Abstract
The invention proposes a lignite or peat smashing method; and a combination of a chain type crusher and a wheel type crusher serves as main equipment to enable the probability of continuously and stably smashed lignite or peat, with high water content, passing through a 20-mesh screen to reach 90%. The method comprises the following steps: lignite or peat raw materials are smashed to enter the combination of the chain type crusher and the wheel type crusher by a conveying device for crushing.
Description
Technical field
The present invention relates to a kind of breaking method, particularly relate to and a kind ofly utilize the combination of chain breaker and wheeled type crusher to the breaking method of brown coal or peat.
Background technology
The degree of coalification of brown coal is lower, and its reserves are comparatively large, account for 40% of world's coal gross reserves, verifies coal possess in resource reserve and account for 13% in China.Brown coal moisture is high, Eastern Inner Mongolia brown coal total moisture is up to about 30.50%, young brown coal (No. 2, the brown coal) moisture content of Indonesia is up to 62%, and the feature of High water cut brings difficulty to the pulverizing of brown coal, limits the further processing and utilization of brown coal.
Peat is organic mineral resources that plant residue dead in marsh transforms accumulation formation.The organic matter of peat and fiber content enrich, and loose porous, ventilating permeable is good, is good arable farming matrix.Containing large quantity of moisture in peat, general water content is 70% ~ 90%, and the moisture content of Indonesia's woody peat reaches 55%-62%, and the water content of Chinese meadow peat is generally 60% ~ 80%, and bog moss is then greater than 90%.The feature of High water cut, fibre-enrich brings difficulty to the pulverizing of peat, limits the value of carrying out further product development utilization using peat as raw material.
To the pulverizing of moisture high brown coal or peat, traditional method carries out drying and dehydrating to material before pulverizing, it can be the successional industrialization drying device of investment construction, also can be utilize natural climate airing, use the drying of which kind of method all to further processing the increase bringing investment and cost, if need moisture content again in especially follow-up processing technology, first drying brings serious impact will to the design of technique and the cost of product.
Summary of the invention
The present invention is directed to the pulverizing problem of moisture high brown coal or peat, be combined as capital equipment with chain breaker and wheeled type crusher, moisture high brown coal or peat can be made continuously, stably to realize crushing rear material and reach 90% by the probability of 20 eye mesh screens.
The invention provides the breaking method of a kind of brown coal or peat, brown coal or peat raw material after fragmentation, then are pulverized through the combination that conveying device enters chain breaker and wheeled type crusher.
Optionally, described brown coal or peat raw material are any one or two kinds of combinations of brown coal or peat, and water content is 10%--65%.
Optionally, the combination of described chain breaker and wheeled type crusher is the combination of a chain breaker and one or more wheeled type crusher, or the combination of one or more chain breaker and a wheeled type crusher; Can be vertical layout between chain breaker and wheeled type crusher, successively by chain breaker and wheeled type crusher; Also can be horizontally disposed, successively by chain breaker and wheeled type crusher.
Optionally, described in be broken for the zero broken one-level that adds broken or zero brokenly add one-level fragmentation and add two-stage crushing, make granularity reach 5mm--3mm.
Optionally, the material carrying out pulverizing through the combination of chain breaker and wheeled type crusher reaches 90% by the probability of 20 eye mesh screens.
Technical scheme of the present invention is as follows: moisture lower than 65% brown coal or peat raw material is broken through zero passage, one-level is broken reaches below 150mm, then enter two-stage crushing granularity through conveying device and reach 5mm--3mm, enter the combination of chain breaker and wheeled type crusher again through conveying device, realize crushing rear material and reach 90% by the probability of 20 eye mesh screens.
Wherein, the combination of chain breaker and wheeled type crusher can be the combination of a chain breaker and one or more wheeled type crusher, also can be the combination of one or more chain breaker and a wheeled type crusher, can be vertical layout between chain breaker and wheeled type crusher, material leans on gravity successively by chain breaker and wheeled type crusher; Also can be horizontally disposed, rely on conveying device successively by chain breaker and wheeled type crusher.
Raw material described in technique scheme is any one in brown coal or peat or two kinds of combinations, and water content is 10%--65%.
Method provided by the invention is compared with published method, and tool has the following advantages:
1. energy consumption is low
Moisture high brown coal or peat are directly pulverized, avoid brown coal or peat raw material in process first drying and dehydrating, then just can pulverize the technique of processing, especially material is needed to contain the subsequent product processing of certain moisture, not only reduce the energy consumption in process, also greatly reduce investment and production cost simultaneously.
2. airborne dust is few
Because moisture high brown coal or peat are directly pulverized, not through super-dry, moisture content is high, so airborne dust is few in crushing process, effectively reduces the environmental pollution in process, avoids loss of material simultaneously.
Detailed description of the invention
Below one exemplary embodiment of the present invention is explained, comprising the various details of the embodiment of the present invention to help understanding, they should be thought it is only exemplary.Therefore, those of ordinary skill in the art will be appreciated that, can make various change and amendment, and can not deviate from scope and spirit of the present invention to the embodiments described herein.Equally, for clarity and conciseness, the description to known function and structure is eliminated in following description.
Embodiment 1: Indonesia's woody peat raw material of moisture 62% is broken through zero passage, one-level is broken reaches below 150mm, then enter two-stage crushing through conveyer belt and reach below 5mm, enter the transverse horizontal combination of 2 chain breakers and 1 wheeled type crusher again through conveyer belt, realize crushing rear material and reach 91% by the probability of 20 eye mesh screens.
Embodiment 2: the Huolinhe lignite raw material of moisture 28% is broken through zero passage, one-level is broken reaches below 150mm, then enter two-stage crushing through conveyer belt and reach below 3mm, enter the transverse horizontal combination of 1 chain breaker and 2 wheeled type crushers again through conveyer belt, realize crushing rear material and reach 95% by the probability of 20 eye mesh screens.
Embodiment 3: the Yunnan meadow peat raw material of moisture 52% is broken through zero passage, one-level is broken reaches below 150mm, then enter two-stage crushing through conveyer belt and reach below 3mm, enter the vertical combination of 1 chain breaker and 1 wheeled type crusher again through conveyer belt, realize crushing rear material and reach 92% by the probability of 20 eye mesh screens.
Above-mentioned detailed description of the invention, does not form limiting the scope of the invention.It is to be understood that depend on designing requirement and other factors, various amendment, combination, sub-portfolio can be there is and substitute in those skilled in the art.Any amendment done within the spirit and principles in the present invention, equivalent replacement and improvement etc., all should be included within scope.
