"Proper operation of a pebble sand-making machine is crucial. Feeding speed and controlling foreign matter are key to preventing malfunctions. Using a thrust plate as a safety feature, sacrificing small components to preserve the core, creates a simple and effective design. Strictly controlling feed quality ensures smooth production and reduces costs."

For pebble sand-making machines, proper operation is a major cause of malfunction. Feeding is one of the key operations, and when feeding, it's crucial to ensure the correct speed and that there are no foreign matter. Foreign matter refers to materials that the machine cannot process. What should be done if foreign matter accidentally enters the machine?

Under normal production conditions, the internal parts of a pebble sand making machine will also wear out, but this wear is normal. If foreign matter enters, a rear thrust plate is needed to protect important internal parts from damage. Generally, this plate is sometimes made of cast iron as a single piece with a slot or several small holes cut into it to reduce its cross-sectional strength. Others are cast in two pieces and then connected with screws to form a combined thrust plate. If foreign matter enters the pebble sand making machine during operation, the machine will be overloaded, transmitting force to the thrust plate, causing it to break or the screws of the combined thrust plate to shear, causing the machine to stop operating. This design principle is relatively simple and can effectively protect important internal parts of the machine. Replacing a damaged fuse is also relatively simple, and the device principle is very suitable.

In order to protect the important parts inside the equipment from being damaged, it is necessary to use a thrust plate as a safety part, that is, at the expense of the rear thrust plate to ensure the smooth production of the equipment. Although this design is simple and reasonable, in order to reduce the replacement of the thrust plate, or to reduce the delay in the production process caused by foreign matter entering the equipment and reduce the cost investment, in the production process of the river pebble sand making machine, it is necessary to strictly control the input of materials to prevent foreign matter from entering the interior of the equipment, thereby ensuring a smooth production process.
