-flake high-carbon graphite.
Multi-metal Mine (Copper-Lead-Zinc) Project: The ore properties are complex. A 1830×3600 wet ball mill is used for unified coarse grinding, grinding the ore to a particle size suitable for copper-lead-zinc mixed flotation. Its stable operation and easy adjustability create stable feed conditions for subsequent selective flotation separation operations.
Systematic Collaborative Recommendation: Perfect Integration with Mobile Crushing
To achieve the optimal system configuration for a 200 tpd processing capacity, we recommend the highly efficient combination of a "mobile crushing plant + 1830×3600 wet ball mill":
Front-end Crushing: Configure a mobile crushing and screening system consisting of a "mobile jaw crusher + mobile cone crusher/mobile impact crusher". This system can be flexibly deployed near the mining site, crushing the raw ore to a particle size of -20mm or finer, providing a uniform and stable feed for the subsequent 1830×3600 wet ball mill. This "mobile crushing, semi-fixed grinding" model significantly reduces raw ore transportation costs and enhances the flexibility of the entire production line.
Core Grinding: The 1830×3600 wet ball mill, as the core of the grinding process, receives qualified products from the mobile crushing system for efficient wet grinding.
Back-end Connection: The ground product can be flexibly connected to subsequent beneficiation equipment such as hydrocyclone classifiers, flotation machine units, and leaching tanks, forming a complete, compact, and efficient 200 tpd beneficiation plant.

Frequently Asked Questions (FAQ)
Q1: Is the 200 tpd processing capacity fixed? What are the key factors affecting its actual capacity?
A1: 200 tpd is a design reference value; the actual capacity will fluctuate. Key influencing factors include: ① Ore hardness and grindability: Harder ores will result in lower processing capacity. ② Feed particle size: The finer the feed, the higher the capacity. This highlights the importance of the front-end mobile crushing system providing uniform fine material. ③ Product fineness requirements: The finer the grinding, the lower the capacity. ④ Mill operating parameters: such as steel ball filling rate, grinding concentration, and circulating load. The actual capacity needs to be determined based on specific ore tests.
Q2: What are the differences in operation of this ball mill for gold ore leaching and copper-lead-zinc flotation?
A2: The operational focus differs depending on the application. For gold ore cyanidation leaching, a fine grinding particle size is usually required (to fully expose the gold minerals), and the pH and redox environment during the grinding process must be strictly controlled. Sometimes, reagents such as lime need to be added to the mill. For copper, lead, and zinc flotation, the grinding fineness needs to be determined according to the embedded particle size of different minerals, following the principle of "monomer dissociation without over-grinding," while also paying attention to the influence of pulp potential on flotation. However, the main equipment is generally the same; adjustments are mainly achieved through the media system, concentration, and added reagents.
Q3: Can this equipment be used for dry grinding?
A3: Generally, no. The 1830×3600 wet ball mill is specifically designed for wet processes. Its structure (such as the grate plate or overflow design at the discharge end, and the type of feeder) and internal liner type are designed to adapt to the flow characteristics of the slurry. If used for dry grinding, problems such as dust sealing, poor discharge, and severe material adhesion will occur, resulting in low efficiency. If dry grinding is required, a specially designed dry ball mill should be used.
