A pebble is a clast of rock with a particle size of 4 to 64 millimetres based on the Krumbein phi scale of sedimentology. Pebbles are generally considered to be larger than granules (2 to 4 millimetres diameter) and smaller than cobbles (64 to 256 millimetres 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.
Pebble Crushing Process:
Big stone will be fed into jaw crusher for primary crushing by vibrating feeder. After primary crushing, the material will be transferred to secondary crushing machine like cone crusher for further crushing. Usually, we will equip the pebble crushing & screening plant with multi-deck vibrating screen. The vibrating screen is a key equipment to sieve the crushed stones into different grades. The crushed stone that meet the demands will be transported to the stockpile, the other will be sent to cone crusher for fineness crushing.
Pebble crusher is always used with SAG mills in metal ore crushing and processing in a recirculation circuit. Usually, cone crusher, impact crusher play the role as pebble crusher in gold ore crushing, copper ore crushing, iron ore crushing and so on.
Pebble crusher is also widely used in all kinds stone crushing plant, it is an ideal crushing equipment for crushing river stone, sandstone, river gravel, cobble stone, pebble, cobble ,granite,basalt and so on crusher is a special equipment processing construction sand and stone. Pebble aggregate with uniform size and high compressive strength is more ideal than the natural sand, manufactured sand hammer breaking high standards more in line with requirements of construction sand. It is a complete line based on feeder, jaw crusher, sand making new, heavy-duty shaker and efficient washing Sand.
