Dry mortar mixers (also known as horizontal dry mortar mixers) mainly consist of a mixing host, drive unit, sealing system, and safety protection devices. Based on the number of mixing shafts, they can be classified as single-shaft, double-shaft, triple-shaft, and quadruple-shaft types; based on the host unit type, they are mainly horizontal and vertical, with the horizontal structure being widely used due to its high mixing uniformity.
Core components of some dry mortar mixers include: shaft end seals using micro-grease rubber sealing technology; bearings separated from shaft end seals; spare sealing rubber and a centralized lubrication system; and a safety valve added to the oil seal of the shaft end bearing skeleton. The mixing device uses a solid shaft and high-chromium alloy wear-resistant blades, the blade surface of which can be overlaid with tungsten carbide. The mixing tank body is made of high-wear-resistant alloy steel plate, and wear-resistant lining plates can also be installed inside the tank.
Safety features include: an electronic safety lock that automatically cuts off the mixer's power when opened; a safety guard to prevent pinching or entanglement injuries during operation; a centralized oil injection system; and a pneumatic online sampler that allows real-time sampling of the material being mixed inside the machine without affecting its normal operation.
Furthermore, some improved designs include an easy-to-clean internal scraper structure for removing material adhering to the drum wall. Some mixers are integrally encapsulated and utilize a design with one main motor and multiple high-speed motors working in tandem.
