Percobaan Kinerja Alat Peremuk dengan Mengatasi Kelebihan Beban Pada Jaw Crusher 3 dan Mengatur Ukuran Lubang Screen pada Vibrating Screen 2 di PT Bailey Rekatama Desa Mekarsari, Kecamatan Cikalong Kulon, Kabupaten Cianjur, Provinsi Jawa Barat

Abstract

Abstract. PT. Bailey Rekatama is a company engaged in andesite stone mining since 2006, PT Bailey Rekatama opened its first mining location located in Cimuncang Block, Mekarsari Village, Cikalogkulon District, Cianjur Regency, West Java Province. As development in Indonesia is very rapidly increasing, so that the standard needs are very in need, especially andesite rocks, so that PT Bailey Rekatama opens the second mining location in the Mekarsari block Mekarsari Village, Cikalogkulon District, Cianjur Regency, West Java Province, to meet the very high consumer needs . PT. Bailey Rekatama has several tools, namely SHANBAO SBM PE600 × 900 Jaw Crusher 1 piece, SHANBAO SBM PE250 × 1000 Jaw Crusher 2 pieces SHANBAO SBM PE250 × 1000 1 piece Jaw Crusher, as well as Impact Crusher PF-1210 1 piece. In the production trial at PT Bailey Rekatama a belt cut test was carried out to determine the production data, the overload in unit 3 jaw crusher was 1.43 tons / hour so the trial production process was not continuous, in overcoming the problem in unit 3 jaw crusher, an alternation experiment was carried out. screen size of 3 cm to 3.5 cm, so that the grain size data is more than 3.5 cm by 32% and less than 3.5 cm by 68%. Calculation of the amount of feed material that enters using data screen size of more than 3.5 cm by 32% in the production of 11.11 tons / hour so that there will be no overload because it does not exceed the production capability of 3 crusher jaw 14.89 tons / hour . From the results of this crushing unit, the production of sand products is 11.96 split1-2 39.89 tons / hour Screening 0.5-1 29.98 tons / hour Stone ash 22.49 tons / hour so the total production is 104.32 tons / hour 634.26 tons / day 19,027 tons / month

Abstrak. PT. Bailey Rekatama merupakan perusahaa yang bergerak di bidang pertambangan batu andesit sejak tahun 2006, PT Bailey Rekatama membuka lokasi penambangan yang pertama yang berlokasi di Blok Cimuncang Desa Mekarsari Kecamatan Cikalogkulon Kabupaten Cianjur Provinsi Jawa Barat. Seiring pembangunan di indonesia yang sangat meningkat pesat, sehingga kebutuhan baku pun sangat di butuhan terutama batuan andesit, sehingga PT Bailey Rekatama membuka lokasi penambangan yang ke dua di blok Mekarsari Desa Mekarsari Kecamatan Cikalogkulon Kabupaten Cianjur Provinsi Jawa Barat, untuk memenuhi kebutuhan konsumen yang sangat tinggi. PT. Bailey Rekatama  memiliki beberapa alat yaitu Jaw Crusher SHANBAO SBM PE600×900 1 buah, Jaw Crusher SHANBAO SBM PE250×1000 2 buah Jaw Crusher SHANBAO SBM PE250×1000 1 buah,  serta  Impact Crusher PF-1210 1 buah. Dalam percobaan produksi di PT Bailey Rekatama dilakukan uji belt cut untuk mengetahui data peroduksi, kelebihan beban di jaw crusher unit 3 sebesar 1,43 ton/jam sehigga proses percobaan produksi tidak kontinyu,dalam mengatasi permasaahan di jaw crusher unit 3 maka dilakukanlah percobaan dengan pergantian ukuran screen 3 cm menjadi 3,5 cm, sehingga di mendapat data ukuran butir lebih dari 3,5 cm sebesar 32% dan yang kurang dari 3,5 cm sebesar 68%. Perhitungan jumlah material umpan yang masuk menggunakan data ukuran screen lebih dari 3,5 cm sebesar 32% di hasil produksi sebesar 11,11 ton/jam sehingga tidak akan terjadi kelebihan beban karna tidak melebihi kemampuan produksi jaw crusher 3 sebesar 14,89 ton/jam. Dari hasil unit peremukan ini menghasilkan produksi produk pasir 11,96 split1-2 39,89 ton/jam Screenin 0,5-1 29,98 ton/jam Abu batu 22,49 ton/jam jadi total produksi 104,32 ton/jam 634,26 ton/hari 19.027 ton/bulan
