Jaw crushers are the most common crushing equipment in sand and gravel aggregate yards, and are widely used in many fields such as mining, smelting, building materials, roads, railways, water conservancy and chemical industries. When the jaw crusher is performing crushing work, if the feeding method and feeding time are incorrect, it will cause damage to the crushing parts, and cause unexpected situations during the operation of the equipment, making the machine unable to work normally and delaying the progress of the construction. The following is Let us introduce the requirements and precautions for jaw crusher feeding.
1. An important parameter of the jaw crusher is the maximum feeding size. Generally, the maximum material size of the jaw crusher is greater than or less than 75%, so the maximum size of the feed material should not be greater than 0.85 times the width of the feed port, otherwise it will reduce the output of the machine or damage the crushing parts of the machine. Therefore, strictly controlling the particle size of raw materials is one of the important prerequisites for the normal operation of the jaw crusher.
2. When the jaw crusher is crushing, it is very important to feed evenly. If the machine feeds suddenly large and small during crushing, the machine parts cannot be adjusted in time and the parts of the equipment will be damaged; There should be professional feeding equipment for feeding, and the angle of feeding materials should not be too steep, let alone directly put into the crushing cavity, so as not to damage the movable and fixed jaws.
3. The size of the ore discharge port of the jaw crusher determines the processing capacity of the equipment. Jaw crushers are often used as primary crushing equipment, and the size of the discharge port should be based on the optimal input particle size of the secondary crushing, and the size of the discharge port cannot be increased or decreased arbitrarily.
4. In the process of feeding, it should be noted that if iron or non-broken materials enter the machine, stop the machine and remove them immediately, because these objects may cause jaw crusher blockage, overload and other failures.
