As a common equipment in the field of mining crushing, PEX350×750 jaw crusher is widely used in small and medium-sized production lines with its stable performance and efficient crushing capacity. Its feeding requirements and discharging effects directly affect production efficiency and finished product quality, and need to be comprehensively considered in combination with equipment parameters and material characteristics.
1. Feeding requirements of PEX350×750 jaw crusher
Particle size limit
The maximum feed particle size of this model is 300mm. If the material exceeds this size, it will cause blockage or equipment overload. In actual production, it is recommended to control the feed within 250mm to ensure effective bite of the crushing chamber.
Material characteristics
Hardness: Suitable for ores with compressive strength ≤320MPa. Excessive hardness will accelerate the wear of the jaw plate and reduce production capacity.
Humidity: Excessive humidity can easily cause sticky cavity. It is recommended that the water content should not exceed 10%.
Ingredients: Non-crushable objects such as iron parts need to be screened out in advance to avoid damage to the hydraulic overload protection system.
Uniform feeding
A vibrating feeder is required to avoid direct dumping that may cause overloading or blockage of the crushing chamber.
2. Discharging effect of PEX350×750 jaw crusher
Particle size range
Different finished products can be obtained by adjusting the discharge port (15-100mm):
Coarse crushing mode (50-100mm): suitable for primary crushing;
Fine crushing mode (15-50mm): used in conjunction with secondary crushing equipment.
Capacity performance
The output under standard working conditions is 16-35m³/h, which can be increased to 25-70t/h after optimizing the discharge port;
90% of new equipment can still maintain stable output when the discharge port is 25-60mm.
Finished product quality
Using the pure extrusion crushing principle, the finished products are mostly cubic, and the needle-like content is less than 10%. However, the actual effect is affected by the degree of wear of the jaw plate, and the tooth pitch size needs to be checked regularly.
3. Optimization suggestions for PEX350×750 jaw crusher
Regularly monitor voltage stability to avoid capacity reduction due to insufficient voltage;
New equipment needs to be run-in at the initial stage of operation. It is recommended that the capacity in the first month be controlled at 80% of the rated value;
For high-hardness materials, manganese steel jaw plates can be used to extend the service life.
