The proven and reliable Dsmac DPC series Hammer crusher is a cost-effective solution for processing abrasive and moderately sticky raw materials in one stage. it mainly suitable for crushing various ores the compressive strength of which is no more than 150MPa.
Hammer crushers for a wide range of capacities can be found in the cement industry where ball mills are part of the grinding plants, in desulphurization lines and lines producing plaster mixtures.
Another feature that reduces downtime and makes servicing of the crusher safer is the hydraulic opening of the crusher housing. Installing two hydraulic cylinders, appertaining brackets and a set of hinges enables the crusher to be opened within 5 - 10 minutes.
Hydraulic tool for changing of hammers
A hollow hydraulic cylinder placed in a rigid frame is provided to handle the hammer bolts when turning or changing hammers. A mobile hydraulic power unit supplies the hydraulic pressure to operate the cylinder.
The outlet grate assembly is equipped with sturdy, replaceable grate bars supported by heavy cheeks. The position of the outlet grate assembly can be adjusted in order to control the crushed product. This takes place hydraulically from outside the crusher casing
Method of operation
1) The first stage is effected by percussion and impact as the material is gravity-fed into the tip circle of the hammers.
2) The material then passes onto the anvil located centrally between the rotors, where it is crushed further by percussion and shear forces.
3) The material flow is spread over the following discharge grates, where the product granulometry is separated and discharged through the grates. Any remaining material continues to be processed until it, too, can pass through the grate gap. The grate bar gap spacing determines the end product size.
