As the natural sand and gravel raw materials in nature are non-renewable resources, in order to meet the large demand of construction and road engineering, we can use artificial sand to replace the natural sand and gravel raw materials. The following Jiaozuo Zhongxin Heavy Industry will introduce you to the mechanism sand aggregate. In the production process, how to effectively control its quality and production costs.
First, the quality of control sand
1.Grit size of control mechanism
We can control the grain size of the machine sand through the screening process. The main basis of the quality of the machined sand aggregate is the particle size and gradation requirements of the material. High-efficiency crushing equipment, vibrating screens and appropriate square-hole screens are used to control the grain size of the sand to a certain extent.
2. Controlling sand content of mud
Strictly control the inclination angle of the screen and the amount of raw materials to be screened. At the same time, it is equipped with a stable flushing system and uniformly arranged the water spray holes. It is necessary to adjust the appropriate water pressure when washing sand and gravel, so that the sprayed water can be evenly covered The screen mesh allows the materials to be fully cleaned, while reducing the mud content of the machine-made sand materials.
3.Protection mechanism sand finished product
When the sand aggregate is transported by the belt conveyor to the finished product storage, a separation wall can be set up near the finished product stack to partition the finished product to prevent mixing. Product labels can be set at the place where the finished materials are stacked. The spacing between the materials should be *er than 3m. The products should be arranged neatly and orderly. A drainage system can also be set up to ensure that the washed sand aggregates can be quickly dewatered after entering the pile. To meet the water content requirements for the production of construction materials.
Second, control sand production costs
1. Determine a reasonable production scale and purchase appropriate equipment
Before purchasing machinery sand production line equipment, you must * determine the production scale and output requirements. It is also necessary to choose a suitable manufacturer of sand production line equipment, and select a strong, reputable, and responsible manufacturer. Irrational equipment configuration and production schemes will affect the production cost of sand making.
2. Timely maintenance to reduce equipment failure rate
After the sand production line is completed, reasonable personnel will be deployed to regularly repair and maintain the production line equipment. A shift system can be formulated to timely add lubricants, stretch the conveyor belt and fastening bolts, etc., and check the sand production in a timely manner. Regular maintenance of the parts of the equipment can not only reduce the failure rate of the equipment, but also save maintenance costs.
3. Improve material usage and reduce fine sand loss
Production materials are a relatively high part of the cost of the entire production process. Therefore, to a certain extent, increasing the utilization rate of materials can not only reduce the waste of mechanical sand aggregate, but also reduce production costs. Therefore, care must be taken not to waste materials during the sieving of materials and finished products during storage and transportation. When using crushing equipment to clean crushed materials, pay attention to the recovery of fine sand to reduce the loss of sand and gravel during the washing process.
