Mechanized construction of dry-mixed mortar in a dry mix mortar plant presents outstanding advantages and high technical value. It effectively improves the uniformity of dry-mixed mortar produced by the dry mix mortar plant, guarantees construction quality, and achieves high-quality and high-efficiency construction. The ready mix mortar plant also cuts overall comprehensive costs through mechanized operation, realizes zero dust pollution and zero construction waste, greatly reduces labor intensity, and truly achieves civilized construction. A well-equipped ready mix mortar plant relies on professional equipment to ensure smooth construction, and at present, the main construction equipment for dry-mixed mortar in a ready mix mortar plant consists of mortar mixers and mortar pumps.
Mortar Mixers
In a ready mix mortar plant, mortar mixers are the core equipment for mixing dry-mixed mortar, mainly classified into two types: continuous mixing type and intermittent mixing type. The continuous mortar mixer, a key component of an advanced ready mix mortar plant, features small overall dimension and compact structure. The mortar mixer integrates paddle stirring and screw compression into one unit, with functions of mortar mixing, blending and conveying. This type of mortar mixer can be directly installed under bulk storage silos of a ready mix mortar plant and equipped with automatic feeding and metering devices. It is an integrated construction equipment widely applied in overseas ready mix mortar plants, while such a mortar mixer is still under research and development in domestic dry mix mortar plants. At present, small intermittent vertical-shaft or horizontal mortar mixers equipped with automatic feeding and metering devices are commonly adopted in domestic dry mix mortar plants to complete the mixing and blending process of dry-mixed mortar.
Mortar Pumps
Mortar pumps are another essential equipment in a dry mix mortar plant, mainly divided into three categories: squeeze type, plunger type and screw type. The squeeze mortar pump, widely used in small and medium-sized dry mix mortar plants, has a simple structure and convenient maintenance, but its squeeze rubber hose has a short service life and needs frequent replacement. The plunger mortar pump, suitable for large-scale dry mix mortar plants, delivers high working pressure and long conveying distance; however, it has a relatively complex structure, and its sealing parts are prone to wear and also require regular replacement. Both squeeze and plunger mortar pumps are domestically manufactured products suitable for domestic dry mix mortar plants, with easy maintenance and competitive price. They are ideal mortar pumps for mortar pouring and grouting construction in a dry mix mortar plant, and can also be used for shotcreting operation. The screw mortar pump, a high-end equipment for advanced dry mix mortar plants, requires high machining and manufacturing precision. It features small size, compact structure, excellent working performance and long service life, making it the preferred mortar pump for high-efficiency dry mix mortar plants overseas.
