Product Overview
Rod sand grinder, made of wear-resistant materials, has a long service life. Adopting high-precision special mechanical seals, the sealing effect is reliable. Adopting a dual cooling structure of outer jacket and inner rotor, effectively reducing the grinding temperature. Adjustable grinding cylinder volume to change bead loading and improve grinding efficiency. Specially designed explosion-proof control components that meet reliable explosion-proof requirements. Electrical control system and fault alarm system. Various feeding pumps are available for selection, and can be optionally selected for various materials.
Design principle:
The sand mill adopts an eccentric disc grinding structure and is arranged in a certain order. This system overcomes the disadvantage of uneven distribution of grinding media in traditional grinding machines, enabling energy transfer of grinding media and high grinding efficiency. It uses a double end face forced cooling mechanical seal with good sealing effect and reliable operation. The separation system adopts a high flow rate LDC dynamic grid slot separator, which will not cause blockage of the discharge port under high flow conditions, with a flow area of 0.05-2.0mm, and can use grinding media with a gap range of 0.1mm or more.
Rod type closed sand mill
The sand mill adopts a disc or rod pin design with a closed inner cavity. The grinding discs are installed on the mixing shaft in a certain order, overcoming the disadvantages of uneven distribution of grinding medium and poor particle size distribution after grinding in traditional horizontal sand mills. The material enters the grinding chamber under the action of the feed pump, and the inlet is designed at one end of the drive connection flange. The flow direction of the material is opposite to the bottom end of the mechanical bearing, greatly reducing the pressure on the mechanical seal and extending its service life. During the high-speed operation of the eccentric disc of the mixing shaft, the mixture of material and grinding medium undergoes efficient relative motion. As a result, the solid particles of the material are effectively dispersed, sheared and ground. After passing through the dynamic high flow rotor gap separation filter, the product is obtained. Depending on the grinding process of the product, independent batch cyclic grinding or series grinding processes can be used.
