Aluminum oxide encrustation block crushing production line device with multiple end product particle sizes

Abstract

The invention relates to an aluminum oxide encrustation block crushing production line device with multiple end product particle sizes. The aluminum oxide encrustation block crushing production line device is composed of a crusher, a first iron remover, a conveyer, a raw material bin, a gate valve, a vibrating feeder, a pulverizer, a first electric butterfly valve, a second electric butterfly valve, a bucket lift, a second iron remover, a cylinder sieve, a bag type dust collecting device, an air exhaust device, a first pressure transmitter, a temperature transmitter, a second pressure transmitter, an end product bin, and another gate valve. The crushing production line device enables materials to go through primary crushing processing through a production line. Sizes of feeding particles are smaller than or equal to 300mm, and sizes of discharge particles can be from 1mm to 10mm. The electric butterfly valves, the pressure transmitters and the temperature transmitter are arranged on the production line so as to be favorable to adjustments of the production line, timely monitor pipeline pressure and temperature of the production line, and know operation conditions of the production line at any time. The aluminum oxide encrustation block crushing production line device is simple in structure, easy to improve, convenient to use, energy-saving, efficient, safe, and environment-friendly.

Description

technical field [0001] The invention relates to a crushing production line device for alumina crust blocks, in particular to a crushing production line device for alumina crust blocks with various particle sizes. Background technique [0002] In recent years, the electrolytic aluminum industry has developed rapidly. Statistics show that since 2001, the domestic demand for electrolytic aluminum has grown at a rate of 1 million tons per year; by the end of 2003, the production capacity of electrolytic aluminum had reached 8.34 million tons; by 2008, electrolytic aluminum The production capacity has reached 12.5 million tons. With the rapid growth of electrolytic aluminum production in my country, the amount of alumina crusts left over by electrolytic aluminum enterprises in production has also increased. However, the research and development status of domestic alumina crust crushing technology is limited to the rectification and improvement of individual equipment. For exampl...

Problems solved by technology

[0004] 2. Use Raymond mill to grind alumina crust into powder, but there are problems of low efficiency and poor material control, which are mainly reflected in (1). When the hardness of alumina crust is high, Raymond mill The grinding speed is too slow, and the Raymond mill itself wears seriously; (2), when the water content of the alumina crust is large, it is easy to stick in the Raymond mill, and it is also easy to block during the feeding and conveying process , resulting in a reduction in the production capacity of the Raymond mill; (3), when the fineness of the alumina crust block is required to be high, the Raymond mill has a small grinding capacity; (4), before the alumina crust block is ground When mixed with fine powder, it needs to be sieved once in advance; otherwise, these fine powders are easy to adhere to the Raymond mill and affect the transportation of the ground material; (5), the structure of the Raymond mill itself, the hammer head, the jaw plate The wear resistance of the Raymond mill determines the grinding capacity of the Raymond mill to a certain extent, so it is difficult to adapt to the development requirements of large industries

[0006] This shows that the above-mentioned existing alumina crust block crushing production line device obviously still has inconvenience and defects in structure and use, and needs to be further improved urgently

In order to solve the above-mentioned problems, the relevant manufacturers have tried their best to find a solution, but for a long time no suitable design has been developed, and the general product has no suitable structure to solve the above-mentioned problems. This is obviously the relevant industry. Urgent problem
