Product Overview
The CRUSTION MB series Barmac sand maker is a new-generation, high-efficiency sand-making equipment developed by CRUSTION in light of China’s actual sand-making production conditions. CRUSTION’s core team boasts nearly 30 years of experience in the R&D, manufacturing, and application of crushing equipment, mastering core technologies in mechanics, hydraulics, and electrical control. Its products have earned widespread acclaim in high-end markets such as Europe, the United States, and Australia. This series of equipment is widely used for medium and fine crushing (sand making) operations on various hard and brittle materials, including rock, abrasives, refractory materials, cement clinker, quartz, iron ore, and concrete aggregates.

Working principle
The CRUSTION MB series sand maker adopts the “stone-on-stone” crushing principle. After material enters the crusher through the feed hopper, a distributor splits the flow: part of the material passes through the central feed pipe into the high-speed rotating impeller and is accelerated to a high velocity before being thrown out; the other part enters the vortex crushing chamber from the bypass on the outer side of the impeller. The high-speed material ejected by the impeller collides with the material inside the vortex chamber, achieving crushing. Meanwhile, a material lining layer forms within the vortex crushing chamber, confining the crushing action solely to the material itself and providing wear-resistant self-lining.
Core Advantages
1. High crushing ratio, adjustable discharge particle size
This series of sand-making machines features a high crushing ratio, with discharge particle size flexibly adjustable to meet production requirements. The finished sand has uniform particle size and high compressive strength.
2. Modular hammerhead design reduces costs
With a modular hammerhead design, only the worn portion needs to be replaced, reducing operating costs by more than 30%. Additionally, an auxiliary hammerhead is included to effectively prevent damage to the vertical liner when the main hammerhead wears out.
3. Wide range of applicable materials
It can process soft, medium-hard, and extremely hard materials and is widely applicable to river pebbles, limestone, granite, basalt, diabase, iron ore, quartz, and various other materials.
4. Less affected by material moisture
It can handle materials with a moisture content of around 8%, offering greater adaptability.
5. Combines fine crushing and coarse grinding functions
The equipment not only offers fine crushing capabilities but also provides coarse grinding functions, making it a versatile, multi-purpose machine.

| Note: In the table, the throughput at a linear speed of 70 m/s has a lower limit corresponding to center feed only (0% split) and an upper limit corresponding to center feed plus a 30% split. When rotor speed decreases, throughput increases, and vice versa; the linear speed range is 60–75 m/s. Use a higher speed when sand-making is the primary operation and a lower speed when shaping is the primary operation. The reference weight in the table excludes the support leg assemblies, which are optional. The MC 9 can reach a maximum installed power of 2 × 315 kW, but only under the most ideal operating conditions. | |||||
