Quality of sand produced by sand making machine
Commonly used are impact sand making machine, compound sand making machine, fine crushing sand making machine and other series, which are subdivided into multiple models. Because each user’s needs are different, it should be selected according to the actual situation.
1. Impact sand making machine
Scope of application: various hard and brittle materials, such as river pebbles, granite, limestone, etc.;
Working method: mainly adopts the “stone-on-rock” and “stone-on-iron” working methods. Stone-on-rock is suitable for medium-hard and above corrosive materials, such as basalt. It is mostly used for shaping and has good grain shape; stone-casting is suitable for corrosion below medium-hardness. Materials with low properties, such as limestone, have large output and high efficiency;
Performance characteristics: The impact sand making machine is developed in accordance with the actual situation of domestic sand production, integrating various crushing modes, through the design of the deep cavity impeller, the throughput is improved, the peripheral guard plate can be turned up and down, and combined throwing is used Head, only need to replace the worn parts, which can reduce the cost of use. The hydraulic cover opening device is convenient for inspection and maintenance and easy for maintenance.
Scope of application: all kinds of medium-high-hard and extra-hard materials, such as shale, glass, ceramics, bluestone, metal ore, etc.;
Working principle: using the principle of rock-on-rock;
Performance characteristics: Adopting an elastic adjustment mechanism, the non-breakable material can be automatically discharged without causing damage to the equipment, and the service life is longer than that of ordinary equipment, saving investment costs. At the same time, it is less affected by the moisture content of the material, and the moisture content can reach 8%. It is uniform and cubic, with high bulk density and minimal iron pollution.
Scope of application: various brittle materials, such as coal gangue, limestone, coke, etc.;
Working method: It is a continuous operation equipment. The material enters a crushing cavity and is crushed by the impact of the hammer on the rotor, and then enters the second fine crushing cavity to be crushed to form the required sand;
Performance characteristics: The equipment has simple structure, stable and reliable operating performance, simplified process, stable and reliable operating performance, long service life of the hammer, and the investment is less than half of the same. Its grate design can easily adjust and control the particle size of the discharged material. For materials with certain humidity and viscosity, the working conditions can be improved by adjusting the grate.
