3.Technical data The MBM-100 is a laboratory machine and is suitable for milling and homogenizing soft, fibrous, hard and brittle materials in the wet and dry state. The MBM-100 have two grinding platform, grinding jars which have different materials and volume can be used. For fast, super fine milling of two samples simultaneously. The closed milling system guarantees complete recovery of the samples. Owing to the extremely short milling time and the high final fineness of the material to be milled The MBM-100 is also ideally suitable for sample preparation for all spectral analyses. Final finenesses of down to 10 µm can be achieved, depending on the milling time and the specific properties of the sample material. The optimum grinding jars filling is as a rule :1/3 of the grinding jar volume. If used the adapter, it can grinding 20~196 samples at the same time(it depends on the kinds of the adapter) Due to grinding with very short time and superfine grinding fineness, MBM-100 is the ideal choice for grinding the all sample preparation and analysis. Finally the sample size up to 10 um, this depending on the milling time and the nature of the sample material properties. Do not make any alterations to the machine and use only spare parts and accessories approved by MRC This will damage to equipment Furthermore, this will also lead to the loss of any guarantee claims. 3.1Grinding jars Material Stainless steel:5, 10, 25, 35, 50ml Zirconium oxide:35ml Tungsten carbide:25ml 3.2 Filling quantity 1/3~1/2grinding jar capacity 6

I E F 6.5 Grinding operation 6.5.1 Clamp/Release jars Place the grinding jars, filled with the material to be grinding and the milling balls, into the centering points of the holder and clamp firmly., Pull the locking pin E upwards from the groove and turn through 90.This unlocks the locking device. Turn the hand wheel F counterclockwise until the Max. clamping range is reached. Insert grinding jars I and press lightly into the centering point. Turn the hand wheel F clockwise until the grinding jars just fits, free of play in the holder. Then continue to turn the hand wheel F until the grinding jars is tightened.(but not too tight). Turn the locking pin E back through 90 until it engages in the groove again. Turn the hand wheel F clockwise lightly until the lock pin E is in the lower position. The engaged locking pin reliably prevents automatic opening of the grinding jar holder. If the locking pin E cannot be pulled upwards to release it, unlocking should not be forced with a hammer or similar tool. Otherwise the hardened locking pin can break off. Briefly turn the hand wheel F in the clockwise direction the locking pin E can then move freely again. To remove the grinding jar lift the locking pin and 13
turn the hand wheel in the opposite direction. In order to guarantee quiet running of the MBM-100 both milling positions must be loaded with approximately the same mass Ensure that the grinding jars are inserted correctly in the guides. Otherwise the grinding jars will be damaged when the machine is started When removing and opening hot grinding jars, always wear protective gloves. Danger of burning the hands. 6.5.2 Setting time Use the time key 11,12 / to setting required times 00:~99min, 00~59sec 11 6.5.3 Setting speed Use the speed key 13,14 / to setting required speeds 200~2000RPM 6.5.4 Storing the grinding parameters 11 12 13 14 Storing or calling the preselected grinding parameters can be carried out only in the on mode.
