3 Breaker classifications and use scope

The breaker use scope as a result of the category difference and the difference, may pide into sketchily according to the breaker function way the breaker two big kinds, the breaker and the ore mill.

The breaker general processing bulk material, the product granularity is thick, usually is bigger than 8 . Its structure characteristic is between stave has certain gap, contacts not mutually. The breaker may pide into the bulldozer, the intermediate crusher and the small aggregate crusher. Generally speaking the ore mill processes the material is thin, the product granularity is the fine grain, may amount to 0.074 , even also wants thin. Its structure characteristic is the stave part (or medium) contacts mutually, uses the medium is the steel ball, the steel rod, the broken stone or the ore block and so on. But some machineries are simultaneously have at the same time the garrulous ore and the rubbing function, like autogenously tumbling mill. The rice autogenously tumbling mill processing ore granularity upper limit may amount to 350~400 , product degree of fineness reaches 100~200 goals to account for about 40%.

The stave machinery which according to the stave way,the machinery structure characteristic (movement principle) pides into six kinds on the whole.

(1) Huber type breaker (old tiger’s mouth)

The stave function is depends on the movable Huber board periodic geostatic pressure to fix the Huber board, will clamp in the among ore block squash.

(2) Circular cone breaker

The ore block is in between inside and outside two circular cones, the external cone is fixed, the internal cone makes biased swinging, will clamp in the among ore block squash or breaks off.

(3) Roller type breaker

The ore block in two opposite direction revolving round roller crevice, mainly receives the continual squash function, but also has the abrasion function, the serrated roller surface also has chops into pieces the function.

(4) Impact type breaker

The ore block receives the fast rotation the movement part impact function to crush. Belongs to this kind to be possible to pide into:Hammer crusher; Cage type breaker; Counter-attack type breaker.

(5) Ore mill

Ore receives the rubbing medium in the revolving cylinder (steel ball, steel rod, broken stone or ore block) the impact and the abrasive action are crushed.

(6) Other type stave ore mill

A  Roller grinding machine: Grind taking advantage of the rotation Rolla rounds the material.

B Disk grinder: Takes the stave part using the vertical axis or the horizontal axis disc rotation.  

C Centrifugal mill: Uses the high speed revolving part and the medium produces the production centrifugal force to complete the stave function.  

D Vibrates the ore mill: Has the high-frequency vibration using the revolution axis, causes the medium and the material strikes against mutually completes the stave function.

Each kind of breaker has the different specification, different use scope. At present, chooses the factory thick garrulous multipurpose Huber type breaker or the cycle circular cone breaker; Uses the standard circular cone breaker garrulously; Uses the short head circular cone breaker in broken bits; The rough grinding with the rod mill, the fine grinding uses the ball mill.

4 Bauble roll breaker concrete introduction

The double roll breaker is suitable for in the cement, the chemical industry, the electric power, the metallurgy, the building materials, industry sector stave medium degree of hardness and so on fire-proof material materials, like limestone, slag, coke, material and so on coal garrulous, work in broken bits.

This series mainly is composed, roller turn parts and so on support bearing, compaction and adjusting device as well as drive to the double roll breaker by the roller wheel composes.
