Henan Hongxing Mining Machinery provides the sand making machine with perfect technology for various industries, such as the steel, cement, hydropower, and other large-scale projects. The sand making can achieve multi using purposes in the mining industry, which can promote the harmony and rapid development of the various industries. In the actual use, we should deeply and correctly grasp the operation and maintenance technologies for the sand making machine. Before the start, you should check if there are foreign bodies in the vortex crushing cavity to prevent the foreign bodies from blocking the runner of the vane wheel and the central feeding. We should feed the materials according to the particle size of the materials. When you find the large pieces of the materials, you should remove them in a timely manner and you should stop feeding straightaway. The discharging belt conveyor should stop the operation of the sand making machine. The rotating speed of the sand making machine is very high. The throwing speed of the materials by the vane wheel is 60m/s to 70m/s. Therefore, we should check if the observation door is closed tightly before starting the sand making machine to avoid the damage to the machine. The sand making machine produced by Henan Hongxing Mining Machinery is professional equipment for the production of the sand and aggregates. The sand and aggregates produced by the sand making machine comply to the construction standard. In addition, the sand making machine produced by Henan Hongxing Mining Machinery can be used for crushing various of stones, such as the granite, basalt, limestone, river gravel and the industrial tailings. All the stone can be produced to the artificial sand. Henan Hongxing Mining Machinery specially uses the sealed treatment and reduces the damage to the operators by isolating the noise. The particles produced by the sand making machine are in good shape. The equipment is installed flexibly so that the operation becomes easy and the installation becomes convenient. In the process of internationalized road, Henan Hongxing will continuously take great efforts on the improvement of the inner structure of the products and occupying the international high-tech sales territory.
