Who We Are

We are a manufacturer specializing in the production of mine crushing equipment.

CBM is an international company group specialized in R&D, production, sales and service of the minerals and stone crushing machines, VU sand making system as well as industrial grinding mills. Not only is our group company the first batch of high technology key enterprise, but also it is the main production and export base for high-end mining machines. It has established 20 overseas business institutions and branches, with the products exported to more than 160 countries and regions throughout the world. China Customs’data (2009一2014) shows: Exports from Shibang Industrial Technology Co.Ltd ranked the Top one for six years in a row in China’s mining machinery industry.

Should you buy a Stock Blender for your Open Mill

The Stock Blender is an add-on accessory mounted on top of an open two-roll mill It aids in rubber blending by pulling the mix compound from the front roll of the mill and guiding it to the nip gap between the two mill rolls Structurally this machine assembly consists of a blender roll a carriage unit with guide rolls pressure roll and rear roll along with required automation


The mixing is often done on a two-roll mill open mill A mill consists of two horizontally placed hollow metal cylinders rolls rotating towards each other The distance/gap between the mill rolls nip can be varied typically between 2 to 20 mm
