Read MoreBetter yet is to use a desktop mill for initial evaluation. If any fine particles are produced, there is a good chance the material will mill. However, the best method for determining if hammer milling is the right choice for particle size reduction is to run a small-scale test on production hammer mills.
Read MoreHammer mills such as the BTM series (Bohle Turbo Mill) by L.B. Bohle can reach speeds of 600–6000 rpm and produce up to 1500 kg/h. To achieve this, the BTM is equipped with an automatic dispenser unit (rotary feeder).
Read MoreDifferent grinding methods, including the use of roller mills, hammer mills, multicracker and multi-stage grinding were reviewed. Roller milling tends to produce a more uniform particle size distribution (PSD) and consumes less energy, whilst hammer mills have a greater grinding capacity and a higher reduction ratio compared to roller mill.
Read Moremills have intrinsic cooling due to compressed air expan-sion in the body of the mill. With the help of sweeping air, hammer mills may also be able to process materials with low melting points for coarse grinding applications. Explosibility. The risk of dust explosions must be taken into account when a material is ground very fine in a milling
