A jaw crusher with a feed size of up to 700 mm is suitable for the primary crushing of hard rock. When selecting a model, take into account the size of the feed material, the compression force required for the rock’s hardness, and the required throughput. During operation, warm up the mechanism before the first start-up, do not feed in raw material larger than 700 mm, check the jaw plates for wear and tighten the fastenings. Carry out a routine inspection every 30 working hours, clean the crushing chamber and check the bearing lubrication to extend the service life.
A jaw crusher with a feed opening of up to 700 mm is a reliable tool for the primary processing of hard rock. To choose the right model and avoid operational problems, you simply need to consider three key criteria that guarantee the equipment’s efficiency and long service life.
When selecting equipment, first and foremost check that the maximum feed size matches the dimensions of your raw material, and ensure that the crusher’s crushing force is appropriate for the hardness of the rock to be processed; and also assess the required throughput to ensure the equipment is not operating at full capacity.
Before starting the machine for the first time, be sure to warm it up whilst idling; do not feed in raw materials larger than the specified limit of 700 mm, check the wear on the jaw plates regularly, and tighten the fastenings in good time to prevent vibration-related failures.
Carry out a routine inspection of all components every 30 working hours, clear the crushing chamber of any remaining raw material at the end of each shift, and check the level and quality of the bearing lubricant; this will help avoid unscheduled downtime for repairs and save on maintenance costs.
