Multi-hammer ultrafine pulverizer

Abstract

The invention relates to the technical field of pulverizing mechanical equipment, in particular to a multi-hammer ultrafine pulverizer. The multi-hammer ultrafine pulverizer mainly comprises a base, apower transmission system, a settling chamber, a pulverizing chamber and a discharging chamber from top to bottom in sequence; the pulverizing chamber comprises a pulverizing disc arranged on a pulverizer main shaft, an inner tooth ring arranged on the inner wall of a pulverizing chamber shell, and fixed hammers; and the pulverizing disc comprises a large disc fixed to the pulverizer main shaft,a Z-shaped connection plate, and a plurality of layers of moving hammers arranged on the large disc in the circumferential direction, and each layer comprises the multiple moving hammers. According tothe multi-hammer ultrafine pulverizer, by increasing the quantity of the hammers in the pulverizing chamber, the effective area of the inner tooth ring and the quantity of the fixed hammers, the track, in the pulverizing chamber, of an original material is optimized, the material high in crude fiber content is forcibly pushed into a pulverizing core zone so that the production capacity of the pulverizer can be improved, the crude fiber material pulverizing effect is improved, the stability of the large disc is improved, and the purpose that the required fineness can be realized only trough one time of pulverizing is achieved.

Description

technical field [0001] The invention relates to the technical field of pulverizing machinery and equipment, in particular to a superfine pulverizer with multiple groups of hammerheads. Background technique [0002] At present, the requirements for the crushing particle size of raw materials for aquatic feed are getting higher and higher, and the quality of feed raw materials is getting lower and lower. Raw materials that are difficult to crush are used in large quantities (such as rice bran, rapeseed meal, squid paste), and the difficulty of crushing is getting higher and higher (fiber High fiber content, small fiber bulk density, and not easy to be hit by the hammer of the pulverizer during the whole crushing process), resulting in the current ultrafine pulverizer's low output per hour and high energy consumption; under the background of the Sino-US trade war, the use of soybean meal The increase in cost and the reduction in the use of soybean meal have led to an increase i...

AI Technical Summary

Problems solved by technology

[0007] 2. Crude fiber materials are difficult to crush. The raw materials of coarse fiber quickly pass through the crushing area under the action of wind force, and the hammer head has a weak crushing effect on them, so the crushing effect on materials with high crude fiber content is poor.

[0008] 3. When the required fineness is achieved with only one crushing, the accessories are severely worn and the cost of accessories is high
