In the field of industrial production, mining, crusher has a very wide range of applications, including mineral sizers set roller
The advantages of pressure and impact crusher are integrated, compact structure, high crushing efficiency, small crushing power consumption and highly favored.
Due to the strong demand, a variety of models appear on the market, but the crushing principle is roughly the same, are two parallel roll phase
For rotation, the material enters the V-shaped gap of the two toothed rollers, and is crushed by the relative extrusion and shear of the two toothed rollers. There is a spring device at both ends of the equipment to adjust the pressure between the two rollers, and the gap between the two teeth rollers determines the particle size of the finished material. When the material is large or unbreakable into the equipment, the tooth roller will automatically give way to protect the equipment from damage. This type of machine
The main defects of the type:
(1) The material is only pressed by a one-time roll of two rollers, that is, it becomes a finished product, and the crushing ratio is low:
(2) Due to teeth
The roller automatically gives way, so the particle size of the finished product cannot be strictly controlled:
(2) The roll teeth are small and varied, the impact capacity is weak, mainly tearing as the main crushing form, which determines that only small pieces of material can be broken.
(3) The roll teeth are simple linear uniform arrangement, while the number of rollers under force is small, the crushing efficiency is low, and the material at the feed port is concentrated, resulting in the middle of the roll teeth easy to wear or bend, affecting the life of the equipment. Therefore, according to this situation, it is urgent to develop a new mineral sizers to meet the needs of practical applications.
The technical problem to be solved is to provide a high crushing ratio mineral sizers in response to the shortcomings of the above prior art. This high crushing ratio mineral sizers can crush the material three times, with a high crushing ratio: the distance between the first and second teeth rolls is fixed, and the tooth rolls will not automatically yield and affect the particle size of the finished product; Large materials can be broken, crushing efficiency is high: the special arrangement of the roll teeth can force the bulk material in the middle part to be divided to both ends, so that the blanking on the whole tooth roller is more uniform, improve the crushing capacity. In order to achieve this technical purpose, the technical scheme adopted by the technology is as follows: A high crushing ratio mineral sizers comprises a crusher housing, a first tooth roller, a second tooth roller, a first coupling, a second coupling, a first reducer, a second reducer, a first hydraulic coupler, a second hydraulic coupler, a first motor, a second motor, a hydraulic weight item, a bolt support, a crushing beam fixing bolt, a crushing beam and a lower crushing tooth; The first tooth roller is distributed in an equal axial interval with multiple rows of roll teeth, and the starting Angle of the multiple rows of roll teeth decreases successively from the central part of the first tooth roller to both ends, so that the multiple rows of roll teeth are arranged in a V-shape; The second tooth roller is distributed along the axial equal spacing with multiple rows of roll teeth, and the starting Angle of the multi-row roll teeth decreases from the center of the second tooth roller to both ends in turn, so that the multi-row roll teeth are arranged in a V-shape: The first tooth roller and the second tooth roller are arranged in parallel in the crusher shell body, the two ends of the first tooth roller are respectively connected with the crusher shell through the bearing, the two ends of the second tooth roller are respectively connected through the bearing and the crusher shell rotation, the first tooth roller and the second tooth roller on the roller staggered arrangement; The first motor is connected with the first hydraulic coupler, the first hydraulic coupler is connected with the first reducer, the first reducer is connected with the first coupling, the first coupling is connected with the end of the first tooth roller: the second motor is connected with the second hydraulic coupler, the second hydraulic coupler is connected with the second reducer, the second reducer is connected with the second reducer
The second coupling is connected with the end of the second tooth roller shaft; The bolt support is located on the hydraulic jack, the bolt support is connected with the end plate of the broken beam through the crushing beam fixing bolt, the crushing beam is located below between the first tooth roller and the second tooth roller, and the crushing beam is connected with a plurality of lower crushing teeth.
Mineral sizers The number of each row of roll teeth on the first tooth roller is three, and the three roll teeth are evenly distributed in the circular direction of the first tooth roller; The number of each row of roll teeth on the second tooth roller is three, and the three roll teeth are evenly distributed in the circular direction of the second tooth roller. The roller teeth comprises a tooth plate, a tooth head, an impact bolt, an open elastic cylindrical pin and an adjusting gasket, the tooth plate is fixed on the first tooth roller and the second tooth roller, the tail of the tooth plate is provided with a tooth root, the head of the tooth plate is provided with a tooth plate through the hole, the tooth plate through the hole is formed by the impact bolt mounting hole and the tooth head mounting hole are interconnected. The side wall of the tooth head mounting hole is also provided with a side pin hole, the tooth head is provided with a circle of circular tooth groove for matching with the side pin hole, the impact bolt is inserted in the impact bolt mounting hole through the tooth plate and the impact bolt is matched with the tooth plate through the hole gap, the adjustment washer is set on the tail shaft of the tooth head, the tail shaft of the tooth head is inserted in the said

The pin is inserted into the circular tooth groove and the lateral pin hole. The crusher housing comprises a left end wall panel, a right end wall panel, a front side wall panel and a back side wall panel, and the left end wall panel, the front side wall panel, the right end wall panel and the back side wall panel are successively connected to form a closed rectangular crusher housing; The two ends of the first tooth roller are rotatively connected with the left end wall plate and the right end wall plate respectively through the bearing, and the two ends of the second tooth roller are rotatively connected with the left end wall plate and the right end wall plate respectively through the bearing. As a further improvement scheme of the technology, the starting Angle of the multi-row roll teeth on the first tooth roller decreases by 10° from the center part of the first tooth roller to both ends in turn: the starting Angle of the multi-row roll teeth on the second tooth roller decreases by 10° from the center part of the second tooth roller to both ends in turn: the lower crushing teeth and the crushing beam are fixed by bolts.
The mineral sizers bolt support is provided directly below the base, between the bolt support and the base is padded with adjustment gaskets, and the bolt support and the base are fixed by bolts.
