SHREDDERS


Four shaft Four shaft shredders are designed for more consistent and finer particles. They are intended for more heavy- duty shredding and built to withstand tough environments.


Hickling continues, “The Doppstadt DW 3060 is a single shaft which comes with 42 bolt on teeth directly driven from the engine. “The shredding is done by a 3m roller which rotates at


28rpm. The teeth, which are made from wear resistant steel, tear even the toughest material through the shedding comb with ease. The comb also opens automatically if necessary in order to avoid damages by large un-shreddable contaminants.” Competency is improved overall according to Hickling,


“It dramatically improves the efficiency of the site. If we didn’t have the shredder on site, we could not operate as effectively as we do. The machine is also very versatile and allows us to use it across multiple applications throughout the plant.” Implementing the shredder into the business was a


straightforward process, Hickling continues, “When the machine was purchased, Blue Machinery Central trained all our staff individually. This was done quickly and easily as the machine is so user-friendly. “The operators of the machine find the Doppstadt very


easy to use and maintain due to the bulk of the parts being easily replaceable wear parts. “We didn’t experience any challenges at all when implementing this piece of equipment due, to its


manoeuvrability across the site and ease of use.” As with any product, waste business


owners need to know that durability and robustness are key attributes of their purchase. Hickling continues, “Our previous machine lasted six years and was used six days per week. We always give the machine a life of six years before we look to replace with a new one. We know however due to the demand of Doppstadt equipment the residual value will be high helping us to invest in a new Doppstadt slow speed.” Similarly, other factors in the purchase


decision-making process are repairs and general upkeep. Hickling says, “The maintenance is very easy with the Doppstadt machines due to its interchangeable teeth and combs. This reduces downtime for maintenance, ensuring we are up and running again in no time. The machine is very reliable due to us having a service contract with the manufacturers who clearly know the machines inside out.” “Reliability is key for our business, as the


shredder is such a vital part of our overall process. Doppstadt are renowned for their accessibility to all key parts of the machine, meaning they are easy for the engineers to work on.” For waste businesses, continued return on


investment is paramount to growth. Metrics enable waste decision-makers to conclude whether or not the machinery has proved to be a financial loss or gain. In this instance, implementing a shredder into their waste business was a productive decision. Hickling continues, “The machine is hungry, achieving 60tph. When you take this in to consideration and the resale value of Doppstadt machines, it was by far the most commercially viable option for the business.” When asked his thoughts overall on


implementing a shredder into their waste business, Hickling says it was a constructive decision, “When purchasing a shredder, there are a lot of things to consider, which are key to making the overall investment viable for the business.” “Back up and service and the availability of


spare parts is vital when purchasing capital equipment. Not only did we decide to purchase a Doppstadt, but our overall decision to purchase this particular piece of machinery was also based on the dealer, their ability to get to site if something goes wrong and if parts are required, how long it takes to get the parts to site. “The actual machine itself is only part of the


jigsaw. Consideration to these other elements is a critical part of the decision making process.”
