Sand shaping machine

Description

Sand making machine is also called sand making machine, which is the fourth generation of impact sand making and shaping machine optimized on the basis of previous sand making equipment. It has the characteristics of high energy saving efficiency, low operating cost, long service life, green environmental protection, etc., and is widely used in many departments such as sand and gravel factories, building materials, highways, railways and so on.

Performance Advantages

• 1, deep cavity impeller, large processing capacity: the crushing of medium hard, extremely hard and abrasive materials such as pebbles, quartzite, sandstone, basalt, silicon carbide, gold steel sand, sintered bauxite and other materials, the crushing rate is higher than that of similar equipment, and the output is larger.
• 2, green environmental protection: HVI sand shaping machine adopts water seal, its structure design is reasonable and compact, narrow the gap between the parts, prevent the entry of dust. At the same time, the smart air circulation of the broken material in the vortex chamber in the machine eliminates the pollution of dust, makes the environmental pollution smaller, and realizes the environmental protection production.
• 3, the core wear-resistant material, durable: HVI sand shaping machine adopts domestic mature and stable production technology, highly wear-resistant impact materials, better impact Angle design, can reduce the friction between materials and wear-resistant parts, effectively extend the service life of the sand making machine.
• 4, reasonable choice of crushing principle, low energy consumption: HVI sand shaping machine discharge gap has adjustment function, to ensure the uniform and stable discharge particle size, excellent particle shape, with fine crushing, coarse grinding function, small energy consumption.
• 5, lubrication mode - thin oil type and grease type modular design, can achieve the whole interchangeable.

Working Principle

The motor drives the bearing cylinder to drive part of the main shaft to rotate at a high speed, while the rotor rotates at a high speed along with the main shaft. Materials entering the impeller are accelerated by the impeller and then sprayed into the crushing chamber, where they collide with the lining materials formed in the crushing chamber and interact with each other to convert the acquired kinetic energy into the energy required for crushing or shaping materials. The material circulating in the crushing chamber for many times is broken and shaped several times under the action of the surrounding gas eddy currents to achieve continuous crushing and shaping, and the required finished material is discharged from the lower part of the body. This crushing method is "stone beating stone", which is mainly used in the plastic crushing of stone.

It is also equipped with the "stone beating" crushing method, which is different from the stone beating stone: after the material is sprayed out of the rotor, the impact block installed in the crushing chamber is impacted, the energy obtained by the material is accelerated into the energy required for the collision and crushing of the counter block, and the material is directly discharged from the lower part of the body after the impact, this crushing method is mainly suitable for crushing work occasions.

Question&Answer

Q：Why are some sand making machines single motor and some double motor? Isn't the energy consumption of dual motors greater?

A：This problem needs to be viewed relatively, first of all, single motor driven sand making machine and double motor driven sand making machine are different types of sand making machine, in terms of type, single motor driven sand making machine is usually vertical sand making machine and counter sand making machine. The double motor drive refers to the impact sand making machine (the type that is widely used in the current market), the design principle and design structure of the impact sand making machine itself determines that it can use the double motor drive, which has a higher kinetic energy, therefore, it has a better use effect in crushing hard materials.

Q：Impact sand making machine has two crushing methods: "stone beating stone" and "stone beating iron". How to choose in production?

A：The choice of crushing method should be determined by the nature of the material and the purpose of sand making. "Stone beating stone" is suitable for materials with large abrasive properties above medium and hard, such as basalt, quartz, granite, etc., and the finished product has better grain shape and slightly more powder content under the working condition of "stone beating stone"; "Stone blacksmithing" is suitable for small abrasive materials below medium hard, such as limestone, dolomite, etc., in the case of "stone blacksmithing" work, the crushing efficiency is higher, the wear cost of the protective plate is higher, and the finished grain type is slightly worse (the most serious wear in the process of "stone blacksmithing" should be the anvil). In addition, "stone beating stone" is suitable for shaping, "stone beating iron" is suitable for sand making, and the output is relatively small.

Q：What are the wearing parts of the impact sand making machine?

A：Standard wearing parts: cylindrical roller bearing, deep groove ball bearing, thrust ball bearing, expansion sleeve, conveyor belt, oil seal, O-ring seal.
