The performance of sand making machine directly affects the quality and output of sandstone products. In order to improve the grinding rate of sand machine, the equipment with good performance is the foundation. The adaptability of material performance and working parameters of sand making machine also determines the finished sandstone. An important factor. How to choose the sand making equipment, the selection criteria of different users are different according to the needs of customers.

In general, the whole center feeding is mainly made of stone iron, which is generally used to make sand with low output; while the central feeding with waterfall feeding is the combination of stone tapping iron and stone striking stone, which is generally used for shaping, with high yield.

It is suitable for medium hard materials with high abrasiveness, such as basalt. In the crushing process, the material ejected from the wheel has impact on the material lining, and does not directly contact with the metal components of the equipment, so as to reduce iron consumption and maintenance time. Under the working condition of stone striking, the grain shape of finished product is good.

It is suitable for medium hard and low abrasive materials, such as limestone. The crushing efficiency is high under the working condition of stone striking iron.

1. Performance of sand making equipment: the performance of equipment directly affects the quality of gravel, including the selection of equipment type and specification, and the combination of material properties.

From the model of sand machine, in addition to the traditional sand machine, there are different sand making equipment, their working performance is different.

In addition, different manufacturers have different levels of technical mastery of sand making machines. The performance of sand making equipment produced by different manufacturers will be different.

2. Material characteristics: the working parameters of sand making machine need to be adjusted according to the physical and chemical properties of materials. The higher the matching degree between the two, the better the working performance of sand making equipment, the better the quality of finished products and the higher grinding rate. If there is a big difference between the material parameters of the material and the working parameters of the sand making machine, such as the hardness and water content of the material, which are not suitable for the predetermined parameters of the sand making machine, the use of the grinding speed sand making machine will be greatly reduced.

3. Production environment: due to the source of materials and other reasons, the production environment of gravel aggregate is different and complex.

In the field of dry powder sand making, the requirement of sand making machine is very high. The material enters the crusher and is even subjected to two times of impact from the crusher and into the crusher. Materials are divided into 20 mesh or smaller. The material itself is crushed to reduce angular contamination. The hammer and lining in the sand machine are made of new wear-resistant material. As for limestone, the life of the hammer is about half a year, which reduces the cost to the customer.
