“…Also, it is resistant to temperatures ranging from 260-1200 • C. Due to the remarkable physical characteristics of EV, various researchers have attempted to incorporate the light-weight material in the production of fired clay bricks to investigate the corresponding physical and mechanical properties. [19][20][21][22][23][24][25][26][27] In a recent study, EV (2%-10% by wt.) was investigated as an addition in porous clay bricks at firing temperatures varying from 900 to 1000 • C. 19 The addition of EV in bricks resulted in lower density, compressive strength, and thermal conductivity properties.…”

In the present study, the suitability of using water treatment sludge (WTS) as the main raw material and expanded vermiculite (EV) as aggregate in the production of fired bricks was investigated. Mixtures containing between 75%-100% WTS by weight (wt.) and 5%-25% EV by wt. were prepared at various proportions. The mixtures were compressed under 40 MPa pressure and fired at 1000 • C. It was found the incorporation of EV in fired bricks resulted in a decrease in thermal conductivity, compressive strength, and bulk density and an increase in apparent porosity and water absorption. For the addition of 5%-25% EV by wt., bulk density ranged between 2.01 and 1.69 kg/m 3 , compressive strength 19.3 and 8.3 MPa, water absorption 21.1% and 10.1%, and thermal conductivity 0.678 and 0.374 W/m-K, respectively. Based on the promising physical and mechanical properties, fired bricks incorporating WTS and EV can potentially offer an alternative to the traditional production of clay bricks while adhering to the principle of a circular economy.

A method for assessing the wear resistance of round impact elements of a disintegrator is considered using the example of grinding highly abrasive mica-crystalline materials (expanded vermiculite and its concentrate) in a disintegrator. A constructive method for protecting the working surfaces of impact elements from abrasive wear when dispersing similar materials in a disintegrator of a developed design is presented. Using mathematical expressions to estimate the wear parameters of the impact elements of the mill, experimental values of the wear of the impact elements were obtained depending on the linear speed of the impact element, the reduced productivity of the disintegrator, the weighted average size of the crushed particles, the strength of the crushed raw materials and the hardness of the material from which the impact elements are made. The differentiated influence of variable factors on the process of abrasive wear of the surfaces of the impact elements of the disintegrator has been determined. Using a graphical interpretation of the results of experimental studies of the process of abrasive wear of the impact elements of the disintegrator, it was established that the wear of the impact elements mainly depends on the productivity of the unit (mill throughput). As the productivity of the disintegrator increases, the specific wear of the working elements decreases due to a decrease in the flow density of the moving material inside the mill, regardless of its high absolute speed inside the grinding chamber. In order to reduce the surface abrasive wear of the impact elements of the disintegrator, the effectiveness of using special protective bushings made of baddeleyite-corundum materials, resistant to abrasive wear by silicate mica-crystalline rocks, was proposed and experimentally confirmed. A comparison was made of the proposed design solution for protecting the working surfaces of impact elements with previously used impact elements made of grade 45 steel hardened to HRC 50.
