What equipment is used for crushing dolomite?

Dolomite is a kind of medium and low hardness brittle ore. Its processing mainly includes three steps: primary crushing, secondary & fine crushing, and sand shaping. Based on the features of dolomite, Shibang Group supplies a full line of high-efficiency crushing machines from coarse crushing to sand making, to meet different output and particle shape needs.

1. Primary Crushing Equipment: C6X Series Jaw Crusher

It is the first crushing machine for dolomite processing. The C6X jaw crusher features large production capacity and stable performance. With heavy-duty design and deep crushing cavity, it can take raw dolomite stones up to 900 mm in size, with an hourly output of 50 to 1,200 tons. It works well for big raw dolomite rocks.By improving the moving jaw movement track, this machine has a large crushing ratio and low power consumption. Its wearing parts last much longer, making it the key primary crushing machine for dolomite production lines.

2. Secondary & Fine Crushing Equipment

PF / PFW Series Impact Crusher

Impact crushers are the cost-effective choice for soft and medium hard rocks like dolomite.The PF series has an hourly capacity of 50 to 260 tons, with a max feeding size of 350 mm. The PFW series can reach 70 to 400 tons per hour, and handle materials up to 700 mm.It crushes stones by impact force. Final products are cube-shaped with few flat or thin pieces, which meets high-quality aggregate standards. It comes with hydraulic adjustment and overload protection. The discharge size is easy to control, and daily maintenance is simple, perfect for medium crushing, fine crushing and stone shaping of dolomite.

HPT / HST Series Cone Crusher

If you need better stability and finer finished materials, cone crushers are the better option.HPT multi-cylinder and HST single-cylinder hydraulic cone crushers adopt the laminated crushing method. Their hourly output ranges from 45 to 1,400 tons. They produce more fine materials with good grain shape.These machines are highly automatic. The discharge opening can be adjusted quickly through the hydraulic system, ideal for large-scale and fine crushing of dolomite.

3. Sand Shaping & Making Equipment: VSI6X Series Sand Making Machine

To make high-quality manufactured sand of 0-5 mm from dolomite, the VSI6X sand making machine is the best choice.It supports two working modes: rock-on-rock and rock-on-iron. Its hourly output is 100 to 583 tons, with a feeding size below 50 mm.With upgraded crushing cavity and thin oil lubrication system, the service life of wearing parts is increased by 30% to 200%. The finished sand has reasonable grading and adjustable fineness modulus, which is ideal for dolomite sand making and aggregate shaping.

4. Flexible Production Line Solutions

We can provide mature matching solutions according to actual dolomite processing demands, such as jaw crusher + impact crusher for budget projects, and jaw crusher + cone crusher for high-quality materials. Combined with feeders, screening machines and dust removal equipment, a complete production line can be built.

For example, a dolomite project in Luoyang, Henan uses PFW European jaw crusher, HST cone crusher and VSI6X sand making machine. The total hourly output is 250 tons, and the finished products are used for highway construction.
