VIBRATING CRUSHER
Technical Field
The Invention relates to a crusher and particularly to a vibrating crusher. Background Art
In mining, cement, power and chemical industries, the traditional intermediate and fine crushing solutions such as the roll squeezer, vertical crusher, cone crusher, hammer crusher and ball grinder have many shortcomings and restrictions as high energy consumption, serious abrasion, frequent maintenance and insufficient efficiency. In cement industry, the ball grinder is additionally used as a crusher in most cases, resulting in low production efficiency, high energy consumption, high consumption of lining plates and frequent maintenance. With the advent of the principle of "more grinding and less crushing" and the pre-grinding process, the production efficiency of the ball grinder has been largely improved. The current main pre-grinding device of ball grinder such as high-pressure roller press has many shortcomings as high energy consumption, heavy investment and serious abrasion, restricting the popularization of the pre-grinding process. In mine industry, the common use of the cone crusher, hammer crusher, vertical crusher even ball grinder as intermediate and fine crushing devices may cause high expenses due to the shortcomings as serious abrasion, high energy consumption and frequent maintenance. It can be seen that the intermediate and fine crushing solutions in all industries around the world have an urgent need of an excellent device to bring in a revolutionary break-through.
As two different processes, grinding is mainly generated from the shear stress generated by relative displacement between materials and metals, while crushing is mainly generated from the pressure stress generated by collision between materials and metals. The grinding and crushing effects often occur synchronously in the operation of traditional equipment. In the process of abrasion, the crush resistance of metal is much higher than its shear resistance. On a micro level, the largest damage to the metal is the peeling of metal particles caused by shear stress which
AUP
SPECIFICATION 2/9 2015101883 03 Μ 2015 forms cutting to the metal surface by materials. Therefore, traditional crushers have the shortcomings as large consumption of wear-resistant materials and frequent maintenance.
The characteristic of vibrating device is high-frequency vibration. The high-frequency vibration of crushing medium enables an extremely short contact between the material and the medium, almost ignoring the displacement between the two and thus avoiding the cutting effect of the material to the metal medium. The crushing is achieved through the impact force brought by vibration, thus the metal medium only needs to bear pressure stress with the largest possibility, maximizing the performance of the metal material and avoiding metal abrasion to the largest extent. The vibration frequency is large, but the amplitude is small; therefore, the average linear speed of the device is far lower than that of any other crushing devices, further reducing abrasion greatly. It can be seen that vibrating crushing is an essential method to improve efficiency and reduce maintenance frequency of the crusher.
The machine body of the traditional vibromill or other vibrating crusher is designed as a cylinder shape with a round cross section and the length-diameter ratio is often large (above 2:1). With a cylinder-shaped machine body, the curve of both sides of the cylinder may restrict the vibration amplitude of the crushing medium and increase the energy consumption and reduce the crushing efficiency. In addition, due to the traditional movement characteristic and the overlarge low-energy region, the device cannot be upsized and the output cannot exceed 100 ton/h, which is difficult to meet the requirements of industrial production.
Summary of the Invention
The Invention is to provide a vibrating crusher with a different-shaped machine body, making materials dispersed evenly in the cavity, enabling the crushing medium of large mass to move vertically as far as possible and bring crushing 11/28/2016

The vibrating crusher of the embodiment of the Invention is described as follows by reference to Figs. 1-3.
The vibrating crusher comprises two groups of vibration exciters 3 which are connected to a motor 1 respectively, a base 7 and a machine body 9 elastically arranged on the base; the said machine body has a cavity inside which contains several crushing media 10; the said two groups of vibration exciters 3 are connected to the two ends of the machine body respectively; the rotation shafts of the vibration exciters 3 of the same group are synchronously connected with the same rotation direction via a connection shaft, and synchronizers 2 are connected between the motors corresponding to vibration exciters of different groups, making the vibration exciters of different groups rotate in reverse synchronously; a feed inlet 6 is provided at the center of the top of the said machine body and a feed outlet 4 opposite to the feed inlet 6 is provided at the bottom of the machine body; the inside of the said feed inlet is provided with a feed disperser 5 to disperse materials to be crushed to the whole cavity; the cross-section of the said machine body is U-shaped, rectangular, trapezoidal with the bottom base shorter than the top base, or ellipsoidal with longitudinal distributed long axis; the ratio of the distance between the machine body and the two groups of vibration exciters to the maximum width of the machine body cross-section is less than 2:1. A spring 8 is connected between the bottom of the said machine body and the base, making the said machine body may be elastically arranged on the base. The said spring can be a metal spring, an air spring, a rubber spring or a composite spring.
As shown in Fig. 5, the said feed disperser has a curved surface upheaved in the middle; the bottom edge is connected to the inner wall of the said machine body or arranged at the top of the feed inlet via a support; several holes or dispersing blades for feeding materials are arranged on the side faces.
As shown in Fig. 4, the said synchronizer comprises two inter-meshed driving gears

Particularly, the said crushing medium is a cylindrical alloy steel.
Fig. 6 is a schematic diagram of the chamber of the existing-art crusher and Fig.7 is a schematic diagram of the chamber of the crusher of the embodiment of the Invention. The contrast of stacking heights of the crushing media in two figures can be seen through comparison.
Fig. 8 and Fig. 9 are distribution diagrams of the materials in the machine body of the existing vibromill or crusher; Fig. 10 is a distribution diagram of material in the machine body of the crusher of the Invention, wherein, mark 11 refers to a material distribution area. The contrast of material distributions between the new and traditional cylinders can be seen through comparison.
As shown in Fig. 6, the machine body of the traditional vibromill or other vibrating crusher is designed as a cylinder shape with a round cross section; the length-diameter ratio is often large and around 3:1 (above 2:1). No matter feeding from one side and discharging from the other side or feeding from the middle and discharging from both ends, a sufficient stacking of crushing media is difficult to be obtained and the crushing efficiency is low. Therefore, the machine body shall be extended greatly to lengthen the route for crushing a grinding and extend the time for materials to stay in the crushing media and thus obtain a qualified discharging granularity. This process has largely lowered the working efficiency. Moreover, from Fig. 9, as the materials show a gradient distribution from the feed inlet to the feed outlet, most crushing media are working without any materials and 50% space of the chamber is not used. The wasting status increases the consumption of crushing media and electric power, therefore, the traditional vibromill and vibrating crusher generally have the shortcomings as low output and poor efficiency.
The improved machine body of the crusher largely increases the stacking height of
11/28/2016 B&O DocketfNJZBO 1 -2 7-AUP
SPECIFICATION 8/9 2015101883 03 Μ 2015 crushing media and thus obtains a sufficient crushing capacity, largely shortening the length of machine body and controlling the length-diameter (or length-width) ratio at or below 2:1. From Fig. 10, the materials can distributed evenly with a shorter machine body, making full use of the space in the chamber and the crushing media and further improving the efficiency of the crusher. Moreover, the shorter machine body largely shortens the moving route of materials, improving the efficiency of the crusher significantly. In addition, the synchronizer eliminates the low-energy region of the traditional vibrating device, making it possible to upsize the device. At present, the output of the model machine reaches 250-300 ton/h; through the experimental comparison, as for the traditional device, the length of the crushing chamber is 4m; the diameter is 1.3m; the filling rate of crushing medium is 40%, i.e., the stacking height of crushing medium is 520mm; the processing capacity is 60 ton/h and the installed capacity is 220KW and as for the new designed test device, the length of the crushing chamber is 2m; the diameter of chamber bottom is 1.3m (i.e., the width of chamber is 1.3m); the stacking height of crushing medium is 1.3m (the concept of filling rate is meaningless to this design); the processing capacity is 120-150 ton/h and the installed capacity is 180KW. It is proved through the data that the crushing efficiency of this design is doubled; the weight is reduced by 3-4 ton and 15%-20% energy is saved.
The width (i.e., the diameter of the machine body) of the traditional crusher is often limited and cannot be expanded optionally. From Fig. 7, the cylinder-shaped machine body of the traditional vibromill or crusher is limited by the shape, thus the stacking height of crushing media is limited by the diameter of the machine body. When the stacking height exceeds 40%, the chamber wall will impede the vibration and lower the crushing efficiency. This situation will worsen as the filling rate of the crushing media increases. In case the filling rate exceeds 80%, the device will nearly lose its crushing capacity. Therefore, the filling rate of the traditional vibromill or crusher is often controlled below 50%. Moreover, the existing of low-energy region makes the traditional devices cannot be upsized and the hourly output per device is low. As the machine body of the Invention gets rid of the limit on diameter, the stacking height of the crushing medium can be increased. As
SPECIFICATION 9/9 2015101883 03 Μ 2015 shown in Fig. 8, the stacking height can be doubled easily and the crushing efficiency can be increased by 1.5-2 times. Moreover, no matter how high the crushing medium is stacked, the chamber wall will not generate any vibration resistance and thus has no restriction on the filling rate of the crushing medium. The improved shape of the machine body may maximum the vibration amplitude of the crushing medium to maximum the crushing capacity, increase the stacking height of the crushing medium and extend the time for materials to pass through the crushing medium. The stacking height of the crushing medium has a direct influence on crushing efficiency.
In the Specification, the terms as "an embodiment", "example", "specific example" or "some examples" indicate that the particular characteristics, structures, materials or features described in combination with the embodiment or example are included in at least one embodiment or example of the Invention. In the Specification, the schematic expressions for the above terms do not necessarily mean the same embodiments or examples Moreover, the described particular characteristics, structures, materials or features may be combined in a proper way in any one or several embodiments or examples.
