FAQs
My site is not in an ordinary location. Could you provide a corresponding plan to build a dry mortar production line for me?
Of course, we can provide one-on-one customized services to help you not only realize the site construction but also achieve cost reduction and efficiency improvement.
What sand-making equipment is used in the dry mortar production line?
In the realm of dry mortar production, Zhongqinglin Heavy Industry's VK Sand Making Machine has emerged as a core equipment that commands industry attention, thanks to its distinctive design and exceptional performance.
What kind of sand making machine are you using? Is the crushing effect good?
We use vertical shaft impact crushing equipment, and its crushing effect ensures high-quality particle shape. By allowing materials to break along their natural textures, the produced aggregates are cubic, with low content of needle-like and flake-like particles and uniform gradation, laying a solid foundation for high-quality mortar.
What should I do if the aggregate conveyed by the belt is uneven?
It is necessary to adjust the unloading sequence of aggregates to ensure that sand is unloaded last. This is like planning a reasonable driving route for a road, allowing various aggregates to "travel" on the belt in an orderly manner. Secondly, adjust the unloading time interval of various aggregates according to the distribution of aggregates on the belt to ensure that the materials on the belt are continuously and evenly distributed.
What problems will occur with dry-mix mortar admixtures in high-temperature weather?
Water-retaining components such as cellulose ether and starch ether will absorb moisture in the air and agglomerate when the humidity exceeds 80%. This directly causes the water retention of the mortar to decrease by more than 30%, making it prone to bleeding and delamination during construction, and increasing the risk of surface cracking after hardening by 40%.
What problems will occur with dry-mix mortar raw materials in high-temperature weather?
Cement, lime and other cementitious materials have extremely strong hygroscopicity. In high-humidity environments, their surfaces will quickly absorb moisture to form calcium hydroxide lumps. When caking is severe, lumps with a diameter of over 5mm may block the discharge port of the screw conveyor, causing the measurement deviation of the batching scale to exceed ±2%, and may even cause jamming and damage to the blades of the mixing equipment. If the storage silos for admixtures such as fly ash and slag powder are not tightly sealed, in an environment with a relative humidity >75%, fine particles will agglomerate into spherical particles with a diameter of 1-3 cm due to surface tension. These "pseudo particles" tend to form an "arch bridge" structure at the cone of the silo during the falling process, resulting in material flow interruption. If the initial moisture content of aggregates such as fine sand and quartz sand exceeds 3%, the moisture is difficult to naturally evaporate in a hot and humid environment. When these high-moisture aggregates are mixed with cement, a "pre-hydration" phenomenon may occur: the fluidity of the mortar decreases by 20%-30% when it leaves the mixer, the setting time is shortened by 1-2 hours, and in severe cases, "false setting" occurs, resulting in honeycombing and pitting on the construction surface.
Can engineers be sent to our site for installation and training?
We’ll send experienced engineers to the customer's site to guide equipment installation and debug the equipment. We will also provide installation instructions, layout drawings, assembly drawings, etc.
What is the positioning and cost performance of your products?
We have professional engineers, skilled production workers, high-standard quality inspection, and pre-sales and after-sales service teams with effective communication. We can assemble and test all the equipment and pack them carefully before delivery. Maybe our price is not the lowest, but we pursue the best service and quality and we are definitely your most suitable and trustworthy partner.
Are you a factory, a design company, or a trading company?
We are a manufacture factory with our own mechanical and project design engineers. We can provide customized solution design according to customers’ requirement, and full-process services such as early project discussion, scheme design, equipment selection, site planning, equipment layout, transportation and delivery, installation and commissioning.
Can you provide technical and process guidance?
Yes. We have rich experience in mortar production, and we will customize the equipment according to your needs and provide a full range of project guidance. We can reasonably design the layout and site planning according to the size of your workshop, and provide technical support for mortar formulas.
