An energy-saving, low-carbon and environmentally friendly European-style pulverizer

Abstract

The invention relates to an energy-saving low-carbon environment-friendly European-type grinding machine comprising an analytical machine on the upper part of a host machine, wherein the lower part of the host machine comprises an upper machine body, a middle machine body and a lower machine body; a discharge hole is formed in the top end of the upper part of the main machine; an airflow isolation loop is arranged on the lower part of the host machine; fine powder sending space is formed between the airflow isolation loop and the machine bodies of the lower part of the host machine; a feeding hole is installed in the outer side of the middle machine body; an air inlet is arranged in the lower machine body; a main shaft transmission device is installed in the middle machine body; the main shaft transmission device comprises a host machine belt wheel and a belt wheel transmission shaft; the host machine belt wheel is installed at the outside of the middle machine body; one end of the belt wheel transmission shaft is connected with the host machine belt wheel; the other end of the belt wheel transmission shaft is engaged with the other conical gear of the main shaft; a combined-type grinding roller lifting frame is installed on the main shaft; a cross arm shaft is installed on the combined-type grinding roller lifting frame; the upper end of a long-arm grinding roller shaft assembly is suspended on the cross arm shaft to form a movable fulcrum; a grinding roller capable of performing autogiration is installed at the lower end of the long-arm grinding roller shaft assembly; and a grinding ring with the position corresponding to that of the grinding roller is installed on the lower machine body. The energy-saving low-carbon environment-friendly European-type grinding machine is high in grinding efficiency, convenient to examine and repair and install, and long in service life, and a finished product produced by the energy-saving low-carbon environment-friendly European-type grinding machine is wide in particle size range.

Description

technical field [0001] The invention relates to the field of mining machinery, in particular to an energy-saving, low-carbon and environment-friendly European-style pulverizer. Background technique [0002] The pulverizer is a commonly used grinding equipment, which is suitable for processing various non-metallic ore powders, and it is a heavy industrial machinery with a large volume, complex structure, and high manufacturing cost. Streamlining the structure and reducing costs has become the key to the design. Among them, the host of the mill is the key to milling. The design of the host of the mill directly affects the efficiency of powder selection, so the structural design of the host is very important. [0003] Existing pulverizers have the following defects: [0004] 1. The motor that drives the main shaft is mainly arranged at the lower end of the lower body, and the motor is mainly fixed by installing a motor frame at the lower end of the lower body. Once the motor ...

AI Technical Summary

Problems solved by technology

[0004] 1. The motor that drives the main shaft is mainly installed at the lower end of the lower body, and the motor is mainly fixed by installing a motor base at the lower end of the lower body. Once the motor fails and needs to be repaired, it is very inconvenient to disassemble the motor

In addition, the fixation of the motor frame needs to be treated with trench foundation, which further increases the difficulty and cost of equipment installation

[0005] 2. The flow space in the grinding chamber of the body is relatively limited, which is not conducive to the separation, extraction and grinding of materials, and is also not conducive to improving the product fineness and output, because the flow space in the grinding chamber of the body is small, it is easy to generate heat during work, and at the same time increases energy. wear of consumables and wearing parts (e.g. rollers, rings and blades)
