What is rubble? What equipment is needed to process rubble into gravel?

February 14, 2022

The rough rubble generally requires that the thickness of the middle of the stone is not less than 150mm, the length is 300-400mm, the mass is about 20-30kg, the strength should not be less than 10MPa, and the softening coefficient should not be less than 0.8; the flat rubble is slightly processed from the rubble. , the shape is more chaotic and tidy, its shape basically has six sides, but the surface is rough, and the thickness of the middle is not less than 200mm.

1. How many tons of gravel can be processed in one ton of rubble?

The rubble will go through multiple steps such as primary crushing, secondary crushing, medium and fine crushing, and screening, and eventually become crushed stones of different sizes. 05, 12, and 13 stones are common crushed stone specifications.

The general yield of rubble processed into crushed stone is about 80-90%, that is to say, one ton of rubble can break more than 0.8-0.9 tons of stones.

Of course, how much gravel can be crushed in one meal still needs to be combined with the actual situation such as the cleanliness of raw materials, the requirement of discharging particle size, and the shape of the crushing equipment. decline.

2. What equipment is needed to process rubble into gravel?

1). Jaw crusher (coarse crushing equipment)

Production capacity: 1-1000t/h,

Feed size: ≤1200mm
