1. فتحة مدفوعة بنقطة الألم

Are you facing persistent bottlenecks in your gold processing circuit due to unreliable or inefficient comminution? The challenges of pilotscale testing and process validation for gold recovery are welldocumented. Inconsistent or inaccurate results from your export stamp mill gold mining testing can lead to costly downstream errors, مشتمل:
سوء تخصيص رأس المال: Scaling up a process based on flawed liberation data risks millions in underperforming plant equipment.
Recovery Uncertainty: Without precise grind size control and reliable discharge simulation, predicting actual gold recovery and grade is guesswork.
التوقف التشغيلي: Testing delays or equipment failure directly postpone project timelines and revenue generation.
تكاليف تشغيل عالية: غير فعال, manuallyintensive test milling consumes excessive labor, قوة, and sample material.

How can you obtain definitive, scalable data to derisk your gold project investment? The answer lies in moving beyond antiquated methods to engineered, precision testing equipment designed for the specific demands of gold ore characterization.

2. نظرة عامة على المنتج

This product line comprises engineered, وحدات export stamp mill gold mining testing وحدات. These are not replicas of historical production stamps but are precisiondesigned batch mills that simulate the mechanical crushing and grinding action of a traditional stamp battery for the explicit purpose of metallurgical testing and process flowsheet development.

سير العمل التشغيلي:
1. تحضير العينة: A calibrated mass of crushed ore feed (عادة 6 ملم) is loaded into the mortar box.
2. الطحن الدقيق: Programmable camshafts lift and drop weighted stamps onto the ore bed with controlled frequency and force, achieving targeted particle size reduction.
3. التفريغ الخاضع للرقابة & مجموعة: The ground pulp is discharged through an interchangeable screen grate, simulating a closedside setting, and collected for washing and concentration.
4. تحليل: The resulting product is analyzed for grind size (ص80), mineral liberation, and subjected to gravity concentration or cyanidation tests to establish recovery parameters.

نطاق التطبيق & القيود:
نِطَاق: مثالية لطحن خامات الذهب مجانا, sulphideassociated gold ores requiring gravityrecoverable gold (GRG) testwork, pilot plant feed preparation, and calibration of comminution models. Essential for feasibility studies where traditional stamp mill performance data is required.
القيود: Not designed for continuous production or hightonnage processing. Less effective for purely refractory ores requiring ultrafine grinding without supplementary equipment.
