摘 要
本设计是霍州白辛二矿(白龙矿和辛置矿)3.00Mt/a矿区型选煤厂的初步设计。选煤厂工作制度为每年生产
330天,每天16小时,两班生产,一班检修。
本设计先对煤质资料进行分析、校正、计算,确定原煤是否分组、分级入选,分析原煤的可选性。在此基础
上,通过几个可能的选煤工艺流程,对其进行产品预测和技术、经济比较,选出最佳方案:不分级无压入料
三产品重介质旋流器分选流程,煤泥采用浓缩浮选。
方案确定后,进行介质、数质量流程计算。依据计算结果,进行设备选型。设备选型时,优先采用技术先进
、性能可靠、效率高、能耗低、成熟可靠的设备。在工艺布置时,做到生产流程通畅,设备布置紧凑,并便
于安装、操作和检修。在总平面布置上,对辅助生产设施进行了规划,兼顾了环保的要求。
除工艺流程外,本设计还对选煤厂的建筑结构、供电和电气、机修车间、铁路运输、劳动定员、生产成本及
建厂初步投资概算做了系统的设计。
产品指标如下:
精煤:产率,49.38% 灰分,8.94% 水分 11.36%
中煤:产率,17.60% 灰分,31.55% 水分 9.35%
矸石:产率,25.31% 灰分,78.55% 水分 15.00%

ABSTRACT
This design is about Longxin No.2 mining,Huozhou, coal preparation plant with a capacity of
3.0Mt/a .The time of real production is 330 days one year, sixteen hours one day ;both teams
produce, one team repairs in a day .
We analysis、emend and account the data of coal data at first. Then discuss the raw coal
whether is grouped and graded and analysis the beneficiability of coal. On these occasions we
do product forecast on several process flow. Finally vote the preferred plan during these
process flows by comparing these economy and technology. The result of the process flow is no
sizing dense medium separation of wide range and floatation.
After scheme determined, we did the the count of process and manufacturing facilities
selection. The manufacturing facilities selection’s governing principle is that using the
advanced techniques dependable performance efficient and less energy consumption equipment. So
we can make the workshop laid out compacted and it will be convenient to install、operate and
overhaul. During the square arrangement, we make a comprehensive programme to the subsidiary
manufacture facilities.It fulfils the environmental protection requirement.
Besides the technological process, the project also include projects systematically about the
supplying of the electricity, the machine repairing, the railway transportation, the number of
worker, the budgetary estimate in economy, the budgetary estimate of the primary invest of
building of the plan and room.
The products are as follow:
Cleaned coal:Wt,49.38% Ad,8.94% Mt,11.36%
Steam coal: Wt,17.60% Ad,31.55% Mt,9.35%
Refuse: Wt,25.31% Ad,78.55% Mt,15.00%
Keywords:coal preparation plant ; design; dense medium separation of wide range; direct
floatation
