The process of making iron using a blast furnace is quite large and efficient. The main material needed in the blast furnace process is iron ore, both high content (lump ore) and processed products (pellets or sinter). The blast furnace height of ±20-30m can cause damage or damage to the iron ore in the form of lumps of ore, sinter, or pellets which will result in decreased efficiency due to the distribution of hot gas which is hampered by the destruction of raw materials which causes the permeability to decrease during the process. iron making. The process of testing the success of the equipment was carried out by conducting an experiment by weighing 20 kg of sintered samples, placing the sample into the sample box being lifted at a height of 2 meters and the sample being dropped (the experiment was carried out 4 times). Samples were weighed and a screening process was carried out using sizes of 10 mm and 5 mm, the results of the screening were weighed for each fraction +10 mm, −10+5 mm, and −5 mm. So it takes a break test of raw materials using a shatter test tool to be able to determine the shatter index of these raw materials. Therefore, the design and manufacture of this shatter test device aims to determine the shatter index of raw materials for making iron such as sinter, lump ore, or pellet. The shatter test equipment is made on a laboratory scale based on Indian Standard 9963-1981. The research began with designing a tool with the Skechup application, then tested with several samples of up to 20 kg. In order to withstand a load of sample about 20 kg, it requires This research produces a prototype shatter test equipment with the selection of canal steel and shielded metal arc welding (SMAW) welding types for the joints.
