Looking for a Reliable Small Ball Mill (900x1800) for 1TPH Gold Ore Grinding?

1tph Small Ball Mill Machine 900X1800 for Gold

1 tph Small Ball Mill 900X1800

In the field of mineral processing, especially in small-scale gold mining development or pilot production, choosing an efficient, reliable, and economical ball mill is crucial for success. As a mineral processing equipment manufacturer with 20 years of experience, we deeply understand our customers' needs. Today, we will provide an in-depth analysis of a highly regarded model the 1 ton/hour small ball mill 900X1800 and explore why it is an excellent starting point for gold ore grinding.

In-depth Analysis: Why 900X1800?

The topic 1 ton/hour small ball mill 900X1800 precisely targets a specific market segment: small-scale gold mining projects. The model 900×1800 represents the diameter (900 mm) and length (1800 mm) of the ball mill cylinder, a classic small ball mill specification. Its rated processing capacity of 1 ton/hour is specifically designed for small gold mines, inpidual gold prospectors, or pilot production lines with a daily processing capacity of around 20-30 tons.

For gold ore, grinding is a critical step in separating gold particles from gangue, and its fineness directly affects the recovery rate of subsequent cyanidation leaching or flotation. Therefore, the core value of this equipment lies in: achieving effective grinding of gold ore under limited investment and space conditions, laying a solid foundation for gold extraction.

Equipment Overview: Classic Design, Reliable Core

This 900×1800 ball mill is a horizontal cylindrical rotating device, using either edge drive or center drive. The cylinder is lined with high-manganese steel liners and contains grinding steel balls of different specifications. When the cylinder rotates driven by a motor, the steel balls are lifted to a certain height by centrifugal force and friction, then fall, impacting and grinding the gold ore inside the cylinder, ultimately grinding it into fine powder. • Feed size: Typically ≤25mm

• Discharge particle size: Adjustable within the range of 0.074-0.4mm (suitable for most gold ore leaching requirements)

• Installed power: Approximately 18.5-22kW

• Structural features: Integrated frame, easy installation, stable operation, and minimal maintenance points.

Equipment Core Advantages: Why choose our 900X1800?

With 20 years of manufacturing experience, we have continuously optimized this model, making it stand out in small-scale gold ore grinding:

1. Low investment cost, quick return on investment

For startups or small projects, controlling initial investment is crucial. Compared to large equipment, this model significantly reduces procurement costs, infrastructure costs, and operating energy consumption, helping customers quickly launch projects and shorten the return on investment cycle.

2. Stable operation, easy maintenance

We use high-quality cast steel end caps, precision-machined gears, and heavy-duty rolling bearings to ensure continuous and stable operation. The simplified mechanical structure makes daily maintenance and replacement of wear parts (such as liners) very convenient, reducing the hidden costs of long-term operation.

3. High grinding efficiency, adjustable fineness

Targeting the characteristics of high hardness and the need for fine grinding of gold ore, we have optimized the cylinder length-to-diameter ratio and liner waveform to improve grinding efficiency. By controlling the feed rate and adjusting the grinding media ratio, the discharge fineness can be flexibly controlled to meet the requirements of different processes (all-slime cyanidation or flotation).

4. Small footprint, flexible layout

The equipment is compact, requiring minimal plant and foundation requirements, making it ideal for use in space-constrained mining areas or on mobile beneficiation plants.

Application Case: Successful Gold Ore Grinding

Our successful application at a small hard rock gold mine in West Africa is a prime example of this equipment's capabilities. The client processes 25 tons of raw ore per day, with gold present in fine disseminated form within quartz veins. We configured a 900×1800 ball mill for them, forming a closed-circuit grinding system with a spiral classifier. The final grinding fineness reached 85% passing -200 mesh, and the gold leaching rate increased from less than 40% after direct crushing to 91.5% after grinding, resulting in significantly improved economic benefits.

Recommended Equipment: Building a Complete Grinding System

A ball mill requires supporting equipment to achieve maximum efficiency. We recommend:

• Feeding equipment: Small plate feeder or electromagnetic vibrating feeder to ensure uniform and stable feeding.

• Classification equipment: High-frequency vibrating screen or spiral classifier to achieve timely classification of qualified particle sizes and improve system efficiency.

• Auxiliary equipment: Jaw crusher (PE250×400) for primary crushing to ensure the particle size entering the mill; small stirring leaching tank or flotion machine for subsequent gold extraction.

Frequently Asked Questions (FAQ)

Q1: Is the 1 ton/hour processing capacity of this ball mill fixed?

Not entirely. 1 ton/hour is a reference standard value. The actual processing capacity will be affected by factors such as the hardness of the gold ore, the feed particle size, the required output fineness, and the grinding media filling rate. The output can fluctuate to some extent through process adjustments.

Q2: Does the equipment include grinding steel balls upon delivery?

Generally, the standard factory configuration does not include grinding media (steel balls). However, we will provide a professional steel ball size and ratio plan free of charge based on the properties of your gold ore. You can purchase them locally or entrust us to purchase them on your behalf.

Q3: How long does it take from placing an order to equipment installation and operation?

Since this is our regular model, we usually have stock or a very short production cycle. After receiving the down payment, shipment can generally be completed within 15-20 days. We provide detailed foundation drawings and installation instructions, and customers can complete installation and commissioning within about 1 week after receiving the equipment.
