Sand making machine, also known as energy-saving composite fine crusher, integrates the advantages of hammer crusher, impact crusher and impact crusher, and gradually replaces the original vertical impact crusher in the machine-made sand market. Features and advantages: The crusher adopts a super-large arc crushing cavity and uses the principle of "stone-to-stone" self-impact crushing. The crushing chamber is a screening chamber with a grate. It is very important that our company has invested a huge sum of money to develop a "once and for all" special hammer for fine crushing, which has achieved a revolutionary breakthrough of "breaking the jaw with a hammer" and completely realized the low-cost operation in fine crusher. The output of vertical impact crusher can not be adjusted; The spindle speed of the equipment is high and the maintenance cost is high. Usually, once there is a problem, you can only return to the factory for repair. The powder content of the discharged material is large; The finished product rate of discharging is low, accounting for only 30%-40% of the production capacity; Large power consumption, driven by double motors, more than twice that of fine crusher. VI vertical impact crusher, commonly known as sand making machine. It is the crystallization of the wisdom and correct decision-making of mining machinery and equipment developed by experts of our company for many years. It is a kind of high-energy and low-consumption equipment with international advanced level, and its performance plays an irreplaceable role in all kinds of ore fine crushing equipment. It is the most effective, practical and reliable crusher at present. Our company has been producing sand making machines since 200 1, which has achieved excellent market share in the national market, improved product performance, won the trust of customers and won the recent customers at home and abroad. This product is widely used in various industries such as ore, cement, refractory, alumina clinker, emery, glass raw materials, machine-made building sand, stone and various metallurgical slag. Hx vertical impact crusher consists of seven parts: feed hopper, distributor, vortex crushing chamber, impeller body, spindle assembly, base, transmission device and motor.

1. Feed hopper

The structure of the feed hopper is inverted frustum (or cylinder), the feed inlet is provided with a wear ring, and the incoming materials from the feeding equipment enter the crusher through the feed hopper.

2. Dealers

The distributor is installed at the upper part of the vortex crushing cavity, and its function is to shunt the materials from the feed hopper, so that some materials directly enter the impeller through the central feed pipe and are gradually accelerated and thrown out at a higher speed, while the other materials bypass the outside of the impeller in the vortex crushing cavity and are impacted and crushed by the high-speed materials thrown out by the impeller, without increasing power consumption, increasing productivity and improving crushing efficiency.

3. Eddy current crushing cavity

The structure of vortex crushing chamber is an annular space composed of upper cylinder and lower cylinder. The impeller rotates at high speed in the vortex crushing cavity, and the material can also stay in the vortex crushing cavity to form a material lining. The crushing process of materials takes place in the vortex crushing cavity, and the wall of the vortex crushing cavity is separated by the material lining, so that the crushing effect is limited in the material and plays the role of wear resistance and self-lining. The observation hole is used to observe the wear of the wear block at the launch port of the impeller wheel and the wear of the lining plate at the top of the eddy current crushing cavity. When the crusher is working, the observation hole must be sealed tightly. The distributor is fixed on the upper cylindrical section of the vortex crushing cavity. The impeller rotates at high speed to generate air flow, and the air flow forms an internal self-circulation system through the distributor and the impeller in the vortex crushing cavity.

4. Impeller

The impeller structure is a hollow cylinder made of special material and installed on the shaft head at the upper end of the spindle assembly. The conical sleeve is connected with the key to transmit the distance of the knob and rotate at high speed. Impeller is the key component of hx vertical impact crusher. Materials enter the center of the impeller from the central feed pipes of some feeders on the impeller. The distribution cone in the center of the impeller distributes the materials evenly to all the discharge channels of the impeller, and the outlet of the discharge channel is equipped with wear-resistant blocks made of special materials, which can be replaced. The impeller accelerates the material to the speed of 60-75m/s and throws it out, which impacts the material lining in the rotating crushing cavity and carries out strong self-crushing. The upper and lower runner plates are installed between the conical cap and the wear block to protect the impeller from wear.

5. Spindle assembly

The spindle assembly is installed on the base, transmits the power from the motor through the V-belt, and supports the rotating motion of the impeller. The spindle assembly consists of bearing seat, spindle and bearing.

6. Foundations

The eddy current crushing cavity, the spindle assembly, the motor and the transmission device are all installed on the base. The structure of the base is a quadrilateral space in the middle. The center of the quadrangular space is used to install the spindle assembly, and the discharge channels are formed on both sides. Double motors are installed at both longitudinal ends of the base, and the base can be installed on the bracket or directly on the foundation.

7. Transmission equipment

Belt transmission mechanism driven by single motor or double motor (above 75kw, driven by double motors). Two motors driven by double motors are respectively installed on both sides of the spindle assembly, and the pulleys of the two motors are connected with the pulleys of the spindle through belts, so that the forces on both sides of the spindle are balanced and no extra torque is generated.

8. Bracket

According to the different working places of the crusher-outdoor or indoor, it can be considered whether to configure the support.

9. Lubrication system

Mobil vehicle grease is used for ultra-centralized lubrication, and the lubrication parts are the upper bearing and the lower bearing of the spindle assembly. In order to facilitate oil injection, the oil pipe is led out of the machine for regular oil injection of the oil pump. This series of sand making machines are suitable for the crushing and molding of soft or medium hard and extremely hard materials, and are widely used in various ores, cement, refractories, alumina clinker, emery, glass raw materials, machine-made building sand, stone and various metallurgical slags, especially for high-hard, extremely hard and wear-resistant materials such as silicon carbide, emery, sintered bauxite and fine sand.
