Hammer Crusher is used for primary crushing of brittle rocks neobrazivnyh, medium and mild strength. Natural moisture content of rocks shall not exceed 10%. These rocks are chalk, gypsum, asbestos ore coal, limestone, brick fight, marl, clay, etc. For the secondary crusher hammer crusher is also used, the size of crushed material in this case – 100-200 mm to 20 mm and smaller. Divide sticky or viscous materials humidity above 15% of the hammer mill can not. For materials that are capable of clogging are designed with a mobile crusher hammer plate.
Grinding the material in hammer mill is due to strike rapidly rotating hammers to pieces of material, hit pieces against each other and on the boards, which then dropped material.Preimuschestva hammer crushers Low unit costs – the main advantage of hammer crushers. In comparison with the fragmentation method of crushing, crushing blow to the hammer crusher, grinding gives the best effect. The advantages of hammer crushers are: reliability, low weight, high performance, simplicity and compact design, continuous operation. Distinguish hammer mills hammer on the location, method of attachment, the number of rotors, according to the type and position of the discharge device in the form of crushing plates in the direction of rotation of the rotors. The rotors can be operated in reverse and irreversible rezhime.Reversivnye crusher: the principle of reversing mills have been developed for better use of technical knowledge about crushing blows. This is a major advantage, which ensures minimum wear, maximum productivity and product quality.
Crushing of the material reverse crusher made using punches. Reversible crusher – a machine that produces the ideal products for the production of asphalt and concrete conglomerate and guarantees a constant grading curve. Reversing mill is equipped with separate hydraulic control for the defense, special vibratory feeder and a constant power supply. The crusher is ideally suited for crushing materials with a small guaranteed high yield and low sand filler formulation. The internal protective linings made so that it could easily be replaced in case of a single rotor hammer mill iznosa.Ustroystvo Single- hammer mills – the most numerous type of hammer crushers. Shaft hammer crushers single rotor begins to rotate through the coupling of the electric motor, which is put on the bearings. Rotor discs assembled on shaft, and the wheels are suspended hammers. At the bottom of a single rotor crusher is grate. It consists of front and rear ends, each of which apparently is a set of grates tapered section, which are enshrined in the two rods. Housing crusher consists of two parts that are fastened together with bolts. Feed opening for the material at the top of the housing. Its walls otfuterovany plates that protect against abrasion. Plates are also involved in crushing. The material that enters the crushing chamber, is subjected to rapidly alternating hammer blow of the rotor is rotating. Material is shredded and passed through the hole grates, and then goes to the assembly line or in the bunker.
