Hopper Design Principles

δ φ Jenike [1] found that the hopper angle required to allow flow along the walls depends on the friction between the powder and the walls, the friction between powder particles, and the geometry of the hopper.Design charts originally developed by Jenike [1] provide allowable hopper angles for mass flow, given values of the wall friction angle and the effective angle of

What Are Gunite and Shotcrete?

30/9/2018With the gunite method, the dry concrete ingredients are placed into a hopper and then pushed out pneumatically through a hose to a nozzle. The nozzle operator then controls the addition of water at the nozzle, turning the dry ingredients into concrete that is fully mixed by the time the material hits the host surface.

Cement Mixer/Research Development

A basic cement mixer, for pouring slabs for smaller foundations, is an excellent place to start. A drum on a frame, with a lever that rotates the drum 180 degrees, with the drum connected to two gears (or one gear with teeth that turn parts on exterior of drum) connected to a motor, is all that is necessary to get a basic mixer running.

The hopper must be a minimum height of 100mm and have a ratio of 1:3 (height of hopper: length of pour). Grout can also be pumped from the centre of the bearing plate where it spreads to the outside equally on all sides. A peristaltic pump is used for resin grouts and a diaphragm or worm pump for cement grouts.

One method to prevent an arch developing is to make the discharge hole from the hopper so large that the arch will collapse into the opening because the side wall is not present to provide support. In existing silos, the size of this hole can be determined by viewing the position on the hopper wall at which the arch is supported and adding an additional 20% to the measurement.

The tremie concrete placement method uses a vertical or nearly vertical pipe, through which concrete is placed by gravity feed below water level. [4] The lower end of the pipe is kept immersed in fresh concrete so that concrete rising from the bottom displaces the water, thus limiting washing out of the cement content of the fresh concrete to the exposed upper surface.
