Embodiment Construction

[0022] A method for forming lignite particles, the concrete steps are as follows:

[0023] a, screening: soil lignite is separated from lump coal and lump coal gangue to obtain lignite raw material;

[0024] b, crushing: using a lignite crusher to crush the lignite raw material in step a to obtain lignite powder;

[0025] C, molding: utilize lignite molding machine to make the lignite powder that b step makes particle diameter be 4-10mm, the length is the lignite particle of 4-10mm;

[0026] d. Cooling and dehumidification: dry the lignite particles obtained in step c at 50-60° C. for 2-5 hours, and then ventilate and dry for 10-12 hours to obtain the finished product.

[0027] The brown coal crusher is composed of a housing 1, a rotor and a knocking plate, the housing 1 is a hollow structure with a lower opening, and the top of the housing 1 is provided with a feed port 3, and the feed port 3 A material guide plate 11 is provided below the bottom of the ram, so that the lig...

Abstract

The invention relates to a lignite particle formation method. The lignite particle formation method comprises four operation steps of screening, smashing, formation and cooling dehumidification. Lignite particles are prepared by a lignite smashing machine and a lignite granulation machine, and the stability of a finished product is also improved as well as the granulation efficiency is improved bycombining a unique design of easier entrance and stricter exit of a press hole and a perpendicular synchronous rotation design of a scrapper outside a press die and an internal press barrel from an angle of a ring die rapid-disassembly principle; meanwhile, the granularity of the finished product is uniform, the smashing path of original material lignite is expanded to a great extent by a hammerdesign and a wavelike plate design, and a smashing effect is better; and buffer devices are arranged at both of a front striking plate and a rear striking plate, the service lifetime of the front striking plate and the rear striking plate is prolonged, and the maintenance cost is reduced.

Description

Technical field: [0001] The invention relates to the technical field of coal powder molding, in particular to a lignite particle molding device and method. Background technique: [0002] At present, lignite is a kind of earthy coal. During the combustion of lignite, the coal body has poor fluidity, high water content, and low thermal efficiency. Therefore, it needs to be granulated to achieve the purpose of removing moisture and improving fluidity and thermal efficiency. . During the granulation process, the raw lignite needs to be crushed first, so that the molding can be more compact and the granule strength is better. However, in the existing crushing equipment, the particle size of the finished product is uneven, and the crushing effect is not good. At the same time, due to the physical crushing method, the shock absorption effect of the parts is not good, and the maintenance cost is high. At the same time, the existing molding machine has poor granulation effect, low ...
