A key task of the sand production line is to coarsely crush the materials. For the coarse crushing of stone, our common crushers mainly include jaw crushers. Jaw crushers are widely used coarse crushing equipment. The main task is to crush The stone is initially crushed. The main advantages of the jaw crusher are high output and reasonable price. After the initial crushing, the content of needle-like pieces of the stone is small, which is a good equipment for coarse crushing.

After the material is coarsely crushed, the next step is to finely crush the material. Generally, the equipment for medium and fine crushing in the sand production line is mainly the impact crusher and the cone crusher. For the sand making machine, the sand making machine in our country is also In continuous improvement and improvement, there are roughly two types of sand making machine equipment, one is a high-efficiency vertical shaft impact crusher and the other is a single impact sand making machine. For different materials, we can choose different types of sand making machines. Sand machine equipment.

Because of the different raw materials in the mine, the crusher equipment selected is also different. For example, for coal-based raw materials, we can choose a hammer crusher or a pair of roller crushers when configuring. It is necessary to configure different ore materials. Investors value high-efficiency, professional and energy-saving production lines. Faced with the configuration problem of the sand production line, the finished stones produced by the configured sand production line have a hexagonal appearance, which is very suitable for domestic high-standard engineering use. The use of a new hydraulic impact crusher as the secondary crushing equipment of the sand production line, combined with the hammer head and liner made of foreign efficient wear-resistant materials, increases the wear resistance of the equipment to a greater extent; sand production line It is composed of vibrating feeder, jaw crusher, impact crusher, vibrating screen, etc. The specifications and models are selected according to the characteristics, quality and output of the stone, and dust removal devices can also be equipped according to requirements.

The belt coupling of the reversible sand making machine is not larger than 0.3 mm. It should be carried out after the installed drive shaft and the gearbox of the reversible sand making machine. The high speed shaft of the gearbox and the motor shaft are not concentric. It shall not be larger than 0.15 mm, and the belt coupling shall not be larger than 0.3 mm. The reversible sand making machine often affects production due to motor failure during use. The main failure phenomena include: stator and rotor core failure inspection and repair, and the rotor is composed of mutually insulated silicon steel sheets, which are the magnetic circuit part of the motor.

The damage and deformation of the stator and rotor cores are mainly caused by the following reasons: excessive wear or poor assembly of the bearings of the reversible sand making machine, causing friction between the stator and rotor, causing damage to the surface of the core, and causing short circuits between the silicon steel sheets. The iron loss of the motor increases, which makes the motor temperature rise too high. At this time, use fine files and other tools to remove the burrs, eliminate the short circuit of the silicon steel sheet, clean it up, apply insulating paint, and heat and dry it.

Excessive force was used when removing the old winding, which caused the stolen slot to skew and open outward. At this time, use needle-nose pliers, wooden hammers and other tools to trim, reset the tooth slot, and add hard insulating materials such as blue shell paper and bakelite between the silicon steel sheets with gaps that are not easy to reset. The surface of the iron core is corroded due to moisture and other reasons. At this time, it needs to be polished with sandpaper, and then coated with insulating paint. The combination between the iron core and the base is loose, and the original positioning screws can be tightened. If the positioning screw fails, re-drill the positioning hole on the machine base and tap it, and tighten the positioning screw.
