Adjustable particle size circulation stone crushing device

Abstract

The invention discloses an adjustable particle size circulation stone crushing device. The adjustable particle size circulation stone crushing device comprises a machine body, a feeding barrel, a driving crushing roller and a driven crushing roller. A crushing cavity is formed in the machine body. The feeding barrel is arranged at the top end of the machine body, and the part, below the feeding barrel, of the crushing cavity is internally provided with the driving crushing roller and the driven crushing roller. One end of the driving crushing roller is connected with a motor A through a speedreducer. A discharging port A is formed below the driving crushing roller and the driven crushing roller. A filter sieve is arranged at the upper end of the discharging port A. A supporting frame is arranged on the left side of the machine body and provided with a lifting device. A motor B is connected to the lower end of the lifting device. The output end of the motor B is connected with a rotation shaft through a connector. A crushing tooth disc is arranged on the rotation shaft, a fixing crushing tooth ring is fixed to the part, on the outer side of the crushing tooth disc, of the machine body, and the inner diameter of the fixing crushing tooth ring is in an inverted cone shape with the large upper part and the small lower part. A support is arranged below the crushing tooth disc, a vibration plate is arranged on the support, a spring is arranged between the vibration plate and the support, and an elevating device is arranged on one side of the vibration plate.

Description

technical field [0001] The invention relates to the field of stone crushing devices, in particular to a circulating stone crushing device with adjustable particle size. Background technique [0002] Mining machinery equipment refers to machinery specialized in mining, mineral processing, and prospecting. A large number of cranes, conveyors, fans and drainage machinery used in mining operations are collectively referred to as mining machinery and equipment. The crusher is a common mining equipment. The crusher mainly relies on the impact energy to complete the crushing operation. When the crusher is working, the motor drives the rotor to rotate at a high speed, and the material enters the crusher cavity evenly. The impact, shearing and tearing of the material cause the material to be broken. The crusher can break the ore into small particles, which is convenient for processing and transportation. Modern crushers have many defects. For example, modern crushing equipment can on...

The crusher is a common mining equipment. The crusher mainly relies on the impact energy to complete the crushing operation. When the crusher is working, the motor drives the rotor to rotate at a high speed, and the material enters the crusher cavity evenly. The impact, shearing and tearing of the material cause the material to be broken. The crusher can break the ore into small particles, which is convenient for processing and transportation. Modern crushers have many defects. For example, modern crushing equipment can only For one-time crushing, the particle size of the crushing is not small enough. To achieve the target particle size, multiple crushing is often required, and the efficiency is very low. At the same time, after the modern crusher crushes the ore, the particle size of the ore is different, and the modern device lacks effective means. Separation of these ores of different particle sizes
