Embodiment 1

[0067] Batching was carried out according to the pellet raw material formula shown in Table 1. The 7 kinds of raw materials, concentrate 1, concentrate 2, raw ore powder 1, raw ore powder 2, auxiliary raw material 1, auxiliary raw material 2 and auxiliary raw material 3, are added to the 7 feed bins 100 respectively. Then, using 7 quantitative feeders 200 (DEL061 quantitative feeder, Chengdu Guanghua Electric Manufacturing Co., Ltd.), the above 7 kinds of raw materials are supplied to the first conveyor according to the weight ratio of 30:45:40:42:35:26:32. On the belt 310, the first conveyor belt 310 transports the raw materials supplied by the seven quantitative feeders 200 to the mixer 400 (LNX planetary roller mixer, Nanjing Xinghuo Machine Tool Co., Ltd.). Wherein, the total weight of each raw material supplied by the seven quantitative feeders 200 is shown in Table 1. Finally, the 7 kinds of raw materials and 120 kg of binder are stirred evenly by using a mixer 400 .

Embodiment 2

[0082] The batching was carried out according to the pellet raw material formula shown in Table 1, wherein the auxiliary raw material No. 3 was a high-ash raw material, and the rest were low-ash raw materials. Six kinds of low-ash raw materials, i.e. concentrated ore 1, concentrate 2, raw ore powder 1, raw ore powder 2, auxiliary raw material 1 and auxiliary raw material 2, are added to the 6 feed bins 100 respectively. Then utilize 6 quantitative feeders 200 to supply the above-mentioned 6 kinds of raw materials on the first conveyor belt 310 according to the weight ratio of 30:45:40:42:35:26, and the first conveyor belt 310 feeds the 6 quantitative feeders The raw materials supplied by 200 are delivered to the first buffer bin 510. Wherein, the total weight of each raw material supplied by the six quantitative feeders 200 is shown in Table 1.

[0083] Add 320kg of auxiliary raw material three (high ash raw material) into the second buffer bin 520 . Utilize the second conve...

Abstract

The invention discloses a pellet batching device and a pellet batching method. The pellet batching device comprises: a plurality of bunkers; a plurality of fixed quantity feeders which are respectively and correspondingly disposed under the bunkers so as to receive and supply a plurality of raw materials from the bunkers; a first conveyer belt which is disposed under and connected with the fixed quantity feeders so as to receive and convey a plurality of raw materials supplied by the fixed quantity feeders, wherein the fixed quantity feeders are distributed along the length direction of the first conveyer belt; and a mixer which is connected with the first conveyer belt so as to receive a plurality of raw materials conveyed by the first conveyer belt and uniformly mix the raw materials with auxiliary materials. The pellet batching device provided by the invention can be used to greatly shorten the mixing and stirring time and raise the batching efficiency.

Description

technical field [0001] The invention relates to the field of metallurgy, in particular to a pellet batching device and a pellet batching method. Background technique [0002] Pellet is a kind of artificial lump ore, which belongs to the concentrate of alloy production and smelting. The production process of pellets includes batching, molding machine pressure balls and drying treatment. During the batching process, various raw materials must be fully mixed. Due to the small particle size and variety of raw materials for pellets, and the large differences in chemical and physical properties, the batching process is very complicated. [0003] All are to utilize weighing scale or manually to finish batching work at present. Specifically, various raw materials of a certain quality are first weighed according to the formula, and then the various raw materials are sequentially transported to the mixing and stirring equipment, and finally the mixing and stirring equipment mixes t...
