For small-scale gold ore crushing needs with a daily processing capacity of 60 tons (60 tpd), selecting suitable equipment requires balancing processing capacity, equipment reliability, and economy. Based on industry practice and equipment parameters, the following are some recommended gold ore crushers suitable for this scale.
Jaw Crusher: The First Choice for Coarse Crushing
Jaw crushers are ideal for coarse crushing of gold ore. They have a simple structure, are easy to maintain, and are suitable for processing ores with high hardness. For a scale of 60 tpd, jaw crushers with a processing capacity in the range of 1-400 tons/hour can be considered. For example, PE series jaw crushers (such as PE250×400) have a production capacity of approximately 80-80 tons/hour and are a common choice for small crushing plants. This type of equipment allows a maximum feed particle size of up to 210 mm, which can meet the coarse crushing needs of most small gold mines.
Hammer Crusher: A High-Efficiency Solution for Medium and Fine Crushing
Hammer crushers are suitable for crushing materials with medium hardness and below, featuring a large crushing ratio and uniform product particle size. For a scale of 60 tpd, a small hammer mill with a processing capacity of 800-1500 kg/h is a suitable choice. These machines are typically motor-driven, with a power output of around 11 kW, and the output particle size can be controlled to around 1 mm, making them suitable for fine crushing of gold ore.
Double Roll Crusher: Less Over-crushing
Double roll crushers are commonly used in gravity separation plants due to their low over-crushing rate. For a scale of 60 tpd, a small double roll crusher (such as the Universal Scientific Industrial brand) has a processing capacity of approximately 55.34 m³/d, an output particle size adjustable to 5.33 mm, and a power output of 2.638 kW, making it suitable for applications requiring high-quality finished product particle size.
Equipment Selection Recommendations
When selecting equipment, it is important to ensure the matching of processing capacities between coarse and fine crushing equipment to avoid over-engineering or under-engineering. Simultaneously, the wear resistance of the equipment (e.g., using high-manganese steel or tungsten carbide jaw plates) and energy consumption should be considered. For mining areas with unstable power supply, diesel-powered crushers can be considered.
In summary, a small gold ore crushing system with a processing capacity of 60 tpd can combine a jaw crusher for coarse crushing, and then use a hammer or double roll crusher for medium and fine crushing, forming an efficient and economical crushing production line.
