Detailed Description
The invention will now be described in detail with reference to the drawings and specific examples.
Example 1
A rapid testing method for slurry density comprises the steps of adding water into an overflow bucket with the mass of 630g, adding 860g of total slurry into a container, pouring out a part of total mass of the residual slurry into the container, changing the reading of a basket balance into 754g, and calculating the slurry density according to a formula:
in this embodiment, the quality of the slurry poured into the overflow bucket is not limited, but it is necessary to ensure that the overflow port overflows with clean water.
The slurry density test method adopts the rapid slurry density test method and comprises the following steps:
1) The overflow barrel is filled with water and hung under the basket-hanging balance, and the reading m of the balance is recorded 0 ；
2) Filling slurry into a watertight container, wiping the surface of the container, and weighing m 1 (100～200g)；
3) Pouring the slurry into the overflow bucket stably and slowly, and observing the overflow port to ensure that only clean water flows out of the overflow port;
4) Weighing the total weight m of the residual slurry and the container after the operation of the step three 2 ；
5) Recording the reading m of the basket balance 3 ；
6) The relative density of the slurry was calculated:
wherein ρ -slurry density, kg/m 3
m 0 -water adding quality of the overflow barrel, g;
m 1 adding the mass of the slurry into a container, and g;
m 2 adding the mass of the container into the residual slurry, and g;
m 3 pouring the slurry, and hanging a basket balance for reading g;
ρ w density of water, kg/m 3 。
In the rapid testing method of the slurry density, slurry can be directly poured into the overflow basket, and the slurry density is rapidly calculated by utilizing the change of the readings before and after the basket balance.
