Vertical shaft crusher is a vertical impact crusher, commonly known as sand making machine. It is the crystallization of the wisdom and correct decision-making of experts in the development of mining machinery and equipment for many years. It is a high-energy and low-consumption equipment with international advanced level. Its performance plays an irreplaceable role in various ore fine crushing equipment. It is currently effective, Practical and reliable stone crushing machine. This product is widely used in various industries such as various ore, cement, refractory materials, bauxite clinker, emery, glass raw materials, machine-made construction sand, stone materials and various metallurgical slags.
Hx vertical impact crusher is composed of seven parts: feed hopper, distributor, vortex crushing cavity, impeller body, main shaft assembly, base, transmission device and motor.
1. Feeding hopper
The structure of the feed hopper is an inverted prism (or cylinder), and the feed port is equipped with a wear-resistant ring, and the incoming material from the feeding equipment enters the crusher through the feeding hopper.
The distributor is installed in the upper part of the vortex crushing cavity. The function of the distributor is to divert the incoming material from the feeding hopper, so that a part of the material directly enters the impeller through the central feed pipe and is gradually accelerated to a higher speed to be ejected out. Part of the material bypasses the outside of the central feed pipe and enters the outer side of the impeller in the vortex crushing chamber, and is impacted and crushed by the high-speed materials ejected from the impeller, without increasing power consumption, increasing production capacity and improving crushing efficiency.
3. Vortex crushing cavity
The structure of the vortex crushing cavity is an annular space composed of upper and lower cylinders. The impeller rotates at a high speed in the vortex crushing cavity. The material can also reside in the vortex crushing cavity to form a material lining and the crushing process of the material Occurs in the vortex crushing cavity. The wall of the vortex crushing cavity is separated by the material lining, so that the crushing effect is limited to the material, which plays a role of wear-resistant self-lining. The observation hole is to observe the wear condition of the wear-resistant block at the launch port of the impeller runner and the wear condition of the liner on the top of the vortex crushing chamber. The observation hole must be sealed tightly when the crusher is working. The distributor is fixed on the upper cylindrical section of the vortex crushing cavity. The impeller rotates at high speed to generate air flow, which forms an internal self-circulation system through the distributor and impeller in the vortex crushing cavity.
The impeller structure is a hollow cylinder made of special materials. It is installed on the upper shaft head of the main shaft assembly. It uses a conical sleeve and a key connection to transfer the pitch and rotates at high speed. The impeller is the key element of the hx vertical impact crusher. The material enters the center of the impeller from the center inlet pipe of the splitter on the impeller. The cloth cone in the center of the impeller evenly distributes the material to the various emission channels of the impeller. At the exit of the emission channel, a wear-resistant block made of special materials is installed, which can be replaced. The impeller accelerates the material to a speed of 60-75m/s and ejects it, and impacts the material lining in the vortex crushing chamber for strong self-crushing. The upper and lower runner plates are installed between the cone cap and the wear block to protect The impeller is not worn.
5. Spindle assembly
The main shaft assembly is installed on the base to transmit the power from the motor through the V-belt and support the impeller to rotate. The main shaft assembly is composed of a bearing seat, main shaft, bearing, etc.
The vortex crushing chamber, main shaft assembly, motor, and transmission are all installed on the bottom seat. The base structure has a quadrangular prism space in the middle. The center of the quadrangular prism space is used to install the main shaft assembly, and the discharge channel is formed on both sides. The dual motors are installed on the longitudinal ends of the base, and the base can be installed on the bracket or directly on the foundation.
It adopts a belt drive mechanism driven by a single motor or dual motors (above 75kw, which is a dual motor drive). The dual motors drive two motors respectively installed on both sides of the main shaft assembly. The two motor pulleys are connected with the main shaft pulley by belts to make both sides of the main shaft The force is balanced and no additional torque is generated.
According to the different working places of the crusher-outdoor or indoor operation, you can consider to configure the support or not to configure the support.
9. Lubrication system
Using Mobil automotive grease special grade centralized lubrication, the lubrication parts are the upper bearing and the lower bearing of the main shaft assembly. In order to facilitate the oil filling, the oil pipe is led to the outside of the machine for regular oil pumping.
The material enters the sand making machine from the hopper, and the material is divided into two parts by the distributor. One part enters the high-speed rotating impeller from the middle of the distributor, and is rapidly accelerated in the impeller. The acceleration can reach hundreds of times the acceleration of gravity. Then it is ejected from the three uniformly distributed flow channels of the impeller at a speed of 60-70 m/s. First, it is impacted and crushed with a part of the material that has fallen from around the distributor, and then impacted on the material lining in the vortex cavity. , It is rebounded by the material lining, impacts diagonally upwards to the top of the vortex cavity, then changes its moving direction, deflects to move downwards, and the material emitted from the impeller runner forms a continuous material curtain. Such a piece of material is subjected to two or even multiple chance impacts, frictions and grinding and crushing effects in the vortex crushing cavity. The crushed materials are discharged from the lower discharge port. In the whole crushing process, the materials will impact and crush by themselves without direct contact with the metal elements, but will impact and friction with the material lining to crush, which reduces corner pollution and prolongs mechanical wear time. The ingenious air flow self-circulation inside the vortex cavity eliminates dust pollution.
Easy-drive GT200 product field application picture:
The motor of the device is 90KW/1190RPM/170A/60HZ. When the inverter is used, you must change F3.04 from the factory value of 50HZ to 60HZ. The inverter driving this device is different from the power frequency driving this device. In addition, the F1.06 and F1.09 of the inverter must be changed from the factory value of 50HZ to 60HZ. When the equipment is normally sand making, the working current is between 180-220A. When larger sand and gravel enter the equipment to break, the current is About 220A (when not exceeding the rated sand and gravel volume of the equipment), if the sand is coarser, it is about 190A; when the inverter drives the equipment without load, the working current is about 90A. Note: This equipment must be filled with water during normal operation. Adding water from the feed port cannot replace the equipment dedicated water injection port. When adding water from the equipment dedicated water injection port, pay attention to the spray position of the nozzle and spray the inner liner. On my teeth, water is used to clean the broken teeth of the inner liner in real time. If the teeth on the inner liner are dirty or a thick layer of muddy sand, there is no breaking effect at this time, and the operating current of the equipment It's so huge that it may damage the equipment. When the inverter is in use, the selection can be selected by zooming in one gear, namely GT200-4T1100G.
When the Easydrive GT200 product is applied in the field, it meets the customer's application requirements and improves the work efficiency. The equipment can only work at 50HZ when the soft starter is used normally, and it also needs a bunch of peripheral auxiliary circuits to achieve, for example Input power phase loss, output phase loss, motor overload, overcurrent, etc., and when using the inverter drive, it can work at 60HZ (reach the rated value of the drive motor), and power input, output phase loss protection, motor overload protection, Overcurrent protection, etc. have everything, perfect to protect motors and equipment.
