近日,桂箐煤矿为达到块煤与粉煤的有效筛分,保证公司产煤效率及产煤质量,进一步增加原煤经济效益,在桂箐煤矿机电工区广大职工的研究讨论下,对筛分楼振动筛进行改造。改造方案分为前期准备和安装两个阶段。新振动筛板采取分层筛选的方案,共需加工筛板两层。第1层筛板因考虑受到冲击较大及振动筛电机承受能力,选用δ=8 mm铁板;第2层筛板因考虑煤经过第1层筛板后冲击较小及振动筛电机承受能力,因此选用δ=4 mm铁板,并考虑运输安装方便,每层筛板分别加工成4块。最后,用吊车将筛板运至安装地点,由人工将筛板定位,使用电焊将筛板连接,并用螺栓将
Recently, Gui 箐 coal mines in order to achieve effective screening of lump coal and pulverized coal to ensure that the company coal production efficiency and quality of coal production, and further increase the economic benefits of raw coal, coal mine in Gui 广 coal mine workers and staff in the area of discussion, Shaker to transform. Transformation program is divided into two stages of pre-preparation and installation. New vibration sieve stratified screening program, a total of two sieve plate processing. The first layer of sieve plate due to consider the greater impact and vibrating screen motor capacity, the choice of δ = 8mm iron plate; the second layer of sieve because of the coal through the first layer of sieve after the impact of smaller and shaker motor capacity , So the choice of δ = 4 mm iron plate, and consider the transport and easy installation, each layer sieve were processed into four. Finally, the deck is transported to the installation site by crane, the deck is manually positioned, the deck is welded by electric welding,
