Technical Data

A pebble is a clast of rock with a particle size of 4 to 64 equipmentimetres based on the Krumbein phi scale of sedimentology. Pebbles are generally considered to be larger than granules (2 to 4 equipmentimetres diameter) and smaller than cobbles (64 to 256 equipmentimetres diameter). A rock made predominantly of pebbles is termed a conglomerate. Pebble tools are among the earliest known man-made artifacts, dating from the Palaeolithic period of human history. Cobblestones are stones that were frequently used in the pavement of early streets.

Cobblestones are typically either set in sand or similar material, or are bound together with mortar. Paving with cobblestones allows a road to be heavily used all year long. It prevents the buildup of ruts often found in dirt roads. It has the additional beneficial advantage of not getting muddy in wet weather or dusty in dry weather. A disadvantage is that carriage wheels, horse hooves and even modern automobiles make a lot of noise when rolling over cobblestone paving. In England, the custom was to strew the cobbles outside the house of a sick or dying person with straw, so as to dampen the sound.

Shanghai Clirik Machinery Co., Ltd. is a manufacturer of HGM series grinding equipment, rock grinding equipment, stone grinding equipments, milling machinery, ultrafine powder equipment, and powder ultra fine equipment.

Product fineness can be controlled between 325~2500 mesh.

Features of micro powder grinding mill

  • High efficiency

Under the same finished final size and the same motor power, the capacity of micro powder grinding mill is twice as much as jet mill, mixing grinder and ball mill.

  • Long lifecycle of spare parts

The ring and roller are forged by special material with high utilization. Under the same grinding material and finish special size, the lifecycle of spare parts is about one year, which is 2-3times longer than impact mill or turbo mill. Furthermore, the lifetime can reach 2-5 years for grinding calcite carbonate.

  • High safety and reliability

As no rolling bearings or screws in grinding cavity, there are no problems caused by bolts shedding or rapid wear of bearings and seal components.

  • High fineness and flexible adjustment

The final fineness of the grinding materials can be adjusted between 325 meshes and 3000 meshes, and the product fineness can reach D97≦5um.

  • Environment-friendly

The application of pulse deduster and muffler greatly alleviates dust pollution and noise.
