| Equipment suitable for crushing large lumps as they | | | | friendly, low consumption stone crusher to meet the |

| pulverize to fine powder, so the operation is carried on | | | | For example: Initial developed large scale single stage |
| in three or more stages called primary crushing, | | | | hammer crusher can crush maximum 1 cubic meter |
| secondary crushing, and pulverizing. The three stages | | | | crude ore to proper particle only off and its production |
| are characterized by the size of the feed material, the | | | | capacity is 300-800TPH, which simplify the multi stage |
| size of the output product, and the resulting reduction | | | | or two stage crushing to one stage(primary crushing). |
| ratio of the material. The crushing-stage output may be | | | | Soon after, Tianjin cement industry research institute |
| screened for greater uniformity of product size. | | | | developed high production capacity single stage |
| The reduction of materials such as stone, coal, or slag | | | | hammer crusher of 1200TPH to apply a cement |
| to a suitable size for their intended uses such as road | | | | company, that get a measured results: |
| building, concrete aggregate, or furnace firing. | | | | Stable capacity is 1200TPH |
| Reduction in size is accomplished by five principal | | | | The percent of finished product size of 40mm is |
| methods: (1) crushing, a slow application of a large | | | | 94.59% |
| force; (2) impact, a rapid hard blow as by a hammer; | | | | The main motor electricity consumption is 0.415Kwh/t. |
| (3) attrition, a rubbing or abrasion; (4) sudden release of | | | | Later,Tianjin institute cooperate with Hefei institute to |
| internal pressure; and (5) ultrasonic forces. The last | | | | develped the highest capacity single stage hammer |

| In open-circuit pulverizing, the material passes through | | | | maximum feeding size is 1.8*1.2*1.2m, per crusher |
