Embodiment 1

[0013] Embodiment 1: A ball milling method in the production process of aluminum ceramic balls, the specific operation steps are as follows:

[0014] 1. Raw bauxite crushing: The raw bauxite entering the factory is transported from the stockyard to the raw bauxite crushing workshop by the loader, and is crushed by a PE400×600 jaw crusher with a roller crusher. After crushing, the raw bauxite is The lumpiness is controlled within 40mm. The crushed raw bauxite is transferred to the kiln loading bin of the bauxite rotary kiln through the belt conveyor, and evenly transported to the rotary kiln by the feeder under the bin for calcination.

[0015] 2. Rotary kiln calcination: The crushed raw bauxite is calcined in a 3.0×50m diameter rotary kiln. After the calcination process, the disintegration and fragmentation, the lumpiness of the cooked bauxite out of the kiln is controlled below 25mm, The cooked bauxite is directly transported to the cooked bauxite shed through the plate chain...

Embodiment 2

[0018] Embodiment 2: a ball milling method in the production process of aluminum ceramic balls, including the following specific production steps:

[0019] 1. Raw bauxite crushing: The raw bauxite entering the factory is transported from the stockyard to the raw bauxite crushing workshop by the loader, and is crushed by a PE400×600 jaw crusher with a roller crusher. After crushing, the raw bauxite is The lumpiness is controlled within 40mm. The crushed raw bauxite is transferred to the kiln loading bin of the bauxite rotary kiln through the belt conveyor, and evenly transported to the rotary kiln by the feeder under the bin for calcination.

[0020] 2. Rotary kiln calcination: The crushed raw bauxite is calcined in a 3.0×50m diameter rotary kiln. After the calcination process, the disintegration and fragmentation, the lumpiness of the cooked bauxite out of the kiln is controlled below 25mm, The cooked bauxite is directly transported to the cooked bauxite shed through the plate...

Abstract

The invention discloses a ball-milling method used in the aluminum porcelain ball production process and belongs to the technical filed of aluminum porcelain ball production and processing. The ball-milling method specially comprises the manufacturing steps of raw bauxite crushing, calcination in a rotary kiln, material preparation and ball milling. The problems of high investment, lots of auxiliary devices, the stricter requirements for the moisture content of raw materials, low raw material utilization rate and the like in an existing ball-milling mode are effectively solved. The ball-milling method has the advantages that an intermittent ball-milling machine wet process is adopted for ball milling, an air path system is not used, the number of the auxiliary devices is small, no dust removal device is used, mud and high-moisture-content materials can be processed, the investment is 8% or below lower than that for existing dry-process ball milling, and meanwhile sintering process waste is added in the ball milling process for grinding, so that the material utilization rate is improved by 5% or above.

Description

technical field [0001] The invention relates to a ball milling method, in particular to a ball milling method in the production of aluminum ceramic balls, and belongs to the technical field of production and processing of aluminum ceramic balls. Background technique [0002] The natural ball stones or artificial pebbles used in the Central Plains process of my country's building ceramics industry are gradually banned due to environmental protection. At the same time, the performance of natural ball stones is unstable. During the use of ceramic balls, the ball material is relatively large, and the ball milling efficiency is poor. A new China's grinding ceramic balls began to be produced and gradually replaced natural ball stones and ordinary ball stones, that is, aluminum ceramic balls. Compared with natural stone balls and ordinary ceramic balls, the wear resistance of aluminum ceramic balls is increased by 20-40 times, the grinding efficiency is increased by 40-60%, the effi...
