Mobile crushing plants are built ready-mounted on their own travel gear. Semi-mobile plants, on the other hand, are moved from one location to the next as a piggyback load on separate haul units. Each crushing plant comes ready to operate with its own feed hopper, feed conveyor, discharge conveyor and material transfer belt. The size and design of the crusher naturally depends upon the work that it is intended for.
Semi-mobile crushing plants are always to be recommended when a change of location in long periods is required in order to optimize the raw material transportation- and operational-costs of the quarry department.

Sep 03, 2011 · Silica gel 60 (0.063–200 mm) and Florisil 60 were obtained from Merck (Darmstadt, Germany). Florisil was heated at 500 °C for 4 h before use. Silver nitrate impregnated silica gel (10%) was prepared by mixing silica gel with silver nitrate water solution and drying the obtained mixture at 130 °C in the dark.
COMPARISON OF THE EFFECTS OF WATER AND THERMAL PROCESSING ON
Many processing methods used in households and at food plants have been reported to affect, albeit differently, the pesticide level in foods. Most food processing techniques and methods usually reduce residual amounts of pesticides, but some may cause an increase in the residue content due to the concentration effect.
Pre concentration of pesticide residues in environmental
ABSTRACT: The silica nanoparticles prepared by stober’s mechanism by reaction of tetraethylorthosilicate (TEOS) with ammonia was tested for their adsorption capacity in the pre-concentration of residues of pesticides in water.
AEROSIL® fumed silica and SIPERNAT® specialty silica
SIPERNAT ® specialty silica converts additives or actives that usually appear as liquid or pasty substance into free flowing powders. In contrast to this AEROSIL ® fumed silica acts as rheology modifier for liquid pesticide formulations. Insoluble active ingredients in liquid pesticide formulations show settling effects and reduced efficiency.
