Concrete aggregate refers to those mineral particulate materials with diameter over 0.16mm which usually play the role of fill and skeleton in concrete. High-density concrete aggregate usually refers to heavy concrete and the barite stone must be firstly pulverized into 200mesh ~ 325mesh before being used to produce high-density concrete aggregate. You can choose SBM grinding mills to produce fine barite powder. SBM will offer you customized solution according to your requirement. To improve efficiency, the bag filter can be changed to pulse bag filter and the whole powder grinding system can be designed as open circuit instead of closed circuit.

Raw materials used in high-density concrete aggregate industry:
Materials: Barite
Fineness Requirement: 200mesh ~ 325mesh
Grinding plant: MTM Trapezium Grinding Mill, MTW European Grinding Mill

SBM barite grinding mills (1.6~0.045mm)
To crush barite stone to be 200mesh ~ 325mesh, you can choose our MTM Trapezium Grinding Mill and MTW European Trapezium Mill. By using SBM grinding mills, you can accurately control your desired fineness. After pulverized by SBM grinding mills, you can directly apply these barite powders in high-density concrete aggregate.

MTM Mill MTW Mill MTM Trapezium Mill is a world leading level industrial mill.It is designed by our engineers and technical workers ,basing on many years industrial mill design ,adopting world leading powder making teachnology.

High grinding efficiency Inverted trapezium roller and ring can reduce materials' slip velocity. Steady and low noise Press spring keeps the balance. Resilient connection ensures reduces noise. - High grain finesse Product powder precision is improved by 50% compared with Raymond mill.

MTW continencial trapezoid mill are designed by our experts, according to advices of customers' long-term experiences. They adopt bevel gear integral transmission, inner light-oil lubrication system, arc whirl tube and another proprietary technology.

Special transmission Bevel gear integral transmission compact structure and simplify installation. - Efficient lubrication Bearing lubrication realized without oil pump or lubrication station. - Long service time Curved surface edge of alloy material is more wearable and easy to be changed.

Barite grinding process (200~325mesh)
Barite raw materials are firstly crushed by jaw crusher to specified size, and then elevated into a hopper. Then vibrating feeder sends evenly and continuously the materials into the grinding chamber for powder processing.

The ground barite grains are carried by air from the blower into the classifier for classification. The finer powers are blown into cyclone collector, and the rough grains will be recycled back into the grinding chamber for further grinding, forming a closed circuit. Final products of 200~325mesh in size are poured out through out-put valve.
