Gardner crusher ( Hammer crusher )

Hammer crusher (hammer mill) is suitable for mid-hard and light erosive materials.

A swing and hammer crusher, the hammers being pieces hung from trunnions between two disks keyed to a shaft. When revolved, centrifugal force throws the hammers out against the feed and a heavy anvil inside the crusher housing.

Hammer crusher (hammer mill) is suitable for mid-hard and light erosive materials, whose pressure resistance strength is no more than 100Mpa and humidity lower than 15%, such as coal, salt, chalk, gypsum, blocks, limestone, etc. The PCA-Hammer crusher is suitable for  both dry and wet crushing of brittle, medium-hard materials for the mining,coal, metallurgic, construction material, road building, and chemical industries. the maximum, compressive resistance of the crushed materials can be up 150Mpa.

Hammer Mill Operating Principle:

The main working part of hammer crusher is rotors with hammer. The rotors consist of main shaft, disk, pin shaft and hammers. The motor drives the rotors to rotate quickly in the crushing cavity. Raw materials enter the crusher through the feed opening and are stricken, impacted, cut and ground by the high-speed hammer to small size. There is a screening plate under the rotor, so that materials with size smaller than the screen mesh will be screened out and others are left to be further hammered and ground until reach the standard size. The size of the final product can be adjusted by changing the screening plate. The gap between the rotors and the screening plate can also be adjusted according to different requirement.

Detailed Product Description:

Our hammer crusher series products are applicable for various hard and fragile materials, such as limestone, coal, salt, gypsum, alum, brick and tile, etc. the crushing compressive strength of materials should not be in excess of 150Mpa. The hammer crusher is mainly used in such industries as cement, coal separation, electricity generation, building materials and compound fertilizer, etc. The hammer crusher can crush materials with different sizes into equal particle, which favors the next procedure. The hammer crusher has the advantages of reliable mechanical structure, high productivity and favorable applicability.

The main features of hammer crusher:

1.It is of various types.

2.It is suitable for crushing maximum, medium and minimum stones.

3.It is easy to be operated.
