Sand making machine is a very important machine equipment in the process of sand and stone production. Sand making machine is an important mechanical equipment to process and molding sand and gravel. With the development of the horizontal construction industry and road construction engineering, the demand for sand making machine is greatly increased. It reminds the majority of users to pay attention to the possible use of sand making machine. The overload operation of the sand making machine will result in some problems in the sand making machine.

How does a sand making machine prevent the problem of overload? The user can set the low strength and easy break point of the elbow plate, that is, when the sand making machine is overloaded, the stress sensitive area of the elbow plate is broken by itself because of the sharp increase of stress to the limit value, and the power transfer is cut off to prevent the machine from damaging. This is one of the important methods for self protection of the sand making machine.

Users can also use spring friction clutch, hydraulic friction clutch or safety pin, etc. this method is applied to the simple pendulum type sand making machine. This clutch not only ensures the normal working torque transmission, but also makes the transmission torque less than the allowable value. It is a very important protection part of sand making machine that sand making machine can be protected properly during load operation.

A safe and reliable hydraulic protection device is developed to replace the traditional passive protection means to ensure the continuous operation of the machine in a safe and smooth way. The hydraulic protection device is one of the important systems for the load protection of the sand making machine and is a very important part of the system.
